Crop domestication increased photosynthetic phosphorus-use efficiency associated with changes in leaf phosphorus fractions under low soil phosphorus conditions
Background and aims
The domestication of modern crop cultivars involved significant changes in key agronomic traits relative to their wild relatives. This study aimed to investigate the effects of crop domestication on leaf phosphorus (P)-use strategies, particularly photosynthetic P-use efficiency (PPUE), under low plant-available soil P conditions.
Methods
Ten crop species and their wild relatives were grown in pots under low plant-available soil P conditions to compare leaf PPUE, the concentration and percentage of five leaf P fractions, and investigate the correlation of these P fractions with PPUE.
Results
Domesticated crops exhibited significantly higher area-based (Aarea) and mass-based (Amass) photosynthesis rate, and PPUE (63%, 74% and 69%, respectively) than their wild relatives under low plant-available P condition. Domesticated crops demonstrated a 49% higher metabolite-P concentration but an 18% lower lipid-P concentration than their wild relatives. Domestication significantly reduced P allocation to lipid-P (20%) and inorganic-P (9%), coupled with increased partitioning to metabolite-P (67%) and residual-P (43%). PPUE was positively correlated with Aarea, Amass, metabolite-P concentration, and the percentage of leaf P allocated to the metabolite-P fraction, while being negatively correlated with leaf P concentration, nucleic acid-P, inorganic-P concentration, and the percentage of leaf P allocated to inorganic-P fraction.
Conclusion
Crop domestication enhanced PPUE by increased photosynthesis rates and a shift in leaf P allocation to different P fractions. Greater allocation to P-containing metabolites but reduced investment in inorganic P provide crucial mechanistic insights for enhanced PPUE under P-limited condition, unravelling strategies aimed at improving crop P-use efficiency under low-limited environment.
期刊介绍：
Plant and Soil publishes original papers and review articles exploring the interface of plant biology and soil sciences, and that enhance our mechanistic understanding of plant-soil interactions. We focus on the interface of plant biology and soil sciences, and seek those manuscripts with a strong mechanistic component which develop and test hypotheses aimed at understanding underlying mechanisms of plant-soil interactions. Manuscripts can include both fundamental and applied aspects of mineral nutrition, plant water relations, symbiotic and pathogenic plant-microbe interactions, root anatomy and morphology, soil biology, ecology, agrochemistry and agrophysics, as long as they are hypothesis-driven and enhance our mechanistic understanding. Articles including a major molecular or modelling component also fall within the scope of the journal. All contributions appear in the English language, with consistent spelling, using either American or British English.
