This provides an exceptional opportunity for long-term and taxonomically highly resolved vegetation reconstructions to be made across the Late Pleistocene and Holocene for southern California.

Xavier Picó, Thomas Bataillon, Camilla Lind Salomonsen, Marianne Glasius, Bodil K. Ehlers","doi":"10.1111/nph.20314","DOIUrl":"https://doi.org/10.1111/nph.20314","url":null,"abstract":"&lt;h2&gt; Introduction&lt;/h2&gt;\u0000&lt;p&gt;Plant root exudates encompass a vast array of primary (e.g. carbohydrates, amino acids, and organic acids) and secondary metabolites (e.g. flavonoids, terpenoids, and alkaloids) that shape the physical, chemical, and biological properties of the soil (Oburger &amp; Jones, &lt;span&gt;2018&lt;/span&gt;). They also facilitate nutrient cycling and mediate biotic interactions in the rhizosphere, thereby fostering a healthy soil ecosystem (Badri &amp; Vivanco, &lt;span&gt;2009&lt;/span&gt;; Rasmann &amp; Hiltpold, &lt;span&gt;2022&lt;/span&gt;). Despite the ecological relevance of root exudates, several factors, such as stress and developmental status, influence their chemical composition and challenge their quantification. For instance, stress by elevated phosphorus increases pthalic acid in &lt;i&gt;Cyperus alternifolius&lt;/i&gt; (Duan &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2020&lt;/span&gt;), hydric stress induces various organic acids in &lt;i&gt;Zea mays&lt;/i&gt; (Song &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2012&lt;/span&gt;), and pathogen infection in &lt;i&gt;Arabidopsis thaliana&lt;/i&gt; stimulates long-chain fatty acids and amino acids that recruit protective &lt;i&gt;Pseudomonas&lt;/i&gt; species (Wen &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2021&lt;/span&gt;). Furthermore, development also affects exudate profiles in &lt;i&gt;A. thaliana&lt;/i&gt; with sugar alcohols decreasing and amino acids increasing over time in early developmental stages (Chaparro &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2013&lt;/span&gt;), whereas young fir trees exudate more carbohydrates and quercetin than older trees, which secrete more lipids and salicylic acids, shifting from nutrient acquisition to defense over-development (Chen &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2023&lt;/span&gt;). Given the influence of root exudates on plant–environment interactions and adaptive strategies (Novoplansky, &lt;span&gt;2019&lt;/span&gt;; Williams &amp; de Vries, &lt;span&gt;2020&lt;/span&gt;; Subrahmaniam &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2023&lt;/span&gt;), unraveling the chemistry of root exudates may help decipher the complexity of plant metabolism but also the ecology of plant communities (Mommer &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2016&lt;/span&gt;; van Dam &amp; Bouwmeester, &lt;span&gt;2017&lt;/span&gt;; McLaughlin &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2023&lt;/span&gt;).&lt;/p&gt;\u0000&lt;p&gt;However, our knowledge of natural variation in root exudate composition is rather scarce (Vives-Peris &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2020&lt;/span&gt;; Escolà Casas &amp; Matamoros, &lt;span&gt;2021&lt;/span&gt;; Wang &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2021&lt;/span&gt;). This is a problem because understanding natural variation in plant traits is of paramount importance in different disciplines, as natural variation reflects long-term evolutionary dynamics, can reveal environmental factors driving this variation, and facilitates the exploration of the genetic basis of trait differences (Mitchell-Olds &amp; Schmitt, &lt;span&gt;2006&lt;/span&gt;; Alonso-Blanco &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2009&lt;/span&gt;). One reason for the scarcity of studies on natural variation in plant root exudates has to do with the technical challenges for capturing and analyzing the complex chemical data from root exudates (van Dam &amp; Bouwmeester, &lt;span&gt;2017&lt;/span&gt;; Obu","PeriodicalId":214,"journal":{"name":"New Phytologist","volume":"19 1","pages":""},"PeriodicalIF":9.4,"publicationDate":"2024-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142804806","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
