The formation of peanut pod requires movement of the embryo from air to ground and then development in the soil, which is a complex biological process involving transport and accumulation of sugars. Sugar transport proteins (STP) mediate the transport of monosaccharides in various physiological processes, including fertilization, ovary formation, and seed development. In this study, a total of 36 <em>AhSTP</em> genes (<em>AhSTP1–36</em>) containing the conserved sugar_tr motif were identified in the <em>A. hypogaea</em> genome. Phylogenetic analysis revealed that <em>AhSTP</em> genes were classified into four clades, and the arrangement of motifs in AhSTP proteins was similar within clades. Synteny analysis revealed that segmental duplication events have played an important role in the expansion of <em>STP</em> genes in peanut, and chromosome rearrangements might have facilitated the exchange of <em>STP</em> genes between the A and B sub-genomes. Transcriptome analyses revealed that the expression patterns of <em>AhSTP</em> genes varied among tissues. Hormone and abiotic stress treatments could up-regulate or down-regulate the expression of <em>AhSTP</em> genes, and low temperature had a major effect on the expression of most <em>AhSTP</em> genes. Four <em>AhSTP</em> genes (<em>AhSTP3</em>, <em>AhSTP9</em>, <em>AhSTP19</em>, and <em>AhSTP28</em>) were specifically expressed in the pod, indicating that these genes might be involved in pod formation and development in peanut. The unique expression of these four genes during pod construction and development was confirmed in two different type cultivars using quantitative real-time PCR analysis. Our findings provide new insights into the <em>STP</em> gene family in peanut and will aid future functional studies of <em>AhSTP</em> genes.</p></div>","PeriodicalId":34095,"journal":{"name":"Oil Crop Science","volume":"7 4","pages":"Pages 189-199"},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2096242822000380/pdfft?md5=de351ada4b5d0492f14aea635393df6d&pid=1-s2.0-S2096242822000380-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41880618","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The technical features of global patents are mainly concentrated in pharmaceutical preparations, cosmetics, food and health care, various beverages, animal feed, safflower cultivation and harvesting equipment, and safflower seed oil. During the rapid development of patent applications, safflower was further developed in cosmetics, edible oil, and harvesting equipment. In addition, patent applications in rheumatism and bone diseases have increased, with the potential for development. China is the leading region for researching and developing medicinal safflower patents, especially Shandong and Henan provinces. Foreign patents are more focused on the value development of safflower seed oil in food and chemicals. Compared to the major countries and organizations that apply for safflower patents on a global scale, the quality of Chinese safflower patents is medium, and more awareness of patent protection is required.

Although attention has been drawn to some plant FA desaturase genes, their global landscape in oil crops is still lacking. Here, we performed systematic characterization and phylogenomic synteny network analyses of the FA desaturase gene family in polyploid oil crop <em>B. napus</em> and other 54 species covering major streptophyte lineages. A total of 1653 FA desaturase genes were identified from these plant genomes. Based on the broad-scale family phylogeny and functional domains, we proposed a unified eight-group classification system for angiosperm FA desaturases, and found that the origin of genes responsible for FA desaturation evolved early and some genes were absent in different species. Phylogenomic analyses revealed deeply conserved syntenic relationships within each of the eight FA desaturase groups. <em>B. napus</em> contains up to 93 FA desaturase genes from the eight groups. Recurrent duplication events in Brassicaceae contributed to the expansion of FA desaturase genes in <em>B. napus</em>, leading to further functional diversification. These FA desaturase genes exhibited spatio-temporal specific expression patterns in different tissues of <em>B. napus</em>, and a set of FA desaturase genes seem to be orchestrated by key transcriptional factors during seed development, such as zf-HD, B3, GATA3, PEI1, NFYA7, YAB1 and YAB2. Altogether, our data have inferred the evolutionary trajectory of this important gene family across distinct plant lineages, providing theoretical basis for future manipulation of FA desaturase genes to improve the seed oil quality of <em>B. napus</em>.</p></div>","PeriodicalId":34095,"journal":{"name":"Oil Crop Science","volume":"7 4","pages":"Pages 200-208"},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2096242822000410/pdfft?md5=dc5f06a461bf520dfa37bce5ab493fb7&pid=1-s2.0-S2096242822000410-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47469742","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
