The present work was conducted to understand the basis of adaptation in Caragana jubata its niche environment at high altitude cold desert Himalaya. Molecular data showed predominance genes encoding chaperones and those involved growth development low temperature (LT), a major cue operative altitude. Importantly, these expressed C. natural habitat. Their homologues Arabidopsis thaliana, Oryza sativa, Glycine max did not exhibit similar trend gene expression LT. Constitutive quick up-regulation above suggested ability adjust cellular machinery maintain niche. This reflected LT(50 )(the which 50% injury occurred) LT mediated photosynthetic acclimatory response. Such molecular physiological plasticity enables thrive Himalayas.
