This dual-isotope approach was used for isotope-signal deconvolution. We found evidence for metabolic processes affecting Δ<sub>1</sub>' and Δ<sub>3</sub>', which respond to air vapour pressure deficit (VPD), and processes affecting Δ<sub>1</sub>', Δ<sub>2</sub>', and ε<sub>met</sub>, which respond to precipitation but not VPD. These relationships exhibit change points dividing a period of homeostasis (1961-1980) from a period of metabolic adjustment (1983-1995). Homeostasis may result from sufficient groundwater availability. Additionally, we found Δ<sub>5</sub>' and Δ<sub>6</sub>' relationships with radiation and temperature, which are temporally stable and consistent with previously proposed isotope fractionation mechanisms. Based on the multitude of climate covariables, intramolecular carbon isotope analysis has a remarkable potential for climate reconstruction. While isotope fractionation beyond leaves is currently considered to be constant, we propose significant parts of the carbon and hydrogen isotope variation in tree-ring glucose originate in stems (precipitation-dependent signals).

Despite recent evidence for sink limitations to plant growth, there are reasons to be cautious about a sink-limited world view. First, source-limited vegetation models do a reasonable job at capturing geographic patterns in plant productivity and responses to resource limitations. Second, from an evolutionary perspective, it is nonadaptive for plants to invest in increasing carbon assimilation if growth is primarily sink-limited. In this review, we synthesize the potential evidence for and underlying physiology of sink limitation across terrestrial ecosystems and contrast mechanisms of sink limitation with those of source-limited productivity. We highlight evolutionary restrictions on the magnitude of sink limitation at the organismal level. We also detail where mechanisms regulating sink limitation at the organismal and ecosystem scale (e.g. the terrestrial carbon sink) diverge. Although we find that there is currently no direct evidence for widespread organismal sink limitation, we propose a series of follow-up growth chamber manipulations, systematized measurements, and modeling experiments targeted at diagnosing nonadaptive buildup of excess nonstructural carbohydrates that will help illuminate the prevalence and magnitude of organismal sink limitation.</p>","PeriodicalId":48887,"journal":{"name":"New Phytologist","volume":" ","pages":"966-981"},"PeriodicalIF":9.4,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142741007","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}

But the general effects of WGD are challenging to evaluate, in part due to the difficulty of directly comparing morphological patterns across disparate clades. We explored relationships between WGD and the evolution of reproductive complexity across vascular plants using a metric based on the number of reproductive part types. We used multiple regression models to evaluate the relative importance of inferred WGD events, genome size, and a suite of additional variables relating to growth habit and reproductive biology in explaining part type complexity. WGD was a consistent predictor of reproductive complexity only among angiosperms. Across vascular plants generally, reproductive biology, clade identity, and the presence of bisexual strobili (those that produce microsporangiate and megasporangiate organs) were better predictors of complexity. Angiosperms are unique among vascular plants in combining frequent polyploidy with high-reproductive complexity. Whether WGD is mechanistically linked to floral complexity is unclear, but we suggest widespread polyploidy and increased complexity were ultimately facilitated by the evolution of herbaceous growth habits in early angiosperms.</p>","PeriodicalId":48887,"journal":{"name":"New Phytologist","volume":" ","pages":""},"PeriodicalIF":9.4,"publicationDate":"2024-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142752070","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}

Unlike the NIa-Pro of most other potyviruses, the NIa-Pro of tobacco etch virus can also degrade DBP5 and trigger cell death, in both pepper and N. benthamiana. Furthermore, we discovered that the TuMV-encoded nuclear inclusion b can counteract NIa-Pro-induced cell death by co-opting DBP5.
