Genes responding to O3 are regulated during leaf development in hybrid poplar (Populus tremula x alba)
Listed in NCBI GEO
Tropospheric ozone (O3) harms vegetation by reducing tree biomass and crop yield.
Description
Accurate risk assessment based on O3 uptake depends on quantifying the plant's capacity to cope with O3-generated reactive oxygen species (ROS) at the cellular level. Young leaves were shown to have better ability to deal with O3 stress than mature leaves but the mechanisms behind remain unclear.
The aim of this study was to assess the crosstalk between O3 response and leaf development process. Time-course response to O3 (80 and 100 ppb) was studied at transcriptomic and cellular level in a growing leaf (GL) and an expanded leaf (EL) of young poplar. Quantification of hypersensitive response-like (HR-like) and chlorophyll showed that GL was more tolerant to O3 than EL.

The response of leaf transcriptome to O3 concerns mostly genes regulated at the developmental level leading to an acceleration of leaf aging and senescence. GL response to O3 was delayed compared to EL suggesting that O3 tolerance at early stages of leaf development may result from an insensitivity to O3-induced senescence. In addition to detoxification mechanisms, understanding this process could offer new perspectives for O3 tolerance improvement or assessment.
