It’s a plant species growing in calcareous soil of limestone, which means they can grow well in high calcium environment. Compared with <i>C. limonia</i>, <i>Camellia nitidissima</i> is a plant growing in acidic soil, which grows slowly or even dies in high calcium environment. However, there are few studies on <i>C. limonia</i> in karst soil environment and its adaptation mechanism is no clear. In this study, we found that under high calcium treatment, the chlorophyll content and leaf areas of <i>C. limonia</i> increased, while those of <i>C. nitidissima</i> decreased. The photosynthetic efficiency of <i>C. limonia</i> was more stable and higher than <i>C. nitidissima</i>. Compared with <i>C. nitidissima</i>, the conductance was larger and the degree of leaf shrinkage was smaller in <i>C. limonia</i>. The metabolomics analysis of both leaves showed that the kaempferol-3-o-rutinoside, tyrosol, 6-o-methyldeacetylisoipecoside and (r)-mandelic acid are the main differently metabolic compounds. The results of metagenomics in karst soil showed that the secretion (propylene oxide) of <i>Acaryochloris marina</i> in rhizosphere is closely related to the adaptation of <i>C. nitidissima</i> in high-calcium regions. Through metabolomics and metageomics integrative analysis, flavone and flavonol biosynthesis were suggested to be the main regulation pathway, which were regulated by metabolites apigenin, kaempferol, astragalin, isoquercitrin and genes <i>TT7</i>, <i>UGT78D1</i>, <i>UGT78D2</i>. This metabolic pathway involved the synthesis of flavonoids. Flavonoids have the characteristics of drought resistance and salt resistance, which play an important role in the adaptation of <i>C. limonia</i> in karst high calcium environment. This omics study identified key regulation metabolites and genes for <i>Camellia</i> and provided important basis for the adaptive mechanism of plants to adapt to the high-calcium environment and the protection of <i>Camellia</i> species.</p>","PeriodicalId":54356,"journal":{"name":"Tropical Plant Biology","volume":"357 3","pages":""},"PeriodicalIF":2.0,"publicationDate":"2022-01-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138508400","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we report for the first time, transcriptome-wide characterization of miRNA profile from the leaves of C. asiatica using high-throughput Illumina sequencing. We identified 227 conserved and 109 putative novel miRNAs. Computational screening revealed potential mRNA targets for both the conserved and novel miRNAs encoding diverse transcription factors and enzymes involved in plant development, disease resistance, metabolic and signaling pathways. Gene ontology annotation and KEGG analysis revealed the miRNA targets to be involved in a wide range of metabolomic and regulatory pathways. The differential expression of the miRNA encoding genes in diverse tissues was determined by real-time PCR analysis. We also found that gene expression levels of miR156, 159 and 1171 was reduced in salicylic acid treated axenic shoot cultures of C. asiatica compared to its control. Furthermore, RLM-RACE experiments mapped miRNA-mediated cleavage at two of the mRNA targets. The present study represents the large-scale identification of microRNAs from C. asiatica and contributes to the base for the up-coming studies on miRNA-mediated gene regulation of plant secondary metabolite pathways in particular.","PeriodicalId":54356,"journal":{"name":"Tropical Plant Biology","volume":"1 1","pages":""},"PeriodicalIF":2.0,"publicationDate":"2021-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43384686","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The availability of reference genomic sequences for both diploid cultivated jute species enabled us to identify a total of 154,715 and 160,173 SSRs from the <i>C. capsularis</i> and <i>C. olitorius</i> genomes, respectively. 6,337 and 7,012 total SSRs with a density of 187.6 and 185.01 SSR/Mb were also mined in coding sequences (CDS). 12bp was the most common repeat length in both genomic and CDS. Di- and tetra-nucleotide motifs were prevailed in the genomic sequences, while trinucleotides in the CDS. SSR frequency declined with increasing repeat units in both species. ATT and AT motifs were the most common in the genome. AG and CTT were prevalent in the CDS of both species while GC and CGC motifs were infrequent. Further, we used the flanking sequences of identified SSRs (from both species) to design a total of 1,117 SSR primer pairs. Genetic diversity analysis based on 110 sampled SSRs in 24 genotypes displayed high polymorphism.
