#Unit 5. Developmental Biology
The Dictyostelia social
amoebas are found in a wide range of soil habitats. They can come together to
form a fruiting structure, in which a proportion of cells are sacrificed to
build the stalk and the remainder differentiate into resilient dormant spores.
This multicellular life cycle is common to all Dictyostelids. It consists
of an interconnected programme of cell movement and cell differentiation, and
has been intensively studied in the model organism D. discoideum. Few mutants
(Column A) and phenotypes (Column B) are listed in the table given below.
