The impact of genetically modified canola (Brassica napus) on biodiversity has been examined since its initial stage of commercialization. Various research groups have extensively investigated crossability and introgression among species of Brassicaceae. B. rapa and B. juncea are ranked first and second as the recipients of cross-pollination and introgression from B. napus, respectively. Crossa...

Few studies have documented the response of gravitropically curved organs to a withdrawal of a constant gravitational stimulus. The effects of stimulus withdrawal on gravitropic curvature were studied by following individual roots of cress (Lepidium sativum L.) through reorientation and clinostat rotation. Roots turned to the horizontal curved down 62 degrees and 88 degrees after 1 and 5 h, res...

The occurrence of Alyssum desertorum, a species belonging to A. sect. Alyssum, is reported for the fi rst time in Italy. It was found in Abruzzo (central Italy) in the territory of National Park of Gran Sasso and Laga mountains and surrounding areas. Morphological similarities with the other taxa recorded in Italy belonging to A. sect. Alyssum are briefl y discussed. Information about the typif...

The circadian clock serves to coordinate metabolism and physiology with the diurnal cycles derived from daily rotation of earth. In Brassicaceae, rhythms contribute temporal variation in diverse phytochemicals and, hence, both resistance biotic stress edible crop health value. Understanding specialized metabolites present Brassica crops can improve selection future breeding strategies. this rev...
