“…In addition to the three main bacterial phosphomonoesterases mentioned above, PAP‐like sequences were also found in genomes of 43 bacteria and four cyanobacteria species (Yeung et al ., 2009 ; Bhadouria and Giri, 2021 ). Based on homology models, bacterial PAPs are similar structurally to mammalian PAPs in the vicinity of their active sites (Schenk et al ., 2000).…”

Summary Critical to meeting cellular phosphorus (P) demand, soil bacteria deploy a number of strategies to overcome limitation in inorganic P (Pi) in soils. As a significant contributor to P recycling, soil bacteria secrete extracellular enzymes to degrade organic P (Po) in soils into the readily bioavailable Pi. In addition, several Po compounds can be transported directly via specific transporters and subsequently enter intracellular metabolic pathways. In this review, we highlight the strategies that soil bacteria employ to recycle Po from the soil environment. We discuss the diversity of extracellular phosphatases in soils, the selectivity of these enzymes towards various Po biomolecules and the influence of the soil environmental conditions on the enzyme's activities. Moreover, we outline the intracellular metabolic pathways for Po biosynthesis and transporter‐assisted Po and Pi uptake at different Pi availabilities. We further highlight the regulatory mechanisms that govern the production of phosphatases, the expression of Po transporters and the key metabolic changes in P metabolism in response to environmental Pi availability. Due to the depletion of natural resources for Pi, we propose future studies needed to leverage bacteria‐mediated P recycling from the large pools of Po in soils or organic wastes to benefit agricultural productivity.

“…AtPAP10 ( AT2G16430 ), the Arabidopsis homolog of braPAP10 , is a member of the purple acid phosphorylase (PAP) family ( Xie and Shang, 2018 ). PAPs are usually involved in the acquisition and distribution of phosphorus in plants, yet more functions of them have been revealed besides Pi deficiency adaption ( Bhadouria and Giri, 2021 ). Overexpression of AtPAP2 improved sucrose phosphate synthase (SPS) activity and the levels of sugars and tricarboxylic acid (TCA) metabolites, resulting in earlier bolting and higher seed yield ( Sun et al, 2012 ).…”

Male-sterile mutants are useful materials to study the anther and pollen development. Here, whole transcriptome sequencing was performed for inflorescences in three sterile lines of Chinese cabbage (Brassica campestris L. ssp. chinensis Makino, syn. B. rapa ssp. chinensis), the genic male-sterile line (A line), the Polima cytoplasmic male-sterile (CMS) line (P line), and the Ogura CMS line (O line) along with their maintainer line (B line). In total, 7,136 differentially expressed genes (DEGs), 361 differentially expressed long non-coding RNAs (lncRNAs) (DELs), 56 differentially expressed microRNAs (miRNAs) (DEMs) were selected out. Specific regulatory networks related to anther cell differentiation, meiosis cytokinesis, pollen wall formation, and tapetum development were constructed based on the abortion characteristics of male-sterile lines. Candidate genes and lncRNAs related to cell differentiation were identified in sporocyteless P line, sixteen of which were common to the DEGs in Arabidopsis spl/nzz mutant. Genes and lncRNAs concerning cell plate formation were selected in A line that is defected in meiosis cytokinesis. Also, the orthologs of pollen wall formation and tapetum development genes in Arabidopsis showed distinct expression patterns in the three different sterile lines. Among 361 DELs, 35 were predicted to interact with miRNAs, including 28 targets, 47 endogenous target mimics, and five precursors for miRNAs. Two lncRNAs were further proved to be functional precursors for bra-miR156 and bra-miR5718, respectively. Overexpression of bra-miR5718HG in B. campestris slowed down the growth of pollen tubes, caused shorter pollen tubes, and ultimately affected the seed set. Our study provides new insights into molecular regulation especially the ncRNA interaction during pollen development in Brassica crops.

“…Shallow root growth angle is beneficial in phosphorus uptake as phosphorus being immobile, stays in the upper layers of soil (Lynch & Brown, 2001). In addition to shallow root growth angle, an increase in root exudation of organic acids and acid phosphatases can increase available phosphate for uptake by root hairs and could act synergistically (Bhadouria & Giri, 2021; Gaviglio et al, 2019; Mehra et al, 2017; Panchal et al, 2021; Y.‐L.

Root hairs represent a beneficial agronomic trait to potentially reduce fertilizer and irrigation inputs. Over the past decades, research in the plant model Arabidopsis thaliana has provided insights into root hair development, the underlying genetic framework and the integration of environmental cues within this framework. Recent years have seen a paradigm shift, where studies are now highlighting conservation and diversification of root hair developmental programs in other plant species and the agronomic relevance of root hairs in a wider ecological context. In this review, we specifically discuss the molecular evolution of the RSL (RHD Six‐Like) pathway that controls root hair development and growth in land plants. We also discuss how root hairs contribute to plant performance as an active physiological rooting structure by performing resource acquisition, providing anchorage and constructing the rhizosphere with desirable physical, chemical and biological properties. Finally, we outline future research directions that can help achieve the potential of root hairs in developing sustainable agroecosystems.
