The Asian citrus psyllid (ACP) is a citrus pest and insect vector of " Liberibacter asiaticus", the causal agent of citrus greening disease. Double-stranded RNA (dsRNA) biopesticides that trigger RNA interference (RNAi) offer an alternative to traditional insecticides. Standardized laboratory screening of dsRNA requires establishing the minimal effective concentration(s) that result in effective RNAi "penetrance" and trigger RNAi, resulting in one or more measurable phenotypes, herein, significant gene knockdown and the potential for mortality.

Endochitinases () gene of family 18 glycosyl hydrolyses were amplified, cloned and characterized from genomic DNA of two isolates of Catalytic motif of family 18 glycosyl hydrolyses was found in of , while no signal peptide was found in any isolate, whereas substrate-binding motif was found in of both isolates. Phylogenetic analysis revealed the evolutionary relationship among the fungal chitinases of .

Despite the harmful effect of Bipolaris and Curvularia species, scarce attention is paid on beneficial areas where the fungi are used in industrial processes to generate biotechnological products. Catalytic potential of Bipolaris and Curvularia species in the production of biodiesel, bioflucculant, biosorbent, and mycoherbicide are promising for the bioeconomy.

Despite the success of biotech ()/herbicide tolerance (HT)-soybean in the past decade in terms of output, unforeseen mitigated performances have been observed due to changes in climatic events that favors the emergence of insect resistance.

The aim of this study was holistically to investigate morphological and immunoadaptations and their implication in antifungal resistance and proliferation during infection.
Materials And Methods: In-depth unstructured mining of relevant peer-reviewed literature was performed for morphological, immune, resistance, and genetic diversity based on the sequenced calmodulin-like gene.
Matching the global food demand by 2050 and to ensure the stability of food security in over than 99 countries, it is necessary to scale up the production of food such as sorghum, wheat, rice, maize and sugarcane which are however natural hosts of Cochliobolus species. Cochliobolus species major epidemics such as the Great Bengal famine, Southern corn leaf blight, and Northern leaf spot blight were associated with substantial economic losses in the past decades. Thus, there is an urgent need to establish a specific coordinated global surveillance program for the migration of invasive Cochliobolus species, planning contextual control programs engaging all agricultural stakeholders and information sharing in real time for prevention of disastrous Cochliobolus disease outbreak effects.
