Abstract To provide a scientific basis for controlling mulberry bacterial blight in Bazhong, Sichuan, China (BSC), this study aimed to isolate and purify pathogenic bacteria from diseased branches of mulberry trees in the region and to clarify their taxonomic status using morphological observation, physiological and biochemical detection, molecular-level identification, and the construction of a phylogenetic tree. A total of 218 bacterial strains were isolated from samples of diseased mulberry branches. Of these, 7 strains were identified as pathogenic bacteria based on pathogenicity tests conducted in accordance with Koch’s postulates. Preliminary findings from the analysis of the More >

Abstract The basic leucine zipper (bZIP) is an important class of transcription factors in plants, playing a critical role in plant growth and development and responses to biotic and abiotic stress. Due to gene presence/absence variations, it is limited to identify bZIP genes based on the reference genome. Therefore, we performed the bZIP gene family analysis in the rice pan-genome. By employing a rice pan-genome, ninety-four OsbZIPs (72 core genes and 22 variable genes) were identified and divided into 11 groups in a phylogenetic tree. Based upon Ka/Ks values in 33 accessions, OsbZIPs were subjected to different selection… More >

Abstract In order to identify genes of resistance to four diseases that affect Phaseolus sp. [i.e, Common Bacterial Blight (CBB), Bean Common Mosaic Virus (BCMV), Bean Golden Mosaic Virus (BGMV) and angular leaf spot (ALS)], we amplified nine SCAR (Sequence Characterized Amplified Regions) markers: four linked to resistance to common blight, two for BCMV, two for BGMV and one for ALS. The genetic material included 16 ayocote bean (P. coccineus) populations collected from different locations at Veracruz and Puebla, Mexico. Populations from Veracruz showed greater number of SCARs for BGMV and ALS compared with populations from Puebla. More >
