It seemed like a “coming-of-age” young field that has gradually coalesced from range of distinct areas and an opportunity make statement about importance interactions ecologically, agriculturally beyond. Looking back, did not realise actually jumping “into deep end,” without having l...

The ability of plants to fulfill nutritional needs by parasitizing neighboring plants has originated several times in angiosperm evolution. Molecular tools are now being exploited to investigate the evolutionary origins of plant parasitism and to dissect the genetic mechanisms governing parasitic plant-host plant interactions. Investigating the nature of signal exchanges between parasitic plant...
