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...

The fruit canning industry processes large quantities of the clingstone varieties of peach (Prunus persica L. Batch). The occurrence of split-pit formation--the opening of the pit and sometimes splitting of the fruit--causes deterioration of canned fruit quality. The frequency of split-pit formation is influenced by genetic and environmental factors. To increase understanding of the molecular m...

Chrysanthemummorifolium is one of the four major cut flowers in world, with high ornamental and economic value. Flowering time an important characteristic chrysanthemum that affects its value market. In Arabidopsis, FRUITFULL (FUL) gene plays a key role inducing flowering. Here, we isolated FUL clade MADS-box gene, CmFL3, from inflorescence buds. CmFL3 localized cellular membrane nucleus, showe...

The outside of the Arabidopsis thaliana fruit consists of three principal tissues: the valves or seedpod walls, the replum or central ridge between the valves, and the valve margins where the valves separate from the replum to disperse the seeds. Previous studies have shown that valve margin formation is specified by the SHATTERPROOF MADS-box transcription factors and that valve development is ...

In diploid wheat (Triticum monococcum), and likely in other Triticeae species, the VRN1 gene is essential for the initiation of the reproductive phase, and therefore, a detailed characterization of its regulatory regions is required to understand this process. A CArG-box (MADS-box-binding site) identified in the VRN1 promoter upstream from the transcription initiation site has been proposed as ...

Through multifaceted genome-scale research involving phylogenomics, targeted gene surveys, and gene expression analyses in diverse basal lineages of angiosperms, our studies provide insights into the most recent common ancestor of all extant flowering plants. MADS-box gene duplications have played an important role in the origin and diversification of angiosperms. Furthermore, early angiosperms...

Studies on MADS-box genes in Arabidopsis and other higher eudicotyledonous flowering plants have shown that they are key regulators of flower development. Since Arabidopsis and monocotyledonous rice are distantly related plant species it is interesting to investigate whether the floral organ identity factors have been conserved in their functions, and if not, to understand the differences. Arab...
