The Rim101p/PacC pathway and alkaline pH regulate pattern formation in yeast colonies.
Multicellular organisms utilize cell-to-cell signals to build patterns of cell types within embryos, but the ability of fungi to form organized communities has been largely unexplored. Here we report that colonies of the yeast Saccharomyces cerevisiae formed sharply divided layers of sporulating and nonsporulating cells. Sporulation initiated in the colony's interior, and this region expanded u...
متن کاملCoupled feedback loops form dynamic motifs of cellular networks.
Cellular networks are composed of complicated interconnections among components, and some subnetworks of particular functioning are often identified as network motifs. Among such network motifs, feedback loops are thought to play important dynamical roles. Intriguingly, such feedback loops are very often found as a coupled structure in cellular circuits. Therefore, we integrated all the scatter...

MATERIALS Taq DNA polymerase Marker DNA As a reference, use single-stranded DNA from the original bacteriophage M13 recombinant. MgCl2 (25 mM) Oligonucleotide primers The oligonucleotides should be 20-24 nucleotides in length, specific for the target DNA sequences, free of potential secondary structures, and contain no less than 10 and no more than 15 G and C residues. Yeast colony PCR buffer, ...
متن کاملHow different types of pattern formation mechanisms affect the evolution of form and development.
Here we investigate how development and evolution can affect each other by exploring what kind of phenotypic variation is produced by different types of developmental mechanisms. A limited number of developmental mechanisms are capable of pattern formation in development. Two main types have been identified. In morphodynamic mechanisms, induction events and morphogenetic processes, such as simp...
