Project description:By performing QTL mapping using 82 backcross inbred lines (BILs) of the Koshihikari (japonica) and Habataki (indica) cultivars for the rice initial growth, we identified two QTLs, qEPD1 and qEPD2, responsible for modulating plant height and/or leaf sheath length. To narrow down the number of candidate genes of each QTL, we conducted transcriptional profiling using RNAs isolated from the vegetative stem of Koshihikari and its two substituted lines (SL) with the Habataki qEPD1 or qEPD2 allele.

Oryza sativa cultivar:Nippobare Transcriptome or Gene expression

Project description:We used RNA-Seq to systematically investigate the global transcriptomes of rice which was inoculated with viruliferous SBPH, or inoculated with insect-derived RSV or plant-derived RSV by mechanical inoculation, and generated a useful resource for the immune reaction of rice in face of different kinds of RSV. The changes in the expression of candidate transcripts may provide valuable information for future studies on molecular mechanisms of rice stripe disease.

Oryza sativa cultivar:Nipponbare Transcriptome or Gene expression

Project description:A comprehensive time-course experiment of Pi-starved plants was undertaken, spanning medium (3 and 7 days), and long-term (21 days up to 52 days) Pi deprivation (âPi), as well as both short term (1 and 3 days) and long-term (31 days) recovery. The 52 days time point consisting of 21 days starvation +31 days recovery enabled investigation of the effects of long term resupply on Pi starved plants, and coincided with the emergence of the first panicles and grains. Pre-germinated rice seedlings were grown for 14 days in Pi sufficient conditions (0.32 mM Pi) before being transferred to either Pi sufficient (0.32 mM Pi) or Pi deficient (0 mM Pi) media for 21 days. After 21 days of Pi deficient treatment, half of the plants were either maintained under Pi deficient conditions or re-supplied with Pi (0.32 mM) for 1, 3 or 31 days. To confirm the effectiveness of the Pi starvation and resupply treatments, physiological and molecular analyses were performed.
