Expansins are a family of proteins that catalyze long-term extension of isolated cell walls. Previously, two expansin proteins have been isolated from internodes of deepwater rice, and three rice expansin genes, Os-EXP1, Os-EXP2, and Os-EXP3, have been identified. We report here on the identification of a fourth rice expansin gene, Os-EXP4, and on the expression pattern of the rice expansin gene family in deepwater rice. Rice expansin genes show organ-specific differential expression in the… Expand

TLDR
The results indicate that expansin transcripts and proteins play an important role in the expansion and differentiation of plant tissues and organs in deepwater rice. Expand
Expression of beta-expansins is correlated with internodal elongation in deepwater rice.
TLDR
It is concluded that the expression of beta-expansin genes is correlated with rapid elongation of deepwater rice internodes, it is induced by gibberellin and wounding, and wound-induced beta-Expansin mRNA appears to turn over rapidly. Expand
Expression of an Expansin Gene Is Correlated with Root Elongation in Soybean1 212
TLDR
The first root-specific expansin gene in soybean, GmEXP1, is identified, which may be responsible for root elongation, and transcripts were preferentially present in the epidermal cells and underlying cell layers in the root tip of the primary and secondary roots. Expand
Two expansins, EXP1 and EXPB2, are correlated with the growth and development of maize roots
TLDR
The results imply thatExpB2 plays a role in the elongation of maize roots, and may be also involved in plant responses to environmental stimuli. Expand
Expression of α-Expansin and Expansin-Like Genes in Deepwater Rice1
TLDR
Of the 22 additional α-expansin genes, five are expressed in internodes and leaves, three in coleoptiles, and nine in roots, with high transcript levels in the growing regions of these organs, the authors found no expression of the Os-EXPR1 gene in the organs examined. Expand
Expression of multiple expansin genes is associated with cell expansion in potato organs
TLDR
The data show that multiple α-expansin genes are expressed in expanding cells of potato tuber and stem tissues, and expression of at least some of these genes is hormonally regulated during growth. Expand
Localized Upregulation of a New Expansin Gene Predicts the Site of Leaf Formation in the Tomato Meristem
TLDR
A model for the regulation of phyllotaxis that postulates a crucial role for expansin in leaf primordium initiation is proposed, and LeExp18 expression is a molecular marker for leaf initiation, predicting the site ofPrimordium formation at a time before histological changes can be detected. Expand
Modification of expansin transcript levels in the maize primary root at low water potentials.
TLDR
Gene-specific regulation of alpha- and beta-expansin mRNA pools likely contributes to growth alterations of the maize (Zea mays) root as it adapts to a low psi(w), but these changes do not appear to be mediated by changes in ABA content. Expand
Limited correlation between expansin gene expression and elongation growth rate.
TLDR
The results show a strong correlation between expansin gene expression and growth rate, but this correlation is not absolute, and it is concluded that elongation growth is likely to be controlled by expansin acting in concert with other factors that may limit growth under some physiological conditions. Expand
Expression of three expansin genes during development and maturation of Kyoho grape berries.
TLDR
The findings suggest that the three expansin genes are associated with cell division or expansion and berry ripening, and Vlexp3, in particular, is most likely to play a role in grape berry softening at véraison. Expand

TLDR
The identification of a ripening-regulated expansin gene in tomato and other fruit suggests that, in addition to their role in facilitating the expansion of plant cells, expansins may also contribute to cell wall disassembly in nongrowing tissues, possibly by enhancing the accessibility of noncovalently bound polymers to endogenous enzymic action. Expand
Expansins and Internodal Growth of Deepwater Rice
TLDR
It is proposed that expansin is involved in mediating rapid internodal elongation in submerged deepwater rice internodes, and cell walls of submerged internodes extended much more in response to acidification than did the cells of air-grown internodes. Expand
Expansins in Deepwater Rice Internodes
TLDR
It is shown that two expansins occur in the cell walls of rice internodes and that they may mediate acid-induced wall extension and that the N-terminal amino acid sequence of SP20 and SP29 matches that deduced from the rice expansin cDNA Os-EXP2 in six of eight amino acids. Expand
Role of Expansin in Cell Enlargement of Oat Coleoptiles (Analysis of Developmental Gradients and Photocontrol)
TLDR
It is suggested that changes in the susceptibility of the wall to expansin action, rather than changes in expansin activity, may be a key determinant of the growth patterns in oat coleoptiles. Expand
On the role of abscisic Acid and gibberellin in the regulation of growth in rice.
TLDR
The results indicate that the growth rate of deepwater rice internodes is determined by the ratio of an endogenous growth promoter (GA) and a growth inhibitor (ABA), which may be related to the semiaquatic growth habit of this plant. Expand

TLDR
Comparison of expansin cDNAs from cucumber, pea, Arabidopsis and rice shows that the proteins are highly conserved in size and amino acid sequence, and suggests that this multigene family diverged before the evolution of angiosperms. Expand
Expansin Mode of Action on Cell Walls (Analysis of Wall Hydrolysis, Stress Relaxation, and Binding)
TLDR
It is concluded that expansins bind at the interface between cellulose microfibrils and matrix polysaccharides in the wall and induce extension by reversibly disrupting noncovalent bonds within this polymeric network. Expand
Role of gibberellin in the growth response of submerged deep water rice.
TLDR
Ethylene may cause internodal elongation in rice by increasing the activity of endogenous GAs in internodes from which the leaf sheath had been peeled off, and growth in response to submergence, ethylene and GA(3) was severely inhibited by light. Expand
Growth Maintenance of the Maize Primary Root at Low Water Potentials Involves Increases in Cell-Wall Extension Properties, Expansin Activity, and Wall Susceptibility to Expansins
TLDR
Assessment of the growth biophysics of maize primary roots suggests that cell walls in the apical 5 mm of the elongation zone increased their yielding ability as an adaptive response to low turgor and water potential ([psi]W), and that both the increase in expansin activity and the increased in cell-wall susceptibility to expansins play a role in enhancing cell- wall yielding and, therefore, in maintaining elongation. Expand
Autolysis and extension of isolated walls from growing cucumber hypocotyls.
TLDR
The results with exogenous enzymes suggest that the hydrolysis of matrix polysaccharides may not induce wall creep by itself, but may act synergistically with expansins to enhance wall extension. Expand
