Assigning ecological roles of fungi is essential to determine the role of individual taxa in nutrient cycling and forest ecology. The use of isotope natural abundances in forest ecosystems has been crucial in distinguishing fungi with two main modes of life: ectomycorrhizal and saprotrophic fungi (Henn &amp; Chapela, <span>2001</span>). Within saprotrophic fungi, isotope natural abundances further allow the identification of the substrates used (Kohzu <i>et al</i>., <span>1999</span>). Dual isotope analyses of the δ<sup>13</sup>C and δ<sup>15</sup>N values consistently indicate a differentiation in isotopic signatures between ectomycorrhizal and saprotrophic fungi within and among ecosystems (Henn &amp; Chapela, <span>2001</span>; Taylor <i>et al</i>., <span>2003</span>; Trudell <i>et al</i>., <span>2004</span>; Mayor <i>et al</i>., <span>2009</span>). These signatures have been shown to reflect the ecophysiology of fungi and demonstrate that fungi that can utilize organic nitrogen exhibit higher δ<sup>15</sup>N than those fungi restricted to mineral nitrogen sources (Gebauer &amp; Taylor, <span>1999</span>; Lilleskov <i>et al</i>., <span>2002</span>). Still, the ability to distinguish fungal nutritional modes has been long restricted to fungi that produce macroscopic sporocarps, such as mushrooms, due to their large mass which allows for physical measurements. Thus, for many fungi, particularly those associated with plant roots that do not form evident fruiting bodies, isotope natural abundances of fungal hyphae are scarce.</p><p>Besides ectomycorrhizal fungi, isotope natural abundances are known for sporocarp-forming ericoid (e.g. Hobbie &amp; Hogberg, <span>2012</span>) and orchid-associated nonrhizoctonia saprotrophic fungi (e.g. Ogura-Tsujita <i>et al</i>., <span>2009</span>). Yet, values of δ<sup>13</sup>C and δ<sup>15</sup>N are poorly known for arbuscular mycorrhizal fungi (but see e.g. Courty <i>et al</i>., <span>2011</span>; Suetsugu <i>et al</i>., <span>2020</span>, for isotope values of fungal spores), and the orchid-associated fungi known as ‘rhizoctonia’ in natural conditions. Recently, Klink <i>et al</i>. (<span>2020</span>) obtained the δ<sup>13</sup>C and δ<sup>15</sup>N of arbuscular mycorrhizal hyphae isolated from roots of a grass and a legume, inoculated in experimental conditions, thereby providing an efficient method to extract hyphae from roots. Using this method with a few modifications, here, we measured the isotope natural abundances δ<sup>13</sup>C and δ<sup>15</sup>N of naturally occurring arbuscular mycorrhizal (Fig. 1a–c) and orchid-associated hyphae (Fig. 1d–f) directl","PeriodicalId":48887,"journal":{"name":"New Phytologist","volume":"239 4","pages":"1166-1172"},"PeriodicalIF":9.4,"publicationDate":"2023-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/nph.18990","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"5762231","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 is generally accepted that all angiosperm species have experienced at least one polyploidization event in their evolutionary past (Jiao <i>et al</i>., <span>2011</span>). Therefore, most (if not all) plant species should be considered as paleo-polyploids that have since diploidized to some extent. As such, the distinction between diploids and polyploids should be made with respect to a reference timepoint. In recent decades, polyploid research has experienced a resurgence among plant evolutionary biologists. This is largely due to the use of genomic analyses that have revealed a rich history of genome duplications across multiple plant lineages. Indeed, numerous studies have investigated the impact of polyploidy on morphological and life-history traits, ecology, diversification patterns, and genome evolution (reviewed in Soltis &amp; Soltis, <span>2000</span>; Otto &amp; Whitton, <span>2003</span>; Ramsey &amp; Schemske, <span>2003</span>; Otto, <span>2007</span>; Ramsey &amp; Ramsey, <span>2014</span>; Wendel, <span>2015</span>; Soltis <i>et al</i>., <span>2016</span>; Van de Peer <i>et al</i>., <span>2017</span>; Fox <i>et al</i>., <span>2020</span>). Notably, many of these studies focus on the effect of polyploidy in the context of a specific taxonomic group, which limits our ability to draw conclusions regarding the universal consequences of polyploidy, and to distinguish broad convergent trends from species-specific idiosyncrasies. There is thus a growing need to expand the examination of ploidy estimates across the seed plants clade, to obtain robust and broad information about the effect of polyploidy.</p><p>In the last few years, multiple methods for ploidy inferences based on sequenced genomic data have been developed (e.g. Jiao <i>et al</i>., <span>2011</span>; Rabier <i>et al</i>., <span>2014</span>; Vanneste <i>et al</i>., <span>2014</span>; Tiley <i>et al</i>., <span>2018</span>; Zwaenepoel &amp; Van de Peer, <span>2020</span>). However, due to the computational complexities and substantial amount of genomic data involved, the applications of such methods are still somewhat limited and are usually applied at phylogenetic scales above the species level, for example, by sampling representatives from several clades of interest. As such, the most comprehensive sequence-based analysis to date, which was conducted by the 1KP initiative and encompassed the transcriptomes of roughly 1100 plant species, has identified 244 whole-genome duplication (WGD) events occurring within Viridiplantae (One Thousand Plant Transcriptomes Initiative, <span>2019</span>; Li &amp; Barker, <span>2020</span>).</p><p>Ploidy estimation at the species level is still largely based on information derived from chromosome numbers.

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.
