BIO341H5 Lecture Notes - Lecture 19: Bradykinin Receptor B2, Ploidy, Dna-Binding Domain
Document Summary
Mat, mating type locus that controls, mat a and mat alpha. Recognition system pheromones, short peptide proteins controlled by mat. Haploid to diploid state, that allow for meiosis. Diploid cell but no nuclear fusion; propagated indefinitely dikaryon. Any time they are the same, incompatible. A2 + - + + (inbreeding) siblings from same parents 50%, from different parents, ~100% A1b1 a2b1 a1b2 a2b2 a3b3 a2b3 a3b4 a4b4. A1b1 - - - + + + + + A2b1 - - + - + + + + A1b2 - + - - + + + + A2b2 + - - - + + + + After fusion, compatible mating, solid nucleus migrate through mycelium. Start to pair with one another, controlled by a gene, clamps that are formed, division, solid nuclei have divided, clamp connection b controls the fusion, septal destruction that has to happen for fusion. Different mating types at a and at b.
