چکیده

In the current study, a comprehensive analysis was performed on Arabidopsis WRKY transcription factor (TF) family members that their differential expression (DE) was reported under various stresses in GEO profile database. First, WRKY members with DE were extracted from GEO profile and information of the data set, sequence and their gene structure were obtained. Then, the concept of the intersection of sets was used to select some of WRKY TFs for downstream analysis. DE of candidate members was compared by t-test. The protein– protein interaction network were predicted by STRING web server. A total of ۱۶ WRKY genes were identified in the ۱۱ dataset of GEO profile. Analysis of the gene structure showed that ۵۶% of the studied WRKY genes have ۳ exons and all ۱۶ members are distributed across all five chromosomes of Arabidopsis. Also, the results showed that WRKY۴۰, WRKY۴۶, WRKY۱۸, and WRKY۳۳ were most frequently responsive to various stresses. The protein-protein interaction network showed that WRKY۴۰, WRKY۴۶, WRKY۱۸, and WRKY۷۰ have high interactions with four genes: MPK۴, ACS۶, MKS۱, and STZ. Therefore, WRKY۴۰, WRKY۴۶, WRKY۱۸, and WRKY۳۳ can be considered the most important WRKY TFs of Arabidopsis at response to various stresses and may find applications in genetic and metabolic engineering projects.

اطلاعات بیشتر در مورد COI

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.

کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
