Phosphorus Acquisition and Utilization in Plants

Hans Lambers

Summary: Significant progress has been made on plant phosphorus nutrition at the molecular level, but there is a need to integrate information from various disciplines. Strategies to mobilize phosphorus in low-P soil are found to be more effective than mycorrhizal strategies. Understanding the trade-offs of different investment patterns in phosphorus fractions is crucial for optimizing plant growth.

Linking root exudation to belowground economic traits for resource acquisition

Zhihui Wen et al.

Summary: The concept of root exudation plays a crucial role in enhancing resource acquisition, yet remains a missing link in current research on root trait variation and belowground strategies. Incorporating root exudation into the structure of the root economics space is essential for a comprehensive understanding of soil nutrient acquisition. By integrating different root functional traits, a deeper understanding of the complexity of belowground resource-acquisition strategies can be achieved.

Organic anions facilitate the mobilization of soil organic phosphorus and its subsequent lability to phosphatases

Alan E. Richardson et al.

Summary: Organic anions can mobilize soil organic phosphorus, increasing its bioavailability. This has important implications for understanding phosphorus dynamics in natural and managed ecosystems, as well as improving phosphorus acquisition efficiency in agricultural plants.

Low soil phosphorus availability triggers maize growth stage specific rhizosphere processes leading to mineralization of organic P

Sunendra R. Joshi et al.

Summary: The study examines the influence of rhizosphere processes on organic P utilization in soil with low P-i availability and how these processes change with plant development. It was found that in low P soil, early stage plants showed P deficiency correlated with increased rhizosphere potential acid phosphatase activity, degradation of SOM and reduction in P-o pool; while late stage plants appeared to recover with decreased Meh (III) extractable P, increased microbial biomass C and P, change in microbial community structure, and higher TP in plant biomass.

A significant increase in rhizosheath carboxylates and greater specific root length in response to terminal drought is associated with greater relative phosphorus acquisition in chickpea

Manish Sharma et al.

Summary: The study investigated the effects of water stress under low phosphorus supply on P-acquisition by chickpea and identified a genotype with faster relative growth and P-acquisition rates. ICC 2884 genotype showed faster P-acquisition rate with greater specific root length, smaller mean root diameter, and increased rhizosheath carboxylates in response to water stress. It also maintained similar physiological P-use efficiency under water stress, making it recommended for chickpea breeding in low-P and terminal drought environments.

A chickpea genetic variation map based on the sequencing of 3,366 genomes

Rajeev K. Varshney et al.

Summary: By studying the genetic diversity of chickpea, the research team estimated the divergence of Cicer over the last 21 million years and identified chromosomal locations of deleterious mutations in elite germplasm. They also found targets for purging deleterious alleles through genomics-assisted breeding and proposed three crop breeding strategies.

Increasing nitrogen supply to phosphorus-deficient Medicago sativa decreases shoot growth and enhances root exudation of tartrate to discharge surplus carbon dependent on nitrogen form

Honghua He et al.

Summary: Nitrogen addition to P-deficient alfalfa decreased shoot growth and enhanced the release of tartrate, likely to discharge surplus carbon; and the effects varied with N form. Nitrogen addition weakened the positive effect of P addition on plant growth, and increased plant N and P concentrations, while P addition increased plant P concentration, but weakened the effect of N addition on plant N concentration. The amount of tartrate increased dramatically with increasing N rate, which decreased shoot growth, depending on N form.
