These species are present in coasts of the sea and brackish intertidal mud flats, lagoons and swamps, mangroves, salt marshes and sandy or muddy coasts of West Africa, the Western Atlantic, the Eastern Pacific, the Indo-Pacific and the...

To study the role of two genes sea4 and pca1 we constructed the knockout of both the genes. Metacaspases are the distant relatives of animal caspases found in plants, protozoa,and fungi. These metacaspases are also involved in regulating the development and environmentally induced programmed cell death. It has been approximately 10 years since metacaspases were discovered. During this time the pendulum has shifted from naive hopes that metacaspases are responsible for cell death events and associated caspase like activities in plants and other non metazoans to well grounded view that...
