Rice- transcriptomics reveals host defense activation induced by red seaweed-biostimulant in rice plants.

Red seaweed extracts have been shown to trigger the biotic stress tolerance in several crops. However, reports on transcriptional modifications in plants treated with seaweed biostimulant are limited. To understand the specific response of rice to blast disease in seaweed-biostimulant-primed and non-primed plants, transcriptomics of a susceptible rice cultivar IR-64 was carried out at zero and 48 h post inoculation with (strain MG-01).

Transcriptomic responses under combined bacterial blight and drought stress in rice reveal potential genes to improve multi-stress tolerance.

Background: The unprecedented drought and frequent occurrence of pathogen infection in rice is becoming more due to climate change. Simultaneous occurrence of stresses lead to more crop loss. To cope up multiple stresses, the durable resistant cultivars needs to be developed, by identifying relevant genes from combined biotic and abiotic stress exposed plants.

Host range and virulence diversity of Pectobacterium carotovorum subsp. brasiliense strain RDKLR infecting radish in India, and development of a LAMP-based diagnostics.

Aim: This work aimed at determining the pathogenicity, molecular characterization, host range and rapid detection of Pectobacterium carotovorum subsp. brasiliense (Pcb) causing soft rot disease in radish.

Methods And Results: The four isolated isolates were inoculated to radish, typical soft rot symptoms were observed and Koch's postulates were proved.

Comparative Transcriptome Analysis of Rice Resistant and Susceptible Genotypes to Xanthomonas oryzae pv. oryzae Identifies Novel Genes to Control Bacterial Leaf Blight.

The bacterial leaf blight in rice caused by Xanthomonas oryzae pv. oryzae (Xoo) affects crop losses worldwide. In spite of developing resistant varieties by introgressing different Xa genes, the occurrence of diseases is evident.
