Genetic effect on phytoaccumulation of arsenic in Brassica juncea L
The presence of excessive amounts of heavy metals such as arsenic in the environment is a problem in many parts of the world. Many countries e.g. Bangladesh are already severely affected by arsenic contamination of soil and groundwater. Phytoaccumulation is a method in which plants are used to uptake heavy metals from soil. The genus Brassica has many species that can efficiently accumulate arsenic. Despite many studies on phytoaccumulation, little is known about the genetics of phytoaccumulation of Brassica these species. This study investigated the genetic effect on phytoaccumulation of arsenic in Brassica juncea L. and attempted to identify any morphological trait(s) for phytoaccumulation. Two cultivars of B. juncea cvs. Rai and BARI-11 and a set of their morphological characteristics were selected to evaluate their potential as marker(s) for phytoaccumulation. A single concentration, 15 ppm of arsenic was used to study the genetic effect on phytoaccumulation using quantitative genetics. The results revealed that phytoaccumulation of arsenic (by the root and shoot systems) is heritable in the broadsense and polygenic in nature. The stem diameter was also found to be heritable in the broadsense and path analysis indicated that it has a significant direct effect on the shoot uptake. It is concluded that phytoaccumulation of arsenic in B. juncea (cvs. Rai and BARI-11) is a genetic phenomenon and stem diameter may be a potential marker of phytoaccumulation of arsenic in B. juncea (cvs. Rai and BARI-11)

Abstract

The presence of excessive amounts of heavy metals such as arsenic in the environment is a problem in many parts of the world. Many countries e.g. Bangladesh are already severely affected by arsenic contamination of soil and groundwater. Phytoaccumulation is a method in which plants are used to uptake heavy metals from soil. The genus Brassica has many species that can efficiently accumulate arsenic. Despite many studies on phytoaccumulation, little is known about the genetics of phytoaccumulation of Brassica these species. This study investigated the genetic effect on phytoaccumulation of arsenic in Brassica juncea L. and attempted to identify any morphological trait(s) for phytoaccumulation. Two cultivars of B. juncea cvs. Rai and BARI-11 and a set of their morphological characteristics were selected to evaluate their potential as marker(s) for phytoaccumulation. A single concentration, 15 ppm of arsenic was used to study the genetic effect on phytoaccumulation using quantitative genetics. The results revealed that phytoaccumulation of arsenic (by the root and shoot systems) is heritable in the broadsense and polygenic in nature. The stem diameter was also found to be heritable in the broadsense and path analysis indicated that it has a significant direct effect on the shoot uptake. It is concluded that phytoaccumulation of arsenic in B. juncea (cvs. Rai and BARI-11) is a genetic phenomenon and stem diameter may be a potential marker of phytoaccumulation of arsenic in B. juncea (cvs. Rai and BARI-11)
