摘要
在开裂果实植物生命周期的末期,颖果的开裂过程对于种子的正常散播至关重要。目前的研究重点是通过遗传操作来减轻这一过程,提高作物的耐碎性,这对经济有重大影响。在本研究中,我们对拟南芥和十字花科植物中密切相关的三角梅(Brassica juncea、Brassica carinata、Brassica napus、Brassica rapa 和 Brassica nigra)瓣膜组织的细胞形态和发育进行了时程分析。我们的目标是破译瓣膜内果皮 a 细胞层和 b 细胞层的详细时间发育模式,特别是它们的降解和木质化。此外,我们还为内果皮 a 细胞层的木质化提出了一个新的分类系统:L1 表示最靠近假隔膜的细胞,L2 和 L3 分别表示第二和第三细胞,每个数字增量表示离假隔膜更远的木质化细胞。我们的研究结果提供了一个目前文献中缺乏的基础框架,可作为未来基因组学工作的有效蓝图,旨在改变瓣膜结构以提高农艺性状,如减少纤维(木质素)或提高耐破碎性。
Characterizing the role of endocarp a and b cells layers during pod (silique) development in Brassicaceae.
The process of silique dehiscence is essential for the proper dispersal of seeds at the end of a dehiscent fruit plants lifecycle. Current research focuses on genetic manipulation to mitigate this process and enhance shatter tolerance in crop plants, which has significant economic implications. In this study, we have conducted a time-course analysis of cell patterning and development in valve tissues of Arabidopsis thaliana and closely related Triangle of U species (Brassica juncea, Brassica carinata, Brassica napus, Brassica rapa, and Brassica nigra) from Brassicaceae. The goal was to decipher the detailed temporal developmental patterns of the endocarp a and b cell layers of the valve, specifically their degradation and lignification respectively. Additionally, we propose a new classification system for the lignification of the endocarp a cell layer: L1 indicates the cell closest to the replum, with L2 and L3 representing the second and third cells, respectively, each numerical increment indicating lignified cells farther from the replum. Our findings provide a foundational framework absent in current literature, serving as an effective blueprint for future genomic work aimed at modifying valve structures to enhance agronomic traits, such as reducing fiber (lignin) or increasing shatter tolerance.
