Fifteen ISSR primers were tested using genomic DNA of selected coffee varieties.

The size range of locus amplified by all the fifteen primers was ranging from 100 to 1200 bp depending upon on the ISSR primers. Only three out of fifteen primers, namely ISSR4, ISSR6 and ISSR8, were screened based on the number of amplified locus and size range from low to high. The selective ISSR primers distinguished all the six varieties of coffee with unique markers. ISSR 4 amplified two unique markers with a locus size 1300 bp and 950 bp for Sln.5B and 180 bp and 150 bp for Sln.13.

Given the substantial expression of programmed death ligand 1 (PD-L1) in the human multiple myeloma cell line RPMI8226, we propose PD-L1 as a promising target for multiple myeloma therapy. Here, we successfully engineered an anti-PD-L1 monoclonal antibody (mAb) within a plant-based system. Building upon our previous findings, we germinated seeds derived from transgenic plants under in vitro conditions. Afterward, we screened the resulting seedlings for expression of the anti-PD-L1 mAb using polymerase chain reaction (PCR) and western blot analyses. Anti-PD-L1 mAbs were successfully purified from plant leaves and characterized through SDS-PAGE analysis. Our findings, which were confirmed via indirect enzyme-linked immunosorbent assay (ELISA), validate the binding affinity of the anti-PD-L1 mAb to recombinant PD-L1 protein. Furthermore, we investigated the interaction between the plant-derived anti-PD-L1 mAb and Fc gamma receptor I (FcγRI) as well as Fc gamma receptor IIIa (FcγRIIIa) molecules, confirming robust affinity. Additionally, the antibody’s binding affinity to the human multiple myeloma cancer cell line RPMI8226 was confirmed via cell ELISA. Our findings demonstrated that, unlike existing therapeutics, the plant-derived anti-PD-L1 antibody not only effectively binds to human recombinant PD-L1 protein but also to FcγRI and FcγRIIIa.

The change in global climatic patterns affects photosynthesis that subsequently reduces plant yield and poses threat to food security.

The fixation rate of CO<sub>2</sub> to O<sub>2</sub> depends upon the relative concentration of CO<sub>2</sub> inside chloroplast. Higher level of CO<sub>2</sub> results in improved photosynthesis, however, its concentration depends upon environmental conditions. Under adverse climate conditions, the CO<sub>2</sub> level drops down that leads to increased oxygenation which impedes the photosynthesis and reduces plant productivity.

PnCHS1 had a 32.8–53.7% similarity to CHS from other species, however it still had highly conserved motifs of CHS such as Catalytic site (Asn366, His333) and Co-A binding site (Ser146).

Heterologous expression of <i>PnCHS1</i> boosted tolerance to oxidative stress while decreasing the sensitivity to ABA. Under H<sub>2</sub>O<sub>2</sub> or ABA stress, the expression pattern of <i>PnCHS1</i>, ROS scavenging enzyme gene (FeSOD1, FeSOD2, Cu-Zn-SOD2, and Cu-Zn-SOD3) and three genes of ABA signal pathway (RAB18, RD29B, and NCED3) were considerably up-regulated by real-time quantitative analysis. It indicates that <i>PnCHS1</i> could enhance plant tolerance to NaCl and oxidative stresses, and may play a role in the adaptation of Antarctic moss to extreme environments.</p>","PeriodicalId":20216,"journal":{"name":"Plant Biotechnology Reports","volume":"21 9","pages":""},"PeriodicalIF":2.4,"publicationDate":"2023-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138507418","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}
