Cold tolerance in the genus Arabidopsis.

ABSTRACT:

Premise

Cold tolerance is an important factor limiting the geographic distribution and growing season for many plant species, yet few studies have examined variation in cold tolerance extensively within and among closely related species and compared that to their geographic distribution.

Methods

This study examines cold tolerance within and among species in the genus Arabidopsis. We assessed cold tolerance by measuring electrolyte leakage from detached leaves in multiple populations of five Arabidopsis taxa. The temperature at which 50% of cells were lysed was considered the lethal temperature (LT₅₀ ).

Results

We found variability within and among taxa in cold tolerance. There was no significant within-species relationship between latitude and cold toleranc
