Expansins are proteins which have been demonstrated to induce cell wall extension in vitro. The identification and characterization of six expansin cDNAs from strawberry fruit, termed FaExp3 to FaExp7, as well as the previously identified FaExp2 is reported here. Analysis of expansin mRNAs during fruit development and in leaves, roots and stolons revealed a unique pattern of expression for each cDNA. FaExp3 mRNA was present at much lower levels than the other expansin mRNAs and was expressed in… Expand
Expression of expansin genes in strawberry varieties with contrasting fruit firmness.
TLDR
Western-blot analysis revealed that the accumulation of expansin proteins begins earlier in the softest cultivar during ripening, and a correlation between mRNA expression levels and fruit firmness for FaEXP1, FaEXP2 and FaEXP5 is found. Expand
Identification of a new expansin gene closely associated with peach fruit softening
TLDR
While several expansins show a general increase in expression levels during the later stages of fruit development, some isoforms show a greater association with softening than others and PpExp3 is more likely to play a role in peach fruitSoftening. 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
Differential expression of seven α‐expansin genes during growth and ripening of pear fruit
TLDR
It is demonstrated that characteristically, multiple expansin genes show differential expression and hormonal regulation during pear fruit development and at least six expansins show overlapping expression during ripening. Expand
Influence of plant growth regulators on Expansin2 expression in strawberry fruit. Cloning and functional analysis of FaEXP2 promoter region
TLDR
Histochemical GUS staining analysis showed that the 650 bp-promoter fragment was able to drive the reporter gene expression specifically to the receptacle and along ripening, providing new insights into the hormonal regulation of FaEXP2 expression. Expand
Molecular and structural insights into FaEXPA5, an alpha-expansin protein related with cell wall disassembly during ripening of strawberry fruit.
TLDR
The full length of this α-expansin (FaEXPA5), whose had been related with fruit softening, is reported and the protein structural was described by homology model, and MD simulations showed that FaEXPA 5 can interact with the ligands through residues present in the open groove along the two domains.

Multiple forms of α-expansin genes are expressed during banana fruit ripening and development
TLDR
It is concluded that expression of multiple expansin genes might be required for softening not only in dicot fruit such as pear, apple and strawberry but also in monocot Fruit such as banana. Expand
Expression of five expansin genes during softening of Fragaria chiloensis fruit: Effect of auxin treatment
TLDR
Most of the strawberry-expansin genes are expressed in F. chiloensis and some family members are closely related to fruit softening, especially FaEXP2 and FaEXP5, but the repressive effect of auxins on the expression of those expansin genes related to softening in F. Expand
Coffea expansin gene family and expansin expression during fruit maturation.
Expansins (EXP) are plant cell-wall loosing proteins involved in cell enlargement and developmental process such as organogenesis, seeds germination, cell wall dissolution and fruit ripening. TwoExpand
MaExp1, an ethylene-induced expansin from ripening banana fruit
TLDR
It is suggested that MaExp1 could be used for manipulating ripening in banana and its promoter could be a suitable candidate for expressing foreign gene (vaccines) in transgenic banana fruit. 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
An expansin gene expressed in ripening strawberry fruit.
TLDR
The results suggest that expansins are a common component of ripening and that non-climacteric signals other than auxin may coordinate the onset of ripens in strawberry. Expand
Expression of expansin genes is correlated with growth in deepwater rice.
TLDR
The results indicate that the expression of expansin genes in deepwater rice is differentially regulated by developmental, hormonal, and environmental signals and is correlated with cell elongation. Expand
Isolation of a set of ripening-related genes from strawberry: their identification and possible relationship to fruit quality traits
TLDR
The role of specific genes involved in key metabolic events including anthocyanin biosynthesis, cell wall degradation, sucrose and lipid metabolism, protein synthesis and degradation, and respiration are discussed in relation to the role of these genes in determining fruit quality characteristics.

Modification of Expansin Protein Abundance in Tomato Fruit Alters Softening and Cell Wall Polymer Metabolism during Ripening
TLDR
Investigation of suppression and overexpression of Exp1 in transgenic tomato plants found fruit overexpressing high levels of recombinant Exp1 protein were much softer than controls, even in mature green fruit before ripening commenced, consistent with there being at least three components to fruit softening and textural changes.

Two Different Endo-β-1,4-Glucanases Contribute to the Softening of the Strawberry Fruits
TLDR
The fine structure of the cell wall weakening which occurs during the ripening is well in accordance with the above described biochemical and molecular data. Expand
Characterization of two divergent endo-beta-1,4-glucanase cDNA clones highly expressed in the nonclimacteric strawberry fruit.
TLDR
The high levels of Cel1 and Cel2 mRNA in ripe fruit and their overlapping patterns of expression suggest that these EGases play an important role in softening during ripening, and the early expression of Cel2 in green fruit, well before significant softening begins, suggests that the product of this gene may also be involved in processes other than fruit softening, e.g. cell wall expansion.

Expansins in plant growth and development: an update on an emerging topic
TLDR
Other recent advances in expansin research include the recovery of transgenic plants with altered level of expansins, and the production of recombinant expansins in het-erologous expression systems. Expand
Molecular cloning and sequence analysis of expansins--a highly conserved, multigene family of proteins that mediate cell wall extension in plants.
TLDR
The high conservation of this multigene family indicates that the mechanism by which expansins promote wall extensin tolerates little variation in protein structure. Expand
Two endogenous proteins that induce cell wall extension in plants.
TLDR
It is found that a crude protein extract from the cell walls of growing cucumber seedlings possessed the ability to induce the extension of isolated cell walls and these proteins appear to mediate "acid growth" responses of isolated walls and may catalyze plant cell wall extension by a novel biochemical mechanism.
