Root microbiota of tea plants regulate nitrogen homeostasis and theanine synthesis to influence tea quality

Current Biology, Journal Year: 2024, Volume and Issue: 34(4), P. 868 - 880.e6

Published: Feb. 1, 2024

The flavor profile of tea is influenced not only by different varieties but also the surrounding soil environment. Recent studies have indicated regulatory role microbes residing in plant roots nutrient uptake and metabolism. However, impact this mechanism on quality remains unclear. In study, we showed that a consortium isolated from enhanced ammonia facilitated synthesis theanine, key determinant taste. Variations were observed composition microbial populations colonizing rhizosphere across seasons varieties. By comparing root microorganisms high-theanine variety Rougui with low-theanine Maoxie, identified specific group potentially modulate nitrogen metabolism, subsequently influencing theanine levels tea. Furthermore, constructed synthetic community (SynCom) mirroring microbe population found roots. Remarkably, applying SynCom resulted significant increase content plants imparted greater tolerance to deficiency Arabidopsis. Our study provides compelling evidence supporting use as functional fertilizers enhance quality.

ABSTRACT Plants depend heavily on efficient nutrient uptake and utilization for optimal growth development. However, plants are constantly subjected to a diverse array of biotic stresses, such as pathogen infections, insect pests, herbivory, well abiotic stress like drought, salinity, extreme temperatures, imbalances. These stresses significantly impact the plant's ability take up use it efficiency. Understanding how maintain efficiency under conditions is crucial improving crop resilience sustainability. This review explores recent advancements in elucidating mechanisms underlying conditions. Our aim offer comprehensive perspective that can guide breeding stress‐tolerant nutrition‐efficient varieties, ultimately contributing advancement sustainable agriculture.

Abstract Plant uptake and assimilation of essential nitrogen compounds from the soil are mainly in form nitrate ammonium ions. transporters (NRTs) play a crucial role into roots. NRT structural analysis reveals mechanisms by which these function. Similarly, plant (AMTs) mediate ions, their has provided valuable information on mechanisms. After roots, metabolism pathway involves incorporation organic compounds. Glutamine synthetase (GS) glutamate synthase (GoGAT) master players this pathway. They work together to convert ions glutamine glutamate, respectively. Different isoforms GS GoGAT exist, enabling plants fine-tune based environmental cues. Under severe abiotic stress conditions, nitric oxide (NO) been found enhance survival under drought. Furthermore, interaction between salinity availability studied, with NO identified as potential mediator responses salt stress. On other hand, excessive use fertilizers can lead health issues. Therefore, alternative strategies, such establishing fixation through diazotrophic microbiota, have explored reduce reliance synthetic fertilizers. Ultimately, genomics identify new genes related fixation, could be harnessed improve productivity. By deciphering genetic basis nitrogen-fixing traits, researchers aim develop crops that efficiently utilize environment.
