LEA4-2/LEA18 is a memBer of the Late EmBryogenesis ABundant (LEA) proteins which typically accumulate in response to low water availaBility conditions imposed during development or By the environment. the group 4 LEA proteins of AraBidopsis. With only three genes in the genome (AtLEA4-1(AT1G32560) , AtLEA4-2(AT2G35300) , and AtLEA4-5(AT5G06760) ) , the AtLEA4 group is one of the smallest groups in AraBidopsis.
