Plants utilize root exudates to balance the role of mineral nutrient transporters in recognizing the availability of nutrients and further the direct supply of nutrients depending on the demand. The root exudates are affected by fungal communities associated with the roots depending upon their abundance and composition.

Plant species growing in low-nutrient environments nutrient acquisition in the rhizosphere. However, also employ root exudates in ways other than as sym- periments involving the incubation of root border. biotic signals to soil microbes involved in nutrient with poorly soluble nutrient compounds are procurement.

Therefore, root exudate composition has been observed to differ between droughted, control, and recovering plants 11, 31. This suggests that different drought severity levels may also induce different shifts in root exudate concentration and composition, which may be linked to stress-induced shifts in C allocation and physiology.

Fe chlorosis is considered as one of the major constraints on crop growth and yield worldwide, being particularly worse when associated with S shortage, due to the tight link between Fe and S. Plant adaptation to inadequate nutrient availabilities often relies on the release of root exudates that enhance nutrients, mobilization from soil colloids and …

The primary role of roots are to support the plant and anchor the growth by absorption of mineral nutrient form the soil. Root performs several other important functions other than their primary role. One of the important functions of roots is secretion of organic compound in rhizosphere zone called root exudates.

Root exudates, as an important form of material input from plants to the soil, regulate the carbon input and efflux of plant rhizosphere soil and play an important role in maintaining the carbon and nutrient balance of the whole ecosystem. Root exudates are notoriously difficult to collect due to their underlying characteristics (e.g., low …

In a greenhouse study, we imposed three drought treatments (control, mild, severe) on blue grama (Bouteloua gracilis Kunth Lag. Ex Grifiths), and measured plant physiology and root exudate concentration and composition using GC–MS, NMR, and FTICR. With increasing drought severity, root exudate total C and organic C increased concurrently with ...

Root exudates are the product of photosynthesis and act as secondary metabolites. Root exudates have both positive and negative effect on plants depends on …

In this study, Stipa bungeana was analyzed, determined the composition and content of root exudates by GC–MS in a soil culture experiment and labeled with 13 CO 2 in a rhizibox experiment. Esters accounted for 65.38 % of root exudates, among which 1-propen-1, 2, 3-tricarboxylic acid-tributyl ester, and acetyl-tributyl citrate were the …

up most mineral nutrients through the rhizosphere where micro-organisms interact with plant products in root exudates. Plant root exudates consist of a complex mixture of organic acid anions, phytosiderophores, sugars, vitamins, amino acids, purines, nucleosides, inorganic ions (e.g. HC03 -, OH-, H+), gaseous molecules (C02,

The composition of root exudates is a main mechanism for selec-tive recruitment of microorganisms to the rhizosphere and adaptation to abioticstress conditions (Trivedi etal. 2020). Inmaize, thecompo-sition of root exudates differs between plant genotypes and in response to changes in the availability of nitrogen, P, potassium, and

Plant-induced changes in chemistry can lead to weathering of minerals (Uroz, Kelly, Turpault, Lepleux, & Frey-Klett, 2015) and alter the composition of microbial communities (Carson, Rooney, Gleeson, & Clipson, 2007). Further, root exudates can enhance root penetration of soils (Oleghe et al., 2017).
