Importance of Dark Septate Endophytes in Agriculture in the Face of Climate Change

Опубликована: Март 7, 2024

Climate change is a big challenge for agriculture since it affects crop productivity and yield. The increase of droughts, salinity, soil degradation are some the main consequences climate change. use microorganisms has emerged as an alternative to mitigate them. Among these microorganisms, dark septate endophytes (DSEs) have garnered more attention in recent years. Various studies show that their association with plants helps reduce harmful effects abiotic stresses increases nutrient availability, allowing thrive under adverse conditions. This work reviews effect DSEs subjacent mechanisms will help develop higher tolerance

This study aimed to compare bacterial community structure differences in yellow paddy soil under long-term chemical/organic fertilisation and fertiliser conversion guide farmland strategies loam areas. Treatments included (1) continuous application of chemical fertilisers for 27 years (CF-CF); (2) continuously 24 then organic 3 (CF-OF); (3) (OF-OF); (4) (OF-CF). The results show that alters genus-level taxa, while mode changes significantly increase taxa quantities at both phylum genus levels. Different treatments affect the relative abundance bacteria; Firmicutes OF-OF is greater than CF-CF, Gemmatimonadota Patescibacteria opposite trend. Compared CF-OF increases decreases Cyanobacteria, whereas OF-CF compared OF-OF. Notably, enriched Cyanobacteria Bacteroidota are CF-OF, Myxomycophyta treatment. composition CF-CF similar, similar. In assembly processes, improves heterogeneous selection process reduces homogeneous dispersal gradually becomes similar CF-OF. Further analyses indicate influences by affecting total nitrogen, matter, available phosphorus, pH. Overall, different predominates distribution, short-term have a smaller but significant effect on influencing quantity taxa; more beneficial even distribution bacteria.

The establishment of artificial grassland is a good pathway for resolving serious social and economic problems in the Qinghai–Tibet Plateau. Some beneficial indigenous microbes may be used to improve productivity grassland. genome dark septate fungus, Exophiala tremulae CICC2537, was sequenced assembled at chromosome level using PacBio sequencing platform, with assistance Hi-C technique scaffolding, its 3D structures were investigated. size E. 51.903848 Mb, it contains eight chromosomes. A total 12,277 protein-coding genes predicted, 11,932 (97.19%) annotated. As distribution exon intron number gene GC CDS GC, showed similar patterns other investigated members genus Exophiala. analysis carbohydrate-active enzymes that possesses greatest auxiliary activities lowest carbohydrate-binding modules among fungi. candidate effector proteins 3337, out which cytoplasmic apoplastic made up 3100 163, respectively. whole contained 40 compartment 76 Bs, there no significant difference content Bs. predicted contain 155 topologically associating domains (TADs), their average length 250,000 bp, but differences numbers per bin localized within boundaries interiors TADs. Comparative diverged from mesophila about 34.1 (30.0–39.1) Myr ago, calicioides 85.6 (76.1–90.6) ago. Compared all fungi, contraction expansion families 13 89, respectively, 14 670, Our work provides basis use fungus alpine further research into symbiosis mechanisms, growth plant species
