Vochysia haenkeana extract (Vh-E) was assessed against the neuromuscular blockade induced by Bothrops jararaca venom on chick biventer cervicis (BC) preparation. Pre- and post-venom incubation treatments (Pre-vit and Post-vit) were analysed here. Contractures ACh (110 μM) and KCl (20 mM) were evoked before and after addition of venom without stimulation.

Agrobacterium rhizogenesATCC 15834 wild type strain was transformed with the binary vector pBI121 using the heat shock method. The transformed Agrobacterium was then tested for virulence through tobacco leaf explant transformation. Compared to the non-transformed Agrobacterium, the transformed Agrobacterium showed reduced virulence, producing significantly lower number of hairy roots in tobacco leaf explants.

Soil dwelling bacteria able to colonize plant roots and closely associated soil are referred to as rhizobacteria. A wide range of rhizobacteria has the ability to promote plant growth directly by producing phytohormone and nutrients; and indirectly by controlling plant pathogen. These beneficial bacteria are known as plant growth promoting rhizobacteria (PGPR). PGPR control phytopathogens by producing chemicals that could damage pathogen cells, removing pathogen specific nutrients from the environment, or inducing resistance against pathogen in plant body.

The present study was aimed to screen and quantify the phytochemicals by qualitative and quantitative analysis in methanol and aqueous leaf and stem extracts of Marsilea quadrifolia (L.). In qualitative analysis, the phytochemical compounds such as tannins, saponins, flavonoids, steroids, terpenoids, triterpenoids, alkaloids, carbohydrates, proteins, anthroquinones, phenolic compounds and phytosterol were screened.

In this study we proposed carbonic anhydrase (CA) asan important element of basal resistance during the potato (Solanum tuberosum L.)-Phytophthora infestans interaction.We found a different β-CAexpression pattern in incompatible vs. compatible systems correlated in time with CA enzyme activity.

Calcium phosphates are of great interest in medicine, biology, agriculture and materials sciences. The present study evaluates the effect of calcium phosphates nanoparticles on biochemical changes in rice. Nanoparticles increased the growth rate and affect the physiology of the plant. Calcium phosphate nanoparticles may help in the formulation of new nano growth promoter and nano-fertilizers for agricultural use.
