Current Status and Complexity of Three Species in Pepper Plants in Lowlands and Highlands in Java Island, Indonesia.

Three primary species from the genus, (PepYLCIV), (TYLCKaV), and (ToLCNDV), are suspected of spreading throughout pepper production centers, and plants are infected by a single species or a combination of two or three species. This study was conducted to provide complete information about the symptoms, incidence and severity, whitefly biotypes, as well as the dominance status of the three species in pepper-producing areas in Java. A DNA analysis was carried out on leaf samples to identify species and biotypes of collected from 18 areas (16 districts) in lowlands (<400 m asl) and highlands (>700 m asl).

Rubber Genotypes with Contrasting Drought Factor Index Revealed Different Mechanisms for Drought Resistance in .

It is predicted that drought will be more frequent and sustained in the future, which may affect the decline of rubber tree production. Therefore, it is critical to research some of the variables related to the drought-resistance mechanism of the rubber tree. As a result, it can be used to guide the selection of new rubber drought-resistance clones.

Metabolomic Response of Tomatoes ( L.) against Bacterial Wilt () Using H-NMR Spectroscopy.

is the pathogen responsible for wilting, yield losses, and death in tomato plants. The use of resistant cultivars has been proven as the most appropriate solution to controlling this pathogen. Therefore, further study of host-plant resistance mechanisms in tomatoes is urgently needed.

Metabolomics Approach for the Analysis of Resistance of Four Tomato Genotypes ( L.) to Root-Knot Nematodes ().

Metabolomics allows the identification of biochemical markers that have important roles in plant resistance to pests and diseases by which breeders can select plants based on differences in these compounds. This study examines the range of compounds associated with plant defense against nematodes. Resistant tomato genotypes, GM2 and F1 (GM2 × Hawai 7996), and susceptible genotypes, Gondol Putih and Gondol Hijau, were used in this study.
