In this study, changes in plant growth, biomass allocation, and P use efficiency (PUE) of Chinese fir in different P environments were analyzed by FPA and root P application (RPA) treatments. The effects of FPA on P-foraging behavior of Chinese fir root system in P-deficient environment were then discussed. The root biomass with RPA was more significant at 0.03–0.25 mmol·L⁻¹ P concentrations than that with FPA; however, the PUE was significantly reduced by 28.89–29.41 %. With an increase in the P application concentration, under the effect of FPA, the Chinese fir roots mainly reduced root proliferation by decreasing the tip number, surface area and volume but increasing in diameter, as well as the PUE of root, aboveground. As a result, the entire plant was improved. However, the degree of morphological adjustment of the root system was lower than that under RPA. In summary, both FPA and RPA can alleviate P starvation in Chinese fir to a certain extent, thereby improving PUE. Compared with RPA, FPA had a more significant impact on the behavior of Chinese fir roots in sensing and responding to soil P content, and the roots could more quickly sense changes in P content in the body. This mechanism provides valuable insights into the root response strategies of plants in P-deficient environments.</div></div>","PeriodicalId":11758,"journal":{"name":"Environmental and Experimental Botany","volume":"228 ","pages":"Article 106004"},"PeriodicalIF":4.5,"publicationDate":"2024-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142535454","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, the seedling height, root length, plant fresh weight, total root surface area, and total root volume of <em>Tritipyrum</em> ‘Y1805’ increased significantly under salt-stress and recovery conditions. The plant water content showed limited changes under salt stress. The cytokinin, amino acid, soluble protein, and pyruvate contents, as well as the peroxidase activity, increased under salt stress and decreased quickly after recovery. The MDA content and electrical conductivity increased after 5 h of salt stress, but they returned rapidly to the control level afterwards. ‘Y1805’ had strong salt tolerance and could adapt quickly to salt-stress conditions. An assay of transposase-accessible chromatin with sequencing (ATAC-seq) indicated that most peaks were located in the distal intergenic regions under salt-stress and control conditions. We found 85 motifs in the 1776 location-specific peaks and 478 motifs in altered signal peaks under salt stress. The transcription factors binding to these motifs belonged mainly to the MYB family, followed by the AP2/EREBP, bZIP, bHLH, and WRKY families. The main Gene Ontology terms organic acid catabolic process, carboxylic acid catabolic process, cellular hormone metabolic process, cytokinin metabolic process, and cellular amino acid catabolic process were significantly enriched based on the associated differentially expressed genes between ATAC-seq and transcriptomics.

Sampling followed a hierarchical approach to assess trait genetic variation within and among four distinct geographical regions. We found high but similar plastic responses across populations, which were consistent with adaptive plasticity to drought, including advanced phenology, more sclerophyllous leaves, higher water use efficiency and larger seeds in dry conditions. Despite these generally similar plastic responses, we found significant population differentiation in quantitative traits, part of which was structured at the regional scale. Such differentiation was not associated with environmental variation, including differences in climate and soil conditions. This suggests that non-adaptive processes might have had a role on genetic differentiation in <em>H. squamatum</em>, likely due to the island-like configuration of gypsum habitats and the lack of effective seed dispersal of the study species.

In addition, TH decreased the osmotic stress, improved water potential and increased water use efficiency in tomato plants, whereas the integrity of gas exchange parameters were maintained; as a consequence, an increase in tomato yield was achieved. Moreover, the ratio of stress hormones (ABA, SA and JA) to growth regulating hormones (GA, auxins and cytokinins) decreased under TH. Metabolomic analysis showed clear defined patterns of differentially accumulated metabolites. Some of the metabolites with higher abundance in TH were linked to phenylpropanoid biosynthesis and phenylalanine metabolism, whereas alanine, aspartate and glutamate metabolism, monoterpenoid biosynthesis and butanoate metabolism pathways were downregulated.

These stresses, driven by climate change, soil degradation, and pollution, disrupt water and nutrient uptake, photosynthesis, and cellular integrity. Consequently, plant growth, production, and yield are significantly reduced, highlighting the need for sustainable techniques, like utilizing soil microbes, which is crucial for effectively alleviating abiotic stress in plants. Microbial inoculation, particularly with arbuscular mycorrhizal fungi (AMF) and plant growth-promoting bacteria (PGPB), significantly mitigates these stresses. These microorganisms enhance plant growth, nutrient uptake, and stress tolerance through mechanisms like nutrient solubilization, polyamine accumulation, and reactive oxygen species (ROS) scavenging. They improve plant physiological responses, such as photosynthesis rates and stomatal conductance, and contribute to ultrastructural stability by maintaining membrane integrity and promoting the accumulation of osmolytes like trehalose, proline, polyamines (PA), and glycine betaine (GB). The activation of antioxidant enzymes viz. superoxide dismutase (SOD), catalase (CAT), and ascorbate peroxidase (APX) further reduces oxidative stress. Key signaling pathways, including the Mitogen-Activated Protein Kinase (MAPK) cascade and Salt Overly Sensitive (SOS) signaling, play critical roles in plant responses to osmotic and ionic stresses.
