“…Among them, m.172302 (chitinase) and m.144144 (hevamine-A precursor), two basic vacuolar chitinases with lysozyme activity (Subroto et al 1996), were induced by ethephon both in high-and low-sugar genotypes. While m.71264 (chitinase) and m.44939 (chn1, acidic endochitinase-like), which also play an important role on disease defense reaction (Kurilla et al 2019), were induced by ethylene only in lowsugar genotype. The results suggest that different chitinases elicit diverse functions in sugarcane.…”

“…Some cis-acting regulatory elements are involved in stress responses, such as hormones, dehydration, and cold responses (Liu et al, 2017;Osakabe et al, 2014;Pieterse & Van Loon, 2004;Sakuma et al, 2002). Some cis-acting regulatory elements are known to mediate plant immunity (Kurilla et al, 2019;Shan et al, 2016;Yu et al, 2019). The predicted cis-acting regulatory elements in the promoter regions of TaUBPs are provided in Table S4.…”

Ubiquitination is essential for plant growth and development. Deubiquitination cooperates with ubiquitination to regulate the ubiquitination levels of target proteins. The ubiquitin-specific protease (UBP) family is the largest group of deubiquitinases (DUBs), which perform extensive and significant roles in eukaryotic organisms. However, the UBP genes in wheat (TaUBPs) are not identified, and the functions of TaUBPs are unknown. The present study identified 97 UBP genes in the whole genome of T. aestivum. These genes were divided into 15 groups and non-randomly distributed on chromosomes of T. aestivum. Analyses of evolutionary patterns revealed that TaUBPs mainly underwent purification selection. The studies of cis-acting regulatory elements indicated that they might be involved in response to hormones. Quantitative real-time PCR (qRT-PCR) results showed that TaUBPs were differentially expressed in different tissues. Besides, several TaUBPs were significantly up-regulated when plants were treated with salicylic acid (SA), implying that these DUBs may play a role in abiotic stress responses in plants and few TaUBPs displayed differential expression after viral infection. Furthermore, TaUBP1A.1 (TraesCS1A02G432600.1) silenced by virus-induced gene silencing (VIGS) facilitates Chinese wheat mosaic virus (CWMV) infection in wheat, indicating that TaUBP1A.1 may be involved in a defense mechanism against viruses. This study comprehensively analyzed the UBP gene family in wheat and provided a basis for further research of TaUBPs functions in wheat plant response to viral infection.

“…For example, VdMYB1 binds to the MBS in the VdSTS2 gene promoter, thus activating VdSTS2 transcription and positively regulating defense responses [36]. Machi3-1 and TaRIM1 also bind MBS cis-acting elements to increase host resistance [37,38].…”

Background: Nicotiana benthamiana is widely used as a model plant to study plant-pathogen interactions. Fasciclin-like arabinogalactan proteins (FLAs), a subclass of arabinogalactan proteins (AGPs), participate in mediating plant growth, development and response to abiotic stress. However, the members of FLAs in N. benthamiana and their response to plant pathogens are unknown. Results: 38 NbFLAs were identified from a genome-wide study. NbFLAs could be divided into four subclasses, and their gene structure and motif composition were conserved in each subclass. NbFLAs may be regulated by cis-acting elements such as STRE and MBS, and may be the targets of transcription factors like C2H2. Quantitative real time polymerase chain reaction (RT-qPCR) results showed that selected NbFLAs were differentially expressed in different tissues. All of the selected NbFLAs were significantly downregulated following infection by turnip mosaic virus (TuMV) and most of them also by Pseudomonas syringae pv tomato strain DC3000 (Pst DC3000), suggesting possible roles in response to pathogenic infection. Conclusions: This study systematically identified FLAs in N. benthamiana, and indicates their potential roles in response to biotic stress. The identification of NbFLAs will facilitate further studies of their role in plant immunity in N. benthamiana.

Nectar- and stigma exudate-specific expression of an acidic chitinase could partially protect certain apple cultivars against fire blight disease

Abstract: Main conclusion Certain apple cultivars accumulate to high levels in their nectar and stigma exudate an acidic chitinase III protein that can protect against pathogens including fire blight disease causing Erwinia amylovora.
