There are the five groups of late embryogenesis abundant (LEA) proteins found in plants

Match the following groups of LEA protein with its functional information;

 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
