Biomass is a direct reflection of community productivity, and the allocation aboveground belowground biomass survival strategy formed by long-term adaptation plants to environmental changes. However, under global changes, patterns aboveground–belowground allocations their controlling factors in different types grasslands are still unclear. Based on data 182 grasslands, including 17 alpine meadows (AMs) 21 desert steppes (DSs), this study investigates spatial distribution proportion (BGBP) main factors. The research results show that BGBP AMs significantly higher than DSs (p < 0.05). decreases with increasing mean annual temperature (MAT) precipitation (MAP) 0.05), while it increases soil nitrogen content (N), phosphorus (P), pH MAP (P) random forest model indicates most important factor affecting both DSs. Climate-related were identified as key drivers shaping exerting an influence nutrient availability. Climate exert influences not only grassland directly, but also indirectly impacting availability nutrients.

Recent advances in research on phosphate starvation signaling in plants

Journal of Plant Research, Год журнала: 2024, Номер 137(3), С. 315 - 330

Опубликована: Апрель 26, 2024

Phosphorus is indispensable for plant growth and development, with its status crucial determining crop productivity. Plants have evolved various biochemical, morphological, developmental responses to thrive under conditions of low P availability, as inorganic phosphate (Pi), the primary form uptake, often insoluble in soils. Over past 25 years, extensive research has focused on understanding these responses, collectively forming Pi starvation response system. This effort not only expanded our knowledge strategies cope (PS) but also confirmed their adaptive significance. Moreover, it identified characterized numerous components intricate regulatory network governing homeostasis. review emphasizes recent advances PS signaling, particularly highlighting physiological importance local signaling inhibiting root uncovering role TORC1 this process. Additionally, advancements shoot-root allocation a novel technique studying distribution plants are discussed. Furthermore, emerging data regulation plant-microorganism interactions by system, crosstalk between pathways starvation, phytohormones immunity, studies natural variation homeostasis addressed.

MicroRNA gatekeepers: Orchestrating rhizospheric dynamics

Journal of Integrative Plant Biology, Год журнала: 2025, Номер unknown

Опубликована: Фев. 21, 2025

ABSTRACT The rhizosphere plays a crucial role in plant growth and resilience to biotic abiotic stresses, highlighting the complex communication between plants their dynamic environment. Plants produce wide range of signaling molecules that facilitate with various factors, yet our understanding these mechanisms remains elusive. In addition protein‐coding genes, increasing evidence underscores critical microRNAs (miRNAs), class non‐coding single‐stranded RNA molecules, regulating growth, development, responses stresses under diverse factors. this review, we explore crosstalk miRNAs target mRNAs, which influence development key structures shaped by belowground Moving forward, more focused studies are needed clarify functions expression patterns miRNAs, uncover common regulatory mediate tolerance dynamics. Beyond that, propose using artificial manipulating targets through overexpression or knockout/knockdown approaches could effectively investigate roles offering significant potential for advancing crop engineering.

Arbuscular Mycorrhizal Fungi and Rhizobium Improve Nutrient Uptake and Microbial Diversity Relative to Dryland Site-Specific Soil Conditions

Microorganisms, Год журнала: 2024, Номер 12(4), С. 667 - 667

Опубликована: Март 27, 2024

Arbuscular mycorrhizal fungi (AMF) and rhizobium play a significant role in plant symbiosis. However, their influence on the rhizosphere soil microbiome associated with nutrient acquisition health is not well defined drylands of Montana (MT), USA. This study investigated effect microbial inoculants as seed treatment pea yield, uptake, potential functions, communities using high-throughput sequencing 16S ITS rRNA genes. The experiment was conducted under two contrasting dryland conditions four treatments: control, single inoculation AMF or Rhizobium, dual inoculations Rhizobium (AMF+Rhizobium). Our findings revealed that efficacy site-specific. AMF+Rhizobium synergistically increased grain yield at Sidney field site (DFS) 2, while Froid site, DFS 1, improved resilience to acidic but contributed marginal non-nutrient limiting conditions. Across sites, plants’ dependency (12%) higher than (8%) (4%) alone. Variations community structure composition indicate site-specific response inoculants. Overall, factors significantly influenced dynamics, functional potential. It underscores need for tailored management strategies consider characteristics optimize benefits from inoculation.
