Özet

Maternal effects are ubiquitous in nature and have been demonstrated in a wide array of traits and taxa. In many species, the genotype of the mother is a major determinant of the phenotype of her offspring. In plants, less is known about the levels of sensitivity to stresses-mediated maternal effects. We generated 12 reciprocal crossed F2 lines from two salt-tolerant and two salt-sensitive wheat cultivars to distinguish the influence of the maternal effect from the influence of the offspring genome on the expression of offspring traits under high-salinity (250 mM NaCl). SSR markers screening of the reciprocal hybrid genotypes and parents' nuclear genomes and Sanger sequencing of low-, medium-, and high-dominant markers revealed insignificant changes in the nuclear genome among offspring and parents. However, interestingly, the offspring with salt-tolerant mothers showed higher salt tolerance than those with salt-sensitive mothers. This study shed light on still unresolved fundamental questions regarding the potential of maternal genetic effects contribute to stress tolerance and the noncompletely control by nuclear genetic factors, which may open future research avenues as a source of a quality shift in subsequent offspring that any genetic analysis of tolerance traits must consider.
