A wheat phytohormone atlas spanning major tissues across the entire life cycle provides novel insights into cytokinin and jasmonic acid interplay.

Although numerous studies have focused on the specific organs or tissues at different development stages or under various abiotic and biotic stress, our understanding of the distribution and relative abundance of phytohormones throughout the entire life cycle of plant organs and tissues remains insufficient. Here, we present a phytohormone atlas resource covering the quantitative analysis of eight major classes of phytohormones, comprising a total of 40 hormone-related compounds, throughout the complete life cycle of wheat. In combination with transcriptome analysis, we established a Wheat Phytohormone Metabolic Regulatory Network (WPMRN).

Deciphering genetic basis of developmental and agronomic traits by integrating high-throughput optical phenotyping and genome-wide association studies in wheat.

Dissecting the genetic basis of complex traits such as dynamic growth and yield potential is a major challenge in crops. Monitoring the growth throughout growing season in a large wheat population to uncover the temporal genetic controls for plant growth and yield-related traits has so far not been explored. In this study, a diverse wheat panel composed of 288 lines was monitored by a non-invasive and high-throughput phenotyping platform to collect growth traits from seedling to grain filling stage and their relationship with yield-related traits was further explored.

Short-term waterlogging-induced autophagy in root cells of wheat can inhibit programmed cell death.

Autophagy is a pathway for the degradation of cytoplasmic components in eukaryotes. In wheat, the mechanism by which autophagy regulates programmed cell death (PCD) is unknown. Here, we demonstrated that short-term waterlogging-induced autophagy inhibited PCD in root cells of wheat.
