More than 100 wild species of potato, with ploidies from 2x to 6x, grow in the Americas. These species are adapted to contrasting environments, showing wide phenotypic diversity in leaf, floral, and tuber morphology. The taxonomic relationship among species is not clear, mainly due to little chromosomal differentiation and pervasive interspecific hybridization. This review summarizes data from more than 20 years of studies on genetic and epigenetic variability of potato species, highlighting the importance of epigenetic variability, hybridization, and polyploidization in the evolution and diversification of this group. The epigenetic diversity of these species remains poorly characterized. This review addresses the ecological implications of epigenetic variation, emphasizing its role in plant adaptation to changing environments. Finally, the study proposes a model that integrates epigenetic variability into the evolution of natural potato populations, highlighting its potential for rapid adaptation and phenotypic differentiation.","PeriodicalId":220,"journal":{"name":"Plant Biology","volume":"27 3","pages":"325-332"},"PeriodicalIF":4.2,"publicationDate":"2025-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143522367","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nectar composition of plant species varies in relation to pollinator and can also be influenced by drought. We investigated both different pollinated species and the effects of drought in parallel. In addition, the influence of drought on nectar production and metabolism in nectaries should be investigated, since very little is currently known about this. The influence of drought stress on nectaries, nectar and leaves of 4 day- and night-flowering Nicotiana species (pollinated by sunbirds, hummingbirds, hawkmoths or bats) were investigated. The nectar volume, as well as metabolite concentrations (sugars, amino acids), inorganic ions and starch were measured. PCA and PERMANOVA were applied to determine the relative importance of different drought conditions on metabolism of nectaries and nectar. Drought stress led to changes in composition of nectaries and nectar in all four Nicotiana species. The day-flowering species had relatively similar changes, whereas the night-flowering species differed from these and also from each other. Quantities of sugars, amino acids and inorganic ions per flower decreased sharply in all Nicotiana species because of a strong decrease in nectar volume. Drought stress not only compromises plant growth but also nectar secretion and composition. These changes are likely to affect plant-pollinator interactions and may negatively impact successful pollination.","PeriodicalId":220,"journal":{"name":"Plant Biology","volume":" ","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-02-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143439445","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The perennial lifestyle is preponderant in nature. Arabis alpina is a perennial model organism with a particular architecture of branches having proximal perennial (PZ) and distal annual (AZ) stem zones with distinct anatomy and physiology. PZ undergoes secondary growth and stores carbon-rich macromolecules. Here, we investigated iron homeostasis in PZ versus AZ. We localized iron in stem internodes of PZ and AZ using Perls staining and ferritin immunodetection in the wild-type Pajares (Paj) and perpetual flowering 1 mutant. We mined transcriptome data of the developing PZ and AZ. Iron accumulated at various development stages in PZ and AZ. Iron levels in PZ were ca. two-fold higher than in AZ, irrespective of flowering. Iron was predominantly located within plastid-bound ferritin. Gene expression patterns supported the significance of ferritin and demonstrated enrichment of transcripts related to iron homeostasis within stems. Distinct patterns of expression among iron homeostasis genes were observed in relation to iron content in PZ and AZ, indicating tissue-specific regulatory mechanisms governing iron accumulation. Secondary growth in PZ plays a role in iron storage in the perennial A. alpina, while AZ may transiently store iron for seed production. Future research will address different iron homeostasis signalling pathways in AZ and PZ.","PeriodicalId":220,"journal":{"name":"Plant Biology","volume":" ","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-02-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143439449","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
