Citrus bacterial canker (CBC) caused by Xanthomonas citri subsp. citri (Xcc), is the most devastating of the citrus diseases worldwide. During our study, we found that Essential oils (EOs) of some citrus cultivars are effective on Xcc. Therefore, it prompted us to determine the plant metabolites responsible for the antibacterial properties. We obtained EOs from some locally cultivated citrus by...

Callus tissues induced from shoots of species in the orange subfamily (Aurantioideae) were grafted in vitro to evaluate the correlation between reaction at the callus graft interface and taxonomic relationship. The graft interface between two pieces of callus from species that are taxonomically close was not distinguishable by anatomical observations. On the other hand, in the combinations of l...

A broad range of plant selections across the orange subfamily Aurantioideae were screened in solution and soil culture for their tolerance to low iron (Fe) stress. Young seedlings grown in soil were transferred to tubs of +Fe nutrient solution, which was later replaced after a brief period with a –Fe solution. Over several trials, ’20 white root tips were harvested periodically from the plants ...
