Seed maturation
WebElevated temperature during early seed development can decrease seed size, number, and fertility, delay germination and reduce seed vigor in crops such as cereals, legumes, and … WebMar 9, 2024 · Seed development consists of two major processes, embryonic morphogenesis, and seed maturation. We analyzed bli-1 embryos from the early globular to the torpedo stage and identified no obvious difference between bli-1 and WT embryos ( Supplemental Figure S4 ). We also characterized the seed maturation stages of bli-1.

WebJul 24, 2024 · Seed development is biphasic, consisting of the morphogenesis phase when the basic plant body plan is established and the maturation phase when the embryo accumulates storage reserves and becomes desiccation tolerant. Despite the importance of seeds as human food and animal feed, little is known about the gene-regulatory networks … WebAug 28, 2024 · Seed longevity, the maintenance of viability during dry storage, is a crucial factor to preserve plant genetic resources and seed vigor. Inference of a temporal gene-regulatory network of seed maturation identified auxin signaling as a putative mechanism to induce longevity-related genes.
Seed maturation is a key period in a plant's lifecycle allowing for distribution of offspring in space and time. Events occurring during maturation include storage reserve deposition, desiccation, dormancy induction, seed coat formation, and protective compound synthesis.
