Frontiers | LEAFY COTYLEDONs: Connecting different stages of …
网页2022年8月30日 · LEAFY COTYLEDON (LEC) transcription factors, first discovered in Arabidopsis thaliana several decades ago, play a key role in regulating plant embryonic development, seed maturation, and subsequent growth.
LEAFY COTYLEDON1 expression in the endosperm enables …
网页2021年6月25日 · LEC1 expression has been detected not only in the embryo but also in the endosperm in several plant species, including Arabidopsis thaliana 13, Brassica napus 14, and soybean 10, leading to ...
Cell division and cell expansion in cotyledons of Arabidopsis seedlings ...
网页2004年3月11日 · Light-stimulated cotyledon expansion in Arabidopsis seedlings was demonstrated (Neff & Van Volkenburgh, 1994); it has been suggested that there are cell divisions in the cotyledons during the first 10 days of light development of a wild-type plant (Fridlender et al., 1996), or at its third day in the light (Tsukaya et al., 1994).
Arabidopsis CUP-SHAPED COTYLEDON3 regulates …
网页In Arabidopsis thaliana, redundant functions of the CUP-SHAPED COTYLEDON genes CUC1, CUC2, and CUC3 regulate embryonic shoot meristem formation and cotyledon boundary specification. Their functional importance and relationship in postembryonic development, however, is poorly understood.
Cooperative transcriptional regulation by ATAF1 and HY5 ... - Science
网页2024年1月2日 · Exposure of Arabidopsis seedlings to far-red light stimulated phytochrome A and the transcription factor HY5 to induce expression of the transcription factor ATAF1. Cooperation of ATAF1 and HY5 repressed the expression of genes that promote seedling elongation and maintain cotyledon closure.
LEAFY COTYLEDON1 is a key regulator of fatty acid biosynthesis …
网页Here, we show that overexpression of the Arabidopsis (Arabidopsis thaliana) LEAFY COTYLEDON1 (LEC1) gene causes globally increased expression of fatty acid biosynthetic genes, which are involved in key reactions of condensation, chain elongation, and desaturation of fatty acid biosynthesis.
Leafy Cotyledon Mutants of Arabidopsis - PubMed
网页We have previously described a homeotic leafy cotyledon (lec) mutant of Arabidopsis that exhibits striking defects in embryonic maturation and produces viviparous embryos with cotyledons that are partially transformed into leaves. In this study, we present further details on the developmental anatom …
Cotyledons contribute to plant growth and hybrid vigor in Arabidopsis
网页2018年12月14日 · We found Arabidopsis cotyledons are essential for plant growth and in some hybrids for hybrid vigor. In hybrids between C24 and Landsberg erecta (L er), biomass vigor (heterosis) occurs in the first few days after sowing (DAS), with hybrid cotyledons being larger than those of their parents.
Role of Arabidopsis LEAFY COTYLEDON genes in seed …
网页2001年1月1日 · Arabidopsis LEAFY COTYLEDON genes are central regulators of embryogenesis that play key roles in processes that occur during both the early and late phases. Evidence is discussed which suggests that the LEAFY COTYLEDON genes coordinate the morphogenesis and maturation phases and confer embryogenic competence to …
Increasing ambient temperature progressively disassembles Arabidopsis …
网页2020年4月3日 · Here we report temperature-dependent photobody localization of fluorescent protein-tagged phyB (phyB-FP) in the epidermal cells of Arabidopsis hypocotyl and cotyledon. Our results demonstrate...
