mRNA Decay Mediates Evolution and Biological Functions in Plant Gene Expression

Plant Biotechnology Journal, EarlyView.
ABSTRACT mRNA decay is a key post‐transcriptional regulatory mechanism that fine‐tunes plant development and stress adaptation through dynamic mRNA stability control, bridging fundamental biology and crop improvement. Current knowledge of mRNA decay mechanisms in plants, largely derived from Arabidopsis, is poorly generalisable across plant lineages ...

Screening for Fall Armyworm (Spodoptera frugiperda J. E. Smith) Resistance in Early‐Maturing Tropical Maize Adapted to Sub‐Saharan Africa

Plant Breeding, EarlyView.
ABSTRACT Fall armyworm (FAW) (Spodoptera frugiperda J. E. Smith) has emerged as a serious pest since 2016 in Africa, affecting the food security and livelihoods of millions of smallholder farmers, especially those growing maize. Native genetic resistance to FAW is essential for reducing yield loss.

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.

Avaliação da germinação e dormência de sementes de arroz vermelho e branco

Revista de Ciências Agroveterinárias, 2014
As sementes de arroz branco possuem dormência, porém de intensidade menor que as de arroz vermelho. Entretanto, já foram observados alguns genótipos de arroz vermelho com dormência de intensidade semelhante à de sementes de arroz branco.

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 ...
