The use of peptide hydrolase (EC 3.4.13.1) from Xanthomonas rubrilineans for synthesis of the antibiotic cephalexin from 7-aminodesacetoxycephalosporanic acid was studied. The optimum conditions for production of cephalexin were determined, and the yield exceeded 80%. A method for monitoring the synthesis of this antibiotic synthesis by means of a conventional amino acid analyzer is proposed.

Acidovorax avenae subsp. avenae (Aaa) is the causal agent of red stripe in sugarcane, a disease characterized by two forms: leaf stripe and top rot. Despite the importance of this disease, little is known about Aaa virulence factors (VFs) and their function in the infection process.

Auxin response factor (ARF) is a critical regulator in the auxin signaling pathway, involved in a variety of plant biological processes. Here, gene members of 24 and 39 were identified in two genomes of clones AP85-441 and Np-X, respectively. Phylogenetic analysis showed that all genes were clustered into four clades, which is identical to those genes in maize () and sorghum ().

Bacterial panicle blight, bacterial leaf streak, and bacterial brown stripe are common bacterial diseases in rice that represent global threats to stable rice yields. In this study, we used the rice variety HZ, Nekken and their 120 RIL population as experimental materials. Phenotypes of the parents and RILs were quantitatively analyzed after inoculation with , pv.

In recent years subsp. was identified as a major cause of bacterial etiolation and decline (BED) in turfgrasses and has become a growing economical concern for the turfgrass industry. The symptoms of BED resemble those of "bakanae," or foolish seedling disease, of rice (), in which the gibberellins produced by the infecting fungus, , contribute to the symptom development.

Article Synopsis
- Sugarcane is a vital cash crop used for sugar and bioethanol, but it's threatened by a disease called red stripe caused by a specific subspecies.
- A study isolated 17 strains of this bacteria from symptomatic sugarcane leaves in China, revealing two distinct colony color morphologies and high genetic similarity among the strains.
- The research found that these strains showed unique evolutionary patterns and differed in their disease impact on sugarcane, indicating a complex interplay of genetic variation and local adaptation in the pathogens causing red stripe.
