The primary component of secondary cell wall, lignin, imparts strength and rigidity and enables plants to endure negative pressure created during transpiration. Members of the <em>MYB</em> transcription family, <em>AtMYB42</em> and <em>AtMYB85,</em> play critical roles as regulators of lignin biosynthesis. Inspite of their functional significance, evolutionary history of homologs of <em>AtMYB42</em> and <em>AtMYB85</em> across land plants remains to be investigated. Our analysis revealed that homologs of <em>AtMYB42</em> and <em>AtMYB85</em> as two distinct genes are not present in any plant lineage outside Brassicaceae and only the ancestral form exists as <em>AtMYB42</em>/<em>AtMYB85</em>. Analysis of homologs of <em>AtMYB42</em> and <em>AtMYB85</em> across green plants combined with comparative genomics, selection pressure, and character-state reconstruction reveals that <em>AtMYB42</em> and <em>AtMYB85</em> are paralogous, and arose via segmental duplication, which may coincide with the α-event of WGD that occurred after the split of Brassicaceae-Caricaceae from the last common ancestor<em>.</em> Within Brassicaceae, homeologs and paralogs that arose as a result of polyploidization, and species- and lineage-specific changes could be observed. For instance, homologs of <em>AtMYB42</em> were found to be deleted from the entire <em>Brassica</em> lineage. Analysis of homeologous segments in neopolyploids (<em>B. napus, B. juncea, Camelina sativa</em>), and meso-polyploid (<em>B. rapa</em>) revealed differential degrees of gene loss and retention. In Brassicaceae, homologs of <em>AtMYB42</em> were found to be under purifying selection and of <em>AtMYB85</em> under positive selection. High sequence identity in the coding region between homologs of <em>AtMYB42</em> and <em>AtMYB85</em> is indicative of redundant roles, and the loss of homologs of <em>AtMYB42</em> in <em>Brassica</em> may be compensated by presence of <em>AtMYB85</em> homologs and homeologs. The study thus forms the basis to investigate questions on regulatory diversification owing to variation in cis-elements between the paralogs and among homeologs, and, impact of differential selection pressure vis-a-vis redundant function.</p></div>","PeriodicalId":38041,"journal":{"name":"Plant Gene","volume":"35 ","pages":"Article 100424"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49209882","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While several miRNAs have been implicated in the modulation of multiple abiotic and biotic stresses in rice, there role in response to fluoride stress is yet to be explored. In the present study, fourteen conserved rice miRNAs with proven role in multiple stress response were analysed to identify differentially expressed miRNAs in response to fluoride toxicity in two popular rice varieties- Gobindobhog (GB; F-tolerant) and IR64 (F-sensitive). Stem-Loop RT-PCR revealed that miR156, miR166, and miR171 were significantly induced in GB seedlings post treatment with fluoride. Likewise, miR160, miR319, miR396, and miR444 were prominently induced in the fluoride-sensitive IR64. Additionally, miR393 was significantly induced post-treatment with fluoride stress in both the genotypes exhibiting a basal response to fluoride toxicity. Further, we computationally predicted the miRNA targets many of which encoded transcription factors associated with stress response mechanism. The miRNA targets were experimentally validated using ligation mediated 5′ rapid amplification of cDNA ends analysis. Quantitative RT-PCR analysis of nine selected miRNA target genes (Os11g30370, Os06g47150, Os06g03670, Os04g48290, Os02g44360, Os08g34380, Os05g05800, Os04g57050, Os04g51350) revealed simultaneous reciprocal changes in the expression patterns of the miRNAs and the corresponding target genes suggesting their involvement in the modulation of fluoride stress response in rice. Analysis of proximal promoter sequences of the F-responsive miRNAs revealed that these miRNAs possess stress-responsive, elicitor and hormonal related motifs. Overall, our results suggest that multiple conserved miRNAs are involved in fluoride toxicity and a miRNA-mediated regulation of signal response is critical for rice response to fluoride stress.</p></div>","PeriodicalId":38041,"journal":{"name":"Plant Gene","volume":"35 ","pages":"Article 100426"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45752757","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, this study aims to evaluate the diversity and genetic structure in <em>M. brauna</em> matrixes established in multiclonal minigardens through inter simple sequence repeat (ISSR) markers. Plant material of 59 individuals arranged in the multiclonal minigarden was collected for the analyses. Eleven ISSR primers were selected, which generated 183 fragments, among which 117 were polymorphic (63,93%). The efficiency of the markers was confirmed through the polymorphism information content (PIC) which resulted in an average value of 0.36, characterizing them as moderately informative. High genetic diversity was found based on the values of the number of observed alleles (A_O = 2.00) and effective alleles (A_E = 1.63), Nei's diversity index (<em>H*</em> = 0.36), Shannon index (<em>I*</em> = 0.54), and the formation of distinct groups by cluster analysis. Despite the alleles being well distributed among individuals, revealing high genetic diversity, Bayesian inference revealed only one genetic group (K = 1). The ISSR markers proved to be efficient in the characterization of the genetic diversity in <em>M. brauna</em> individuals, and the population of the multiclonal minigarden can be used as a source of propagules for seedling production.

Therefore, they have a significant role in the regulation of sugar metabolism. This study focused on the function of the SPS homolog -<em>pvSPS4</em>- in the roots of legume crop common bean under salinity stress. We previously showed that <em>pvSPS4</em> expression is root-specific and is upregulated under salt stress in a salt-tolerant common bean genotype. This upregulation was accompanied by an accumulation of sugars in the roots. In the current study, using the same genotype, we generated composite common bean plants with wild-type shoot and <em>pvSPS4</em> knock-down roots. Composite plants exhibited a more sensitive phenotype under salt stress compared to control and mock plants. <em>pvSPS4</em> knock-down disturbed the root glucose/sucrose ratio and balance of Ca⁺², Mg⁺², and K⁺ in both root and leaves which resulted in a reduction in photosynthetic pigments together with osmoregulation and antioxidant capability.

Here we evaluate the potential of Extreme-Phenotype GWAS (XP-GWAS) to identify candidate genes underlying a quantitative trait in <em>Eucalyptus,</em> using the timing of leaf heteroblasty as a case study. XP-GWAS involves genotyping pools of individuals grouped by extreme and opposed phenotypes from a population or a diversity panel and studying their allele frequency. Using a previous phenotyped trial of <em>E. globulus</em>, we sequenced pools of 50 individuals that notably differ in the onset of adult foliage. Since the genetic basis of heteroblasty is well understood, we first searched for previously identified genes. Secondly, we searched for new candidate genes and also evaluated the copy number variation (CNVs) that may be involved in this process. We found marginally significant SNPs associated with previously described microRNAs, and interesting new non-coding RNAs. Disease resistance genes were also uncovered, probably as a consequence of indirectly selecting resistant trees, although a possible interaction between resistance and heteroblasty cannot be disregarded either.
