Two roads to a full ear: How maize domestication shaped form and function

Journal of Integrative Plant Biology, EarlyView.
Early farmers turned bushy teosinte into maize by two genetic routes: one route reshaped the plant's architecture, and a newly identified route changed its physiology, sending more sugar and nitrogen to the ear. Both increased the share of the plant that becomes grain, and both can guide future crop improvement.

Associations Between Benzoxazinoids, Plant Development and Nutritional Parameters in Different Maize Maturing Genotypes

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Maize (Zea mays L.) silage is a major energy source in ruminant diets and provides fermentable substrate for the rumen microbiota. In addition, forage maize contains benzoxazinoids (BXs), defence‐related secondary metabolites with antimicrobial activity that remain detectable after ensiling.

The rps15-rpl32 intergenic locus is a phylogeographic marker for Latin American Zea mays landrace varieties and subspecies

BMC Genomics
Background Maize (Zea mays L.) has a deep cultural significance in Latin America, with traditional and native varieties cultivated for millennia. Approximately 220 maize races have been identified in the region.

Rice bZIP11 acts as a transcriptional repressor that negatively regulates photosynthesis in response to nitrogen deficiency

New Phytologist, EarlyView.
Phenotypes of 43‐d‐old wild‐type (WT), Osbzip11‐KO, and OsbZIP11‐OX seedlings grown under control N and low N conditions. Summary Nitrogen (N)‐deficiency responses, which are closely linked to plant biomass and crop yield, differ between plant tissues.

Identification of auxin response factor ARF27 as a regulator of maize root morphogenesis

New Phytologist, EarlyView.
Working model for Zea mays ARF27 mediated primary root growth in maize Summary Auxin is a central phytohormone that mediates root development. This study investigated the genetic basis of auxin‐mediated primary root growth in Zea mays (maize) seedlings, which is not well‐understood in this key cereal crop.

A Heat‐Inducible Rubisco Activase Safeguards Photosynthesis via Multilevel Regulation and Dual Function

Plant Biotechnology Journal, EarlyView.
ABSTRACT Rubisco activase (RCA) is critical for maintaining photosynthetic efficiency under heat stress, yet its regulatory mechanisms and functional diversification remain poorly understood. Here, we characterize a novel heat‐inducible RCA family member (RCA1), which plays a pivotal role in mediating multidimensional thermotolerance in a tropical ...

Spatiotemporal Transcriptomics Reveals That a ZF‐HD–GmCWINV4 Module Controls Carbon Partitioning and Seed Size in Soybean

Plant Biotechnology Journal, EarlyView.
ABSTRACT Seed size and oil content are key determinants of agronomic productivity in soybean (Glycine max). Although the ultrastructure and cellular composition of soybean seeds have been well characterised, the spatiotemporal expression patterns of genes governing sucrose transport and catabolism across distinct cell types remain poorly understood ...

A Repertoire of Major Genes From Crop Wild Relatives for Breeding Disease‐Resistant Wheat, Rice, Maize, Soybean and Cotton Crops

Plant Breeding, EarlyView.
ABSTRACT Global food demand is predicted to rise anywhere from 59% to 98% by 2050 because of increasing population. However, the continued depletion of natural resources and increasing biotic and abiotic stresses will continue to pose significant threats to global food security in coming years.

A Century of Understanding and Harnessing Heterosis

Plant Breeding, EarlyView.
ABSTRACT Heterosis has shaped modern plant breeding since Darwin's 19th century observations that outcrossing restores vigour lost through selfing. While 100 years old, its mechanistic basis and deployability remain actively debated. Classical models of dominance, overdominance and epistasis provided the foundation for hybrid breeding and converted ...
