Dissecting genomic regions and underlying sheath blight resistance traits in rice ( L.) using a genome-wide association study.

The productivity of rice is greatly affected by the infection of the plant pathogenic fungus , which causes a significant grain yield reduction globally. There exist a limited number of rice accessions that are available to develop sheath blight resistance (ShB). Our objective was to identify a good source of the ShB resistance, understand the heritability, and trait interactions, and identify the genomic regions for ShB resistance traits by genome-wide association studies (GWAS).

Multi-environment evaluation of rice genotypes: impact of weather and culm biochemical parameters against sheath blight infection.

Introduction: Sheath blight caused by is one of the major diseases of rice, causing widespread crop losses. The use of semi-dwarf rice varieties in the ongoing nutrient-intensive rice cultivation system has further accentuated the incidence of the disease. An ideal solution to this problem would be identifying a stable sheath blight-tolerant genotype.

Correction: Identification of species inciting stem rot of dragon fruit in India through polyphasic approach.

Identification of species inciting stem rot of dragon fruit in India through polyphasic approach.

species commonly thrive as endophytes, saprobes, and plant pathogens in tropical and subtropical regions. Association of species causing stem rot in dragon fruit in the coastal belt of Odisha, eastern India, has been illustrated here. The stem rot disease was characterized by yellowing of the stem, followed by softening of the stem tissues with fungal fructifications of the pathogen in the affected tissues.

Developing eco-friendly biofungicide for the management of major seed borne diseases of rice and assessing their physical stability and storage life.

Three plant oils (Cymbopogon citratus, Cymbopogon martini, and Pelargonium graveolens) were developed as EC formulations and tested for their physical stabilities. EC formulations (10EC, 20EC and 30EC) of C. citratus, C.

Pathological Status of Causing Blast and Pitting Disease of Banana in Eastern India.

Incidence of leaf blast on nursery plants and pitting disease on maturing banana bunches has been recorded in banana plantations during rainy season in Eastern India during 2014 to 2015. Taxonomical identification as well as DNA sequence analysis of the internal transcribed spacer region of fungus isolated from affected tissue culture derived plantlets and fruits confirmed the pathogen to be Hashioka "in both the cases". Koch's postulates were proved on young plantlets as well as on maturing fruits of cv.
