Cereals are grown in almost every region of the world and are exposed to a variety of
environmental stresses that severely affect their growth and grain yield. Of various abiotic …

Crop domestication is the process of artificially selecting plants to increase their suitability to
human requirements: taste, yield, storage, and cultivation practices. There is increasing …

The origin of domesticated Asian rice (Oryza sativa L.) has been controversial for more than
half a century. The debates have focused on two leading hypotheses: a single domestication …

Rice is sensitive to cold and can be grown only in certain climate zones. Human selection of
japonica rice has extended its growth zone to regions with lower temperature, while the …

Crop domestications are long-term selection experiments that have greatly advanced
human civilization. The domestication of cultivated rice (Oryza sativa L.) ranks as one of the …

The indica and japonica rice (Oryza sativa) subspecies differ in nitrate (NO3−) assimilation
capacity and nitrogen (N) use efficiency (NUE). Here, we show that a major component of …

As an essential macroelement for all living cells, phosphorus is indispensable in agricultural
production systems. Natural phosphorus reserves are limited, and it is therefore important to …

Background At present, plant molecular systematics and DNA barcoding techniques rely
heavily on the use of chloroplast gene sequences. Because of the relatively low evolutionary …

Rice is a staple crop that has undergone substantial phenotypic and physiological changes
during domestication. Here we resequenced the genomes of 40 cultivated accessions …

How two subgenomes in allo-tetraploids adapt to coexistence and coordinate through
structure and expression evolution requires extensive studies. In the present study, we …
