Biological Management of Bacterial Leaf Blight of Rice (Xanthomonas oryzae pv. oryzae) through Rice Rhizosphere Antagonist Actinobacteria

S. Ashwini, S. K. Prashanthi, Kolur , Shruthi Mallikarjun, P. U. Krishnaraj, K. S. Iliger & Shruthi Mallikarjun Kolur · International Journal of Environment and Climate Change · 2023

Rice (Oryza sativa L.) is a staple food crop for more than two billion people around the world. Bacterial leaf blight (BLB) caused by Xanthomonas oryzae pv. oryzae (Xoo) (Ishimiya) Swings et al. is one of the most destructive diseases of rice in all the major rice-growing. Use of...

Optimization of Soil DNA Extraction Protocol Using Na2EDTA, SDS, Heating, Vortexing and CaCl2 and Its Validation for Metagenomic Studies

Malik Ahmed Pasha, Sachin A. More & P. U. Krishnaraj · International Journal of Environment and Climate Change · 2020

Aim: Several methods described previously for isolation and purification of soil DNA. Most of these protocols use combination of techniques or methods but the role and contribution of each individual method or component used is not clearly discussed. This study aims at analysing...

Diversity of Gut Bacteria in Spodoptera litura (F) and Helicoverpa armigera (Hubn) Larvae

Hanamant Gadad, A. S. Vastrad & P. U. Krishnaraj · Annual Research & Review in Biology · 2017

Gut bacterial diversity in field and laboratory strain of S. litura and H. armigera was studied USING Denaturing Gradient Gel Electrophoresis (DGGE) analysis. Results showed that field collected larvae found to be had more diverse of gut bacterial community with greater Shannon d...
