Climate change and agriculture are intrinsically connected sudden changes in climatic conditions adversely impact global food production security. The climate change-linked abiotic stressors like drought high temperatures resulting crop failure. most severe stress significantly affect the stomatal closure, of reactive oxygen species, transpiration, photosynthesis or other physiological processes plant morphology, growth yield. Therefore, there is an exigent need for cost effective eco-friendly modern technologies to induce tolerance plants leading climate-adapted sustainable agricultural practices sustained production. Among many options being pursued this regard, use promoting microbes (PGPMs) approach promote resilience better productivity. These PGPMs confer resistance via various direct indirect mechanisms including antioxidants, enzymes, exopolysaccharides, modulation phytohormones level, osmotic adjustment by inducing accumulation sugars, along with increases nutrients, water uptake photosynthetic pigments. However, several technological ecological challenges limit their sometimes treatment beneficial fails produce desired results under field conditions. Thus, development synthetic microbial communities host mediated microbiome engineering transgenic capacity express traits may survival present review critically assesses research evidence on potentials genes as develop resilient increased Effective collaboration among scientific communities, policymakers regulatory agencies needed create strong frameworks that both regulate utilization agriculture.

Advances in the beneficial endophytic fungi for the growth and health of woody plants

Forestry Research, Journal Year: 2024, Volume and Issue: 4(1), P. 0 - 0

Published: Jan. 1, 2024

In recent years, the importance of microorganisms for plant survival has been increasingly recognized. Endophytic fungi, as part holobiont, can confer growth advantages to plants. Most studies have shown that endophytic fungi forest trees promote host growth, increase adversity resistance, and thus improve competitiveness trees. However, beneficial examples on development woody plants not systematically summarized. This review is focused various aspects in (definition, classification, colonization mechanisms, etc.), with an emphasis their roles protection against biotic abiotic stresses, well response fungi. addition, this lists a series experiments screening from Chinese fir (

Screening and transcriptomic profiling of tobacco growth-promoting arbuscular mycorrhizal fungi

Plant Signaling & Behavior, Journal Year: 2025, Volume and Issue: 20(1)

Published: Feb. 19, 2025

Tobacco is a significant economic crop cultivated in various regions of China. Arbuscular mycorrhizal fungi (AMF) can establish symbiotic relationship with tobacco and regulate its growth. However, the influences indigenous AMF on growth development their mechanisms remain unclear. In this study, pot inoculation experiment was conducted, revealing that six inoculants - Acaulospora bireticulata(Ab), Septoglomus viscosum(Sv), Funneliformis mosseae(Fm), Claroideoglomus etunicatum(Ce), Rhizophagus intraradices(Ri), mixed inoculant (H) – all formed stable relationships tobacco. These were found to enhance activities SOD, POD, PPO, PAL leaves, increase chlorophyll content, IAA CTK soluble sugars, proline levels while reducing malondialdehyde content. Notably, among these inoculants, Fm exhibited significantly higher infection density, arbuscular abundance, soil spore density root systems plants compared other treatments. Membership function analysis confirmed had most pronounced growth-promoting effect The transcriptome results different treatments CK revealed 3,903 genes upregulated 4,196 downregulated roots stems Enrichment indicated majority annotated related pathways such as biological processes, molecular functions, metabolism. Furthermore, differentially expressed associated auxin, cytokinin, antioxidant enzymes, carotenoids enriched respective pathways, potentially indirectly influencing regulation plant This study provides theoretical foundation for application

Hormonal changes associated with arbuscular mycorrhizal fungi indicate defense‐like alterations in virus‐stressed grapevine

Physiologia Plantarum, Journal Year: 2025, Volume and Issue: 177(1)

Published: Jan. 1, 2025

Abstract Grapevine is an economically important crop, affected by major production losses due to high virus prevalence. Arbuscular mycorrhizal fungi (AMF) can reduce the impact of plant biotic stresses. However, hormonal response simultaneous presence viruses and AMF remains largely unknown. In this study, we explored potential modify grapevine's defense compatible infections. We used GRSPaV, GLRaV‐3, GPGV as infectious viral agents, separately or in different combinations. Two inoculums were tested for their bioprotective abilities, RHIZ ( Rhizophagus irregularis) MIX R. irregularis , Funneliformis mosseae F. caledonium ). Generally, induced stronger physiological responses than inoculum, especially during earlier phase symbiosis. The main findings connected profile grapevine infected all three inoculated with MIX. particular, salicylic acid (SA) abscisic (ABA) concentrations five fifteen months post inoculation, respectively. Expressions VvNCED1 VvBG1 up‐regulated uninoculated grapevines, indicating slower induction stress mechanisms. Parameters related vigour growth at both time points, regardless combination. conclusion, defense‐like grapevines multiple characterized ABA SA, accompanied a consistent enhancement vigor parameters. This study confirms symbiosis potentially promising additional tool combating diseases vineyards.

MdPHR2 and MdARF6‐4 synergistically regulate arbuscular mycorrhizal symbiosis and the transcription of MdPHT1;13, enhancing phosphorus uptake in apple rootstocks

The Plant Journal, Journal Year: 2025, Volume and Issue: 121(5)

Published: March 1, 2025

Phosphorus in the soil is easily chelated into forms that are unavailable to plants, leading phosphorus deficiency, which severely affects growth, development, and fruit quality of apple trees. To address we used four different arbuscular mycorrhizal fungi (AMF) investigate their effects on growth development rootstocks uptake soil. We identified Glomus mosseae (Gm) as most effective AMF for promoting found under phosphorus-deficient conditions, inoculating with Gm promoted above-ground parts plants absorption, while it inhibited root growth. After fungi, starvation response factors (PHRs) auxin (ARFs) were upregulated. Knockdown MdPHR2 or MdARF6-4 resulted decreased structures, total colonization rate, content, indicating positively regulate symbiosis absorption. In contrast, overexpressing led reduced but increased content inoculation, suggesting involved Gm-mediated absorption development. Moreover, both directly bound promoter area downstream transporter MdPHT1;13, these two transcription interacted each other vivo vitro. summary, our study demonstrates interaction between synergistically regulates thereby rootstocks.
