Quantitative changes in DNA methylation induced by monochromatic light in barley regenerants obtained by androgenesis

Biuletyn Instytutu Hodowli i Aklimatyzacji Roślin (2020)

Patrycja Siedlarz Sławomir Bany Krystyna Rybka

Changes in DNA methylation are one of the best known mechanisms of epigenetic regulation of gene expression, which in the process of induced androgenesis is associated with reprogramming of haploid microspores development towards the formation of embryos, as a result of exposure of anthers in ears and then anthers culture in vitro to stress factors. The aim of the study was to test the hypothesis of whether the use of monochromatic light during induced androgenesis might be associated with epigenetic phenomena. The experiments were carried out on DH plants of spring barley (Hordeum vulgare L.) obtained by androgenesis modified by monochromatic light: blue, green and red. A quantitative evaluation of the effect of light on the degree of DNA methylation was performed using RP-HPLC for the comparison of regenerants obtained under standard, control conditions (darkness) with those obtained with light usage. The differences in the amount of methylated cytidine in comparison to the control were: 0.40%, 0.16% and -0.55%, for blue, red and green light, respectively. The level of global genomic DNA methylation from control plants was in the range 21.32-21.52%. Methylation changes in response to monochromatic light used during callus formation in anthers culture, determined by RP-HPLC, are significant although small.

The 4R QTLs pollen fertility restoration in triticale with CMS Triticum timopheevii

Crop Science (2022)

Abstract The Triticum timopheevii Zhuk. ( Tt ) cytoplasm is the most exploited cytoplasmic male sterility (CMS) type used in triticale in commercial seed production of hybrid varieties. The present study established a recombinant inbred line (RIL) mapping population to identify genetic loci controlling fertility restoration in triticale with CMS Tt . The trait was evaluated via phenotyping the BC 1 F 1 materials originating from a backcross of maternal line MS 112(15)‐2‐1 (on CMS Tt ) and RILs. A genetic map spanning 2293 cM over 21 linkage groups was constructed using 1,170 single nucleotide polymorphisms and silico diversity array technology (DArT) markers generated through DArTseq genotyping. Two quantitative trait loci (QTL) controlling fertility restoration were localized at the 4RL chromosome. They were stable during two vegetative seasons and, depending on the year, explained 17.8 to 37.5 ( QRft‐4R.1 ) and 17.8 to 27.1% ( QRft‐4R.2 ) of phenotypic variance. Bioinformatic analysis was performed to predict genes potentially responsible for the trait. Four markers linked to the trait were successfully converted into a polymerase chain reaction‐based assay to select the pollen fertility QTLs easily. The exact position of QTLs detected previously in the rye and here in the triticale suggests that the same loci might control the trait.
