The principal SGs include stevioside (STV) and Rebaudioside-A (Reb-A), with the latter exhibiting superior sweetness and organoleptic properties. UDP glucosyltransferase-76G1 (UGT76G1) is responsible for converting STV to Reb-A, determining the intensity of sweetness. A better understanding of the structure/activity of SrUGT76G1 could provide insights into Reb-A production in stevia plants. To this end, a combination of enzymatic assays and sequencing analysis was performed using two stevia genotypes (Brazilian and Spanish) with contrasting Reb-A production capabilities (off/on). Relative expression of SrUGT76G1 gene showed remarkably higher expression (~ threefold) in Spanish samples compared to Brazilian ones. Foliar protein fractions (crude or partially purified extract) from Brazil plants were unable to convert STV into Reb-A under in vitro conditions, resulting in undetectable levels of Reb-A by HPLC. Molecular analyses revealed that the Brazilian SrUGT76G1 gene not only presents a premature stop codon, resulting in the absence of PSPG motif responsible for the binding of glycosyl groups, but also exhibits mutations affecting key amino acid residues in the acceptor-binding pocket. These alterations provide a plausible explanation for the Brazilian protein inability to catalyze the transformation of STV into Reb-A.<h3 data-test=\"abstract-sub-heading\">Graphical abstract</h3>\u0000","PeriodicalId":16835,"journal":{"name":"Journal of Plant Biochemistry and Biotechnology","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"2024-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140926868","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}

In peanuts, the expression of the Fatty Acid Desaturase 2 (FAD2) enzyme, which converts oleic acid to linoleic acid, is regulated by two homeologous genes called AhFAD2A and AhFAD2B. It has been observed that the Indian peanut cultivar GG20 does not possess natural mutations in the AhFAD2B gene. We successfully introduced a construct called CRISPR_GG20_AhFAD2B into the de-embryonated cotyledon of the GG20 plant. The purpose of this construct was to utilize the CRISPR-Cas9 gene editing technology to modify the AhFAD2B gene. Genotyping analysis of the plants that were potentially transformed with the construct confirmed that the target-specific editing had occurred in the AhFAD2B gene. Subsequently, the edited GG20 plants were phenotypically evaluated to assess the fatty acid composition in the peanut kernels. The results showed a notable increase in the O/L ratio, which rose from 3.1 in the control to 7.3 in the edited GG20 plants. This implies that the gene editing technique successfully enhanced the oleic acid to linoleic acid ratio in the peanuts, potentially improving the shelf life of the resulting peanut oil.","PeriodicalId":16835,"journal":{"name":"Journal of Plant Biochemistry and Biotechnology","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"2024-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140883656","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 consumption of food derived from plants contaminated with arsenate contributes significantly to human exposure to arsenic, posing potential health risks. However, the mechanisms governing plant responses to arsenate stress and the regulation of relevant transporter functions remain inadequately understood. Recently, Wang and co-workers, identified a calcium-dependent protein kinase, specifically CALCIUM-DEPENDENT PROTEIN KINASE 23 (CPK23), which shows interaction with the plasma membrane As(V)/Pi transporter PHOSPHATE TRANSPORTER 1;1 (PHT1;1) to channelize the Ca2+ signal in Arabidopsis roots under As(V) stress. The authors observed that cpk23 mutants showed increased sensitivity, whereas the overexpression of CPK23 resulted in enhanced tolerance under As(V) stress conferring role in As stress. Moreover, it has been demonstrated that CPK23 phosphorylates PHT1.1 at the Ser514 (S514) site is crucial for its function and proper localization under As(V) stress.

The seeds of pigeonpea contain approximately 20–22% digestible protein, which makes it a valuable source of nutrition.

Recently, high-protein germplasm lines have been discovered in the secondary gene pool, which presents an opportunity to breed for high-protein cultivars. To accelerate the breeding process, genomics-assisted breeding (GAB) can be utilized. In this context, this study identified the superior haplotypes for the genes that control SPC in pigeonpea. Whole-genome re-sequencing (WGRS) data from 344 pigeonpea genotypes were analyzed to identify the superior haplotypes for 57 SPC governing genes. A total of 231 haplotypes in 43 candidate genes were identified, and haplo-pheno analysis was performed to provide superior haplotypes for 10 genes.

In vitro studies have revealed Artemin's role as a molecular chaperone, effectively engaging with the hydrophobic surfaces of unfolded and/or partially folded proteins. In light of Artemin's established functional significance, its encoding gene has been successfully introduced into mammalian cells; however, no published research has elucidated its potential role within plant cells. In the current investigation, the artemin gene was successfully cloned into the pPZPY122 plant vector and subsequently introduced into Arabidopsis thaliana plants. The T3 homozygote transgenic plants (art) were then subjected to a series of environmental stresses, including heat, salt (NaCl) and drought (Mannitol). To assess the mutant's resilience to these stresses, their seed germination indices were evaluated. The art line demonstrated a higher degree of tolerance towards the abiotic stresses. A comparative analysis revealed that ascorbate peroxidase activity, catalase activity, and proline content exhibited significantly enhanced levels in some NaCl-treated art plants compared to their counterparts in Col-0. Regarding the expression of the genes in the SOS pathway, it was found that SOS1 is significantly upregulated under NaCl treatment in the art mutant. Conversely, under normal growth conditions, the morphology and growth of transgenics remained indistinguishable from those of wild-type plants.","PeriodicalId":16835,"journal":{"name":"Journal of Plant Biochemistry and Biotechnology","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"2024-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140147219","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}

Therefore, current global agricultural production needs to be increased to feed the unconstrained growing population. The changing climatic condition due to anthropogenic activities also makes the conditions more challenging to meet the required crop productivity in the future. Potato is third most consumed staple food. The current cultivation and demand of potato is particularly more in developing countries with high levels of poverty, hunger, and malnutrition because it is cheap source of nutrition and easily available. Potato is severely infected by a number of diseases, insect pests, and abiotic environmental conditions. Amidst the backdrop of climate change, the situation is deteriorating. Projections indicate that the average potato productivity in India's primary potato-growing states, responsible for approximately 90% of the nation's total potato output, is expected to decline by 2.0% in the 2050s and a more substantial 6.4% in the 2080s. Therefore to develop tolerance in plants to cope with changing environmental condition is need of hour to feed the overgrowing population. In this review, we discussed the application of CRISPR to enhance the crop productivity and develop biotic and abiotic stress-tolerant in potato to face the current changing climatic conditions is also discussed. The review also sheds light on the future prospects of CRISPR/Cas technology for potato breeding, including potential challenges and opportunities.","PeriodicalId":16835,"journal":{"name":"Journal of Plant Biochemistry and Biotechnology","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"2024-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140036684","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}
