As proposed by the Disposable Soma Theory, this lifespan variation among plants likely reflects differential investment of limited energy and nutrient resources, with perennials investing more energy and nutrients into biomolecular maintenance compared to annuals in order to ensure persistence over multiple seasons. Such differential investment may be particularly important during periods of exogenous stress, which are known to accelerate biomolecular damage. The present study evaluated this hypothesis using annual and perennial flax (<em>Linum</em> L.) subjected to two exogenous stressors—increased oxidative stress (i.e., foliar H₂O₂ spraying) and complete prolonged darkness. As chlorophyll has been shown to exhibit degradation in response to changes in environmental conditions, we utilized changes in chlorophyll levels during and after periods of exogenous stress to evaluate our hypotheses. We predicted that i) perennials would exhibit a slower rate of chlorophyll degradation during exposure to exogenous stressors compared to annuals, and ii) perennials would exhibit a faster rate of chlorophyll resynthesis following such exposure compared to annuals. Chlorophyll levels before, during, and after exposure to both exogenous stressors were measured in two separate trails, once using image colour analysis and once using spectrophotometry. While chlorophyll degradation rates in response to oxidative stress did not differ between annuals and perennials, contrary to our predictions, chlorophyll resynthesis rates following such exposure were significantly higher in perennials, as predicted. When plants were subjected to complete prolonged darkness, chlorophyll degradation rates were significantly lower in perennials than annuals, as predicted; however, when plants were subsequently reintroduced to natural photoperiod, chlorophyll resynthesis rates did not consistently differ between annuals and perennials, though they tended to be higher in the latter, as predicted. Overall, our study illuminates that evolutionary transitions between life history strategies in plants have been accompanied by physiological modifications to chlorophyll dynamics that permit perennial species to better maintain chlorophyll levels—and thus photosynthetic energy acquisition—in the face of exogenous stressors, which likely underlies their capacity to survive for multiple growing seasons. Future studies should explore whether other key biomolecules (e.g., proteins, DNA) are also better maintained in perennial plants, especially in the face of exogenous stress.</p></div>","PeriodicalId":34095,"journal":{"name":"Oil Crop Science","volume":"9 2","pages":"Pages 121-130"},"PeriodicalIF":0.0,"publicationDate":"2024-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2096242824000277/pdfft?md5=b969924d8f3ac81d0f1b75e4a11fd728&pid=1-s2.0-S2096242824000277-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141040216","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

SHI RELATED SEQUENCE (SRS) proteins are the transcription factors (TFs) specific to plants that contain RING-like zinc figure domain and are associated with the regulation of several physiological and biochemical processes. They also play vital roles in plant growth and development such as root formation, leaf development, floral development, hormone biosynthesis, signal transduction, and biotic and abiotic stress responses. Nevertheless, the <em>SRS</em> gene family was not reported in sesame yet. In this study, identification, molecular characterization, phylogenetic relationship, <em>cis</em>-acting regulatory elements, protein-protein interaction, syntenic relationship, duplication events and expression pattern of <em>SRS</em> genes were analyzed in <em>S. indicum</em>. We identified total six <em>SiSRS</em> genes on seven different linkage groups in the <em>S. indicum</em> genome by comparing with the other species, including the model plant <em>Arabidopsis thaliana</em>. The <em>SiSRS</em> genes showed variation in their structure like 2–5 exons and 1–4 introns. Like other species, <em>SiSRS</em> proteins also contained ‘RING-like zinc figure’ and ‘LRP1’ domains. Then, the <em>SiSRS</em> genes were clustered into subclasses via phylogenetic analysis with proteins of <em>S. indicum, A. thaliana,</em> and some other plant species. The <em>cis</em>-acting regulatory elements analysis revealed that the promoter region of <em>SiSRS4</em> (SIN_1011561) showed the highest 13 and 16 elements for light- and phytohormone-responses whereas, <em>SiSRS1</em> (SIN_1015187) showed the highest 15 elements for stress-response. The ABREs, or ABA-responsive elements, were found in a maximum of 8 copies in the <em>SiSRS3</em> (SIN 1009100). Moreover, the available RNA-seq based expression of <em>SiSRS</em> genes revealed variation in expression patterns between stress-treated and non-treated samples, especially in drought and salinity conditions in<em>. S. indicum</em>. Two <em>SiSRS</em> genes like <em>SiSRS1</em> (SIN_1015187) and <em>SiSRS5</em> (SIN_1021065), also exhibited variable expression patterns between control vs PEG-treated sesame root samples and three <em>SiSRS</em> genes, including <em>SiSRS1</em> (SIN_1015187), <em>SiSRS2</em> (SIN_1003328) and <em>SiSRS5</em> (SIN_1021065) were responsive to salinity treatments.

In this study, Near Infrared Spectroscopy (NIRS) was applied to rapidly assess germplasm variability from whole seed of 699 samples, field-collected and assembled in four genetic and environment-based sets: one set of 300 varieties of a core-collection and three sets of 133 genotypes of an interspecific population, evaluated in three environments in a large spatial scale of two countries, Mbalmayo and Bafia in Cameroon and Nioro in Senegal, under rainfed conditions. NIR elemental spectra were gathered on six subsets of seeds of each sample, after three rotation scans, with a spectral resolution of 16 cm^-1 over the spectral range of 867 nm to 2530 ​nm. Spectra were then processed by principal component analysis (PCA) coupled with Partial least squares-discriminant analysis (PLS-DA). As results, a huge variability was found between varieties and genotypes for all NIR wavelength within and between environments. The magnitude of genetic variation was particularly observed at 11 relevant wavelengths such as 1723 ​nm, usually related to oil content and fatty acid composition. PCA yielded the most chemical attributes in three significant PCs (i.e., eigenvalues &gt;10), which together captured 93% of the total variation, revealing genetic and environment structure of varieties and genotypes into four clusters, corresponding to the four samples sets. The pattern of genetic variability of the interspecific population covers, remarkably half of spectrum of the core-collection, turning out to be the largest. Interestingly, a PLS-DA model was developed and a strong accuracy of 99.6% was achieved for the four sets, aiming to classify each seed sample according to environment origin. The confusion matrix achieved for the two sets of Bafia and Nioro showed 100% of instances classified correctly with 100% at both sensitivity and specificity, confirming that their seed quality was different from each other and all other samples. Overall, NIRS chemometrics is useful to assess and distinguish seeds from different environments and highlights the value of the interspecific population and core-collection, as a source of nutritional diversity, to support the breeding efforts.</p></div>","PeriodicalId":34095,"journal":{"name":"Oil Crop Science","volume":"9 2","pages":"Pages 132-141"},"PeriodicalIF":0.0,"publicationDate":"2024-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2096242824000241/pdfft?md5=c346609e816dacff868dbdf230d628b2&pid=1-s2.0-S2096242824000241-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141046499","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
