Conducted in the eastern Amazon, this is the only tropical forest experiment implementing precipitation exclusion continuously over decades, and at ‘ecosystem’ scale (the one-hectare area of forest was artificially droughted for 23 years). A loss of 34% of rainforest biomass was observed, which was primarily due to the mortality of large trees during the first 15 years of experimental drought. Biomass then stabilized from 2017 to 2023, attributed to the recovery of water availability per tree to levels observed in the control forest study area. The loss of large trees reduced water competition during this stabilization phase, shifting the ecosystem from a probable carbon source to a small biomass sink.</p><p>The researchers further monitored individual trees during the 2023–2024 growth seasons, which included pronounced wet and dry seasons influenced by the effects of global warming and the strong El Niño in 2023–2024.

Measurements of leaf water potential, relative water content and stem water content all indicated that the TFE trees that had survived the preceding multi-decadal drought had now achieved hydraulic homeostasis. This homeostasis was linked most strongly to ecosystem-level structural changes — reduced water demand and increased water availability resulting from the prior loss of large trees.</p>","PeriodicalId":18904,"journal":{"name":"Nature Plants","volume":"87 1","pages":""},"PeriodicalIF":18.0,"publicationDate":"2025-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144305380","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}

Efficient protein delivery is essential to modify biosynthetic processes in leucoplasts for human needs, but no effective transit peptide for leucoplasts is currently available. Here, using an in vitro leucoplast import system, we have identified six high-efficiency transit peptides. Compared with a widely used chloroplast transit peptide, these peptides delivered similar amounts of GFP into chloroplasts, but two to seven times more GFP into root and petal leucoplasts, attesting to the advantage of screening using leucoplasts. When used to deliver bacterial phytoene synthase (crtB) into rice calli and glyphosate-resistant EPSP synthase into <i>Arabidopsis</i>, these peptides enhanced carotenoid production and herbicide resistance, respectively. The correlation among levels of GFP delivery, carotenoid production and herbicide resistance indicates that the efficiency of these transit peptides is consistent across plant species and passenger proteins.

To address this, here we analysed global data on 330,087 angiosperm species, including 27,184 epiphytes, comparing range size and rarity between epiphytes and terrestrial plants. We calculated three range metrics, tested for differences across angiosperms and within epiphyte-rich families and used phylogenetic regressions to explore the role of epiphytism on species ranges. On average, epiphytes have larger ranges than closely related terrestrial species, supporting hypotheses that epiphytism promotes dispersal. However, small ranges are prevalent in epiphyte-rich families regardless of lifeform. Notably, about half of epiphyte species are rare, indicating greater vulnerability than terrestrials. Epiphyte rarity is attributable to evolutionary history and shared traits rather than epiphytism itself.</p>","PeriodicalId":18904,"journal":{"name":"Nature Plants","volume":"221 1","pages":""},"PeriodicalIF":18.0,"publicationDate":"2025-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144278662","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}
