“…5). An increase in OPDA concentration in response to wounding has been documented before [60][61][62][63], while JA levels were not necessarily altered [64,65]. On the other hand, increased expression of OPR related JA biosynthesis genes in SB could be explained by our previous observations that greenbugs begin to feed on the S genotype soon after infestation [41], triggering basal defense responses.…”

“…COI1 encodes a 66-kDa protein with amino-terminal F-box motif and a leucine-rich repeats (LRR) domain close to the carboxy-terminal end [47]. COI1 is required for plant response to jasmonic acids (JAs), which regulate root growth, pollen fertility, wound healing, and defense against insects and pathogens [48,49]. The coi1 mutant fails to express the defense-related gene plant defensin 1.2 (PDF1.2) and is susceptible to insect herbivory and to pathogens [50,51].…”

Ubiquitination-mediated protein degradation and modification: an emerging theme in plant-microbe interactions

Post-translational modification is central to protein stability and to the modulation of protein activity. Various types of protein modification, such as phosphorylation, methylation, acetylation, myristoylation, glycosylation, and ubiquitination, have been reported. Among them, ubiquitination distinguishes itself from others in that most of the ubiquitinated proteins are targeted to the 26S proteasome for degradation. The ubiquitin/26S proteasome system constitutes the major protein degradation pathway in the cell. In recent years, the importance of the ubiquitination machinery in the control of numerous eukaryotic cellular functions has been increasingly appreciated. Increasing number of E3 ubiquitin ligases and their substrates, including a variety of essential cellular regulators have been identified. Studies in the past several years have revealed that the ubiquitination system is important for a broad range of plant developmental processes and responses to abiotic and biotic stresses. This review discusses recent advances in the functional analysis of ubiquitination-associated proteins from plants and pathogens that play important roles in plant-microbe interactions.

“…JA-and ethylene-mediated signaling pathways are distinct from the classic SA-mediated SAR pathways [15]. For example, induced systemic resistance (ISR), which is triggered by nonpathogenic root-colonizing bacteria, is JA and ethylene dependent [16,17] and is independent of SA and PR-gene activation [18,19].…”

OsWRKY03, a rice transcriptional activator that functions in defense signaling pathway upstream of OsNPR1

WRKY family proteins are a class of plant specific transcription factors that involve in many stress response pathways. It has been shown that one Arabidopsis WRKY protein, AtWRKY29/22, is activated by MAP kinase signaling cascade and confers resistance to both bacterial and fungal pathogens. However, little is known about the biological roles of WRKY proteins in rice. In this study, we investigated the expression patterns of rice AtWRKY29/22 homolog, OsWRKY03, under different conditions, and also its possible role involved in plant defense. Our results showed that OsWRKY03 was up-regulated by several defense signaling molecules or different treatments. Further analysis revealed that the expression of OsWRKY03 was light dependent. Transcriptional activation activity of OsWRKY03 was also demonstrated by yeast functional assay. Transient expression of OsWRKY03-GFP fusion protein in onion epidermis cells showed that OsWRKY03 was a nuclear localized protein. OsNPR1 as well as several other pathogenesis-related genes, such as OsPR1b, phenylalanine ammonia-lyase (ZB8) and peroxidase (POX22.3), were induced in OsWRKY03-overexpressing transgenic plants. These results indicated that OsWRKY03 is located upstream of OsNPR1 as a transcriptional activator in salicylic acid (SA)-dependent or jasmonic acid (JA)-dependent defense signaling cascades.
