“…JA is widely involved in biotic stresses in plants. LOX genes were found to be induced after aphid infestation in plants [44,45], while OsHI-LOX in rice [14], TomloxD in tomato [15], and ZmLOX10 in maize [16] all play positive roles during plant defense against biotic stresses due to JA biosynthesis. In barley, the overexpression of LOX2.2 maintained lower aphid numbers, and antisense plants had higher aphid numbers [17].…”

Lipoxygenases (LOX) play pivotal roles in plant resistance to stresses. However, no study has been conducted on LOX gene identification at the whole genome scale in rose (Rosa chinensis). In this study, a total of 17 RcLOX members were identified in the rose genome. The members could be classified into three groups: 9-LOX, Type I 13-LOX, and Type II 13-LOX. Similar gene structures and protein domains can be found in RcLOX members. The RcLOX genes were spread among all seven chromosomes, with unbalanced distributions, and several tandem and proximal duplication events were found among RcLOX members. Expressions of the RcLOX genes were tissue-specific, while every RcLOX gene could be detected in at least one tissue. The expression levels of most RcLOX genes could be up-regulated by aphid infestation, suggesting potential roles in aphid resistance. Our study offers a systematic analysis of the RcLOX genes in rose, providing useful information not only for further gene cloning and functional exploration but also for the study of aphid resistance.

“…We identified three genes TraesCS3D02G075600, TraesCS-3D02G085400LC and TraesCS3D02G087600 on 3D, which are different from the candidate genes of QSa3.haust-3D. Some other candidate genes were identified, including Hpa1 [10], SaEST1 and SaEST2 [37], six TaLOXs [38], three TaMYBs [39], related genes PP2s and GSLs [10,39] and a gene TtLOX, which was cloned [17]. Their annotations are different from the candidate genes in this study.…”

“…Luo et al [37] found that the expression levels of the candidate genes SaEST1 and SaEST2, which are the putative photosystem I assembly protein Ycf3 and vegetative cell wall gp1-like protein, respectively, up-regulated the EGA resistance in flag leaves. Wang et al [38] identified lipoxygenase linoleate (LOX) genes, TaLOX5, 7, 10, 24, 29, 33, specifically expressed post-EGA infestation using RNA-seq data and qRT-PCR analysis. Zhai et al [39] elucidated that the TaMYB19, TaMYB29 and TaMYB44 are co-regulators of wheat plant phloem-based defence (PBD) using qRT-PCR and the gene silencing method.…”

The English grain aphid (EGA) (Sitobion avenae F.) is one of the most destructive species of aphids in wheat- (Triticum aestivum L.) planting areas worldwide. Large quantities of insecticides are usually used to control aphid damage. The identification of new EGA-resistant genes is necessary for sustainable wheat production. The objective of this study was to identify candidate genes for EGA resistance from stable quantitative trait loci (QTLs). We previously constructed a genetic map of unigenes (UG-Map) with 31,445 polymorphic sub-unigenes via the RNA sequencing of ‘TN18 × LM6’ recombinant inbred lines (TL-RILs). The relative aphid index (RAI) for the TL-RILs was investigated for two growing seasons, with three measured times (MTs) in each season. Using the UG-Map, 43 candidate genes were identified from 22 stable QTLs, with an average of 1.95 candidate genes per QTL. Among the 34 candidate genes annotated in the reference genome Chinese Spring (CS) RefSeq v1.1, the homologous genes of seven candidate genes, TraesCS1A02G-319900, TraesCS1B02G397300, TraesCS2D02G460800, TraesCS4A02G015600LC, TraesCS5B02G329200, TraesCS-6A02G000600 and TraesCS6A02G418600LC have been previously reported to play roles in aphid resistance. This suggests that these genes are strongly associated with EGA resistance in wheat. The candidate genes in this study should facilitate the cloning of EGA-resistant genes and genetic improvement in wheat breeding programs.
