However, there is considerable uncertainty concerning what drought adjustment is and whether plants can adjust to sustained drought. This review focuses on woody plants and synthesises the evidence for drought adjustment in a selection of key above-ground and below-ground plant traits. We assess whether evaluating the drought adjustment of single traits, or selections of traits that operate on the same plant functional axis (e.g. photosynthetic traits) is sufficient, or whether a multi-trait approach, integrating across multiple axes, is required. We conclude that studies on drought adjustments in woody plants might overestimate the capacity for adjustment to drier environments if spatial studies along gradients are used, without complementary experimental approaches. We provide evidence that drought adjustment is common in above-ground and below-ground traits; however, whether this is adaptive and sufficient to respond to future droughts remains uncertain for most species. To address this uncertainty, we must move towards studying trait integration within and across multiple axes of plant function (e.g. above-ground and below-ground) to gain a holistic view of drought adjustments at the whole-plant scale and how these influence plant survival.","PeriodicalId":48887,"journal":{"name":"New Phytologist","volume":"239 4","pages":"1173-1189"},"PeriodicalIF":9.4,"publicationDate":"2023-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/nph.19000","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"5821237","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It refers to the strategy of some plants to persist and even thrive in environments with low light levels because of the shade produced by the vegetation proximity (e.g. in the understory). Shade tolerance influences the organization, structure, functioning, and dynamics of plant communities. However, little is known about its molecular and genetic basis. By contrast, there is a good understanding on how plants deal with the proximity of other plants, a divergent strategy used by most crops to respond to vegetation proximity. While generally shade-avoiding species strongly elongate in response to the proximity of other plants, shade-tolerant species do not. Here we review the molecular mechanisms that control the regulation of hypocotyl elongation in shade-avoiding species as a reference framework to understand shade tolerance. Comparative studies indicate that shade tolerance is implemented by components also known to regulate hypocotyl elongation in shade-avoiding species. These components, however, show differential molecular properties that explain how, in response to the same stimulus, shade-avoiding species elongate while shade-tolerant ones do not.","PeriodicalId":48887,"journal":{"name":"New Phytologist","volume":"239 4","pages":"1190-1202"},"PeriodicalIF":9.4,"publicationDate":"2023-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/nph.19047","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"6003318","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
