Title:
Abstract:
In response to environmental stresses, cytosolic calcium level
fluctuates and transduces signals to the target gene to endeavor stress and
identify the labor of division. Plant root architecture modulates during
developmental stages and adjusts with the environmental condition. Salt
strongly affects the root system in Arabidopsis
thaliana. CaCl2 supplemented as salt and cytosolic calcium is a
ubiquitous secondary messenger in all eukaryotes. We proposed that externally
applied calcium chloride gradients affect PIN2 expression which in term
modulates root architecture and lateral root emergence. This study found that
the abundance of PIN2 has a direct effect on the root curvature with respect to
CaCl2 gradient. In the presence of low concentration of CaCl2,
stabilized PIN2 protein and subsequent accumulation lead to straight root
architecture. However, as the CaCl2 concentration were increased,
PIN2 protein destabilized and subsequently degraded which in turn showed a wavy
root phenotype. On the other hand, different concentrations of CaCl2 did not show any effect on PIN2 gene
at transcript level. In the present study, the roots of overexpressing PIN2 and
mutant Arabidopsis thaliana were
investigated on CaCl2 salt.
Biography:
Dr. Mohammad Nisar is an associate
professor and Chairman at Department of Botany, University of Malakand. He has
published over 60 papers and book chapters in well reputed journals. He is a
recognized expert in the field of protein interactions, CRISPR, genetic
diversity, etc. Currently, he is working on molecular
tools that can be used to investigate the interaction of GI with PKS gens under
a-biotic stresses. He obtained Bachelor Degree in Botany from University of Peshawar, KPK,
Pakistan in 2002. From 2002 to 2010, he went to Quaid-i-Azam University and
completed his MPhil in Plant Sciences. In 2005-2009, he conducted his research
work on Genetic diversity in Pisum
sativum and obtained his PhD in 2009. In 2012, he worked as a postdoctoral
researcher at Gyeongsang National University,
Jinju City, Korea.
He supervised 4 PhD’s and 11 MPhil students.
