Evaluation of biocontrol efficacy of rhizosphere dwelling bacteria for management of Fusarium wilt and Botrytis gray mold of chickpea.

Background: Chickpea (Cicer arietinum L.) production is affected by many biotic factors, among them Fusarium wilt caused by Fusarium oxysporum f. sp.

Brassica juncea leaf cuticle contains xylose and mannose (xylomannan) which inhibit ice recrystallization on the leaf surface.

Conjugated sugars showed antifreeze activity in the cuticle by ice recrystallization inhibition rather than thermal hysteresis, enhancing freezing capacity at the surface of B. juncea leaves. Antifreeze biomolecules play a crucial role in mitigating the physical damage from frost by controlling extracellular ice crystal growth in plants.

Morphological characterization, pathogenicity screening, and molecular identification of spp. isolates causing post-flowering stalk rot in maize.

Post flowering stalk rot (PFSR) of maize caused by the species complex is a serious threat to maize production worldwide. The identification of species causing PFSR based on morphology traditionally relies on a small set of phenomic characteristics with only minor morphological variations among distinct species. Seventy-one isolates were collected from 40 sites in five agro-climatic zones of India to assess the diversity of spp.

Brassica juncea leaf cuticle proteome analysis shows myrosinase protein, antifreeze activity, and post-translationally modified secretory proteins.

Plant cuticle, the site of perception of stress signals, is an extracellular hydrophobic barrier that covers the epidermis of the above-ground parts. This lipidic layer has been explored for its cutin and wax composition. However, reports on the cuticle proteins are scanty.

A Novel Seed-Dressing Formulation Based on an Improved Mutant Strain of , and Its Field Evaluation.

Using gamma-ray-induced mutagenesis, we have developed a mutant (named G2) of that produced two- to three-fold excesses of secondary metabolites, including viridin, viridiol, and some yet-to-be identified compounds. Consequently, this mutant had improved antibiosis against the oomycete test pathogen . A transcriptome analysis of the mutant vis-à-vis the wild-type strain showed upregulation of several secondary-metabolism-related genes.

Simultaneous Detection of Mixed Infection of Onion yellow dwarf virus and an Allexivirus in RT-PCR for Ensuring Virus Free Onion Bulbs.

Reduced seed production in onion is associated with Onion yellow dwarf virus (OYDV), a filamentous Potyvirus. Onion is also infected with other filamentous virus particles suspected to be Allexivirus. RT-PCR was used to detect mixed infection of both the viruses in leaves and bulbs.

An impression of coffee carbohydrates.

Coffee is one of the most popular beverages in the world. It is consumed for its refreshing and stimulating properties. Carbohydrates are the major constituents of coffee beans and serve various functions like binding of aroma, stabilization of foam, formation of sedimentation, and increased viscosity of the extract.
