“…(Libault et al, 2010;Wang et al, 2016). In this work, low P resulted in denser and longer root hairs which increased the absorption of N, K, Ca, Mg, and Fe, suggesting that P plays a significant role in root hair growth and a moderate deficiency of P can help to absorb other nutrients (Narang et al, 2000;Jungk, 2001;Huang et al, 2018;Kohli et al, 2020).…”

Walnut, an important non-wood product forest tree, has free root hairs in orchards. Root hairs are specialized cells originating from the root epidermis that are regulated by plant hormones, such as auxins. This study was conducted to evaluate the effect and mechanism of phosphorus stress on root hair growth of walnut (Juglans regia L.) seedings by auxin (IAA) biosynthesis and transport. Both low phosphorus (LP) and no phosphorus stresses (NP) heavily decreased plant height, leaf number, total root length, root surface, shoot and root biomass, and root nutrient contents. The LP treatment significantly increased root hair growth, accompanied with up-regulation of the positive regulation root hair growth gene JrCPC and down-regulation of the negative regulation root hair growth gene JrTTG1, while the NP treatment had opposite effects. The root IAA level, IAAO activities, IAA transport genes (JrAUX1, JrLAX1, and JrPIN1), and the biosynthesis genes (JrTAA1 and JrTAR1) were increased by the LP treatment, while the NP treatment decreased all of them. Interestingly, the auxin biosynthesis gene CsYUCCA1 was not affected, which suggested that P mainly affects root hair growth of walnut by regulating auxin transport, and then affects root nutrient absorption and plant growth.

“…associated with P-acquisition efficiency and P-use efficiency, and associated proxy traits. Many SNPs associated with roothair length in P-sufficient and P-deficient conditions have been reported recently (Kohli et al, 2020); here we report SNPs associated with PUE and P-acquisition efficiency related root traits as well as proxy traits, which can be deployed for breeding. As population structure is important for avoiding spurious associations, we identified three subpopulations using ADMIXTURE in the reference set (233 genotypes) and a smaller subset (91 genotypes).…”

Novel Genes and Genetic Loci Associated With Root Morphological Traits, Phosphorus-Acquisition Efficiency and Phosphorus-Use Efficiency in Chickpea

Chickpea—the second most important grain legume worldwide—is cultivated mainly on marginal soils. Phosphorus (P) deficiency often restricts chickpea yields. Understanding the genetics of traits encoding P-acquisition efficiency and P-use efficiency will help develop strategies to reduce P-fertilizer application. A genome-wide association mapping approach was used to determine loci and genes associated with root architecture, root traits associated with P-acquisition efficiency and P-use efficiency, and any associated proxy traits. Using three statistical models—a generalized linear model (GLM), a mixed linear model (MLM), and a fixed and random model circulating probability unification (FarmCPU) —10, 51, and 40 marker-trait associations (MTAs), respectively were identified. A single nucleotide polymorphism (SNP) locus (Ca1_12310101) on Ca1 associated with three traits, i.e., physiological P-use efficiency, shoot dry weight, and shoot P content was identified. Genes related to shoot P concentration (NAD kinase 2, dynamin-related protein 1C), physiological P-use efficiency (fasciclin-like arabinogalactan protein), specific root length (4-coumarate–CoA ligase 1) and manganese concentration in mature leaves (ABC1 family protein) were identified. The MTAs and novel genes identified in this study can be used to improve P-use efficiency in chickpea.

“…Even more, Wang et al (2016) considered that long and dense root hairs are important traits in ensuring efficient absorption of nutrients in the early establishment of plants in nutrient-limited soil and low nutrients input environment cropping systems. As an adaptive response to nutrient deficiency, an increase in root hair length and density enhances root-soil contact and the absorptive area for nutrient absorption (Kohli et al, 2020). For example, the Arabidopsis mutant has more and longer root hairs which are more efficient in acquiring phosphate from infertile soil environments (Huang et al, 2018;Narang et al, 2000).…”

“…For example, the Arabidopsis mutant has more and longer root hairs which are more efficient in acquiring phosphate from infertile soil environments (Huang et al, 2018;Narang et al, 2000).

“…Thus, N may have interactions with hormones, ROS, and calcium in regulating root hair growth. Phosphorus Phosphorus (P) is extremely immobile in the soil and plays a variety of essential roles in plants (Kohli et al, 2020). It is an important mineral nutrient in plants, not only as a constituent of key cellular molecules such as ATP, phospholipids, and nucleic acids, but also has a pivotal role in cellular signaling, energy conservation and metabolic regulation (Shin et al, 2005;Macdonald et al, 2011;Kohli et al, 2020).…”

Plant root hairs are cylindrical tubular projections from root epidermal cells. They increase the root surface area, which is important for the acquisition of water and nutrients, microbe interactions, and plant anchorage. The root hair specification, the effect of root hairs on nutrient acquisition and the mechanisms of nutrients (calcium, iron, magnesium, nitrogen, phosphorus, and potassium) that affect root hair development and growth were reviewed. The gene regulatory network on root hair specification in the plant kingdom was highlighted. More work is needed to clone the genes of additional root hair mutants and elucidate their roles, as well as undertaking reverse genetics and mutant complementation studies to add to the current knowledge of the signaling networks, which are involved in root hair development and growth regulated by nutrients.
