Cloning, structural characterization, and phylogenetic analysis of flower MADS-box genes from crocus (Crocus sativus L.).
Crocus (Crocus sativus L.) is a crop species cultivated for its flowers and, more specifically, for its red stigmas. The flower of crocus is bisexual and sterile, since crocus is a triploid species. Its perianth consists of six petaloid tepals: three tepals in whorl 1 (outer tepals) and three tepals in whorl 2 (inner tepals). The androecium consists of three distinct stamens and the gynoecium c...
متن کاملStructural characterization of highly glucosylated crocins and regulation of their biosynthesis during flower development in Crocus
Crocin biosynthesis in Crocus has been proposed to proceed through a zeaxanthin cleavage pathway catalyzed by carotenoid cleavage dioxygenase 2 (CCD2), and followed by glucosylation reactions catalyzed by CsGT2 (UGT74AD1). In Crocus ancyrensis flowers, crocins with eight (crocin-1), seven (crocin-2), and six glucose (crocin-3) moieties accumulated both in stigma and tepals. We have characterize...
متن کاملCharacterization of MADS box genes from hot pepper.
The cDNA clone, CanMADS1, was isolated from young flower buds of the hot pepper (Capsicum annuum L.) by screening a cDNA library using the OsMADS1 rice MADS-box gene as a probe. We used a yeast two-hybrid screening method to investigate interaction partners of the protein product of CanMADS1. A MADS-box gene, CanMADS6, was isolated from young flower buds using the region containing the K domain...
متن کاملFunctional characterization of MADS box genes involved in the determination of oil palm flower structure.
In order to study the molecular regulation of flower development in the monoecious species oil palm (Elaeis guineensis), cDNAs of 12 MADS box genes from this plant belonging to seven distinct subfamilies were previously isolated and characterized. Here studies carried out on five of these genes, each likely to be involved in floral morphogenesis: EgSQUA1 (SQUAMOSA subfamily); EgAGL2-1 (AGL2 sub...
متن کاملبررسی بیان ژن‌های عوامل رونویسی MADS-box موثر در تشکیل گل در زعفران (Crocus sativus L.)
بسیاری از ژن‌های کنترل کننده گلدهی در گیاهان شناسایی شده‌اند که بیشتر آنها متعلق به خانواده بزرگ عوامل رونویسی MADS-box هستند. گیاه زعفران (Crocus sativus) یک گیاه تریپلوئید نرعقیم و ارزشمند است که به منظور استفاده از گل و بویژه کلاله آن کشت می‌شود. درک چگونگی تشکیل گل در گیاه زعفران به افزایش عملکرد و کاهش هزینه‌های تولید آن کمک زیادی می‌کند. در این تحقیق بیان ژن‌های دو گروه Ag1 و Sep3 از خانو...
