Seed-specific promoters (SSPs) can direct the expression of genes specifically in seeds to avoid undesirable effects associated with constitutive expression. However, few SSPs have been identified in peanut. Previous studies have shown that some allergen-encoding genes encode seed storage proteins or exhibit seed-specific/preferential expression. In this study, we characterized allergen-encoding genes from across the genomes of <em>Arachis</em> species to explore seed-specific genes. We found that at least 9 out of 16 identified peanut allergen-encoding genes were expressed specifically in the seeds or were preferentially expressed. A 1493-bp promoter fragment of allergen gene <em>Ara h 1</em> (we named it AHSSP6) was isolated from cultivated peanut genome. <em>cis</em>-element analysis showed that three RY repeat elements which usually exsisted in seed or embryo specific promoter sequence were also present in AHSSP6 sequence. Histochemical analysis showed AHSSP6 could drive the expression of a β-glucuronidase (<em>GUS</em>) reporter gene specifically in the seeds or cotyledon tissue of transgenic <em>Arabidopsis,</em> while not in other tissues. These findings indicated that these promoters of allergen genes were candidate SSPs, and AHSSP6 was a novel SSP which could be potentially utilized in peanut improvement.</p></div>","PeriodicalId":34095,"journal":{"name":"Oil Crop Science","volume":"7 1","pages":"Pages 14-21"},"PeriodicalIF":0.0,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2096242822000021/pdfft?md5=0e7d627fb163df8ca332ccee10ad0bd7&pid=1-s2.0-S2096242822000021-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46623463","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}

However, heterozygosity, low productivity and poor understanding of its genome are the major impediments to elite line development. Further, classical breeding and advanced technological investments remain limited owing to long juvenile phase and breeding cycles. Scientific technologies that lead to identification of elite genotypes and development of high yielding elite Jatropha lines and effective methods of detoxification of seeds needs immediate priority.

In the present investigation, we highlight the achievements made in Jatropha towards development of high yielding, virus resistant elite lines and hybrids with yield potential ranging from 3 to 5 tons per hectare in a year, which is a first ever report in the world. We also developed potential biotechnological tools such as genetic transformation, genome editing and next generation genomics tools including linkage maps and QTLs for accelerating breeding efforts through marker assisted selection.
