ABSTRACT.- Plants have evolved numerous traits to acquire phosphorus (P). Correspondingly, soil P availability modulates the functional composition of many plant communities. However, it is unclear to what extent plant species modulate the expression of different P-acquisition strategies (phenotypic plasticity). Moreover, how variation in soil-P availability interacts with plant phenotypic plasticity and species turnover to determine what P-acquisition strategies are present in highly diverse communities? To address these questions, we assessed associations between plant-available soil P and the magnitude of several P-acquisition traits in both individual species and plant communities in Campos grasslands. Root phosphatase activity (phosphomonoesterase and phosphodiesterase), leaf manganese (Mn) concentration (a proxy for carboxylate concentration in the rhizosphere) and arbuscular mycorrhizal (AM) colonization were assessed in 105, 52 and 54 native plant species, respectively, sampled across three to seven plant communities with contrasting concentrations of plant-available soil P. Furthermore, root diameter and plant cover of those species were also quantified. Variation in P-acquisition strategies among species was large: 157- and 118-fold for phosphatases, 96-fold for leaf [Mn] and 39-fold for AM colonization. Between half and two-thirds of the variation in community-weighted mean P-acquisition traits was accounted for by the interactive factors plant-available soil P, soil pH and root diameter. At low-P availability, phosphatases and carboxylate exudation (P-mining traits) and thin roots predominated, particularly at low soil pH. At higher P availability, AM associations (P-scavenging trait) and thicker roots were more common. Synthesis. Phenotypic plasticity was a major source of variation in the response of P-acquisition traits to soil properties, particularly for P-mining traits. Our results reveal that the plasticity of the expression of plant P-acquisition strategies in individual species was more important than changes in species presence or cover as a mechanism underlying shifts between P-mining and P-scavenging strategies as plant P availability varied across communities. © 2024 His Majesty the King in Right of Canada and The Author(s).

ABSTRACT.
Citrus fruits are highly consumed worldwide and represent one of the most important sources of ascorbic acid (AsA). However, information about the molecular mechanisms regulating AsA accumulation in Citrus fruit and the effects of environmental factors is scarce. In this study we have investigated the effect of fruit shading on AsA content and the expression of AsA biosynthetic, degrading and recycling genes in fruits of different Citrus species. Immature-green fruits were covered at the end of the cell enlargement phase and AsA concentration in the flavedo declined and remained at low levels as compared with light-exposed fruits. Fruit shading marginally altered the expression of genes from the l-galactose pathway and this effect was variable in the four Citrus species. However, specific isoforms (GalUR8 or GalUR12) from the l-galacturonic acid pathway were significantly repressed paralleling the reduction in AsA concentration. No significant effect of shading was detected in transcription of genes of the myo-inositol and l-gulose pathways as well as recycling and degradation. Collectively, results indicate that light avoidance inhibited accumulation of AsA in the flavedo of Citrus fruits and suggest that the l-galacturonic acid pathway has a relevant contribution to AsA content in this tissue. |
