As cold deacclimation rates increase with dormancy progression, the same amount of warming has greater damage risk the later it occurs in the season, depending on return of low temperatures.

{"title":"Ancestral duplication of MADS-box genes in land plants empowered the functional divergence between sporophytes and gametophytes","authors":"Yichun Qiu,&nbsp;Zhen Li,&nbsp;Claudia Köhler","doi":"10.1111/nph.20065","DOIUrl":"10.1111/nph.20065","url":null,"abstract":"&lt;p&gt;MADS-box transcription factors (TFs) have gained widespread recognition for their exceptional diversity and pivotal roles in various biological functions across eukaryotic organisms. Specifically, in land plants, the MADS-box gene family has undergone substantial expansion and provided the genetic raw material for many developmental novelties, including flowers, fruits and seeds. Therefore, understanding the origin of MADS-box genes is crucial for gaining insights into the evolutionary success of land plants. Land plant MADS-box TFs have been categorized into two groups. MIKC-type (Type II) TFs are named after the structural arrangement of the MADS (M), Intervening (I) and plant-specific Keratin-like (K) domain, followed by a variable C-terminal region. By contrast, M-type (Type I) TFs lack the K domain (Alvarez-Buylla &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2000&lt;/span&gt;; Kofuji &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2003&lt;/span&gt;; Nam &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2004&lt;/span&gt;). The identification of mutants exhibiting distinct flower organ patterns led to the discovery of a multitude of MIKC-type MADS-box TFs in plants (Ng &amp; Yanofsky, &lt;span&gt;2001&lt;/span&gt;; Nam &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2003&lt;/span&gt;; Kaufmann &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2005&lt;/span&gt;). By contrast, the identification of M-type genes occurred exclusively through bioinformatic analyses following the unveiling of the &lt;i&gt;Arabidopsis thaliana&lt;/i&gt; genome (Alvarez-Buylla &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2000&lt;/span&gt;). Within the MIKC-type of MADS-box TFs, the MIKC*-type is distinguished based on the different arrangements of exons that encode the K domain (Svensson &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2000&lt;/span&gt;; Henschel &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2002&lt;/span&gt;; Zobell &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2010&lt;/span&gt;; Kwantes &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2012&lt;/span&gt;; Rümpler &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2023&lt;/span&gt;). Both the ‘classic’ MIKC&lt;sup&gt;C&lt;/sup&gt;- and the MIKC*-types are present across land plant lineages and form well-supported separate clades (Kwantes &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2012&lt;/span&gt;; Gramzow &amp; Theissen, &lt;span&gt;2013&lt;/span&gt;; Liu &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2013&lt;/span&gt;), suggesting that they diverged before the diversification of land plant lineages (Henschel &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2002&lt;/span&gt;; Kofuji &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2003&lt;/span&gt;; Tanabe &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2005&lt;/span&gt;; Kwantes &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2012&lt;/span&gt;).&lt;/p&gt;&lt;p&gt;It was a long-standing prevailing view in the field that plant Type II genes are orthologs to myocyte enhancer factor-2 (MEF2) genes in animals. Those were presumed to have diverged from plant Type I genes and animal serum response factor (SRF) genes via an ancient duplication before the divergence of the extant eukaryotic lineages (Alvarez-Buylla &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2000&lt;/span&gt;). Thus, with the shared presence of the K domain, MIKC*-type MADS-box genes were intuitively considered more closely related to MIKC&lt;sup&gt;C&lt;/sup&gt;-type genes, collectively called Type II. This adheres to the principle of parsimony, by which the acquisition of the K domain should ideally have occurred only once during t","PeriodicalId":214,"journal":{"name":"New Phytologist","volume":"244 2","pages":"358-363"},"PeriodicalIF":8.3,"publicationDate":"2024-08-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/nph.20065","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141989268","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}
