The specific objectives of the research are the following:
- study the effectiveness of nano-chitosan against Phytophthora capsici on four chili pepper cultivars by knowing the resistance level of each cultivar, phenotypically;
- determine the gene expression activities on four chili pepper cultivars through the whole transcriptomic analysis; and
- decipher the complex molecular processes of plant-pathogen interaction in chili using transcriptomic datasets.
The project was conducted at Bandung and Purwakarta, West Java, Indonesia. The Plant Pathology Laboratory and Green House research facilities from EastWest Seed Indonesia Company was used in Purwakarta, while the genetics and molecular biology laboratory in the School of Life Science and Technology (SITH), Institut Teknologi Bandung, was utilized in Bandung. Figure 1 shows the primary production of chili pepper in West Java. The research focused on four chili pepper cultivars that are commonly used by farmers and preferred by the market. The four cultivars represent the variation of resistance level against Phytophthora capsici (EWINDO n.d.).
