“…Near-isogenic lines and modern DNA-based genotyping approaches provide a powerful means of chromosome localization and fi ne mapping of genes with unstable expression. Using this approach we localized recently the gene Ra-D1 in a vicinity of Rc-D1 on chromosome 7DS (Khlestkina et al 2014 ). There is a good agreement between our data and that reported by Jha ( 1971 ).…”

“…The ratios Chl ( a + b ):Car and Chl a :Chl b were calculated. Additionally, the relative content (%) of the non-photosynthetic anthocyanin pigments was also recorded measuring the absorbance at 530 nm using the same spectrophotometer ( Mancinelli et al 1975 ; Khlestkina et al 2014 ). Anthocyanin accumulation may provide antioxidant and photoprotection functions, and act as a dehydration-tolerance mechanism under salt stress ( Chalker-Scott 1999 ; Lee and Collins 2001 ; Gould et al 2002 ).…”

Phenotypic plasticity of polyploid plant species promotes transgressive behaviour in their hybrids

Hybridization is a frequent process that leads to relevant evolutionary consequences, but there is a lack of studies regarding the relationships of the variability of the response of parental plant species to environmental gradients and the responses of their hybrids at a phenotypic level. We designed an experiment in which we exposed two reciprocal cordgrass hybrids, Spartina maritima × densiflora and S. densiflora × maritima, and their parental species to four salinity concentrations for 30 days. The main objectives were to compare the performance of the hybrids with that of their parents, to distinguish the phenotypic inheritance operating in the hybrids and to analyse the relationships between the variability in the responses of the parents and the responses of their hybrids to salinity. We characterized the responses and the degree of variability for 37 foliar traits. Both hybrids presented greater salinity tolerance than their parents, showing their highest percentage of transgressive traits at both extremes of the salinity gradient. When the parental plants themselves showed a more plastic response for a given trait, there was a greater chance that their hybrid developed a transgressive behaviour for this trait. This finding supports a new focus to be applied for the artificial development of vigorous hybrid crops.

“…The anthocyanin pigmentation in wheat is controlled by dominant alleles of the genes Rc (coleoptile), Pc (culm), Plb (leaf blades), Pls (leaf sheaths), Pp (grain pericarp), Pan (anthers), and Ra (auricles) [6][7][8][9][10]. The alleles conferring strong pigmentation induce more intensive transcription of the structural genes, proving their role as regulators in the anthocyanin biosynthesis network.…”

Breeding programs for purple wheat are underway in many countries but there is a lack of information on the effects of Pp (purple pericarp) genes on agronomic and quality traits in variable environments and along the product chain (grain-flour-bread). This study was based on unique material: two pairs of isogenic lines in a spring wheat cv. Saratovskaya-29 (S29) background differing only in Pp genes and grain color. In 2017, seven experiments were conducted in Kazakhstan, Russia, and Turkey with a focus on genotype and environment interaction and, in 2018, one experiment in Turkey with a focus on grain, flour, and bread quality. The effect of environment was greater compared to genotype for the productivity and quality traits studied. Nevertheless, several important traits, such as grain color and anthocyanin content, are closely controlled by genotype, offering the opportunity for selection. Phenolic content in purple-grained lines was not significantly higher in whole wheat flour than in red-colored lines. However, this trait was significantly higher in bread. For antioxidant activities, no differences between the genotypes were detected in both experiments. Comparison of two sources of Pp genes demonstrated that the lines originating from cv. Purple Feed had substantially improved productivity and quality traits compared to those from cv. Purple.
