New paper: Pectin modifications promote haustoria development in the parasitic plant Phtheirospermum japonicum

Plant Physiology Martina Leso, Anna Kokla, Ming Feng & Charles W Melnyk   The formation of the haustorium is common to all parasitic plants and requires a dedicated process of growth, attachment and tissue invasion. Such a process presumably involves cell wall modifications to allow cell division, cell expansion and the digestion of host […]

Nitrogen represses haustoria formation through abscisic acid in the parasitic plant Phtheirospermum japonicum

The availability of nutrients in the environment can have dramatic effects on plant parasitism, for instance, Striga infestations are reduced in nutrient rich soils. The molecular basis for this phenomenon is not well known so we decided to investigate this further with the Orobanchaceae family member Phtheirospermum japonicum. It’s a facultative parasite which infects Arabidopsis […]
