This project aims to investigate how developing central cell epitranscriptomes are linked to seed growth, how the cell regulates the unique epigenetic states, and the role of the system in driving phenotypic diversity. Maternal and paternal effects determine growth and development of multicellular angiosperm plants. Previous work has discovered unique ribonucleic acid (RNA) epitranscriptome states dependent on the parent-of-origin in developing central cell that gives rise to the endosperm tissue of the seed that impacts on growth of the seed. This project expects to provide economic benefits by increasing yield of agricultural crops during increasingly challenging conditions.

该项目旨在研究发育中的中央细胞epitranscriptomes如何与种子生长相关联，细胞如何调节独特的表观遗传状态，以及系统在驱动表型多样性中的作用。多细胞被子植物的生长发育受母本和父本作用的影响。先前的工作已经发现了独特的核糖核酸（RNA）表转录组状态，其依赖于发育中的中央细胞中的起源亲本，所述中央细胞产生影响种子生长的种子胚乳组织。该项目预计将通过在日益严峻的条件下提高农作物产量来提供经济效益。
