Transcriptomic analysis of Pak Choi under acute ozone exposure revealed regulatory mechanism against ozone stress.

ABSTRACT:

Background

Ground-level ozone (O₃) is one of the major air pollutants, which cause oxidative injury to plants. The physiological and biochemical mechanisms underlying the responses of plants to O₃ stress have been well investigated. However, there are limited reports about the molecular basis of plant responses to O₃. In this study, a comparative transcriptomic analysis of Pak Choi (Brassica campestris ssp. chinensis) exposed to different O₃ concentrations was conducted for the first time.

Results

Seedlings of Pak Choi with five leaves were exposed to non-filtered air (NF, 31 ppb) or elevated O₃ (E-O₃, 252 ppb) for 2 days (8 h per day, from 9:00-17:00). Compared with plants in the NF, a total of 675 differenti
