The cadaverine (Cad), an organic diamine was examined for its response on growth in salinity and metal stressed B. juncea cv RH-30 vis-à-vis compared the response of ammonium nitrate. The Cad (1 mM) application ameliorated the effect caused by salinity and metal stress on seed germination and plant growth. The plant growth recovery (dry biomass accumulation) was dependent on stress and diamine ...

To investigate the mechanism of auxin action during pattern formation in dicot embryos, we tested the effects of the natural auxin indole-3-acetic acid (IAA), the auxin transport inhibitor N-(1-naphthyl)thalamic acid (NPA) and the antiauxin p-chlorophenoxyisobutyric acid (PCIB). In vitro treatments of isolated zygotic Brassica juncea embryos with these substances led to a wide range of morphoge...

To facilitate plant colonization, some pathogenic fungi produce phytotoxic metabolites that damage tissues; plants may be resistant to a particular pathogen if they produce an enzyme(s) that catalyzes detoxification of this metabolite(s). Alternaria blackspot is one of the most damaging and significant fungal diseases of brassica crops, with no source of resistance known within the Brassica spe...

Glucosinolates are sulphur containing secondary metabolites biosynthesized by many plant species in the order Brassicales. Physical tissue or cell injury leads to the breakdown of glucosinolates through the hydrolytic action of the enzyme myrosinase, resulting in the production of compounds including isothiocynates, thiocyanates and nitriles. Derivative compounds of glucosinolates have a wide r...

The aim of present study was to understand how the ultrastructure leaf mesophyll cells in Brassica can be altered under elevated CO2 by interactive effect on anatomy and ultra structure species moisture stress conditions. Results experiment revealed that crop genotypes differ greatly response Elevated brought about an increase cell chloroplast expansion genotypes. also increased thickness epide...

The objective of this study was to analyze the nutritional, antinutritional and mineral compositions of eight locally available underutilized green leafy vegetables of Sonitpur district of Assam, India. Moisture and ash of the green leafy vegetables were in the range of 71.7498.20 g / 100 g and 8.23-26.01 g / 100 g respectively. Fiber was higher in Basella rubra (8.61 g / 100 g) and lower in Mo...

Insect herbivores often have higher densities on host plants grown in monocultures than those in diverse environments. The underlying mechanisms are thought to be that polyphagous insects have difficulty in selecting food or oviposition sites when multiple host plants exist. However, this hypothesis needs to be extensively investigated. Our field experiments revealed that the population of the ...
