Group II late embryogenesis abundant (LEA) proteins: structural and functional aspects in plant abiotic stress
2016
Banerjee, Aditya | Roychoudhury, Aryadeep
Group II late embryogenesis abundant (LEA) proteins are crucial phytomolecules which accumulate mainly in the late phases of seed development and also in the vegetative tissues in response to exogenous stress. In spite of considerable research, their mechanism of action to generate plant tolerance against abiotic stresses still remains obscure. The present review focuses on the varied structural aspects which ultimately dictate the multifarious functions of the Group II LEA proteins when the plants are exposed to intense desiccation. Currently, several reports have been documented regarding newer in silico approaches in predicting LEA protein structure and the corresponding cis-elements. Coupled to recent transgenic approaches, these reports need to be properly structured to further characterize the physico-chemical and functional importance of LEA proteins in regulating tolerance against multiple abiotic stresses.
