“…In addition, the expression levels of C4H, C3H, 4CL, CCoAOMT and CAD, other crucial genes related to phenylpropanoid biosynthesis, were also up-regulated with Bacillomycin D-C16 treatment. Chlorogenic acid, caffeic acid and ferulic acid are three important phenolic substances and intermediates of the phenylpropanoid biosynthesis pathway [ 21 ]. Lignin, the product of phenolic acid-derived compounds, gives structural support and pathogen defense for the fruit [ 22 ].…”

Background Bacillomycin D-C16 can induce resistance in cherry tomato against pathogens; however, the underlying molecular mechanism is poorly understood. Here, the effect of Bacillomycin D-C16 on induction of disease resistance in cherry tomato was investigated using a transcriptomic analysis. Results Transcriptomic analysis revealed a series of obvious enrichment pathways. Bacillomycin D-C16 induced phenylpropanoid biosynthesis pathways and activated the synthesis of defense-related metabolites including phenolic acids and lignin. Moreover, Bacillomycin D-C16 triggered a defense response through both hormone signal transduction and plant-pathogen interactions pathways, and increased the transcription of several transcription factors (e.g., AP2/ERF, WRKY and MYB). These transcription factors might contribute to the further activated the expression of defense-related genes (PR1, PR10 and CHI) and stimulated the accumulation of H2O2. Conclusion Bacillomycin D-C16 can induce resistance in cherry tomato by activating the phenylpropanoid biosynthesis pathway, hormone signal transduction pathway and plant-pathogen interactions pathway, thus activating comprehensive defense reaction against pathogen invasion. These results provided a new insight into the bio-preservation of cherry tomato by the Bacillomycin D-C16.

Leaf spot is considered as a common disease of oil palm, caused primarily by Curvularia spp. fungi. This disease mainly affects the early stages of oil palm and if not adequately controlled can cause plant death. Among the methods available to control the disease, breeding resistant varieties is the most economically effective and promising strategy. A genome‐wide association study for leaf spot resistance was conducted on 210 individual tenera palms from seven different (origin) crosses. These palms were subsequently infected with Curvularia spp. pathogenic inoculum in a nursery trial located in an endemic area. The area under the disease progress curve was used as a phenotypic measure. In addition, a genotyping‐by‐sequencing (GBS) approach was used to obtain the genotyping data of each individual. We found two loci, at chromosome 2 and chromosome 13, that were significantly associated with leaf spot disease resistance. Six genetic variants at the two loci (five variants at chromosome 2 and one variant at chromosome 13) surpassed the threshold for genome‐wide significance (p < 106). These loci are linked with three widely known disease‐related genes, namely, resistance gene analogue 3 (RGA3), resistance gene analogue 4 (RGA4) and receptor‐like protein 9a (RLP9a). The loci identified here can be used for marker‐assisted selection when developing leaf spot disease‐resistant oil palm varieties.

When oil palm is exposed to, and infected by Ganoderma boninense, the initial defence system is launched in the roots to reduce the damage caused by the disease. The present work described the transcript and protein profiles in roots of 18 month-old oil palm seedlings that were exposed to the fungal pathogen for 12 months, following artificial inoculation at 6 month-old. Three different phenotypes were observed; control (uninoculated), asymptomatic, and symptomatic (inoculated). It was found that the transcripts from the ubiquitin-mediated proteolysis pathway were common in control and asymptomatic seedlings; while proteins involved in cellular processes, and protein and sugar metabolisms were higher in abundance in asymptomatic seedlings. The transcripts involved in carbon fixation, glycolysis/gluconeogenesis, and pyruvate metabolism together with proteins responsible for stress response were identified in symptomatic seedlings. By integrating these omics data, it was observed that symptomatic seedlings were moving towards generating and storing energy for a possible defence strategy, and at the same time emitting stress signals and responses. This was in contrast with asymptomatic seedlings where regular functions such as cellular processes and carbohydrate metabolisms were found to be active.
