Morphological trait variations in four populations of Arabidopsis thaliana that grow along altitudinal gradients (~700 to ~3500 m amsl) are described. A total of 38 traits were analysed from each of the four populations. Most of the quantitative traits were significantly correlated with each other among the four populations, but biomass-related traits were negatively correlated with altitude. There was significant correlation between geographical distance and mean pairwise distance of phenotypic traits among the populations. Overall our data suggest there is significant variation in phenotypic traits of the four populations along altitudinal gradients.

Abstract


Morphological trait variations in four populations of Arabidopsis thaliana that grow along altitudinal gradients (~700 to ~3500 m amsl) are described. A total of 38 traits were analysed from each of the four populations. Most of the quantitative traits were significantly correlated with each other among the four populations, but biomass-related traits were negatively correlated with altitude. There was significant correlation between geographical distance and mean pairwise distance of phenotypic traits among the populations. Overall our data suggest there is significant variation in phenotypic traits of the four populations along altitudinal gradients.
