Cotyledon
A part of the embryo in a seed plant. The number of cotyledons is an important feature in classifying plants. In seeds without an endosperm, they store food which is used in germination. In some plants, they emerge above the soil surface and become the first photosynthetic leaves. (From Concise Dictionary of Biology, 1990)
Seeds
Germination
The initial stages of the growth of SEEDS into a SEEDLINGS. The embryonic shoot (plumule) and embryonic PLANT ROOTS (radicle) emerge and grow upwards and downwards respectively. Food reserves for germination come from endosperm tissue within the seed and/or from the seed leaves (COTYLEDON). (Concise Dictionary of Biology, 1990)
Arabidopsis
Hypocotyl
The region of the stem beneath the stalks of the seed leaves (cotyledons) and directly above the young root of the embryo plant. It grows rapidly in seedlings showing epigeal germination and lifts the cotyledons above the soil surface. In this region (the transition zone) the arrangement of vascular bundles in the root changes to that of the stem. (From Concise Dictionary of Biology, 1990)

Fabaceae
The large family of plants characterized by pods. Some are edible and some cause LATHYRISM or FAVISM and other forms of poisoning. Other species yield useful materials like gums from ACACIA and various LECTINS like PHYTOHEMAGGLUTININS from PHASEOLUS. Many of them harbor NITROGEN FIXATION bacteria on their roots. Many but not all species of "beans" belong to this family.

Placenta
A highly vascularized mammalian fetal-maternal organ and major site of transport of oxygen, nutrients, and fetal waste products. It includes a fetal portion (CHORIONIC VILLI) derived from TROPHOBLASTS and a maternal portion (DECIDUA) derived from the uterine ENDOMETRIUM. The placenta produces an array of steroid, protein and peptide hormones (PLACENTAL HORMONES).

Plants
Multicellular, eukaryotic life forms of kingdom Plantae (sensu lato), comprising the VIRIDIPLANTAE; RHODOPHYTA; and GLAUCOPHYTA; all of which acquired chloroplasts by direct endosymbiosis of CYANOBACTERIA. They are characterized by a mainly photosynthetic mode of nutrition; essentially unlimited growth at localized regions of cell divisions (MERISTEMS); cellulose within cells providing rigidity; the absence of organs of locomotion; absence of nervous and sensory systems; and an alternation of haploid and diploid generations.

Angiosperms
Members of the group of vascular plants which bear flowers. They are differentiated from GYMNOSPERMS by their production of seeds within a closed chamber (OVARY, PLANT). The Angiosperms division is composed of two classes, the monocotyledons (Liliopsida) and dicotyledons (Magnoliopsida). Angiosperms represent approximately 80% of all known living plants.

Gymnosperms
Gymnosperms are a group of vascular plants whose seeds are not enclosed by a ripened ovary (fruit), in contrast to ANGIOSPERMS whose seeds are surrounded by an ovary wall. The seeds of many gymnosperms (literally, "naked seed") are borne in cones and are not visible. Taxonomists now recognize four distinct divisions of extant gymnospermous plants (CONIFEROPHYTA; CYCADOPHYTA; GINKGOPHYTA; and GNETOPHYTA).

Plants, Edible
An organism of the vegetable kingdom suitable by nature for use as a food, especially by human beings. Not all parts of any given plant are edible but all parts of edible plants have been known to figure as raw or cooked food: leaves, roots, tubers, stems, seeds, buds, fruits, and flowers. The most commonly edible parts of plants are FRUIT, usually sweet, fleshy, and succulent. Most edible plants are commonly cultivated for their nutritional value and are referred to as VEGETABLES.

Phytochrome A
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)

Germination14
- The cotyledon, classified as a monocotyledon, or singular, seed leaf developing from the base of the embryo, sits near the three germination pores, commonly called eyes. (ehow.com)
- After germination, the cotyledon forms and goes through several changes. (ehow.com)
- In seeds without an endosperm , e.g. garden pea and broad bean, the cotyledons store food, which is used in germination. (encyclopedia.com)
- in others, such as the bean, the cotyledons store the seed's food reserve for germination and are fleshy. (encyclopedia.com)
- The primary interface between the emerging seedling and its environment is formed by an extra-cuticular endosperm-derived glycoprotein-rich structure called the sheath, which is maintained as a continuous layer at seedling surfaces during germination and becomes fragmented as cotyledons expand. (ens-lyon.fr)
- Although krs mutants have no defects in germination sensu stricto, they show delayed cotyledon emergence, a defect not observed in seedlings with defects in cuticle biosynthesis. (ens-lyon.fr)
- In contrast, krs mutant cotyledons show enhanced adhesion at germination. (ens-lyon.fr)
- We propose that the sheath reduces the adhesiveness of the cotyledon surface under the humid conditions necessary for seed germination and thus promotes seed-coat shedding and rapid seedling establishment. (ens-lyon.fr)

- However, the DNA methylation pattern during Gossypium hirsutum L. cotyledon senescence is poorly understood. (pubmedcentralcanada.ca)
- In this study, global DNA methylation patterns were compared between two cotyledon development stages, young (J1) and senescence (J2), using methylated DNA immunoprecipitation (MeDIP-Seq). (pubmedcentralcanada.ca)
Vigna6
- Mixed micelles of 32 P-labeled phosphatidylcholine or phosphatidic acid (PA) and the nonionic detergent octylphenol polyethylene oxide (NP-40 Nonidet) were used to assay the activities of phospholipase D and PA phosphatase in crude extracts of mung bean ( Vigna radiata ) cotyledons. (plantphysiol.org)
- Arginase was purified from Vigna catjang cotyledons and buffalo liver by chromatographic separations using Bio-Gel P-150, DEAE-cellulose and arginine AH Sepharose 4B affinity columns. (ijbs.com)
- The native molecular weight of an enzyme estimated on Bio-Gel P-300 column for Vigna catjang was 210 kDa and 120 kDa of buffalo liver, while SDS-PAGE showed a single band of molecular weight 52 kDa for cotyledon and 43 kDa for buffalo liver arginase. (ijbs.com)
- The activity of guanidino compounds as alternate substrates for Vigna catjang cotyledon and buffalo liver arginase is critically dependent on the length of the amino acid side chain and the number of carbon atoms. (ijbs.com)
- But no properties of the purified enzyme from the cotyledons of Vigna catjang and buffalo liver have been reported. (ijbs.com)
- Hence the present study was undertaken for the purification and properties of arginase from Vigna catjang cotyledon and buffalo liver, and also reports physicochemical and kinetic properties of the purified enzyme. (ijbs.com)
Cucumber2
Content1
- Growth inhibition was observed, and relative water content in the developing cotyledons significantly decreased in the 100 mM NaCl treatment. (conicyt.cl)
Hypocotyl2
- In laterne mutants, the cotyledons are precisely deleted, yet the hypocotyl and root are unaffected. (biologists.org)
- For example, a pine seedling has from 5 to 20 or so narrow cotyledons forming a whorl at the top of the hypocotyl (the embryonic stem) surrounding the plumule. (academickids.com)
Endosperm1
- The nutrients in the endosperm of dicots is absorbed by the two cotyledons. (stavby-paka.cz)
Grasses1
- The cotyledon of grasses and many other monocotyledons is a highly modified leaf composed of a scutellum and a coleoptile. (wikipedia.org)
Mutants1
- However, analysis of pid enp stm triple mutants shows that ectopic activity of STM does not appear to cause cotyledon obliteration. (biologists.org)
Enzymes2
- The enzymes are present in fully imbibed cotyledons and increase in activity during seedling growth. (plantphysiol.org)
- The effects of treatment with 50 and 100 mM NaCl on cotyledon growth, nitrogen assimilation, and the activities of key nitrogen metabolism enzymes were investigated in developing Jatropha curcas cotyledons. (conicyt.cl)
Growth3
- In this investigation, we have studied the effect of growth conditions (e.g. temperature and light) on the composition of glycerolipid classes and their respective fatty acids during the maturation period of squash cotyledons. (eurekamag.com)
- We have found that the changes in the lipid fatty acid composition of TM which are induced by different temperature and light growth conditions occurred only during the development of cotyledons but not when these latter had reached their maturity. (eurekamag.com)
- Whatever the growth conditions, the level of 16:1(3t) increased during the maturation of cotyledons and was characterized by an increasing linear correlation (r=0.99) with the fresh weight. (eurekamag.com)
Tissues1
- Subsequently, the cotyledons emerge rapidly from the extra-embryonic tissues of the seed, allowing autotrophic seedling establishment [1, 2]. (ens-lyon.fr)
Watson1
- L. cotyledon (S. Watson) B.L. Rob. (berkeley.edu)
Storage organ1
- The latter is typically the case where the cotyledons act as a storage organ, as in many nuts and acorns. (wikipedia.org)
