Genetic Analysis of S5 Regulating the Hybrid Sterility between Indica and Japonica Subspecies in Rice

Agronomy, 2023
Hybrid sterility is the major obstacle to the utilization of inter-subspecific heterosis in hybrid rice breeding. The S5 locus, composed of three adjacent genes ORF3, ORF4, and ORF5, plays a crucial role in regulating indica/japonica hybrids’ female ...

Resistance of Some Chinese Hybrid Rice, Conventional Early Indica and Late Japonica Rice to Magnaporthe Grisea

, 2004
Thirty isolates of Magnaporthe grisea collected from 18 provinces/cities representing 21 pathotypes and 9 different lineages were inoculated to rice varieties with known resistance genes, some hybrid rice, and conventional early indica and late japonica varieties cultivated in recent years in China.

Natural variation in OsMYB8 confers diurnal floret opening time divergence between indica and japonica subspecies

Nature Communications
The inter-subspecific indica-japonica hybrid rice confer potential higher yield than the widely used indica-indica intra-subspecific hybrid rice. Nevertheless, the utilization of this strong heterosis is currently hindered by asynchronous diurnal floret ...

Preliminary Exploration of Physiology and Genetic Basis Underlying High Yield in Indica–Japonica Hybrid Rice

Agriculture
The utilization of heterosis is of great significance in improving rice yield. To explore the physiological and genetic basis for high yield in indica–japonica hybrid rice, Zheyou18 (z18) and Yongyou12 (y12) were used as materials and compared with ...

Natural variation in the evolutionarily conserved F-box gene SDEF promotes seed dormancy in rice. [PDF]

Plant J
SUMMARY Insufficient seed dormancy causes pre‐harvest sprouting (PHS) and severe yield losses in rice; however, genetic resources with practical breeding value remain limited. Here, we isolated a major dormancy gene, SDEF, via map‐based cloning using chromosomal single segment substitution lines (SSSLs), identifying a functional SNP (Arg‐to‐Trp) as the

Dual Repression by IPA1 Fine-Tunes OsbZIP79-Mediated Salt Tolerance in Rice. [PDF]

Adv Sci (Weinh)
Dual repression by IPA1 fine‐tunes OsbZIP79‐mediated salt tolerance in rice: direct transcriptional inhibition under normal conditions and salt‐induced degradation under stress. This dual mechanism activates OsbZIP79 to regulate Na+/K+ homeostasis and redox balance via downstream genes, enabling optimal salt stress response.
