We isolated 10 endophytic fungi from the roots of drought stressed soybean cultivar Hwangkeumkong and bioassayed on waito-c rice and soybean seedlings, in order to identify plant growth-promoting fungi. The fungal isolate D-2-1 provided the best result for plant height and biomass promotion as compared to wild type Gibberella fujikuroi. The D-2-1 culture filtrate (CF) was analyzed for the presence of gibberellins (GAs) and it was observed that all physiologically active GAs, especially gibberellic acid, were present in higher amounts (GA1, 0.24 ng/ml; GA3, 8.99 ng/ml; GA4, 2.58 ng/ml and GA7, 1.39 ng/ml) in conjunction with physiologically inactive GA5, GA9, GA15, GA19, and GA24. The fungal isolate D-2-1 was identified as a new strain of Chrysosporium pseudomerdarium through phylogenetic analysis of 18S rDNA sequence. Plant growth promotion and GAs production capacity of genus Chrysosporium have been reported for the first time in this study.

The importance of the microbiome in the functioning of degraded lands in industrialised zones is significant. However, little is known about how environmental parameters affect microbial abundance, structure, diversity, and especially specific guilds involved in the nitrogen cycle in saline soils influenced by the soda industry. To address this knowledge gap, our research focused on assessing the microbiota in relation to soil properties and plant species composition across two transects representing different types of land use: saline wasteland and arable fields.

Out of seven fungal species belonging to four genera isolated from pond and wallow soils using feathers of Pavo cristatus as bait, four species viz., Aspergillus flavus, Aspergillus niger, Chrysosporium pseudomerdarium and Trichophyton ajelloi were most frequent. Chrysosporium and Trichophyton spp.
