Anthocyanidin reductase (ANR) is a key enzyme involved in the biosynthesis of proanthocyanidins (PAs) and plays a role in the plant stress response. However, the mechanism by which ANR confers stress tolerance in plants is not understood. Here, we report the isolation of RrANR, the homologous gene
Flavonoids play critical roles in plant responses to various stresses. Few studies have been reported on what the mechanism of activating flavonoid biosynthesis in plant responses to wounding and oxidation is. In this study, flavonoid metabolites and many MYB transcript factors from Rosa rugosa were
In this study, a gene with a full-length cDNA of 1422 bp encoding 473 amino acids, designated RrGT2, was isolated from R. rugosa 'Zizhi' and then functionally characterized. RrGT2 transcripts were detected in various tissues and were proved that their expression patterns corresponded with
The double-flower phenotype has been selected by humans for its attractiveness in various plant species and it is of great commercial value for the ornamental market. In this paper we investigated the genetic determinant of the dominant double-flower trait in carnation, petunia and Rosa rugosa,
We isolated AGAMOUS-like cDNA clones called MASAKO C1-C6 (C4-C6 are 3' or 5' partial cDNA clones) and MASAKO D1 from wild rose (Rosa rugosa Thunb. ex Murray). We found that MASAKO C1 was a homologue of AGAMOUS on the basis of sequence similarity, conservation of intron positions, and stamen- and
BACKGROUND
The advent of genomics-based technologies has revolutionized many fields of biological enquiry. However, chromosome walking or flanking sequence cloning is still a necessary and important procedure to determining gene structure. Such methods are used to identify T-DNA insertion sites and
Flower color is the main character throughout the plant kingdom. Though substantial information exists regarding the structural and regulatory genes involved in anthocyanin and flavonol biosynthesis, little is known that what make a diverse white vs. red color flower in natural species. Here, the
