Shoot apical meristem and cotyledon formation during Arabidopsis embryogenesis: interaction among the CUP-SHAPED COTYLEDON and SHOOT MERISTEMLESS genes. (1/470)

The shoot apical meristem and cotyledons of higher plants are established during embryogenesis in the apex. Redundant CUP-SHAPED COTYLEDON 1 (CUC1) and CUC2 as well as SHOOT MERISTEMLESS (STM) of Arabidopsis are required for shoot apical meristem formation and cotyledon separation. To elucidate how the apical region of the embryo is established, we investigated genetic interactions among CUC1, CUC2 and STM, as well as the expression patterns of CUC2 and STM mRNA. Expression of these genes marked the incipient shoot apical meristem as well as the boundaries of cotyledon primordia, consistent with their roles for shoot apical meristem formation and cotyledon separation. Genetic and expression analyses indicate that CUC1 and CUC2 are redundantly required for expression of STM to form the shoot apical meristem, and that STM is required for proper spatial expression of CUC2 to separate cotyledons. A model for pattern formation in the apical region of the Arabidopsis embryo is presented.  (+info)

Enhancer-like properties of an RNA element that modulates Tombusvirus RNA accumulation. (2/470)

Prototypical defective interfering (DI) RNAs of the plus-strand RNA virus tomato bushy stunt virus contain four noncontiguous segments (regions I-IV) derived from the viral genome. Region I corresponds to 5'-noncoding sequence, regions II and III are derived from internal positions, and region IV represents a 3'-terminal segment. We analyzed the internally located region III in a prototypical DI RNA to understand better its role in DI RNA accumulation. Our results indicate that (1) region III is not essential for DI RNA accumulation, but molecules that lack it accumulate at significantly reduced levels ( approximately 10-fold lower), (2) region III is able to function at different positions and in opposite orientations, (3) a single copy of region III is favored over multiple copies, (4) the stimulatory effect observed on DI RNA accumulation is not due to region III-mediated RNA stabilization, (5) DI RNAs lacking region III permit the efficient accumulation of head-to-tail dimers and are less effective at suppressing helper RNA accumulation, and (6) negative-strand accumulation is also significantly depressed for DI RNAs lacking region III. Collectively, these results support a role for region III as an enhancer-like element that facilitates DI RNA replication. A scanning-type mutagenesis strategy was used to define portions of region III important for its stimulatory effect on DI RNA accumulation. Interestingly, the results revealed several differences in the requirements for activity when region III was in the forward versus the reverse orientation. In the context of the viral genome, region III was found to be essential for biological activity. This latter finding defines a critical role for this element in the reproductive cycle of the virus.  (+info)

Posttranslational removal of the carboxyl-terminal KDEL of the cysteine protease SH-EP occurs prior to maturation of the enzyme. (3/470)

SH-EP is a cysteine protease from germinating mung bean (Vigna mungo) that possesses a carboxyl-terminal endoplasmic reticulum (ER) retention sequence, KDEL. In order to examine the function of the ER retention sequence, we expressed a full-length cDNA of SH-EP and a minus-KDEL control in insect Sf-9 cells using the baculovirus system. Our observations on the synthesis, processing, and trafficking of SH-EP in Sf-9 cells suggest that the KDEL ER-retention sequence is posttranslationally removed either while the protein is still in the ER or immediately after its exit from the ER, resulting in the accumulation of proSH-EP minus its KDEL signal. It is this intermediate form that appears to progress through the endomembrane system and is subsequently processed to form mature active SH-EP. The removal of an ER retention may regulate protein delivery to a functional site and present an alternative role for ER retention sequences in addition to their well established role in maintaining the protein composition of the ER lumen.  (+info)

Cucumber cotyledon lipoxygenase during postgerminative growth. Its expression and action on lipid bodies. (4/470)

In cucumber (Cucumis sativus), high lipoxygenase-1 (LOX-1) activity has been detected in the soluble fraction prepared from cotyledons of germinating seeds, and the involvement of this enzyme in lipid turnover has been suggested (K. Matsui, M. Irie, T. Kajiwara, A. Hatanaka [1992] Plant Sci 85: 23-32; I. Fuessner, C. Wasternack, H. Kindl, H. Kuhn [1995] Proc Natl Acad Sci USA 92: 11849-11853). In this study we have investigated the expression of the gene lox-1, corresponding to the LOX-1 enzyme. LOX-1 expression is highly coordinated with that of a typical glyoxysomal enzyme, isocitrate lyase, during the postgerminative stage of cotyledon development. In contrast, although icl transcripts accumulated in tissue during in vitro senescence, no accumulation of lox-1 mRNA could be observed, suggesting that lox-1 plays a specialized role in fat mobilization. LOX-1 is also known to be a major lipid body protein. The partial peptide sequences of purified LOX-1 and lipid body LOX-1 entirely coincided with that deduced from the lox-1 cDNA sequence. The data strongly suggest that LOX-1 and lipid body LOX-1 are derived from a single gene and that LOX-1 can exist both in the cytosol and on the lipid bodies. We constructed an in vitro oxygenation system to address the mechanism of this dual localization and to investigate the action of LOX-1 on lipids in the lipid bodies. LOX-1 cannot act on the lipids in intact lipid bodies, although degradation of lipid body proteins, either during seedling growth or by treatment with trypsin, allows lipid bodies to become susceptible to LOX-1. We discuss the role of LOX-1 in fat mobilization and its mechanism of action.  (+info)

Regulation of nitrite reductase by light and nitrate in the cotyledons of hot pepper (Capsicum annuum L.). (5/470)

Light and nitrate are the major factors regulating the nitrite reductase (NiR) amongst various environmental and metabolic cues in plants. Hot pepper was used to investigate this regulatory mechanism of the NiR gene expression and its dependency on light and nitrate. The major results from this study are: (I) the nir partial clone (581 bp) obtained from hot pepper genomic DNA by degenerative polymerase chain reaction exhibited an amino acid sequence that is highly homologous with other plants. (II) Genomic DNA blot analysis and the NiR electrophoretic assay revealed that a small multigene family encodes NiR, which exists at least in two isoforms. (III) The light-mediated increase of NiR activity is correlated with the nitrate concentration, showing saturation kinetics above 50 mM of nitrate. (IV) Exogenous nitrate was required for the appearance of nir transcripts, but not for the enzyme activity. These results suggest that the gene expression of NiR in hot pepper is determined by the presence of nitrate at the transcriptional level. Furthermore, light has a synergistic effect on the action of nitrate on NiR levels.  (+info)

Identification of a cis-regulatory element involved in phytochrome down-regulated expression of the pea small GTPase gene pra2. (6/470)

The pra2 gene encodes a pea (Pisum sativum) small GTPase belonging to the YPT/rab family, and its expression is down-regulated by light, mediated by phytochrome. We have isolated and characterized a genomic clone of this gene and constructed a fusion DNA of its 5'-upstream region in front of the gene for firefly luciferase. Using this construct in a transient assay, we determined a pra2 cis-regulatory region sufficient to direct the light down-regulation of the luciferase reporter gene. Both 5'- and internal deletion analyses revealed that the 93-bp sequence between -734 and -642 from the transcriptional start site was important for phytochrome down-regulation. Gain-of-function analysis showed that this 93-bp region could confer light down-regulation when fused to the cauliflower mosaic virus 35S promoter. Furthermore, linker-scanning analysis showed that a 12-bp sequence within the 93-bp region mediated phytochrome down-regulation. Gel-retardation analysis showed the presence of a nuclear factor that was specifically bound to the 12-bp sequence in vitro. These results indicate that this element is a cis-regulatory element involved in phytochrome down-regulated expression.  (+info)

Barley coleoptile peroxidases. Purification, molecular cloning, and induction by pathogens. (7/470)

A cDNA clone encoding the Prx7 peroxidase from barley (Hordeum vulgare L.) predicted a 341-amino acid protein with a molecular weight of 36,515. N- and C-terminal putative signal peptides were present, suggesting a vacuolar location of the peroxidase. Immunoblotting and reverse-transcriptase polymerase chain reaction showed that the Prx7 protein and mRNA accumulated abundantly in barley coleoptiles and in leaf epidermis inoculated with powdery mildew fungus (Blumeria graminis). Two isoperoxidases with isoelectric points of 9.3 and 7.3 (P9.3 and P7.3, respectively) were purified to homogeneity from barley coleoptiles. P9.3 and P7.3 had Reinheitszahl values of 3.31 and 2.85 and specific activities (with 2,2'-azino-di-[3-ethyl-benzothiazoline-6-sulfonic acid], pH 5.5, as the substrate) of 11 and 79 units/mg, respectively. N-terminal amino acid sequencing and matrix-assisted laser desorption/ionization time-of-flight mass-spectrometry peptide analysis identified the P9. 3 peroxidase activity as due to Prx7. Tissue and subcellular accumulation of Prx7 was studied using activity-stained isoelectric focusing gels and immunoblotting. The peroxidase activity due to Prx7 accumulated in barley leaves 24 h after inoculation with powdery mildew spores or by wounding of epidermal cells. Prx7 accumulated predominantly in the epidermis, apparently in the vacuole, and appeared to be the only pathogen-induced vacuolar peroxidase expressed in barley tissues. The data presented here suggest that Prx7 is responsible for the biosynthesis of antifungal compounds known as hordatines, which accumulate abundantly in barley coleoptiles.  (+info)

Blue light-directed destabilization of the pea Lhcb1*4 transcript depends on sequences within the 5' untranslated region. (8/470)

Pea seedlings grown in continuous red light accumulate significant levels of Lhcb1 RNA. When treated with a single pulse of blue light with a total fluence >10(4) micromol m(-2), the rate of Lhcb1 transcription is increased, whereas the level of Lhcb1 RNA is unchanged from that in control seedlings. This RNA destabilization response occurs in developing leaves but not in the apical bud. The data presented here indicate that the same response occurs in the cotyledons of etiolated Arabidopsis seedlings. The blue light-induced destabilization response persists in long hypocotyl hy4 and phytochrome phyA, phyB, and hy1 mutants as well as in far-red light-grown seedlings, indicating that neither CRY1 (encoded by the hy4 locus) nor phytochrome is the sole photoreceptor. Studies with transgenic plants indicate that the destabilization element in the pea Lhcb1*4 transcript resides completely in the 5' untranslated region.  (+info)

During Arabidopsis embryo development, cotyledon primordia are generated at transition stage from precursor cells that are not derived from the embryonic shoot apical meristem (SAM). To date, it is not known which genes specifically instruct these precursor cells to elaborate cotyledons, nor is the role of auxin in cotyledon development clear. In laterne mutants, the cotyledons are precisely deleted, yet the hypocotyl and root are unaffected. The laterne phenotype is caused by a combination of two mutations: one in the PINOID (PID) gene and another mutation in a novel locus designated ENHANCER OF PINOID (ENP). The expression domains of shoot apex organising genes such as SHOOT MERISTEMLESS (STM) extend along the entire apical region of laterne embryos. However, analysis of pid enp stm triple mutants shows that ectopic activity of STM does not appear to cause cotyledon obliteration. This is exclusively caused by enp in concert with pid. In pinoid embryos, reversal of polarity of the PIN1 auxin ...
A cotyledon, or seed leaf, is a leaf that is stored in a seed. When the seed sprouts, the cotyledons are the first leaves that the plant has. Monocot plants have only one cotyledon, and other plants have two. Cotyledons often look very different from the other leaves, so they are not called true leaves. Plants use cotyledons to make sugars through photosynthesis. They use the sugars to keep true leaves growing. After a while, the cotyledons often die because the plant does not need them anymore. ...
Gazania plugs can be produced in 406, 288, or similar size trays.. Stage 1 (From sowing to radicle emergence): The optimal temperature for germination is 70 to 72¡ F, and it takes about three to five days for germination. Light is not required for germination and a medium covering of coarse-grade vermiculite is recommended at sowing to help maintain moisture around the seed for better germination.. Stage 2 (From radicle emergence to cotyledon expansion): After germination, the plugs can be grown at 68 to 72¡ F day and 60 to 62¡ F night temperatures. The light levels can be up to 2,500 foot-candles. Keep the media moisture level at medium wet during this stage. Start fertilizing the crop one to two times a week with 50- 75-ppm nitrogen using a well-balanced nitrate-form fertilizer with low phosphorous, maintaining the media EC at about 0.75.. Stage 3 (From cotyledon expansion to growth of all true leaves): The temperature and light levels can be maintained same as in stage 2, but the media ...

In Arabidopsis, hexokinase 1 (HXK1) acts as a glucose sensor to regulate gene expression and plant growth, a role distinct from its function in glycolysis; however, the mechanisms whereby HXK1 mediates glucose signaling have been unclear. After showing that a portion of Arabidopsis HXK was present in the nucleus, Cho et al. used proteomic and binary-interaction screens to identify two proteins--vacuolar H+-ATPase B1 (VHA-B1) and the 19S regulatory particle of proteasome subunit (RPT5B)--as nuclear-specific HXK1-interacting partners that formed a complex with HXK1. Genetic analysis revealed that vha-B1 and rpt5b loss-of-function mutants resembled the HXK1 gin2 (glucose-insensitive2) mutant: All three mutants were insensitive to repression of cotyledon expansion, chlorophyll accumulation, and leaf and root development in response to high-glucose conditions and showed growth retardation compared with wild-type plants under low-light, low-nutrient conditions. The gin2-like phenotypes of the vha-B1 ...

Plant cotyledons are a tissue that is particularly active in plastid gene expression in order to develop functional chloroplasts from pro-plastids, the plastid precursor stage in plant embryos. Cotyledons, therefore, represent a material being ideal for the study of composition, function and regulation of protein complexes involved in plastid gene expression. Here, we present a pilot study that uses heparin-Sepharose and phospho-cellulose chromatography in combination with isoelectric focussing and denaturing SDS gel electrophoresis (two-dimensional gel electrophoresis) for investigating the nucleotide binding proteome of mustard chloroplasts purified from cotyledons. We describe the technical requirements for a highly resolved biochemical purification of several hundreds of protein spots obtained from such samples. Subsequent mass spectrometry of peptides isolated out of cut spots that had been treated with trypsin identified 58 different proteins within 180 distinct spots. Our analyses indicate a high

The storage of food reserves in angiosperm seeds differs between monocots and dicots. In monocots, such as corn and wheat, the single cotyledon is called a scutellum; the scutellum is connected directly to the embryo via vascular tissue (xylem and phloem). Food reserves are stored in the large endosperm. Upon germination, enzymes are secreted by the aleurone, a single layer of cells just inside the seed coat that surrounds the endosperm and embryo. The enzymes degrade the stored carbohydrates, proteins and lipids, the products of which are absorbed by the scutellum and transported via a vasculature strand to the developing embryo. Therefore, the scutellum can be seen to be an absorptive organ, not a storage organ.. The two cotyledons in the dicot seed also have vascular connections to the embryo. In endospermic dicots, the food reserves are stored in the endosperm. During germination, the two cotyledons therefore act as absorptive organs to take up the enzymatically released food reserves, much ...

Materials and methods: Cowpea seeds were surface sterilized and allowed to germinate in petri dishes over moist filter papers. Immediately after germination they were divided into two groups. While one group was treated with Sucrose 30CH diluted with distilled water 1:500, the other group was treated with Ethanol 30CH, diluted with water 1:500. After treatment the seedlings were transferred to separate petri dishes and allowed to grow for 72 hours. Samples of seedlings from each treatment group were weighed, kept at 70o C for 24 hours and weighed again. Another sample from each group was analysed for their sugar content and protein content following Anthrone and Lowrys method, respectively [3]. Chlorophyll content was measured in situ by a chlorophyll-meter. Leaf and cotyledon sections were examined under a scanning electron microscope to see any changes in the epidermal cells of cotyledons and density and morphology of stomata ...

TY - JOUR. T1 - Expression and Automated Purification of Acetoacetyl CoA Thiolase from Sunflower Cotyledon. AU - Dyer, James H.. AU - Becker, James. AU - Geraldo, Victor. AU - Giron, Mario. PY - 2006/4. Y1 - 2006/4. N2 - In the sunflower (Helianthus annuus L.) cotyledons, two distinguishable thiolase activities have been identified: acetoacetyl CoA thiolase (AACT), specifically active during oxidation of short chain acetoacetyl CoA, and 3-oxoacyl CoA thiolase (OACT), active towards short, medium, and long-chain acyl CoAs. The purpose of this research was to optimize the purification of the AACT expressed in bacteria. Escherischia coli (E. coli) with the full-length sunflower AACT cDNA cloned into the expression vector pBAD-His B was induced for production of the AACT using 0.2% arabinose. Optimizing the conditions for protein purification is often an extremely empirical process requiring several iterations of a basic protocol each with specific changes. This iterative process was simplified ...
Analysis of the cot1 phenotype: Overexpression of GL1 results in the initiation of a few ectopic cotyledon trichomes and in a reduced number of adaxial leaf trichomes. To identify enhancers or suppressors of this dominant phenotype, homozygous 35S::GL1 (transformant 4-1) seeds were mutagenized with EMS (see materials and methods). An M2 population representing the equivalent of ~3300 M1 seeds was screened to identify plants with altered trichome distribution. The mutagenesis was successful because additional alleles of ttg (Larkinet al. 1994), dis, and zwi were obtained (data not shown). In the unmutagenized 35S::GL1 4-1 line used in this experiment, ~10% of plants normally contain cotyledon trichomes; however, plants with five or more trichomes on both cotyledons have not been seen in this population (M. D. Marks, unpublished results), and the presence of at least five trichomes on each cotyledon was used as the criterion to identify mutations. The cot1 mutation was isolated based on its ...
Seeds: Extremely small, weighting bout 0,01 mg. These small seeds (also known as dust diaspores) can be blown about like dust particles without any special devices for buoyancy. In this species, enormous numbers of seeds are produced at the cost of fewer, larger sized seeds . Because this plant occur abundantly in the arid areas and has specific habitat requirements, the production of increased numbers of seeds is essential to enhance the probability that at least some seeds will reach a favourable germination site. Except for their small size, these diaspores generally lack other appendages to further promote dispersal by wind. Several genera of the Crassulaceae, e.g. Crassula, Tylecodon and Cotyledon, occouring in the arid areas of southern Africa have very tiny dust-like seeds. The production of numerous dust-like seeds by desert species serves as an escape strategy to prevent mass consumption of seeds. These tiny seeds are carried by the wind to cracks and furrows in the soil and are then ...
Molecular studies of late embryogenesis and seed development have emphasized differential gene expression as a means of identifying discrete stages of embryogenesis. Little has been done to identify factors that regulate the length of a given developmental stage or the degree of overlap between adjacent developmental programs. We designed a genetic screen to identify mutations that disrupt late embryo development in Arabidopsis without loss of hormonal responses. One such mutation, fusca3 (fus3), alters late embryo functions, such as the establishment of dormancy and desiccation tolerance, and reduces storage protein levels. fus3 cotyledons bear trichomes, and their ultrastructure is similar to that of leaf primordia. Immature fus3 embryos enter germinative development, and the shoot apical meristems develop leaf primordia before seed desiccation begins. The cotyledons resemble leaf primordia, yet retain some cotyledon characteristics; thus, cotyledon- and leaf-specific functions are expressed ...

Experimental Morphology and Morphogenesis Then and Now: A Symposium in Memory of Elizabeth G. Cutter. Von Aderkas, Patrick [1]. Experimental ecological embryogenesis .. Elizabeth Cutter was interested in morphological and anatomical responses of plants to changing conditions during development. Towards the end of her career she began thinking about how environmental signals might influence embryogenesis. Her thoughts about in ovulo responses influenced my recent work. In conifers, external factors can be manipulated to interesting effect during both zygotic and somatic embryogenesis. We have looked at both morphological and physiological variation in vitro. Cotyledons, which are the first lateral organs to form during embryogenesis, normally occur in a whorl of six in Douglas-fir and larch. However, by altering conditions during somatic embryo maturation, cotyledon number can be dramatically altered. This has led to a mathematical understanding of whorl formation. Physiological phenotypic ...
1. Evidence has accumulated that the action of auxins in promoting growth is exerted not upon the cell wall but upon the cell contents; i.e ., the protoplasm. Following indications previously obtained, therefore, the effect of auxins on the rate of protoplasm streaming in the Avena coleoptile was studied. 2. Indole-3-acetic acid, the most active auxin available in pure form, was found to increase the rate of streaming in the epidermal cells of the Avena coleoptile at concentrations between 0.5 and 0.002 mg. per liter, the maximum increase being brought about at 0.01 mg. per liter. This concentration is approximately that which, applied in agar to one side of the decapitated coleoptile, would give a curvature of 1°; i.e ., it is well within the range of concentrations active in growth promotion. It is, however, much less than that which produces maximum elongation in immersed sections of Avena coleoptiles. 3. This accelerating effect is readily determined quantitatively by comparison with the ...

If seeds were to sprout inside an apple, the cotyledons (the first false leaves that develops when the sprout unfolds itself) would not be able to reach the light going through its casing and the thick somewhat hard pulp and the growth process would be chocked.

Nature is a lot smarter. ...
