“…Moreover, other authors Bartels and Sunkar (2005); Wang et al (2006) and; Morran et al (2011) studies indicated that other elements play a pivotal role in cellular protection and stress alleviation such as dehydrins, molecular chaperones, water channel proteins, transporters and biosynthetic enzymes, growth regulators, protein phosphates, phospholipid metabolic proteins and protein kinases . In Eucalyptus, extensive studies on morpho-physiological and biochemical response to water stress condition is reported, while molecular response is limited to transcriptome-wide response in E. globulus and E. cladocalyx (Spokevicius et al, 2017), E. camaldulensis (Thumma et al, 2012), E. alba hybrid and E. urophylla × E.grandis (Villar et al, 2011), and E. grandis (Ghosh Dasgupta and Dharanishanthi, 2017). In this genus, the major transcription factors which regulate water stress include zinc finger transcription factor family protein (Villar et al, 2011), such as MYB, NAC, ERF, HB12 (Thumma et al, 2012) and HSFs, DREB2A, DEAR3 (Ghosh Dasgupta and Dharanishanthi, 2017).…”
