To evaluate the potential of chitinolytic endophytic Actinomycetes isolated from medicinal plants in order to diminish collar rot infestation induced by Sclerotium rolfsii chickpea.Sixty-eight were recovered various and evaluated for their chitinase activity. Among these isolates, 12 screened plant growth promoting abilities antagonistic against Sc. rolfsii. Further, isolates validated vivo ability protect chickpea under greenhouse conditions. The significantly (P < 0·05) increased biomass...

Phytoplasma, a potentially hazardous pathogen associated with witches' broom, is an economically harmful disease-producing bacteria that damages chilli cultivation. Phytoplasma-infected plants display various symptoms indicate significant disruptions in normal plant physiology and behaviour. Diseases caused by phytoplasma are widespread have major economic impact on crop quality yield. This work focuses identifying examining microRNAs (miRNAs) as potential targets against the 16S rRNA secA...

Weeds are widely distributed throughout the world and have high environmental adaptability. considered as a source of new viruses reservoirs unidentified economically important but often neglected during diversity studies. Many scientific reports demonstrated that weeds serve reservoir or alternative hosts for begomovirus (family Geminiviridae) survival spread in absence main crops. Thus, there is pressing need additional information on distribution begomoviruses associated weeds, which...

Chilli (Capsicum annuum L.) is an important vegetable and spice crop of tropical sub-tropical regions. plants showing upward leaf curling, crinkling, yellowing symptoms, collected from Sikar district Rajasthan, India, were found to be associated with begomovirus satellite molecules. The presence virus was confirmed by PCR using virus-specific primer. full-length genomic DNA-A three (MM-1, CS-1 RV-1) two satellites (MM-2 MM-3) cloned which identified single symptomatic chilli plant. genome...

India has a huge potential for numerous crops production which are proficiently valued small grower to the highest producers. Considering, social and economic applicability, especially in case of productivity both quality as well quantity. Multiple factors stick with economically important crops, among all, plant viruses predominant. Emphasising begomovirus emerged severe constraints many tropical sub-tropical regions. The largest genus Begomovirus naturally transmitted by whiteflies...

The genus Begomovirus represents a group of multipartite viruses that significantly damage many agricultural crops, including papaya, and influence overall production. Papaya leaf curl disease (PaLCD) caused by the complex begomovirus species has several important implications substantial losses in papaya production developing countries, India. increase number poses continuous threat to papaya. Here, we attempted map genomic variation, mutation, evolution rate, recombination know complexity...
