LEC1 acts as a key regulator of embryogenesis in Arabidopsis thaliana, but is involved in a wide range of functions, all the way from embryo morphogenesis to seed maturation. New data show that LEC1, partially in conjunction with abscisic acid, affects auxin synthesis, and both brassinosteroid and light signaling. The phenotype of LEC1 overexpressors confirms LEC1's known participation in the regulation of somatic embryogenesis, but also indicates additional roles in embryonic and extra-embryonic cell elongation. Here we present an integrated model of LEC1 function and suggest potential directions to be taken in future research in this important area of plant science.
LEC1 在拟南芥胚胎发生中充当关键调控因子,但涉及广泛的功能,从胚胎形态发生到种子成熟。新数据表明,LEC1 与脱落酸部分结合,影响生长素的合成,以及油菜素内酯和光信号。LEC1 过表达体的表型证实了 LEC1 已知参与体细胞胚胎发生的调控,但也表明在胚胎和胚胎外细胞伸长中存在额外的作用。在这里,我们提出了 LEC1 功能的综合模型,并提出了在这一重要植物科学领域未来研究中可能采取的方向。
