Ovule identity mediated by pre-mRNA processing in Arabidopsis
Ovules are fundamental for plant reproduction and crop yield as they are the precursors of seeds. Therefore, ovule specification is a critical developmental program. In Arabidopsis thaliana, ovule identity is redundantly conferred by the homeotic D-class genes SHATTERPROOF1 (SHP1), SHP2 and SEEDSTICK (STK), phylogenetically related to the MADS-domain regulatory gene AGAMOUS (AG), essential in f...
متن کاملBELL1 and AGAMOUS genes promote ovule identity in Arabidopsis thaliana.
Molecular and genetic analyses have demonstrated that the Arabidopsis thaliana gene BELL1 (BEL1) is required for proper morphogenesis of the ovule integuments. Several lines of evidence suggest that BEL1 may act, at least in part, to repress the function of the organ identity gene AGAMOUS (AG) during ovule development. To study the relative roles of BEL1 and AG, plants homozygous for ag, bel1 o...
متن کاملAutoregulation of FCA pre-mRNA processing controls Arabidopsis flowering time.
The timing of the transition to flowering is critical for reproductive success in plants. Arabidopsis FCA encodes an RNA-binding protein that promotes flowering. FCA expression is regulated through alternative processing of its pre-mRNA. We demonstrate here that FCA negatively regulates its own expression by ultimately promoting cleavage and polyadenylation within intron 3. This causes the prod...
متن کاملOvule abortion in Arabidopsis triggered by stress.
Environmental stresses frequently decrease plant fertility. In Arabidopsis, the effect of salt stress on reproduction was examined using plants grown in hydroponic medium. Salt stress inhibited microsporogenesis and stamen filament elongation. Because plants grown in hydroponic media can be rapidly and transiently stressed, the minimum inductive treatment to cause ovule abortion could be determ...
متن کاملRegulation of pre-mRNA processing by src
BACKGROUND Changes in gene expression in response to external signals provide a key mechanisms for the regulation of higher eukaryotic cell functions. The importance of transcriptional control in the response of cells to growth factors and cytokines has been extensively documented, but gene expression has also been shown to be controlled at other levels, such as the stability of mRNA in the cyt...
