Expansins are unusual proteins discovered by virtue of their ability to mediate cell wall extension in plants. We identified cDNA clones for two cucumber expansins on the basis of peptide sequences of proteins purified from cucumber hypocotyls. The expansin cDNAs encode related proteins with signal peptides predicted to direct protein secretion to the cell wall. Northern blot analysis showed moderate transcript abundance in the growing region of the hypocotyl and no detectable transcripts in… Expand
Characterization and transcriptional expression of the alpha-expansin gene family in rice.
Diverse expression patterns of EXPA genes suggest that in general they have distinct roles in plant growth and development. Expand
Characterization and Transcriptional Expression of the α-Expansin Gene Family in Rice
The rice genome contains at least 28 EXPA (α-expansin) genes. We have obtained near full-length cDNAs from the previously uncharacterized genes. Analysis of these newly identified clones togetherExpand
Molecular characterization and transcriptome profiling of expansin genes isolated from Calotropis procera fibers
The lowest transcription of all the four Expansin A isoforms was observed in elongating roots indicating that root tissue might be having specific expansins other than those confined to air grown organs. Expand
Molecular cloning and expression of an expansin-like gene in ‘Navel’ orange fruit during postharvest stresses
Exposure of fruit to stresses, including wounding, anoxia, low temperature (4°C), and treatment with ethylene, increased CsEXP mRNA levels in comparison with the control untreated fruit, whereas high temperature (40°C) decreased its mRNA levels. Expand
Molecular cloning, characterization, and expression of a redox-responsive cutinase from Monilinia fructicola (Wint.) Honey.
Comparison of the deduced amino sequence from Mfcut1 with other fungal cutinase sequences revealed new features, which include conserved cysteines, C-terminal aromatic residues, and a novel histidine substitution in the D-H active site motif. Expand
Expansin-Like Molecules: Novel Functions Derived from Common Domains
It is argued that both irPNP- like molecules and expansin have evolved from primitive/ancestral glucanase-like molecules that hydrolysed the cell wall, indicating that these novel proteins specifically interact with the plasma membrane. Expand
Isolation and characterisation of two wheat β-expansin genes expressed during male gametophyte development
Two novel β-expansin genes, TaEX PB1 and TaEXPB2, were isolated from wheat microspores by suppression subtractive hybridisation and revealed that the isolated genes belong to a distinct group within the subfamily of β- expansion genes in the wheat genome. Expand
Large-scale EST sequencing in rice
The results obtained from the large-scale cDNA analysis provide useful information related to gene expression and regulation in rice, suggesting that around a half or one third of expressed genes in rice have already been captured. Expand
Plant Expansins Are a Complex Multigene Family with an Ancient Evolutionary Origin1
Based on phylogenetic analysis and shared intron patterns, a new, systematic nomenclature of Arabidopsis expansins is proposed, suggesting that the three plant expansin subfamilies arose and began diversifying very early in, if not before, colonization of land by plants. Expand
Wheat beta-expansin (EXPB11) genes: Identification of the expressed gene on chromosome 3BS carrying a pollen allergen domain
It is proposed that variations within the coding sequence of TaEXPB11 in wheats may produce a functional change within features such as domain 1 related to possible involvement in cell wall structure and domain 2 defining the pollen allergen domain and binding to IgE protein. Expand
