Mapping quantitative trait loci for sheath blight disease resistance in Yangdao 4 rice

Z. H. Wen, Zeng, Y. X., Ji, Z. J., and Yang, C. D., Mapping quantitative trait loci for sheath blight disease resistance in Yangdao 4 rice, vol. 14, pp. 1636-1649, 2015.

Rice sheath blight (ShB), which is caused by Rhizoctonia solani, has become the most serious rice disease in China. Yangdao 4, a cultivar with partial resistance to ShB, was crossed with Lemont, a susceptible cultivar, to develop mapping populations that were used to analyze quantitative trait loci (QTL) that confer resistance to ShB. QTL analysis were performed in 3 environments (E1-E3) using 2 F2 and 1 F2:3 populations, respectively.

Cloning and characterization of the drought-resistance OsRCI2-5 gene in rice (Oryza sativa L.)

L. Li, Li, N., Song, S. F., Li, Y. X., Xia, X. J., Fu, X. Q., Chen, G. H., and Deng, H. F., Cloning and characterization of the drought-resistance OsRCI2-5 gene in rice (Oryza sativa L.), vol. 13, pp. 4022-4035, 2014.

The genomic expression profile of the super-hybrid rice Liangyoupeijiu female parent Pei’ai 64S in different tissues at different developmental stages under low temperature, drought, and high temperature stresses were detected using an Affymetrix GeneChip Rice Genome Array to screen upregulated and downregulated genes. In this study, we screened the drought-resistant gene OsRCI2-5, after which a constitutive OsRCI2-5 construct was created and transferred into Nipponbare.

Development of 1047 insertion-deletion markers for rice genetic studies and breeding

Y. X. Zeng, Wen, Z. H., Ma, L. Y., Ji, Z. J., Li, X. M., and Yang, C. D., Development of 1047 insertion-deletion markers for rice genetic studies and breeding, vol. 12, pp. 5226-5235, 2013.

In this study, a total of 1047 insertion-deletion (InDel) primer pairs distributed across the rice genome were developed and experimentally validated. The primer pairs were designed based on the InDel length polymorphisms between 93-11 (Oryza sativa ssp indica cv.) and Nipponbare (Oryza sativa ssp japonica cv.), aiming for utilization between indica and japonica rice, or between other inter-subspecific rice cultivars.
