Hence, the first step in their characterization is the estimation of transgene copy numbers integrated in the plant genome. Quantitative real-time PCR (qRT-PCR) was used to determine the copy numbers of human interferon-γ (<i>hIFN</i>-γ) and hygromycin phosphortransferase II (<i>hpt</i>II) transgenes in the genome of the T<sub>0</sub> generation of 18 transgenic tobacco lines using the <i>axi</i>1 gene as an endogenous control. With optimized PCR conditions, we attained highly exact estimates of one, two, three, and/or four transgene copies in the T<sub>0</sub> transformants. Moreover, estimation of copy numbers of the <i>hIFN</i>-γ transgene and the <i>hpt</i>II selective marker gene indicated that rearrangements of the T-DNA has regularly happened in transgenic tobacco. Transgene copy number was also estimated using Southern blot analysis of gDNA derived from transformants. The transcript level and expression amount of recombinant hIFN-γ protein were evaluated in various events using RT-PCR and enzyme-linked immunosorbent assay (ELISA) techniques.

The upregulation of <i>ETC1</i> and <i>ETC3</i> in response to phosphorus deficiency was restricted to the roots, with no such response observed in leaves. Furthermore, examination of ETC3:GFP protein localization revealed that ETC3 expression was induced in the internal root tissues under phosphorus deficiency, without migrating to epidermal cells as observed for ETC1.

Despite their agricultural and pharmaceutical value, breeding programs for <i>Allium</i> species are lagging behind those of other major crop plants. MicroRNAs (miRNAs) are a group of small non-coding RNAs that regulate post-transcriptional gene expression. In order to identify distinct miRNAs and their target proteins involved in Allicin biosynthesis pathways under heat-stress conditions, available <i>Allium</i> species Expressed Sequence Tags (ESTs) and miRNA databases were extensively searched and bioinformatically analyzed. Three distinct miRNA candidates targeting seven genes in garlic were identified. The real-time RT-PCR analysis results revealed that miR5021 and miR565 regulate the Alliinase and Heat shock protein 70 (HSP70) genes under cold stress (4°C), while miR5184 regulates the same genes at elevated temperatures (37 and 45°C). Based on the High-Performance Liquid Chromatography (HPLC) results, the expression of the Alliinase gene was found to be higher in both stem and leaf tissues compared to the expression of miR5021 under cold stress conditions. This indicates the potential involvement of miR5021 in the biosynthetic pathway of Allicin production. Furthermore, the results of the elevated heat-stress treatment showed that the expression of the HSP70 gene under thermal stress conditions at 37°C in both stem and leaf tissue was significantly increased compared to the expression of miR5658 and miR5184 at 45°C. However the expression of the HSP70 gene in the stem tissue was significantly decreased compared to the expression of miR5658 and miR5184 genes. This experimental study aims to identify miRNAs associated with the allicin production pathway in two tissues of garlic: leaves and cloves. Among the main findings of this research, we can mention the identification of 3 miRNAs that are likely to play a role in the allicin synthesis pathway.

Seven chromosomal regions showed QTLs for more than two traits. QTLs were associated with several high priority candidate genes for grain Fe, Zn and yield. One elite BIL [IET 24775 RP4920-Bio51B] was tested in AICRIP bio fortification trials for 4 years [2014–2017], and three BILs [IET 28715 RP4920-Bio61-1B], [IET28706 RP4920-Bio83B] and [IET28695 RP4920-Bio88B] are evaluated for 2 years of trials. The significant BILs and QTLs are useful in rice bio fortification and for gene discovery.</p>","PeriodicalId":16835,"journal":{"name":"Journal of Plant Biochemistry and Biotechnology","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"2024-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139077155","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}
