Nonsense mutation of an MYB transcription factor is associated with purple-blue flower color in soybean.

Previous studies revealed that the recessive allele of the W2 locus generated purple-blue color and high vacuolar pH of flower petals in soybean. The location of W2 gene was reportedly close to simple sequence repeat marker Satt318 in molecular linkage group B2. We used information from the soybean genome to clone a candidate gene for W2. An MYB transcription factor gene belonging to G20 group ...

The Arabidopsis ATR1 Myb transcription factor controls indolic glucosinolate homeostasis.

Plants derive a number of important secondary metabolites from the amino acid tryptophan (Trp), including the growth regulator indole-3-acetic acid (IAA) and defense compounds against pathogens and herbivores. In previous work, we found that a dominant overexpression allele of the Arabidopsis (Arabidopsis thaliana) Myb transcription factor ATR1, atr1D, activates expression of a Trp synthesis ge...

Study of MYB Transcription Factor Gene Expression in Some Bread Wheat Cultivars of Sistan Region, Iran

Drought, an abiotic stress, considered as one of the factors limiting food resources. The plant responses to adaptive to such a condition are accompanied with changes in the expression pattern of some functional as well as regulatory genes. The MYB proteins include a big family of transcription factors which are highly important in regulating development process and immunizing responses of plan...

Isolation and characterization of GmMYBJ3, an R2R3-MYB transcription factor that affects isoflavonoids biosynthesis in soybean

Isoflavonoids are secondary metabolites that play a variety of roles in plant-microbe interactions and plant defenses against abiotic stresses. Here we report a new MYB transcription factor (TF) gene, GmMYBJ3, that is involved in the isoflavonoids biosynthesis. The GmMYBJ3 gene is 1,002 bp long and encodes a protein of 333 amino acids. Amino acid sequence analysis showed that GmMYBJ3 is a typic...

An R2R3-type MYB transcription factor, GmMYB29, regulates isoflavone biosynthesis in soybean

Isoflavones comprise a group of secondary metabolites produced almost exclusively by plants in the legume family, including soybean [Glycine max (L.) Merr.]. They play vital roles in plant defense and have many beneficial effects on human health. Isoflavone content is a complex quantitative trait controlled by multiple genes, and the genetic mechanisms underlying isoflavone biosynthesis remain ...
