“…The 60 TFs with enriched targets in the HVGs are mainly part of the NAC, bZIP and MYB-related families and these families are more represented in this set than expected based on the entire DAP-seq dataset (Fig 3C). NAC TFs have been suggested to play important roles in the regulation of the transcriptional reprogramming associated with plant stress responses 26 , MYB-related TFs are involved in anthocyanin biosynthesis and the circadian clock 27 and bZIP TFs regulate multiple processes including pathogen defence, light and stress signalling, seed maturation and flower development 28 . These are in agreement with the enriched GOs identified for HVGs, involved in responses to the environment as well as biotic and abiotic stresses.…”

“…MYB transcription factors are coded by an ancient and highly conserved gene family, and play a number of roles in plant growth and development (Nguyen and Lee, 2016). Many MYB transcription factors have been shown to participate in the regulation of trichomes and root-hair, with positive or negative regulatory functions (Wang and Chen, 2014).…”

Trichomes are derived from the epidermis and constitute an ideal system for studying cell division in plants. Here, a Chinese cabbage doubled haploid (DH) line (FT) without trichomes was crossed with another DH line (PurDH-1) with trichomes to develop an F population for fine mapping of trichome control genes. Genetic analysis showed that the trichome phenotype was controlled by a single dominant gene, Brtri1. Using 1226 glabrous individuals in the F segregation population, Brtri1 was localized to a 16.84 kb region between markers Pur6-31 and Pur6-39 on chromosome A06. One of the four complete open reading frames within the mapping region, Bra025311, encodes a MYB transcription factor and is highly homologous to the trichome regulatory gene GL1 in Arabidopsis thaliana. It was thus regarded as a candidate gene for Brtri1. Comparative sequencing showed a 5-bp deletion in the third exon of Bra025311 in FT, resulting in a frame-shift mutation. No expression of Bra025311 was detected in FT. A co-dominant indel marker close to this mutation site was developed for marker-assisted selection in Chinese cabbage breeding.

“…One hundred milligram fresh leaves of each sample were collected and ground in liquid nitrogen. RNA was extracted from the ground samples using the TRIzol method and was reverse synthesized to cDNA using the Thermo Scientific RevertAid first strand cDNA synthesis kit [36,48]. qRT-PCR analyses were conducted using a Bio-Rad Thermocycler.…”

Aegilops tauschii (Ae. tauschii) is a diploid (2n = 2x = 14) wild grass species, which has been reported as the progenitor of hexaploid wheat (Triticum aestivum) with D-genome. In this study, 68 Ae. tauschii accessions with diverse geographical backgrounds were investigated for their resistance to infection by the leaf rust fungi Puccinia triticina. Two Ae. tauschii accessions that exhibited hyper-resistance to leaf rust at both seedling and adult stages were identified. Utilizing two susceptible Ae. tauschii ecotypes and keumkang, a common Korean wheat cultivar known to be susceptible to leaf rust, as the negative control, further investigations were conducted for understanding the mechanism underlying immunity to leaf rust disease of these two resistant accessions. Resistant accessions displayed the increased β-1,3-glucanase activity to prevent fungal penetration and the better peroxidase activity to cope with leaf rustinduced oxidative stress. Moreover, transcriptional analyses reveal the important role of the LRR receptor-like serine/ threonine-protein kinase FLS2 (lrr) to the disease resistance of the two ecotypes. Ae. tauschii is a remarkable genetic source, especially for abiotic and biotic stress resistance genes, as the plant is known for its wide-ranging geographical habitat and adaptability to different environments. This, combined with the fact that Ae. tauschii and wheat share a close evolutionary relationship, is indicative of the immense benefit of using Ae. tauschii as a material for improving the quality of synthetic wheat. Our aim was to identify and evaluate the strongest Ae. tauschii contenders for breeding leaf rust-resistant synthetic wheat.
