“…Sulfur enhances defenses against plant disease through the formation of sulfur-containing defense compounds (SDCs)1113, and an increased sulfur supply increases the disease resistance of plants to pathogens7161718. Interestingly, the expression levels of genes related to sulfate uptake (high-affinity sulfate transporter) and assimilation and the formation of SDCs were all up-regulated in tomatoes grown with potato onion plants (Table 1), thus suggesting that sulfur-enhanced defense might play an important role in the enhanced resistance of tomatoes to V. dahliae, as described by Rausch and Wachter11.…”

“…Because the sulfur supply contributes to the disease resistance of plants78, the management of sulfur nutrition in the soil will be beneficial for plant defenses against pathogens. Several studies have demonstrated that the interactions between plants species may improve phosphorus and iron nutrition in plant rhizospheres through root exudates in intercropping systems1927.…”

“…Several management strategies have been developed for controlling this disease, such as cultivating the cultivars with Ve gene1, inducing plant resistance by using beneficial bacteria23, intercropping456, and enhancing plant defense against V. dahliae by using sulfur78. These strategies would lower production costs and reduce environmental pollution.…”

“…An increased sulfur supply increases the disease resistance of plants to pathogens and limits the spread of pathogens in plants, hence alleviating disease incidence and severity, whereas sulfur deficiency increases the susceptibility of plants to pathogens7161718. Thus, determining whether tomato/potato onion companion cropping may increase the availability of sulfur in the soil would be valuable for controlling tomato verticillium wilt.…”

Companion cropping with potato onions (Allium cepa var. agrogatum Don.) can enhance the disease resistance of tomato plants (Solanum lycopersicum) to Verticillium dahliae infection by increasing the expressions of genes related to disease resistance. However, it is not clear how tomato plants physiologically respond to V. dahliae infection and what roles sulfur plays in the disease-resistance. Pot experiments were performed to examine changes in the physiology and sulfur metabolism of tomato roots infected by V. dahliae under the companion cropping (tomato/potato onion). The results showed that the companion cropping increased the content of total phenol, lignin and glutathione and increased the activities of peroxidase, polyphenol oxidase and phenylalanine ammonia lyase in the roots of tomato plants. RNA-seq analysis showed that the expressions of genes involved in sulfur uptake and assimilation, and the formation of sulfur-containing defense compounds (SDCs) were up-regulated in the V. dahlia-infected tomatoes in the companion cropping. In addition, the interactions among tomato, potato onion and V. dahliae induced the expression of the high- affinity sulfate transporter gene in the tomato roots. These results suggest that sulfur may play important roles in tomato disease resistance against V. dahliae.

“…Gbvdr5 may be essential in debating with V. dahliae. In addition, a sulfur-responsive element SURECOREATSULTR11 was found in the promoter, and sulfur can enhance plant resistance to V. dahliae (Bollig et al 2013). It was here assumed that the sulfur-mediated enhanced resistance may also act through Gbvdr5.…”

A Cotton Gbvdr5 Gene Encoding a Leucine-Rich-Repeat Receptor-Like Protein Confers Resistance to Verticillium dahliae in Transgenic Arabidopsis and Upland Cotton

Leucine-rich-repeat receptor-like proteins (eLRRRLPs) play significant roles in plant defense against pathogens and in plant development. Several eLRR-RLP genes such as Ve1, Gbve, and Gbve1 have been reported to confer resistance to Verticillium dahliae. Gbvdr5, a newly discovered RLP gene from V. dahliae-resistant island cotton cultivar H7124, has a short tail as Ve1. There is a cytosine deletion in Gbvdr5 homologous genes at nucleotide position 2765, which is downstream from the initiation codon in all susceptible upland cotton cultivars analyzed. This deletion was found to cause premature termination of the protein, creating a 937 aa product, but the Gbvdr5 protein had the full 1,077 aa. Transient expression analyses indicated that Gbvdr5 is localized on the plasma membrane. Quantitative polymerase chain reaction analysis revealed that the Gbvdr5 gene was activated by SA, MeJA, ABA, and ETH, and it was induced by V. dahliae isolates V991 and DF-CQ-2 in H7124, whereas was unchanged or repressed in susceptible upland cotton Simian 3. Gbvdr5-promoter-driven GUS activity was found mostly in the root tips and stem growing points of transgenic Arabidopsis. Silencing of Gbvdr5 in Verticillium-wilt-resistant cotton H7124 compromised cotton resistance to V. dahliae isolates V991 and BP2. The resistance was verified by transforming the Gbvdr5 gene into Arabidopsis and upland cotton through Agrobacterium-mediated transformation. Overexpression of the Gbvdr5 gene endowed transgenic Arabidopsis with resistance to defoliating isolate V991 and non-defoliating isolate BP2, but it had no effect on either DF-CQ-2 or JR2 of V. dahliae. The transformed cotton also had confirmed resistance to V991 and BP2. More callose deposition, more expression of the defense-related genes PR1 and PR5, and HR-mimic cell death were observed in the transgenic Arabidopsis when inoculated with V. dahliae. This demonstrated that Verticillium-plant interactions may involve some specific ways of recognizing V. dahliae and Gbvdr5 may be a suitable candidate gene for breeding Verticillium-wilt-resistant cotton lines.
