Mycorrhizal Symbiosis in Plant Growth and Stress Adaptation: From Genes to Ecosystems

Annual Review of Plant Biology, Год журнала: 2023, Номер 74(1), С. 569 - 607

Опубликована: Март 1, 2023

Plant roots associate with diverse microbes (including bacteria, fungi, archaea, protists, and viruses) collectively called the root-associated microbiome. Among them, mycorrhizal fungi colonize host improve their access to nutrients, usually phosphorus nitrogen. In exchange, plants deliver photosynthetic carbon colonizing fungi. This nutrient exchange affects key soil processes, cycle, plant health therefore has a strong influence on microbe ecosystems. The framework of regulation between arbuscular recently been established. local systemic symbiosis by status autoregulation mycorrhizae are strategies which maintain stabilizing free-market symbiosis. A better understanding synergistic effects mycorrhizosphere microorganisms is an essential precondition for use as biofertilizers bioprotectors sustainable agriculture forestry management.

Mechanisms underlying legume–rhizobium symbioses

Journal of Integrative Plant Biology, Год журнала: 2021, Номер 64(2), С. 244 - 267

Опубликована: Дек. 28, 2021

Abstract Legumes, unlike most land plants, can form symbiotic root nodules with nitrogen‐fixing bacteria to secure nitrogen for growth. The formation of on legume roots requires the coordination rhizobial infection at epidermis cell division in cortex. house rhizobia organelle‐like structures known as symbiosomes, which enable fixation and facilitate exchange metabolites between host symbionts. In addition this beneficial interaction, legumes are continuously exposed would‐be pathogenic microbes; therefore ability discriminate pathogens from symbionts is a major determinant plant survival under natural conditions. Here, we summarize recent advances understanding nodule symbiosis signaling, transcriptional regulation, regulation immunity during legume–rhizobium symbiosis. addition, propose several important questions be addressed provide insights into potential engineering capacity fix non‐legume plants.

PHOSPHATE STARVATION RESPONSE transcription factors enable arbuscular mycorrhiza symbiosis

Nature Communications, Год журнала: 2022, Номер 13(1)

Опубликована: Янв. 25, 2022

Abstract Arbuscular mycorrhiza (AM) is a widespread symbiosis between roots of the majority land plants and Glomeromycotina fungi. AM important for ecosystem health functioning as fungi critically support plant performance by providing essential mineral nutrients, particularly poorly accessible phosphate, in exchange organic carbon. colonize inside this promoted at low but inhibited high phosphate status, while mechanistic basis phosphate-dependence remained obscure. Here we demonstrate that major transcriptional regulator starvation responses rice PHOSPHATE STARVATION RESPONSE 2 (PHR2) regulates AM. Root colonization phr2 mutants drastically reduced, PHR2 required root colonization, mycorrhizal uptake, yield increase field soil. promotes targeting genes pre-contact signaling, function. Thus, directly wired to PHR2-controlled response.

Climate change is a defining challenge of the 21st century, and this decade critical time for action to mitigate worst effects on human populations ecosystems. Plant science can play an important role in developing crops with enhanced resilience harsh conditions (e.g. heat, drought, salt stress, flooding, disease outbreaks) engineering efficient carbon-capturing carbon-sequestering plants. Here, we present examples research being conducted these areas discuss challenges open questions as call plant community.

Innovation and appropriation in mycorrhizal and rhizobial Symbioses

The Plant Cell, Год журнала: 2022, Номер 34(5), С. 1573 - 1599

Опубликована: Фев. 3, 2022

Abstract Most land plants benefit from endosymbiotic interactions with mycorrhizal fungi, including legumes and some nonlegumes that also interact nitrogen (N)-fixing bacteria to form nodules. In addition these helpful interactions, are continuously exposed would-be pathogenic microbes: discriminating between friends foes is a major determinant of plant survival. Recent breakthroughs have revealed how key signals pathogens symbionts distinguished. Once this checkpoint has been passed compatible symbiont recognized, the coordinates sequential development two types specialized structures in host. The first serves mediate infection, second, which appears later, as sophisticated intracellular nutrient exchange interfaces. overlap both signaling pathways downstream infection components symbioses reflects their evolutionary relatedness common requirements interactions. However, different outputs symbioses, phosphate uptake versus N fixation, require fundamentally physical environments necessitated recruitment master regulators, NODULE INCEPTION-LIKE PROTEINS, PHOSPHATE STARVATION RESPONSES, for nodulation mycorrhization, respectively.

Soil phosphorus transformation and plant uptake driven by phosphate-solubilizing microorganisms

Frontiers in Microbiology, Год журнала: 2024, Номер 15

Опубликована: Март 27, 2024

Phosphorus (P) is an important nutrient for plants, and a lack of available P greatly limits plant growth development. Phosphate-solubilizing microorganisms (PSMs) significantly enhance the ability plants to absorb utilize P, which improving turnover yield. This article summarizes analyzes how PSMs promote absorption utilization nutrients by from four perspectives: types functions PSMs, phosphate-solubilizing mechanisms, main functional genes, impact complex inoculation on acquisition. reviews physiological molecular mechanisms phosphorus solubilization promotion with focus analyzing soil microbial communities its interaction root exudates. In order better understand their role in transformation provide prospects research promoting absorption. mainly activate insoluble through secretion organic acids, phosphatase production, mycorrhizal symbiosis, symbiosis indirectly activates via carbon exchange. can secrete acids produce phosphatase, plays crucial cycling, related genes are involved regulating P-solubilization ability. uptake great significance deeper understanding PSM-mediated utilization, efficiency agriculture.

Milestones in understanding transport, sensing, and signaling of the plant nutrient phosphorus

The Plant Cell, Год журнала: 2024, Номер 36(5), С. 1504 - 1523

Опубликована: Янв. 2, 2024

As an essential nutrient element, phosphorus (P) is primarily acquired and translocated as inorganic phosphate (Pi) by plant roots. Pi often sequestered in the soil becomes limited for growth. Plants have developed a sophisticated array of adaptive responses, termed P starvation to cope with deficiency improving its external acquisition internal utilization. Over past 2 3 decades, remarkable progress has been made toward understanding how plants sense respond changing environmental P. This review provides overview molecular mechanisms that regulate or coordinate emphasizing transport, sensing, signaling. We present major players regulators responsible uptake translocation. then introduce perceived at root tip, systemic signaling operated, which intracellular status sensed conveyed. Additionally, recent exciting findings about influence on plant-microbe interactions are highlighted. Finally, challenges prospects concerning interplay between other nutrients strategies enhance utilization efficiency discussed. Insights obtained from this knowledge may guide future research endeavors sustainable agriculture.
