TL;DR: It is demonstrated that alteration of root system architecture improves drought avoidance through the cloning and characterization of DEEPER ROOTING 1 (DRO1), a rice quantitative trait locus controlling root growth angle.

TL;DR: Using this new system, transgenic rice plantlets are successfully regenerated within a month of the start of the aseptic culture of mature seeds and the competency of scutellum tissue from 1-day pre-cultured seeds for Agrobacterium-mediated transformation is reported.

TL;DR: A rice quantitative trait locus, Sdr4, which contributes substantially to differences in seed dormancy between japonica (Nipponbare) and indica (Kasalath) cultivars is cloned, suggesting that Sdr 4 acts as an intermediate regulator of dormancy in the seed maturation program.

TL;DR: The results suggest that the members of this gene family play important roles in the compartmentalization into vacuoles of the Na+ and K+ that accumulate in the cytoplasm and that the differential regulation of antiporter gene expression in different rice tissues may be an important factor determining salt tolerance in rice.

TL;DR: It is demonstrated that a shallower root growth angle (RGA) could enhance rice yields in saline paddies and suggest that DRO1 homologs are valuable targets for RSA breeding and could lead to improved rice production in environments characterized by abiotic stress.
