| Description |
The present work was conducted to understand the basis of adaptation in Caragana jubata in its niche
environment at high altitude cold desert of Himalaya. Molecular data showed predominance of genes
encoding chaperones and those involved in growth and development at low temperature (LT), a major cue
operative at high altitude. Importantly, these genes expressed in C. jubata in its natural habitat. Their
homologues in Arabidopsis thaliana, Oryza sativa, and Glycine max did not exhibit similar trend of gene
expression at LT. Constitutive expression and a quick up-regulation of the above genes suggested the ability
of C. jubata to adjust its cellular machinery to maintain growth and development in its niche. This was
reflected in LT50 (the temperature at which 50% injury occurred) and LT mediated photosynthetic
acclimatory response. Such molecular and physiological plasticity enables C. jubata to thrive in the high
altitude cold desert of Himalayas.
