#Unit 6. System Physiology – Plant
  1. SPY is an transcriptional factor induce transcription of GA-induced genes
  2. SPY is an active O-GlcNAc  transferase  that catalyzes the addition of a signal GlcNAc residue  via an O linkage to specific serine and/or threonine residues of target proteins
  3. SPY is an negative regulators of GAI and RGA
  4. SPY is an active N-GlcNAc  transferase

The recessive mutant allele that causes cystic fibrosis is much more frequent in Caucasians population than in other world populations. Some scientists believe heterozygotes must have had a survival advantage during plagues such as cholera that occasionally swept through this population. What concept does this illustrate?
