Abstract One hundred twenty-five endophytic microorganisms were isolated from the roots, stems, and leaves of four prominent rice cultivars growing in temperate regions. Their potential to combat rice blast disease and promote plant growth was investigated. The dual culture tests highlighted the strong antagonistic activity of five fungal (ranging from 89%–70%) and five bacterial (72%–61%) endophytes. Subsequent examination focused on volatile compounds produced by selected isolates to counter the blast pathogen. Among these, the highest chitinase (13.76 µg mL⁻¹) and siderophore (56.64%), was exhibited by Aspergillus flavus, and the highest HCN production was shown by Stenotrophomonas maltophilia (36.15 µM mL⁻¹).

Abstract Bacterial endophytes are beneficial to their hosts as they can fix nitrogen in the soil and make it available to the host. Endophytic bacteria also secrete plant growth-promoting hormones to support their host plants under normal as well as stress conditions. The current study aimed to isolate endophytic bacteria from different parts of Calotropis procera, i.e., roots, stem and leaves of Calotropis procera (Ait.) W.T. Aiton. Plants were collected from the Lundkhwar, district Mardan. A total of 12 bacterial strains, i.e., six from roots, three from the stem and three from the leaves were isolated. The strains were screened for… More >

Abstract Drought can limit the growth and reduce the yield of crops, but the safe and effective bio-approach to improve the drought resistance of crops is very little. We conducted an experiment in which we monitored the effects of polysaccharide from the endophyte Bionectria sp. Fat6 on the growth of Tartary buckwheat (Fagopyrum tataricum (L.) Gaertn) seedlings under control and drought-stressed conditions by determining gas exchange, photosynthesis parameters, photosynthetic pigment contents, and metabolite accumulation. Results indicated that the polysaccharide from endophyte stimulated plant growth and increased the aboveground biomass, root mass, and root/shoot ratio of Tartary buckwheat. Application of the polysaccharide… More >
