An introgression line RBPH660,derived from wild rice Oryza rufipogon,showed stable resistance to brown planthopper(BPH).Segregation analysis indicated BPH resistance of RBPH660 was controlled by multiple genes/*** using the bulked segregant analysis(BSA)-seq method,two genomic regions harboring QTLs resistance to BPH were identified from 1.20 to 16.70 Mb on chromosome 4 and from 10.20 to 12.60 Mb on chromosome 9 in RBPH660,respectively.A major resistance locus,designated as Bph35 accounting for 51.27%of the phenotypic variation with a LOD score of 42.51,was mapped to the candidate region of chromosome 4 between In Del(insertion-deletion)markers PSM16 and R4 *** fine mapping of Bph35,one simple sequence repeat and three newly developed In Del markers were used to screen the ***,the Bph35 locus was delimited in the region from 6.28 to 6.93 Mb and there were 18 predicted protein-encoding genes with a total of 114 non-synonymous single nucleotide polymorphism(SNP)variant sites between the resistant and susceptible *** of these genes,Os04 g0193950,encoding a putative NB-ARC(nucleotidebinding adaptor shared by APAF-1,R proteins and CED-4)and LRR(leucine-rich repeat)domain protein with nine non-synonymous SNP substitutions in its coding sequence regions,might be the candidate gene for *** findings would facilitate the map-based cloning of the Bph35 gene and development of resistant varieties against BPH in rice.

以紫色红曲霉M9为研究对象,研究不同单色光对其生长、色素和桔霉素合成的影响。采用观察法和高效液相色谱法对紫色红曲霉M9在持续红光、黄光、绿光、蓝光照射下的菌落形态及6种红曲色素产量进行研究。采用高效液相色谱法和RT-qPCR法对不同红光光照时间和光照强度下红曲色素和桔霉素产量以及相关基因表达量进行测定。结果表明,红光是最显著的促进紫色红曲霉M9生长和色素产生的光源。高产红曲色素、低产桔霉素的最佳光照时间和强度分别为30 min/d和300 lx,初步推测红曲色素合成相关基因mppA/B/D/F、mppR1/R2、MpPKS5、MpFasA2/B2可能参与两种橙色素的生物合成,mppC、mppE可能参与两种红色素和两种黄色素的生物合成;桔霉素合成相关基因ctnA/D/E/F/G/H/I、orf1/3/4/5、pksCT可能参与桔霉素的合成代谢,而ctnR1可能参与桔霉素的分解代谢。
