Introduction
Holder of a PhD in agronomic sciences, Habilitated to lead research in physiology of stress, I am working at Ibn Tofail University, Morocco, for more than 28 years. My research work is related to understand the physiology of cultivated and spontaneous plants, particularly mineral nutrition, as adaptive response to diseases and environmental conditions. In parallel, I was involved in several international research programs for instance, as a partner in an INCO, CRP, FRAB, PRAD, ... projects.

Psorosis is a globally devastating disease of
citrus caused by an infectious filamentous ophiovirus, Citrus
psorosis virus (CPsV), which causes annual losses of about
5 % and a progressive decline of trees by affecting the
conductive tissues. The disease can be harboured asymptomatically
in many citrus species. In the field, the most
characteristic...
Broomrape represents one of the most intractable parasitic weed problems for faba bean in
Mediterranean region. It causes enormous yield losses, and few control measures are effective. Recently, a novel strategy based on parasite-induced expression of a selective sarcotoxin IA polypeptide in transgenic tobacco was used to control broomrape. Generat...
