Any process that increases the frequency, rate or extent of gene expression. Gene expression is the process in which a gene's coding sequence is converted into a mature gene product or products (proteins or RNA). This includes the production of an RNA transcript as well as any processing to produce a mature RNA product or an mRNA or circRNA (for protein-coding genes) and the translation of that mRNA or circRNA into protein. Protein maturation is included when required to form an active form of a product from an inactive precursor form.

The chemical reactions and pathways resulting in the formation of polyketides, any of a diverse group of natural products synthesized via linear poly-beta-ketones, which are themselves formed by repetitive head-to-tail addition of acetyl (or substituted acetyl) units indirectly derived from acetate (or a substituted acetate) by a mechanism similar to that for fatty acid biosynthesis but without the intermediate reductive steps.

The chemical reactions and pathways resulting in the formation of 1-(3,5-dichloro-2,6-dihydroxy-4-methoxyphenyl)hexan-1-one, also known as DIF-1, differentiation-inducing factor-1. DIF-1 is a secreted chlorinated molecule that controls cell fate during development of Dictyostelium cells.

The process in which a relatively unspecialized cell acquires specialized features of a sorocarp stalk cell, any of the cellulose-covered cells that form the stalk of a sorocarp. An example of this process is found in Dictyostelium discoideum.

The process in which the sorocarp is generated and organized. An example of this process is found in Dictyostelium discoideum.

A form of programmed cell death that is accompanied by the formation of autophagosomes. Autophagic cell death is characterized by lack of chromatin condensation and massive vacuolization of the cytoplasm, with little or no uptake by phagocytic cells.
