Aa TFL1 confers an age-dependent response to vernalization in perennial Arabis alpina.
Flowering of many plants is induced by environmental signals, but these responses can depend on the age of the plant. Exposure of Arabidopsis thaliana to vernalization (winter temperatures) at germination induces flowering, whereas a close perennial relative Arabis alpina only responds if exposed when at least 5 weeks old. We show that vernalization of these older A. alpina plants reduces expre...
متن کاملGrainyhead-like 2 downstream targets act to suppress epithelial-to-mesenchymal transition during neural tube closure.
The transcription factor grainyhead-like 2 (GRHL2) is expressed in non-neural ectoderm (NNE) and Grhl2 loss results in fully penetrant cranial neural tube defects (NTDs) in mice. GRHL2 activates expression of several epithelial genes; however, additional molecular targets and functional processes regulated by GRHL2 in the NNE remain to be determined, as well as the underlying cause of the NTDs ...

متن کاملAn alpha-crystallin gene, ACD31.2 from Arabidopsis is negatively regulated by FPF1 overexpression, floral induction, gibberellins, and long days.
A gene sequence was isolated from a differential display experiment to find transcripts altered in expression by overexpression of FLORAL PROMOTING FACTOR 1 (FPF1) in Arabidopsis thaliana. The gene, ACD31.2, encodes an alpha-crystallin domain containing protein with homology to small heat shock proteins. In addition to down-regulation by FPF1 overexpression, the ACD31.2 transcript is also down-...
متن کاملGenetic Regulation of GA Metabolism during Vernalization, Floral Bud Initiation and Development in Pak Choi (Brassica rapa ssp. chinensis Makino)
Pak choi (Brassica rapa ssp. chinensis Makino) is a representative seed vernalization vegetable and premature bolting in spring can cause significant economic loss. Thus, it is critical to elucidate the mechanism of molecular regulation of vernalization and floral bud initiation to prevent premature bolting. Gibberellin (GA) is the key plant hormone involved in regulating plant development. To ...
