A walk on the wild side: Oryza species as source for rice abiotic stress tolerance.

摘要: Oryza sativa, the common cultivated rice, is one of most important crops for human consumption, but production increasingly threatened by abiotic stresses. Although many efforts have resulted in breeding rice cultivars that are relatively tolerant to their local environments, climate changes and population increase expected soon call new, fast generation stress germplasm, current within-species diversity might not be enough overcome such needs. The genus contains other 23 wild species, with only glaberrima being also domesticated. Rice domestication was performed a narrow genetic diversity, species virtually untapped resource tolerance improvement. Here we review origin domesticated sativa from progenitors, ecological genomic genus, variation observed including basis underlying mechanisms found. summary provided here indicate how should move forward unlock full potential these germplasms
