Transcriptomic response of maize primary roots to low temperatures at seedling emergence.

ABSTRACT:

Background

Maize (Zea mays) is a C₄ tropical cereal and its adaptation to temperate climates can be problematic due to low soil temperatures at early stages of establishment.

Methods

In the current study we have firstly investigated the physiological response of twelve maize varieties, from a chilling condition adapted gene pool, to sub-optimal growth temperature during seedling emergence. To identify transcriptomic markers of cold tolerance in already adapted maize genotypes, temperature conditions were set below the optimal growth range in both control and low temperature groups. The conditions were as follows; control (18 °C for 16 h and 12 °C for 8 h) and low temperature (12 °C for 16 h and 6 °C for 8 h). Four genotypes were identified from the conditio
