Abstract

DOR: 98.1000/1735-0891.1397.2.244.52.26.1575.41

Salinity is one of the main environmental factors limiting production and distribution of
plants worldwide. Aegilops is a wild species from grasses family with useful genes such as
environmental stress tolerance. Two genotypes, 575 from Aegilop cylindrica as resistant and
675 from Aegilop crassa as sensitive to salinity were used base on previous experiments in
salinity stress. After seed germination, the seedlings were transferred to a sandy environment
under controlled light and temperature conditions and irrigation was performed under two
normal conditions and 200 mM salinity with Hoagland solution. Leaf tissue samples were taken
at 0, 6, 24, 48 and 72 hours after salinity treatments. After extracting the RNA and the cDNA
synthesis, its accuracy was verified by 18S rRNA. The expression of the three transcription
factors of CBF14, NAC2 and MYB was investigated by using Real Time-PCR. Results showed
that NAC2 and CBF14 transcription factors had the highest expression at 48 hours after salinity
stress, but the MYB gene had the highest expression at 24 hours after stress. Overall, the
expression of CBF14, NAC2, and MYB genes in the 575 genotype compared with genotype 675
was in higher level in all hours. The results showed that the three mentioned genes play
important role in salt tolerance in the tolerant genotype, therefore, considering the high genetic
similarity between Aegilops and wheat, the genes can be as candidate genes for using in wheat
breeding programs.
