Improved Tolerance of Artemisia ordosica to Drought Stress via Dark Septate Endophyte (DSE) Symbiosis

Journal of Fungi, Journal Year: 2022, Volume and Issue: 8(7), P. 730 - 730

Published: July 13, 2022

Dark septate endophytes (DSEs) usually colonize plant roots, especially in stress environments. However, their relationship with plants ranges from beneficial to harmful and has remained largely uncharacterized. In the present study, 14 DSE species grouped into 11 genera were isolated roots of a desert plant, Artemisia ordosica, which is widely distributed northwest China. Three dominant species-Paraphoma chrysanthemicola (Pc), Alternaria chartarum (Ac), Acrocalymma vagum (Av)-were selected tested for resistance drought vitro. Furthermore, we characterized responses A. ordosica under conditions relation presence these DSEs following inoculation. The results showed that all three strains grew well vitro stress, biomass Ac Av was significantly higher than unstressed control. effects inoculation on growth varied according different but generally beneficial. Under Pc promoted growth, antioxidant enzyme activity, root development hosts. strain conferred obvious positive activity general, demonstrated better application potential improving ordosica.

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

Journal of Fungi, Journal Year: 2024, Volume and Issue: 10(5), P. 329 - 329

Published: April 30, 2024

Climate change is a notable challenge for agriculture as it affects crop productivity and yield. Increases in droughts, salinity, soil degradation are some of the major consequences climate change. The use microorganisms has emerged an alternative to mitigate effects Among these microorganisms, dark septate endophytes (DSEs) have garnered increasing attention recent years. Dark shown capacity mitigating reducing harmful agriculture, such drought, reduced nutrient availability soil. Various studies show that their association with plants helps reduce abiotic stresses increases availability, enabling thrive under adverse conditions. In this study, effect DSEs underlying mechanisms help develop higher tolerance were reviewed.

Complementary Effects of Dark Septate Endophytes and Trichoderma Strains on Growth and Active Ingredient Accumulation of Astragalus mongholicus under Drought Stress

Journal of Fungi, Journal Year: 2022, Volume and Issue: 8(9), P. 920 - 920

Published: Aug. 30, 2022

Drought is a major abiotic stress factor affecting plant growth and production, while utilizing beneficial endophytic fungi one of the most promising strategies for enhancing drought tolerance. In current study, pot experiment was conducted to investigate effects dark septate endophyte (DSE) (Macrophomina pseudophaseolina, Paraphoma radicina) Trichoderma (Trichoderma afroharzianum, longibrachiatum) inoculum on Astragalus mongholicus grown in sterile soil under stress, alone, or combination. The addition enhanced DSE colonization roots regardless water condition. Under well-watered conditions, M. pseudophaseolina inoculation significantly biomass root length A. mongholicus. two improved calycosin-7-O-β-D-glucoside content. However, + T. afroharzianum better promoted growth, whereas co-inoculation had higher active ingredient contents compared with single inoculation, except P. radicina afroharzianum. biomass, length, content, activities nitrate reductase urease. longibrachiatum increased all combinations greater impact increase formononetin content treatments. Additionally, relies antioxidant enzymes, hormones, redox system (ascorbic acid−glutathione) resist drought, strains have an additional osmotic regulation resistance function possessed by Trichoderma, effect (especially afroharzianum) physiological parameters than that inoculation. This study provides new research direction medicinal cultivated dryland.
