MYB transcription factors (TFs) make up one of the most important TF families in plants. These proteins play crucial roles in processes related to development, metabolism, and stimulus-response; however, very few studies have been reported for the characterization of MYB TFs from banana. The current
Background: Pollen formation and development is important for crop fertility and is a key factor for hybrid development. Previous reports have indicated that Arabidopsis thaliana TAPETUM DETERMINANT1 (AtTPD1) and its rice (Oryza sativa)
BACKGROUND
Many commercial banana varieties lack sources of resistance to pests and diseases, as a consequence of sterility and narrow genetic background. Fertile wild relatives, by contrast, possess greater variability and represent potential sources of disease resistance genes (R-genes). The
Seagrasses are flowering plants which grow fully submerged in the marine environment. They have evolved a range of adaptations to environmental challenges including light attenuation through water, the physical stress of wave action and tidal currents, high concentrations of salt, oxygen deficiency
Each year brings new facts concerning multiple roles of sugar pathways in plant metabolism. One of them--the trehalose pathway--has been shown to play a role in stress signalling. The last enzyme of this pathway--trehalase--has been proven to be strongly expressed in guard cells. Modifications of
Organellar DNA in mature pollen grains of eight angiosperm species (Actinidia deliciosa Lindl., Antirrhinum majus L., Arabidopsis thaliana (L.) Heynh., Medicago sativa L., Musa acuminata Colla, Pelargonium zonale (L.) L'Hér, Petunia hybrida Vilm. and Rhododendron mucronatum (Blume) G. Don, in which
The Nictaba family groups all proteins that show homology to Nictaba, the tobacco lectin. So far, Nictaba and an Arabidopsis thaliana homologue have been shown to be implicated in the plant stress response. The availability of more than 50 sequenced plant genomes provided the opportunity for a
The diacylglycerol acyltransferases (DGAT) (diacylglycerol:acyl-CoA acyltransferase, EC 2.3.1.20) are a key group of enzymes that catalyse the final and usually the most important rate-limiting step of triacylglycerol biosynthesis in plants and other organisms. Genes encoding four distinct
