“…Most cytoplasmic and nuclear proteins are degraded in a ubiquitin (Ub) and 26S proteasome-mediated manner (Delauré et al, 2008). The non-lysosomal intracellular protein degradation mediated by this pathway is essential for the regulation of various cellular processes, such as development, cell cycle, cell growth, and transcription (Jesenberger and Jentsch 2002).…”

“…Recently, evidence is heavily accumulating which suggests that the ubiquitin/proteasome pathway may control a range of cellular signaling processes in plants, such as those mediated by hormones, light and sucrose, as well as development and response to pathogens (Ellis et al, 2002;Smalle and Vierstara, 2004). The ubiquitin cascade is operated sequentially in a multi-step fashion by a multi-enzymatic system, consisting of ubiquitin-activating (E1), -conjugating (E2), and -ligating (E3) enzymes (Delauré et al, 2008;Glickman and Ciechanover, 2002). E3 ubiquitin ligases mediate the final transfer of ubiquitin to the target proteins, and therefore, they represent an important portion of the degradation process.…”

“…The E3 ubiquitin ligases can be classified in two major groups: those containing a HECT (for homology to E6-associated protein C-terminus) domain and those with a RING (really interesting new gene) or RING-like (called U-box) domain. The in silico analyses on the expression of all annotated E3 ubiqutin ligase components reveal that biotic stress induces up-regulation and down-regulation of up to 548 and 382 E3 ubiquitin ligase components, respectively (Delauré et al, 2008). E3 ubiquitin ligases and the related protein breakdown have been shown to play an important role in the signal transduction pathways leading to disease resistance (Delauré et al, 2008;Devoto et al, 2003;Dreher and Callis 2007).…”

E3 ubiquitin ligases are involved in plant defenses by controlled proteolysis in i) 'gene-for-gene' disease resistance, ii) early defense response reactions and iii) late induced defense responses (Delauré et al, 2008;Read Dreher andCallis, 2007, andDelauré et al, 2008 to get more detailed information).…”

Roles of Plant Proteases in Pathogen Defense

The genomes of plants contain more than 600 genes encoding a diverse set of proteases and the subunits of proteasomes. These proteases and proteasomes consist of plant proteolytic systems, which are involved in various cellular metabolic processes. Plant proteolytic systems have been shown to have diverse roles in defense responses, such as execution of the attack on the invading organisms, participation in signaling cascades, and perception of the invaders. In order to provide a framework for illustrating the importance of proteolytic systems in plant defense, characteristics of non-proteasome proteases and the 26S proteasome are summarized. The involvement of caspase-like proteases, saspases, apoplastic proteases, and the 26S proteasome in pathogen defense suggests that plant proteolytic systems are essential for defense and further clarity on the roles of plant proteases in defense is challenging but fundamentally important to understand plant-microbe interactions.

“…The ELISA technique is based on the ability of antibodies to recognize proteins, typically coat protein, from a specific virus of interest. The level of viral proteins present at any one time in a specific tissue is a dynamic relationship between protein synthesis versus protein degradation by the plant's defense system (Delaure et al, 2008). The RT-PCR assay utilizes viral RNAs in various tissues and converts them into cDNAs by reverse transcription (RT).…”

Comparison of ELISA and RT-PCR assays for the detection of Tomato spotted wilt virus in peanut

Diagnosis of Tomato spotted wilt virus (TSWV) in peanut can be accomplished by enzyme-linked immunosorbent assay (ELISA) or reverse transcription polymerase chain reaction (RT-PCR) but there has been no report of a direct comparison of the success of the two assays in evaluating infection rates of field-grown peanut. We collected peanut root samples from field-grown plants, 76 in 2006 and 48 in 2007, and tested these samples by both ELISA and RT-PCR assays for the presence of TSWV. Out of 124 samples, 50 (40.3%) and 57 (46.0%) were positive for TSWV by ELISA and RT-PCR respectively. In 13.7% of these samples, ELISA and RT-PCR differed in their results. However, Chi square analysis showed no significant difference between the results for these two assays. This result supports the conclusion that ELISA and RT-PCR are comparable for detecting TSWV infection rates in field-grown peanuts.

Anthracnose disease of sorghum is caused by Colletotrichum sublineola, a filamentous fungus. The genetic basis of resistance to anthracnose in sorghum is largely unclear, especially in Senegalese sorghum germplasm. In this study, 163 Senegalese sorghum accessions were evaluated for response to C. sublineola, and a genomewide association study (GWAS) was performed to identify genetic variation associated with response to C. sublineola using 193,727 single nucleotide polymorphisms (SNPs) throughout the genome. Germplasm diversity analysis showed low genetic diversity and slow linkage disequilibrium (LD) decay among the Senegalese accessions. Phenotypic analysis resulted in relatively low differences to C. sublineola among the tested population. Genome-wide association study did not identify any significant association based on a strict threshold for the number of SNPs available.However, individual analysis of the top eight SNPs associated with relative susceptibility and resistance identified candidate genes that have been shown to play important roles in plant stress tolerance in previous studies. This study identifies sorghum genes whose annotated properties have known roles in host defense and thus identify them as candidates for use in breeding for resistance to anthracnose.
