Aims: Our goal was to understand the symbiotic behaviour of a Mesorhizobium strain expressing an exogenous 1‐aminocyclopropane‐1‐carboxylate (ACC) deaminase, which was used as an inoculant of chickpea (Cicer arietinum) plants growing in soil. Methods and Results: Mesorhizobium ciceri LMS‐1 (pRKACC) was tested for its plant growth promotion abilities on two chickpea cultivars (ELMO and CHK3226) growing in nonsterilized soil that displayed biotic and abiotic constraints to plant growth. When compared to its wild‐type form, the M. ciceri LMS‐1 (pRKACC) strain showed an increased nodulation performance of c. 125 and 180% and increased nodule weight of c. 45 and 147% in chickpea cultivars ELMO and CHK3226, respectively. Mesorhizobium ciceri LMS‐1 (pRKACC) was also able to augment the total biomass of both chickpea plant cultivars by c. 45% and to reduce chickpea root rot disease susceptibility. Conclusions: The results obtained indicate that the production of ACC deaminase under free living conditions by Mesorhizobium strains increases the nodulation, plant growth abilities and biocontrol potential of these strains. Significance and Impact of the Study: This is the first study regarding the use of a transformed rhizobial strain expressing an exogenous ACC deaminase in different plant cultivars growing in soil. Hence, obtaining Mesorhizobium strains with high ACC deaminase activity is a matter of extreme importance for the development of inoculants for field applications.

“…This ET dichotomy has also been observed in tomato plants treated with the ET precursor, 1-aminocyclo-propane-1-carboxylate (ACC), at the time of inoculation to produce an initial transient burst of ET, and then blocked the ET production by adding the ethylene biosynthesis inhibitor aminoethoxyvinylglycine (AVG). By this consecutive treatment with ACC and AVG, symptom severity caused by V. ahlia is reduced further than each treatment alone [ 17 ]. Besides its involvement in resistance, ET controls symptom development in tomato [ 37 ].…”

“…Ethylene has been involved in both resistance and susceptibility to Verticillium [ 17 ]. Robison et al [ 17 ] showed that post-infection ethylene enhances Verticillium wilt development in tomato, whereas its presence at the time of infection inhibits disease development. In pepper, expression of a basic PR-1 is positively regulated by ET [ 18 ].…”

The non-pathogenic Fusarium oxysporum Fo47 is able to protect Capsicum annuum (pepper) but not in Solanum lycopersicum (tomato) against the pathogen Verticillium dahliae. Transcriptomics of the plant during the interaction with Fo47 shows the induction of distinct set of genes in pepper and tomato. The number of differentially expressed (DE) genes in pepper (231 DE genes) is greater than the number of DE genes in tomato (39 DE genes) at 2 days after the treatment with Fo47. Ethylene related genes were present among the DE genes in both plants, and the up-regulation of ethylene biosynthetic genes was observed to be triggered during the interaction of both plants with Fo47. The treatment with MCP (1-Methylcyclopropene, an ethylene-competitive inhibitor) reduced the Fo47 protection in pepper against Verticillium dahliae. Intriguingly, Fo47 was able to protect the ethylene-insensitive tomato mutant Never-ripe (Nr) against Verticillium dahliae, but not the tomato wilt type cv Pearson. Overall, ethylene is shown to be an important player in the response to Fo47, but its role depends on the host species.

“…The process of plant response to pathogenic bacteria is regulated by multiple signals, in which plant hormones play a key role (Katagiri and Tsuda 2010). Previous studies suggested that ET had a multiple effect on the interaction between plants and Verticillium wilt, with several genes activated by ET in response to Verticillium wilt, including ethylene responsive factor (ERF6), ERF1 and GbERF1-like (Robison et al 2001;Yang et al 2015;Guo et al 2016). These transcription factors regulated the expression of downstream resistance proteins and increased the plant disease resistance.…”

Isolation and characterization of the GbVIP1 gene and response to Verticillium wilt in cotton and tobacco

Background: Verticillium wilt is a serious soil-borne vascular disease that causes major losses to upland cotton (Gossypium hirutum L.) worldwidely every year. The protein VIP1 (VirE2 interaction protein 1), a bZIP transcription factor, is involved in plant response to many stress conditions, especially pathogenic bacteria. However, its roles in cotton response to Verticillium wilt are poorly understood. Results: The GbVIP1 gene was cloned from resistant sea-island cotton (G. barbadense) cv. Hai 7124. Expression of GbVIP1 was up-regulated by inoculation with Verticillium dahliae and exogenous treatment with ethylene. Results of virus-induced gene silencing suggested that silencing of GbVIP1 weakened cotton resistance to Verticillium wilt. The heterologous expression of GbVIP1 in tobacco showed enhanced resistance to Verticillium wilt. The PR1, PR1-like and HSP70 genes were up-regulated in GbVIP1 transgenic tobacco after Verticillium wilt infection. Conclusion: Our results suggested that GbVIP1 increased plant resistance to Verticillium wilt through up-regulating expressions of PR1, PR1-like, and HSP70. These results provide new approaches to improving resistance to Verticillium wilt in upland cotton and also have great potential for disease-resistance breeding of cotton.
