Bakanae disease is an important fungal disease caused by Gibberella fujikuroi. The outbreak of rice bakanae disease causes the most important problems for rice producing countries and affects almost all known rice cultivars. Identifying balance disease resistance in Korean Rice Landrace with diverse genetic sources is important for efficient breeding. In this study, we tried to find out useful genetic resources for bakanae resistant cultivar. The result suggested highly strong 3 varieties (‘IT010631’, ‘IT009118’ and ‘IT009221’.) to be used in breeding program. Additionally, we applied reported marker related qFfR1 bakanae disease to accessions which showed strong resistance. It is expected that these resources can be used to develop useful cultivars for each trait. Especially, accessions showed strong resistance in this study have different genotype with reported resistant resources, they would be used to find other genes related to bakanae resistance.

Tiller development is an important agronomic trait in plant architecture and grain yield. Many plant hormones regulate axillary meristem formation, including bud outgrowth for shoot branching. However, the molecular mechanism underlying the brassinosteroid (BR) in tiller development is not yet well known. Therefore, in this study, we identified and characterized two novel T-DNA insertion mutants, osgras19 and osgras32, which showed the typical BR-deficient phenotype, such as fewer tiller numbers, dark-green leaves, and semi-dwarf phenotypes. Double knockout mutants, osgras19 osgras32, were then generated by crossing, and they showed similar phenotypic traits of each single mutant. Both OsGRAS19 and OsGRAS32 encoded the GRAS family proteins and were localized in the nucleus. We also confirmed that OsGRAS19 and OsGRAS32 did not directly interact with each other; however, OsGRAS19 interacted with MOC1 and SMALL ORGAN SIZE1 (SMOS1), an auxin-regulated APETALA2-type transcription factor, in yeast. Thus, we proposed OsGRAS19 as a component of the complex on the auxin-BR signaling pathway and plays role in the tiller development in rice.
