A seed consists of an embryo, endosperm, and seed coat. Here the authors show that autophagy plays a crucial role in regulating timely programmed cell death in the innermost seed coat, thereby influencing embryo pattern formation and seed viability.

An efficient method of cyto-swapping by haploid induction using a CENH3 mutation is reported in maize, to convert commercial germplasm to cytoplasmic male sterility for hybrid seed production.

HvMADS1 in barley positively regulates awn length and lemma width by promoting cell proliferation through direct action on the expression of HvSHI and HvDL. In wheat, MADS1 conservatively regulates awn length.

Maize kernels have long intrigued researchers due to their complex structure. Through microscopic sectioning and spatial transcriptomics, the authors observed the spatial distribution of RNA through electronic RNA in situ hybridization maps and discovered how storage accumulation occurs.

Sustainable crop protection approaches are crucial to feeding an exponentially increasing global population. Seed wraps developed from banana harvest biomass and loaded with an ultra-low volume of a pesticide resulted in a substantial increase in the yield and quality of yam crops in field trials in Benin.
