Plant growth and productivity are adversely affected by various abiotic stress factors. In our previous study, we used Avicennia marina, a halophytic mangrove, as a model plant system for isolating genes functioning in salt stress tolerance. A large scale random EST sequencing from a salt stressed leaf tissue cDNA library of one month old A. marina plants(More)
APX (EC, has a key role in scavenging ROS and in protecting cells against their toxic effects in algae and higher plants. A cDNA encoding a peroxisomal ascorbate peroxidase, Am-pAPX1, was isolated from salt stressed leaves of Avicennia marina (Forsk.) Vierh. by EST library screening and its expression in the context of various environmental(More)
Antifungal antibiotic from Pseudomonas chlororaphis isolate PA23 was identified as Phenazine using TLC and HPLC. Phenazine recorded the highest inhibition zone of 21 mm with 35.55% percent inhibition of mycelial growth of Pythium aphanidermatum over control. It had a significant effect on the hyphal morphology of P. aphanidermatum and on spore germination(More)
Bacillus subtilis (BSCBE4), Pseudomonas chlororaphis (PA23), endophytic P. fluorescens (ENPF1) inhibited the mycelial growth of stem blight pathogen Corynespora casiicola (Berk and Curt)Wei under in vitro. All these bacterial isolates produced both hydroxamate and carboxylate type of siderophores. But the siderophore production was maximum with the isolate(More)
Murrel namely Channa striatus or haruan contains all essential elements to maintain good health and to recover the lost energy after prolonged illness. The fatty acid composition (% of total fatty acid) indicated the abundant presence of C16:0 fatty acid as 30% and the other major fatty acids were C22:6 (15%), C20:4 (19%), C18:1 (12%) and C18:0 (15%).(More)
Bacillus subtilis strain BSCBE4 and Pseudomonas chlororaphis strain PA23 ( /P. aureofaciens) were effective biocontrol agents against Pythium aphanidermatum , the causal agent of dampingoff of hot pepper (Capsicum annum L.) in greenhouse vegetable production systems. Application of strains BSCBE4 and PA23 at the rate of 20 g kg 1 of seed significantly(More)
In preliminary screening of bacterial antagonist, B. subtilis (CBE4) isolated from rhizosphere of P. amarus was found to be effective in inhibiting the radial growth of C. cassiicola and the inhibition zone was 22.0 mm. It was followed by the endophyte P. fluorescens (ENPF1) and P. chlororaphis isolate (BCA). Biocontrol agents CBE4, BCA and ENPF1, selected(More)
