A cross-resistance of Pyricularia oryzae Cavara to kasugamycin and blasticidin S.

A cross resistance of pathogenic organisms to various chemicals has been increasing over a long period of time causing serious problems in the field of antibacterial drugs and veterinary drugs. Recently, it was reported that some phytopathogenic bacteria and fungi resistant to antibiotics and synthetic fungicides were isolated from diseased plants in the field and that distribution of resistant...

Acquired Tolerance to Blasticidin-S in Pyricularia oryzae

HWANG, B. K., and H. S. CHUNG. 1977. Acquired tolerance to Blasticidin-S in Pyricularia oryzae. Phytopathology 67: 421-424. Thirteen naturally-occurring isolates of Pyricularia oryzae transfers on fungicide-free media. Successive monoconidial varied in tolerance to Blasticidin-S [l-(1'-cytosinyl)-4-[L-3'cultures of Bu7 were genetically homogeneous for tolerance. amino-5-(l"-N-methylguanidino) v...

Genetic variation in resistance to blast (Pyricularia oryzae Cavara) in rice (Oryza sativa L.) germplasms of Bangladesh

Genetic variation in blast resistance was clarified in 334 Bangladesh rice accessions from 4 major ecotypes (Aus, Aman, Boro and Jhum). Cluster analysis of polymorphism data of 74 SSR markers separated these accessions into cluster I (corresponding to the Japonica Group) and cluster II (corresponding to the Indica Group). Cluster II accessions were represented with high frequency in all ecotype...

A Chemical-Genomic Screen of Neglected Antibiotics Reveals Illicit Transport of Kasugamycin and Blasticidin S

Fighting antibiotic resistance requires a deeper understanding of the genetic factors that determine the antibiotic susceptibility of bacteria. Here we describe a chemical-genomic screen in Escherichia coli K-12 that was designed to discover new aspects of antibiotic resistance by focusing on a set of 26 antibiotics and other stresses with poorly characterized mode-of-action and determinants of...
