Abstract The rice orthologue of maize domestication gene Teosinte branched 1 ( Tb1 ) affects tillering. But, unlike gene, it was not selected during domestication. Here, we report that an OsTb1 duplicate OsTb2 has been artificially upland adaptation and natural variation in is associated with tiller number. Interestingly, transgenic overexpressing this shows increased rather than decreased tillering, suggesting gains a regulatory effect opposite to following duplication. Functional analyses...
Upland rice shows dryland adaptation in the form of a deeper and denser root system greater drought resistance than its counterpart, irrigated rice. Our previous study revealed difference frequency OsNCED2 gene between upland populations. A nonsynonymous mutation (C to T, from rice) may have led functional variation fixed by artificial selection, but exact biological function is unclear. In this study, transgenic association analysis indicated that domesticated caused OsNCED2, increasing ABA...
ABSTRACT There are two ecotypes, upland rice and irrigate rice, during its evolution in rice. Upland exhibits aerobic adaptive phenotype via stronger root system more rapid drought responses compared with counterpart, irrigated We assessed the functional variation applications of allele OsNCED2 T cloned from IRAT104 which is a cultivar -overexpressing transgenic -NILs exhibited significantly higher ABA contents at seedling reproductive stages, can improve development (RD) tolerance (DT) to...
The genetic control of plant architecture in crops is critical for agriculture and understanding morphological evolution. This study showed that an open reading frame (ORF) the rice domestication gene PROG1 appeared 3.4-3.9 million years ago (Mya). Subsequently, it acquired a novel protein-coding function genome O. rufipogon (~0.3-0.4 Mya). extremely young its paralogous C2H2 genes located nearby define prostrate and, thus, are adaptive significance wild swamp water areas. However, selection...
