Late embryogenesis abundant protein 18 This is a family of late embryogenesis-abundant proteins There is high accumulation of this protein in dry seeds, and in the roots of full-grown plants in response to dehydration and ABA (abscisic acid application) treatments. This LEA protein disappears after germination. It accumulates in growing regions of well irrigated hypocotyls and meristems suggesting a role in seedling growth resumption on rehydration. As a group the LEA proteins are highly hydrophilic, contain a high percentage of glycine residues, lack Cys and Trp residues and do not coagulate upon exposure to high temperature, and for these reasons are considered to be members of a group of proteins called hydrophilins. Expression of the protein is negatively regulated during etiolating growth, particularly in roots, in contrast to its expression patterns during normal growth. |
