چکیده | ||
Camelina (Camelina sativa), an oilseed plant in the Brassicaceae family, is recognized as a significant crop both biologically and industrially, with recent attention shifting towards its potential as a biofuel source. The close genetic resemblance between Arabidopsis thaliana and C. sativa has sparked interest among researchers in manipulating oleic acid levels through microRNAs and the gene sequences FAE1-A and FAD2-A. A recent bioinformatics study focused on these genes in camelina revealed that the FAE1-A protein is hydrophobic, while FAD2-A is hydrophilic. Structural analysis indicated GMQE values of 0.88% for FAE1-A and 0.93% for FAD2-A. The FAE1-A protein’s secondary structure comprises 49% helix, 11% beta-sheet, 41% coil, and 9% membrane content with a confidence level of 79.2%. Similarly, the secondary structure of the FAD2-A consists of 43% helix, 12% beta-sheet, 45% coil, and 30% membrane content with a confidence level of 79.8%. Codon preference patterns were explored using the Sequence Manipulation Suite database to understand the relationship between codons and gene performance. Furthermore, analysis of FAE1-A and FAD2-A gene expression showed peak expression levels in developing seeds approximately 20 days after pollination. Further investigation into these structures promises to enhance our understanding of fat biosynthesis, thereby improving oil quality in C. sativa. | ||

چکیده [English] | ||
گیاه کاملینا (Camelina sativa)، یک گیاه دانة روغنی از خانواده Brassicaceae، بهعنوان یک محصول مهم بیولوژیک و صنعتی شناخته میشود که بهتازگی با عنوان یک منبع سوخت زیستی در نظر گرفته شده است. به دلیل شباهت بسیار زیاد در توالیهای ژنی بین Arabidopsis thaliana و C. sativa، مهندسی اسید اولئیک از طریق microRNA ها و توالیهای ژن FAE1-A و FAD2-A، توجه گستردة محققان را به خود جلب کرده است. در مقاله حاضر، یک مطالعه بیوانفورماتیک بر روی ژنهای FAE1-A و FAD2-A در کاملینا انجام شد. نتایج نشان داد؛ پروتئین FAE1-A آبگریز است، در حالی که FAD2-A یک پروتئین آبدوست است. ارزیابی ساختارهای سه بعدی پروتئینها تایید کرد که مقادیر GMQE برای ژنهای FAE1-A و FAD2-A به ترتیب 88/0 و 93/0 درصد بود. ساختار ثانویه پروتئین FAE1-A شامل %49 هلیکس، %11 صفحه بتا، %41 کویل و %9 محتوای غشا، با سطح اطمینان 2/79 درصد بود. همچنین بررسی ساختار ثانویه پروتئین FAD2-A نشان داد که پروتئین دارای 43 درصد هلیکس، 12 درصد صفحه بتا، 45 درصد کویل و 30 درصد محتوای غشایی با سطح اطمینان 8/79 درصد است. ترجیح کدون نیز با استفاده از پایگاه داده Suite Manipulation Sequence مورد بررسی قرار گرفت که رابطة بین کدونها و عملکرد این ژنها را نشان میدهد. علاوه بر این، تجزیه و تحلیل بیان ژن FAE1-A و FAD2-A نشان داد؛ بیشترین میزان بیان در بذرهای در حال رشد، حداکثر 20 روز پس از گردهافشانی بود. در نهایت، بررسی دقیق این ساختارها، منجر به آگاهی بیشتر در مورد بیوسنتز چربیها، بهبود کیفیت روغن در C. sativa میشود. | ||
