Abstract:

Root phosphatase activity (RPA) is a key physiological trait that indicates plant phosphorus (P) acquisition ability, representing significant carbon investment and P gain. However, it is unclear how RPA is coordinated with key traits for nutrient acquisition. We analyzed a global dataset across 514 species from 83 studies to investigate how RPA is correlated with other key traits and its position within the global root economics space (RES) framework. We found that RPA exhibits significant coordination and trade-off with root morphological traits, yet remains independent of root branching and mycorrhizal colonization. Root nitrogen (N) and P concentrations were positively and negatively correlated with RPA, respectively. Moreover, we observed significantly higher RPA in N-fixers than in nonfixers, demonstrating the higher P-mining ability of N-fixers. Incorporating RPA into the classic RES, our findings support the multidimensional RES framework, showing a closer alignment of RPA with the acquisitive end of the conservation dimension. Our findings clarify how RPA is integrated into the global RES and contribute to an integrative understanding of plants' belowground strategies, with implications for plant form and ecosystem functioning.

Water and Mineral Acquisition

Water and Mineral Acquisition

Specialized tissues in plant roots have evolved to capture water, minerals, and some ions from the soil. Roots exhibit a variety of branching patterns that facilitate this process. The outermost root cells have specialized structures called root hairs that increase the root surface, thus increasing soil contact. Water can passively cross into roots, as the concentration of water in the soil is higher than that of the root tissue. Minerals, in contrast, are actively transported into root cells.

Morphogenesis

Morphogenesis

Plant morphogenesis—the development of a plant’s form and structure—involves several overlapping developmental processes, including growth and cell differentiation. Precursor cells differentiate into specific cell types, which are organized into the tissues and organ systems that make up the functional plant.

Cell Signaling in Plants

Cell Signaling in Plants

Plant cells communicate to coordinate their cycle of growth, flowering and fruiting, and activities in roots, shoots, and leaves in response to the changing environmental conditions. Plant signaling is distinct from animal signaling. Plants primarily utilize enzyme-linked receptors, whereas the largest class of cell-surface receptors in animals are G-protein coupled receptors (GPCRs). Unlike animals, receptor tyrosine kinases are rare in plants. Instead, plants have a diverse class of...
