There are the five groups of late embryogenesis abundant (LEA) proteins found in plants
|
Group
(family name) |
Functional information |
|
I) Group 1 (D-19 family) |
a) It is an
abundant protein in cotton embryos, Each putative dimer of this group may
bind as many as ten inorganic phosphates and their counterions |
|
II) Group 2 (D-11 family) |
b) Possibly functions in ion
sequestration to protect cytosolic metabolism When LE25 is expressed in
yeast, it confers salt and freezing tolerance |
|
III) Group 3 (D-7 family) |
c) In tomato, a
gene encoding a similar protein is expressed in response to nematode feeding |
|
IV) Group 4 (D-95 family) |
d) Contains more
water of hydration than typical globular proteins Overexpression confers
water deficit tolerance on yeast cells |
|
V) Group 5 (D-113 family) |
e) Often
localized to the cytoplasm or nucleus More acidic members of the family are
associated with the plasma membrane May act to stabilize macromolecules at
low water potential |
