Rice is an important staple food for more than half of the world’s population. Though genetic potential commonly cultivated varieties rice diminished due to various biotic and abiotic constraints, bacterial leaf blight (BLB) caused by Xanthomonas oryzae pv. (Xoo) considered one its most destructive diseases in India. Based on morpho-cultural characteristics, pathogens isolated from leaves a pla...

Mikania micrantha (Asteraceae: Eupatorieae), widely called mile-a-minute, has been a persistent problem to forestry, plantations and biodiversity conservation in southwestern and northeastern India, as well as in Andaman and Nicobar islands. To supplement the previously imported Trinidad-originating Puccinia spegazzinii (Pucciniales: Pucciniaceae), a different pathotype (IMI 393076) was importe...

Larvae of manuka beetles, Pyronota spp. (Coleoptera: Scarabaeidae) cause pasture damage in New Zealand by feeding on the roots of grasses. Surveys for potential biocontrol agents revealed a putative disease, expressed as whitened larvae of one of the outbreak species, Pyronota setosa. Microbial diagnosis indicated an intracoelomic, intracellular infection, and intracellular bacteria have been i...

The filamentous fungus Alternaria alternata contains seven pathogenic variants (pathotypes), which produce host-specific toxins and cause diseases on different plants. Previously, the gene cluster involved in host-specific AK-toxin biosynthesis of the Japanese pear pathotype was isolated, and four genes, named AKT genes, were identified. The AKT homologs were also found in the strawberry and ta...

Plasmodiophora brassicae is an obligate biotroph that causes clubroot, one of the most damaging diseases of crucifers. Differential cultivars and random amplified polymorphic DNA markers were used to assess the extent of genetic diversity among nine single-gall populations of P. brassicae and 37 single-spore isolates (SSI) derived from four of those field samples. Isolates were classified into ...

One of major objectives of crop breeding is conferring resistance to diseases and pests. However, large-scale phenotypic evaluation for many diseases and pests is difficult because strict controls are required to prevent their spread. Detection of disease resistance genes by using DNA markers may be an alternative approach to select potentially resistant accessions. Potato (Solanum tuberosum L....

Introduction . Klebsiella pneumoniae in human microbiota may appear as a part of commensal microbiota, and hypervirulent pathogen, for example, hypermucoid pathotype. This pathotype is characterized by certain genetic determinants, leading to the possibility detecting pathogenic potential isolates PCR. Aim study : evaluate compare K. from practically healthy people, patients with inflammatory b...

Wheat blast, caused by a fungal pathogen, Magnaporthe oryzae Tritichum (MoT) pathotype (wheat isolates), was first reported in Bangladesh among Asian countries 2016. It is serious disease of wheat causing yield failures and significant economic losses during epidemic years. Extensive use persistent synthetic pesticides to control notorious blast imposes enormous threat human health environment....
