{"title":"An ice-binding protein from the glacier ice alga Ancylonema nordenskioeldii","authors":"James A. Raymond,&nbsp;Lenka Procházková,&nbsp;Daniel Remias,&nbsp;Linda Nedbalová","doi":"10.1111/nph.70049","DOIUrl":"10.1111/nph.70049","url":null,"abstract":"&lt;p&gt;As plants began to colonize the land &lt;i&gt;c&lt;/i&gt;. 470–450 million years ago, they had to overcome many abiotic stresses not experienced by their marine ancestors (Rensing, &lt;span&gt;2018&lt;/span&gt;). One such stress was freezing and thawing, which can damage plant cell walls. Bacteria, which had established their presence on land well before the arrival of plants, greatly aided the transition of plants to land by the horizontal transfer of key genes (Yue &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2012&lt;/span&gt;; Ma &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2020&lt;/span&gt;). Bacteria are likely donors of genes that can mitigate freeze–thaw injury, as proteins with ice-binding activity have been found in several bacteria (Raymond &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2007&lt;/span&gt;, &lt;span&gt;2008&lt;/span&gt;; Vance &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2018&lt;/span&gt;). Each of the proteins in those studies contains a &lt;i&gt;c&lt;/i&gt;. 200-aa domain called DUF3494 that has a beta solenoid structure with one side that binds to ice crystals (Vance &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2019&lt;/span&gt;). At very low concentrations, these proteins can drastically prevent the recrystallization of ice that occurs during thawing, which is thought to damage cell walls. Similar proteins have been identified in hundreds of species of bacteria, although not all of them have been examined for ice-binding activity. Horizontally acquired genes of this type appear to be the source of freeze–thaw tolerance in a number of algae and fungi that live in icy habitats (Raymond &amp; Kim, &lt;span&gt;2012&lt;/span&gt;).&lt;/p&gt;&lt;p&gt;Zygnematophyceae, being the closest known relatives of all land plants (Cheng &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2019&lt;/span&gt;), are of interest because of their remarkable ability to find solutions for the stresses encountered by early land plants (Kunz &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2024&lt;/span&gt;). In this vein, Bowles &lt;i&gt;et al&lt;/i&gt;. (&lt;span&gt;2024&lt;/span&gt;) recently obtained the metagenome of algae inhabiting the Morteratsch Glacier in Switzerland to investigate the adaptation of the early streptophyte alga &lt;i&gt;Ancylonema nordenskioeldii&lt;/i&gt; to life in ice. Among the survival mechanisms investigated, the authors looked for genes encoding ice-binding proteins (IBPs). They found several candidates in the protein kinase superfamily, ATP-binding cassette protein family and heat shock protein family, although none were confirmed to have ice-binding activity. Apparently, they did not see our earlier paper in which we identified an IBP in &lt;i&gt;A. nordenskioeldii&lt;/i&gt; (&lt;i&gt;An&lt;/i&gt;IBP) from the Morteratsch Glacier (Procházková &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2024&lt;/span&gt;). Here, we summarize the main findings of this paper, in which we showed that &lt;i&gt;An&lt;/i&gt;IBP has ice-binding activity and that this activity could be attributed to a protein of the DUF3494 family.&lt;/p&gt;&lt;p&gt;The &lt;i&gt;Ancylonema&lt;/i&gt; species &lt;i&gt;A&lt;/i&gt;. &lt;i&gt;nordenskioeldii&lt;/i&gt; and &lt;i&gt;A. alaskanum&lt;/i&gt; dominate the algae on Morteratsch Glacier, although their relative abundances can vary drastically from year to year (Procházková &lt;i&gt;et al.&lt;/i&gt;, &lt;span&gt;2024&lt;/span&gt;).

Reviving a tradition initiated by Sir Arthur Tansley (&lt;span&gt;1931&lt;/span&gt;), the founding Editor of &lt;i&gt;New Phytologist&lt;/i&gt;, I will use the opportunity of a Valedictory Editorial to indulge in some crystal ball gazing concerning future challenges and opportunities for the journal.&lt;/p&gt;&lt;p&gt;However, before doing this it is worth reminding ourselves of the debt we owe to Tansley and why his legacy is important in the context of our mission to promote plant science and serve the international community of plant scientists. In contrast to most other plant science journals, &lt;i&gt;New Phytologist&lt;/i&gt; is neither owned by a learned society nor by a commercial publisher. Instead, it is wholly owned by the not-for-profit New Phytologist Foundation (https://www.newphytologist.org/). This is important because it means that we are independent. We are neither required to satisfy the expectations of shareholders, nor are we in thrall to a membership whose focus may reflect a geographical location or specific botanical interests. It also means that, when opportunities arise, we can be light on our feet. As a not-for-profit organization, we use the surplus income that we earn from publishing &lt;i&gt;New Phytologist&lt;/i&gt; to support early career researchers through the award of prizes, such as the Tansley Medal (https://www.newphytologist.org/awards/tansleymedal) and bursaries to facilitate their attendance and participation in our Next Generation Scientists (NGS) meetings (https://www.newphytologist.org/nextgenevents). In addition, the income allows us to stage New Phytologist Symposia, such as the recent 46&lt;sup&gt;th&lt;/sup&gt; Symposium on Stomata, held in Kaifeng, China (https://www.newphytologist.org/symposia/46), and workshops (for a list of recent workshops, see https://www.newphytologist.org/workshops).&lt;/p&gt;&lt;p&gt;In 2012, when Keith Lindsey succeeded Ian Alexander as Chair of the Board of Trustees and I followed Ian Woodward as Editor-in-Chief of &lt;i&gt;New Phytologist&lt;/i&gt;, we published an Editorial in which we discussed the challenges and opportunities facing the journal (Hetherington &amp; Lindsey, &lt;span&gt;2012&lt;/span&gt;). At that time, although open access (OA) and the impact of new technology on publishing were uppermost in our thoughts, I do not think that either of us predicted the seismic changes to publishing brought about by the former, while artificial intelligence (AI) was not on our radar. Both can be regarded as disruptive innovations. Of the two, OA is the more mature and it has been adopted with enthusiasm by research funders in some jurisdictions.&lt;/p&gt;&lt;p&gt;The arguments in support of the OA model of publishing are laudable and have been well rehearsed. At the core is the rightful goal to bring the results of research endeavour to the widest possible audience at no cost to the reader. In this sense, OA achieves its objectives.

Cooper, Sacha J. Mooney, Malcolm J. Hawkesford, W. Richard Whalley","doi":"10.1111/nph.70013","DOIUrl":"https://doi.org/10.1111/nph.70013","url":null,"abstract":"&lt;h2&gt; Introduction&lt;/h2&gt;\u0000&lt;p&gt;With drought occurrences projected to increase due to climate change, breeding crops tolerant to water stress has become crucial to sustaining crop yields and meeting the growing demand for food (Davies &amp; Bennett, &lt;span&gt;2015&lt;/span&gt;). Among various techniques, developing cultivars with deep roots and improved rhizosphere has been proposed as a potential solution to address this challenge (Lynch, &lt;span&gt;2013&lt;/span&gt;, &lt;span&gt;2019&lt;/span&gt;; Gao &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2016&lt;/span&gt;; Rabbi &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2018&lt;/span&gt;; Hallett &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2022&lt;/span&gt;). However, root water uptake depends not only on root architecture and its rhizosphere (Zhu &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2024&lt;/span&gt;), but also on other abiotic and biotic factors (Vadez, &lt;span&gt;2014&lt;/span&gt;; Q. Sun &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2021&lt;/span&gt;). Phenotyping root morphology and analysing the rhizosphere alone is thus insufficient to determine the water use efficiency of plants, and understanding the response of other root traits to environmental changes is also important (Vadez, &lt;span&gt;2014&lt;/span&gt;). In fact, experimental observations have shown that not all plants with deep roots increased their water uptake from the deep soil when the topsoil dried (Prechsl &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2015&lt;/span&gt;; Rasmussen &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2020&lt;/span&gt;; Gessler &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2022&lt;/span&gt;; Deseano Diaz &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2023&lt;/span&gt;), and a recent meta-analysis showed that root depth does not necessarily equate to root water uptake depth (Bachofen &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2024&lt;/span&gt;). These suggest the existence of additional mechanisms that regulate root water uptake from different soil layers (Kulmatiski &amp; Beard, &lt;span&gt;2013&lt;/span&gt;).&lt;/p&gt;\u0000&lt;p&gt;Water ascent in plants is driven by a water potential gradient between soil and leaves. Plants regulate this process by modifying their hydraulic conductance in different organs (Bartlett &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2016&lt;/span&gt;). In the aboveground, plants cope with water stress by stomatal closure (Hopmans &amp; Bristow, &lt;span&gt;2002&lt;/span&gt;; Carminati &amp; Javaux, &lt;span&gt;2020&lt;/span&gt;; Corso &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2020&lt;/span&gt;), and xylem embolisation (Loepfe &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2007&lt;/span&gt;; Bartlett &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2016&lt;/span&gt;; Scoffoni &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2017&lt;/span&gt;; Gao &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2020&lt;/span&gt;), while the strategies plants use to extract water from different soil layers in the field remain elusive (Kühnhammer &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2020&lt;/span&gt;). Root water uptake involves two distinct yet interconnected processes: radial water flow from the rhizosphere into root xylem vessels, and axial water flow through the xylem vessels (Vadez, &lt;span&gt;2014&lt;/span&gt;). Compared to axial water flow, the pathways through which water moves from the rhizosphere into the xylem are multiple and complicated (Steudle &amp; Peterson, &lt;span&gt;1998&lt;/span&gt;; Johnson &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2014&lt;/span&gt;; Domec &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2021&lt;/span&gt;).
