HUA1 and HUA2 are two members of the floral homeotic AGAMOUS pathway. (1/85)

The identities of the four floral organ types in an Arabidopsis flower are specified by the combinatorial activities of the floral homeotic A, B, and C function genes; AGAMOUS is the only known C function gene. We have identified two genes that interact with AG in the specification of floral structure, HUA1 and HUA2, from a screen for enhancers of a weak ag allele, ag-4. HUA1 and HUA2 are involved in all aspects of AG function. HUA2 encodes a novel protein that contains nuclear localization signals and signature motifs that suggest HUA2, like AG, may be a transcription factor. Molecular analyses suggest that HUA2 (and possibly HUA1) acts to facilitate AG action at the same hierarchical level as AG.  (+info)

CRABS CLAW and SPATULA, two Arabidopsis genes that control carpel development in parallel with AGAMOUS. (2/85)

To help understand the process of carpel morphogenesis, the roles of three carpel development genes have been partitioned genetically. Mutants of CRABS CLAW cause the gynoecium to develop into a wider but shorter structure, and the two carpels are unfused at the apex. Mutants of a second gene, SPATULA, show reduced growth of the style, stigma, and septum, and the transmitting tract is absent. Double mutants of crabs claw and spatula with homeotic mutants that develop ectopic carpels demonstrate that CRABS CLAW and SPATULA are necessary for, and inseparable from, carpel development, and that their action is negatively regulated by A and B organ identity genes. The third carpel gene studied, AGAMOUS, encodes C function that has been proposed to fully specify carpel identity. When AGAMOUS function is removed together with the A class gene APETALA2, however, the organs retain many carpelloid properties, suggesting that other genes are also involved. We show here that further mutant disruption of both CRABS CLAW and SPATULA function removes remaining carpelloid properties, revealing that the three genes together are necessary to generate the mature gynoecium. In particular, AGAMOUS is required to specify the identity of the carpel wall and to promote the stylar outgrowth at the apex, CRABS CLAW suppresses radial growth of the developing gynoecium but promotes its longitudinal growth, and SPATULA supports development of the carpel margins and tissues derived from them. The three genes mostly act independently, although there is genetic evidence that CRABS CLAW enhances AGAMOUS and SPATULA function.  (+info)

The Arabidopsis FILAMENTOUS FLOWER gene is required for flower formation. (3/85)

A screen for mutations affecting flower formation was carried out and several filamentous flower (fil) alleles were identified. In fil mutants, floral primordia occasionally give rise to pedicels lacking flowers at their ends. This defect is dramatically enhanced in fil rev double mutants, in which every floral primordium produces a flowerless pedicel. These data suggest that the FIL and REV genes are required for an early step of flower formation, possibly for the establishment of a flower-forming domain within the floral primordium. The FIL gene is also required for establishment of floral meristem identity and for flower development. During flower development, the FIL gene is required for floral organ formation in terms of the correct numbers and positions; correct spatial activity of the AGAMOUS, APETALA3, PISTILLATA and SUPERMAN genes; and floral organ development.  (+info)

Activation of a floral homeotic gene in Arabidopsis. (4/85)

The patterned expression of floral homeotic genes in Arabidopsis depends on the earlier action of meristem-identity genes such as LEAFY, which encodes a transcription factor that determines whether a meristem will generate flowers instead of leaves and shoots. The LEAFY protein, which is expressed throughout the flower, participates in the activation of homeotic genes, which are expressed in specific regions of the flower. Analysis of a LEAFY-responsive enhancer in the homeotic gene AGAMOUS indicates that direct interaction of LEAFY with this enhancer is required for its activity in plants. Thus, LEAFY is a direct upstream regulator of floral homeotic genes.  (+info)

Non-AUG initiation of AGAMOUS mRNA translation in Arabidopsis thaliana. (5/85)

The MADS box organ identity gene AGAMOUS (AG) controls several steps during Arabidopsis thaliana flower development. AG cDNA contains an open reading frame that lacks an ATG triplet to function as the translation initiation codon, and the actual amino terminus of the AG protein remains uncharacterized. We have considered the possibility that AG translation can be initiated at a non-AUG codon. Two possible non-AUG initiation codons, CUG and ACG, are present in the 5' region of AG mRNA preceding the highly conserved MADS box sequence. We prepared a series of AG genomic constructs in which these codons are mutated and assayed their activity in phenotypic rescue experiments by introducing them as transgenes into ag mutant plants. Alteration of the CTG codon to render it unsuitable for acting as a translation initiation site does not affect complementation of the ag-3 mutation in transgenic plants. However, a similar mutation of the downstream ACG codon prevents the rescue of the ag-3 mutant phenotype. Conversely, if an ATG is introduced immediately 5' to the disrupted ACG codon, the resulting construct fully complements the ag-3 mutation. The AG protein synthesized in vitro by initiating translation at the ACG position is active in DNA binding and is of the same size as the AG protein detected from floral tissues, whereas AG polypeptides with additional amino-terminal residues do not appear to bind DNA. These results indicate that translation of AG is initiated exclusively at an ACG codon and prove that non-AUG triplets may be efficiently used as the sole translation initiation site in some plant cellular mRNAs.  (+info)

Redundant enhancers mediate transcriptional repression of AGAMOUS by APETALA2. (6/85)

The floral homeotic gene AGAMOUS specifies stamen and carpel fate in the central whorls of Arabidopsis flowers. Transcription of AGAMOUS RNA is restricted to the center of developing flowers by several, partially redundant negative regulators, one of which is the homeotic gene APETALA2. We have identified regulatory elements that mediate transcriptional repression of AGAMOUS by APETALA2 and found that several redundant elements respond independently to loss of APETALA2 activity. Thus, redundancy at the level of cis-regulatory sequences is independent of redundancy at the level of trans-regulators. We have also found that only the early, but not the late, effects of APETALA2 on AGAMOUS require the meristem-identity protein LEAFY, a positive regulator of AGAMOUS.  (+info)

Ectopic hypermethylation of flower-specific genes in Arabidopsis. (7/85)

BACKGROUND: Arabidopsis mutations causing genome-wide hypomethylation are viable but display a number of specific developmental abnormalities, including some that resemble known floral homeotic mutations. We previously showed that one of the developmental abnormalities present in an antisense-METHYLTRANSFERASEI (METI) transgenic line resulted from ectopic hypermethylation of the SUPERMAN gene. RESULTS: Here, we investigate the extent to which hypermethylation of SUPERMAN occurs in several hypomethylation mutants, and describe methylation effects at a second gene, AGAMOUS. SUPERMAN gene hypermethylation occurred at a high frequency in several mutants that cause overall decreases in genomic DNA methylation. The hypermethylation pattern was largely similar in the different mutant backgrounds. Genetic analysis suggests that hypermethylation most likely arose either during meiosis or somatically in small sectors of the plant. A second floral development gene, AGAMOUS, also became hypermethylated and silenced in an Arabidopsis antisense-METI line. CONCLUSIONS: These results suggest that ectopic hypermethylation of specific genes in mutant backgrounds that show overall decreases in methylation may be a widespread phenomenon that could explain many of the developmental defects seen in Arabidopsis methylation mutants. This resembles a phenomenon seen in cancer cells, which can simultaneously show genome-wide hypomethylation and hypermethylation of specific genes. Comparison of the methylated sequences in SUPERMAN and AGAMOUS suggests that hypermethylation could involve DNA secondary structures formed by pyrimidine-rich sequences.  (+info)

Specific and heritable genetic interference by double-stranded RNA in Arabidopsis thaliana. (8/85)

We investigated the potential of double-stranded RNA interference (RNAi) with gene activity in Arabidopsis thaliana. To construct transformation vectors that produce RNAs capable of duplex formation, gene-specific sequences in the sense and antisense orientations were linked and placed under the control of a strong viral promoter. When introduced into the genome of A. thaliana by Agrobacterium-mediated transformation, double-stranded RNA-expressing constructs corresponding to four genes, AGAMOUS (AG), CLAVATA3, APETALA1, and PERIANTHIA, caused specific and heritable genetic interference. The severity of phenotypes varied between transgenic lines. In situ hybridization revealed a correlation between a declining AG mRNA accumulation and increasingly severe phenotypes in AG (RNAi) mutants, suggesting that endogenous mRNA is the target of double-stranded RNA-mediated genetic interference. The ability to generate stably heritable RNAi and the resultant specific phenotypes allows us to selectively reduce gene function in A. thaliana.  (+info)

We describe a locus, SUPERMAN, mutations in which result in extra stamens developing at the expense of the central carpels in the Arabidopsis thaliana flower. The development of superman flowers, from initial primordium to mature flower, is described by scanning electron microscopy. The development of doubly and triply mutant strains, constructed with superman alleles and previously identified homeotic mutations that cause alterations in floral organ identity, is also described. Essentially additive phenotypes are observed in superman agamous and superman apetala2 double mutants. The epistatic relationships observed between either apetala3 or pistillata and superman alleles suggest that the SUPERMAN gene product could be a regulator of these floral homeotic genes. To test this, the expression patterns of AGAMOUS and APETALA3 were examined in superman flowers. In wild-type flowers, APETALA3 expression is restricted to the second and third whorls where it is required for the specification of ...
Tightly balanced antagonism between the Polycomb group (PcG) and the Trithorax group (TrxG) complexes maintain Hox expression patterns in Drosophila and murine model systems. Factors belonging to the PcG/TrxG complexes control various processes in plants as well but whether they participate in mechanisms that antagonize, balance or maintain each others effects at a particular gene locus is unknown. CURLY LEAF (CLF), an Arabidopsis homolog of enhancer of zeste (EZ) and the ARABIDOPSIS HOMOLOG OF TRITHORAX (ATX1) control the expression of the flower homeotic gene AGAMOUS (AG). Disrupted ATX1 or CLF function results in misexpression of AG, recognizable phenotypes and loss of H3K4me3 or H3K27me3 histone H3-tail marks, respectively. A novel idea suggested by our results here, is that PcG and TrxG complexes function as a specific pair generating bivalent chromatin marks at the silent AG locus. Simultaneous loss of ATX1 and CLF restored AG repression and normalized leaf phenotypes. At the molecular level,

Looking for online definition of agamous in the Medical Dictionary? agamous explanation free. What is agamous? Meaning of agamous medical term. What does agamous mean?
Peptide nucleic acids (PNAs) are polyamide oligomers that can strand invade duplex DNA, causing displacement of one DNA strand and formation of a D-loop. Binding of either a T10 PNA or a mixed sequence 15-mer PNA to the transcribed strand of a G-free transcription cassette caused 90 to 100 percent site-specific termination of pol II transcription elongation. When a T10 PNA was bound on the nontranscribed strand, site-specific inhibition never exceeded 50 percent. Binding of PNAs to RNA resulted in site-specific termination of both reverse transcription and in vitro translation, precisely at the position of the PNA.RNA heteroduplex. Nuclear microinjection of cells constitutively expressing SV40 large T antigen (T Ag) with either a 15-mer or 20-mer PNA targeted to the T Ag messenger RNA suppressed T Ag expression. This effect was specific in that there was no reduction in beta-galactosidase expression from a coinjected expression vector and no inhibition of T Ag expression after microinjection of ...

Author(s): Kim, YunJu | Advisor(s): Chen, Xuemei | Abstract: Forward genetics is a powerful tool to identify genes involved in particular biological processes. In my thesis work, I participated in forward genetic screens to identify genes involved in two biological processes in plants, stem cell maintenance in the floral meristem and small RNA biogenesis/function. First, I characterized a Polycomb (PcG) gene, CURLY LEAF (CLF) as a factor required for floral meristem termination. A mutation in CLF enhances the floral determinacy defects of ag-10, a weak allele in AGAMOUS (AG), a gene essential for floral stem cell termination. CLF acts in the AG pathway to repress the stem cell identity gene, WUSCHEL (WUS) to result in floral stem cell termination. In addition, I show that this role of CLF reflects the role of the PcG complex in the control of floral meristem determinacy. Taken together, I provide a link between epigenetic regulation and stem cell maintenance in the floral meristem. Second, I identified

Arabidopsis plants undergo a transition from vegetative growth, in which the shoot apical meristem produces leaves and axillary buds, to reproductive growth, when the meristem begins to form flowers. The meristem identity genes LEAFY (LFY) and APETALA1 (AP1) are both necessary and sufficient for this transition to reproductive growth and the concomitant formation of flowers. Loss of LFY function leads to leaves and shoots in place of flowers, while constitutive expression of LFY results in precocious floral development (Weigel et al., 1992; Weigel and Nilsson, 1995). Similarly, constitutive AP1 expression also results in premature flowering, and loss of AP1 function results in a partial transformation of flowers to more inflorescence-like structures (Bowman et al., 1993; Irish and Sussex, 1990; Mandel and Yanofsky, 1995).. In turn, the development of floral structures depends on the action of three classes of floral homeotic genes, A, B and C. These ABC floral homeotic genes function in ...
In plants, genome duplication followed by genome diversification and selection is recognized as a major evolutionary process. Rapid epigenetic and genetic changes that affect the transcription of parental genes are frequently observed after polyploidization. The pattern of alternative splicing is also frequently altered, yet the related molecular processes remain largely unresolved. Here, we study the inheritance and expression of parental variants of three floral organ identity genes in allotetraploid tobacco. DEFICIENS and GLOBOSA are B-class genes, and AGAMOUS is a C-class gene. Parental variants of these genes were found to be maintained in the tobacco genome, and the respective mRNAs were present in flower buds in comparable amounts. However, among five tobacco cultivars, we identified two in which the majority of paternal GLOBOSA pre-mRNA transcripts undergo exon 3 skipping, producing an mRNA with a premature termination codon. At the DNA level, we identified a G-A transition at the very ...
In determining the best jar spatula to get the last bits to buy, we explored ergonomics (e.g. long narrow, curved head), material/construction, handle, and safety (BPA-free, etc.).. Our favorite criteria for recommending jar spatulas to get the last bits is ergonomics. Preferably, they have long narrow stiffer handles with pointed spatulas that offer a bit of flex to better scrape every last bit of food. Spatula heads are shaped in many ways, primarily pointed, rounded, and squarish. Our preference is for stiffer, pointed spatulas for heavier work and more flexible, rounded tip spatulas for lighter duty.. Materials and construction are very important. Our recommendation is to go with flexible silicone. It is very tough, stain, and scratch-resistant with a high heat resistance as high as 650°F which makes it work for dishwasher runs and handling heated food.. Lastly, we factored in safety. Look for food-grade silicone kitchen tools that are BPA free. BPA is a common chemical additive found in ...
