2. Materials and Methods
2.1. Plant Material. In the first part of this study, variations
on the Sl-ERF.B.3 gene expression under five types
of abiotic stresses (salinity, drought, flooding, heat, and
cold) were investigated, based on wild type tomato plants
(Solanum lycopersicum cv. MicroTom). In the second part
of this work we focused on the tomato plant responses to
salt and cold stresses. For this purpose, in addition to the
investigated wild type tomato, two homozygous independent
antisense transgenic tomato lines (Sl-ERF.B.3.AS42 and Sl-
ERF.B.3.AS38) (provided by the Laboratory of Genomic and
Fruit Biotechnology, UMR990 INRA/INP-ENSA Toulouse,
France) were included in this part of our study.
