A trait-based framework for seagrass ecology: trends and prospects
Moreira-Saporiti, Agustín; Teichberg, Mirta; Garnier, Eric; Cornelissen, J. Hans C.; Alcoverro, Teresa; Björk, Mats; Boström, ChristofferIn the last three decades, quantitative approaches that rely on organism traits instead of taxonomy have advanced different fields of ecological research through establishing the mechanistic links between environmental drivers, functional traits, and ecosystem functions. A research subfield where trait-based approaches have been frequently used but poorly synthesized is the ecology of seagrasses; marine angiosp...
2b-RAD genotyping of the seagrass Cymodocea nodosa along a latitudinal cline id...
Ruocco, Miriam; Jahnke, Marlene; Silva, João; Procaccini, Gabriele; Dattolo, EmanuelaPlant populations distributed along broad latitudinal gradients often show patterns of clinal variation in genotype and phenotype. Differences in photoperiod and temperature cues across latitudes influence major phenological events, such as timing of flowering or seed dormancy. Here, we used an array of 4,941 SNPs derived from 2b-RAD genotyping to characterize population differentiation and levels of genetic an...
Daily regulation of key metabolic pathways in two seagrasses under natural ligh...
Ruocco, Miriam; Barrote, Isabel; Hofman, Jan Dirk; Pes, Katia; Costa, Monya; Procaccini, Gabriele; Silva, João; Dattolo, EmanuelaThe circadian clock is an endogenous time-keeping mechanism that enables organisms to adapt to external environmental cycles. It produces rhythms of plant metabolism and physiology, and interacts with signaling pathways controlling daily and seasonal environmental responses through gene expression regulation. Downstream metabolic outputs, such as photosynthesis and sugar metabolism, besides being affected by th...
m6A RNA Methylation in marine plants: first insights and relevance for biologic...
Ruocco, Miriam; Ambrosino, Luca; Jahnke, Marlene; Chiusano, Maria; Barrote, Isabel; Procaccini, Gabriele; Silva, João; Dattolo, EmanuelaCircadian regulations are essential for enabling organisms to synchronize physiology with environmental light-dark cycles. Post-transcriptional RNA modifications still represent an understudied level of gene expression regulation in plants, although they could play crucial roles in environmental adaptation. N6-methyl-adenosine (m6A) is the most prevalent mRNA modification, established by "writer" and "eraser" p...
Depth-specific fluctuations of gene expression and protein abundance modulate t...
Procaccini, Gabriele; Ruocco, Miriam; Marin-Guirao, Lazaro; Dattolo, Emanuela; Brunet, Christophe; D'Esposito, Daniela; Lauritano, ChiaraHere we present the results of a multiple organizational level analysis conceived to identify acclimative/adaptive strategies exhibited by the seagrass Posidonia oceanica to the daily fluctuations in the light environment, at contrasting depths. We assessed changes in photophysiological parameters, leaf respiration, pigments, and protein and mRNA expression levels. The results show that the diel oscillations of...
Linking gene expression to productivity to unravel long-and short-term response...
Olive, Irene; Silva, João; Lauritano, Chiara; Costa, Monya M.; Ruocco, Miriam; Procaccini, Gabriele; Santos, RuiOcean acidification is a major threat for marine life but seagrasses are expected to benefit from high CO2. In situ (long-term) and transplanted (short-term) plant incubations of the seagrass Cymodocea nodosa were performed near and away the influence of volcanic CO2 vents at Vulcano Island to test the hypothesis of beneficial effects of CO2 on plant productivity. We relate, for the first time, the expression o...
Genomewide transcriptional reprogramming in the seagrass Cymodocea nodosa under...
Ruocco, Miriam; Musacchia, Francesco; Olivé, Irene; Costa, Monya; Barrote, Isabel; Santos, Rui; Sanges, Remo; Procaccini, Gabriele; Silva, JoãoHere, we report the first use of massive-scale RNA-sequencing to explore seagrass response to CO2-driven ocean acidification (OA). Large-scale gene expression changes in the seagrass Cymodocea nodosa occurred at CO2 levels projected by the end of the century. C. nodosa transcriptome was obtained using Illumina RNA-Seq technology and de novo assembly, and differential gene expression was explored in plants expos...
