These processes include changes in land surface albedo, land-atmosphere carbon and water exchanges, forest productivity, and nutrient cycling (Fang <i>et al</i>., <span>2020</span>; Gerst <i>et al</i>., <span>2020</span>; Huang <i>et al</i>., <span>2023</span>). Additionally, spring phenology influences numerous biotic interactions, such as intra- and interspecies competition for resources and trophic interactions with other living organisms (Cohen & Satterfield, <span>2020</span>). Furthermore, vegetation-mediated climate feedback is impacted by spring phenology, as it can lead to earlier soil water depletion (Lian <i>et al</i>., <span>2020</span>) and an increased risk of summer droughts (Vitasse <i>et al</i>., <span>2021</span>; Li <i>et al</i>., <span>2023</span>). Despite the importance of spring phenology in ecological and Earth surface processes, our understanding of the drivers behind its variability across large vegetated landscapes and extended periods remains incomplete, creating considerable amounts of uncertainty when estimating how future climate change will affect spring phenology and other related biological processes (Geng <i>et al</i>., <span>2020</span>; Xie & Wilson, <span>2020</span>; Adams <i>et al</i>., <span>2021</span>).</p>\u0000<p>To better understand and represent the mechanisms underlying plant spring phenology in response to climate change, researchers have developed numerous prognostic models, such as growing degree day (GDD) models, sequential models, and parallel models (McMaster & Wilhelm, <span>1997</span>; Melaas <i>et al</i>., <span>2016</span>; Zhao <i>et al</i>., <span>2021</span>). These models incorporate key environmental indicators, such as temperature and photoperiod, to predict the leaf unfolding data (LUD) and other phenological timing (Chuine <i>et al</i>., <span>2000</span>, <span>2013</span>). The majority of these models attribute phenological shifts to chilling, that is, the exposure of plants to cold temperatures to break dormancy, forcing, which involves exposure to warm temperatures, and the photoperiod effect to promote growth (Heide, <span>2003</span>; Schwartz <i>et al</i>., <span>2006</span>). In addition to these models that only consider temperature and photoperiod, researchers recently have developed the eco-evolutionary optimality (OPT) theory and associated OPT-based spring phenology model as a more comprehensive and innovative hypothesis for spring phenology modeling (Fu <i>et al</i>., <span>2020</span>; Wang <i>et al</i>., <span>2020b</span>; Meng <i>et al</i>., <span>2021</span>). This theory posits that the LUD in plants results from trade-offs aimed at maximizing photosynthetic carbon gain and minimizing frost risk. This hypothesis was supported by Gu <i>et al</i>","PeriodicalId":214,"journal":{"name":"New Phytologist","volume":"16 1","pages":""},"PeriodicalIF":9.4,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143745690","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}

Despite there being theoretical support for LT crops, we suggest that there is insufficient empirical evidence to support the general acceptance of this theory. Our criticism focuses on two main points: the undervaluation of early season carbon assimilation and investment over the lifetime of the plant; and the overestimation of soil water savings. We argue that forgoing early season water use, and therefore also future investment in deeper and denser roots (improved resource acquisition), will negatively impact plant performance in many soil and climate contexts. Furthermore, we challenge the assumption that conserved soil water remains available for later use without loss, noting significant losses resulting from evaporation and other sinks. We advocate for a re-evaluation of LT traits, incorporating a balance of water and carbon dynamics throughout a plant's lifetime. We caution against the adoption of LT traits where they have not been empirically evaluated in the soils and climates of interest to individual research and breeding programs. We propose a more physiologically integrated approach to crop improvement, focusing on water extraction efficiency and strategic carbon investment.</p>","PeriodicalId":214,"journal":{"name":"New Phytologist","volume":"246 4","pages":"1439-1450"},"PeriodicalIF":8.3,"publicationDate":"2025-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/nph.70071","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143734424","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}
