Induced pluripotent stem cell (iPSC) with the pluripotency of an embryonic stem cell. These genes were 

a. Sox2 and Oct4 (Oct3, Oct3/4, and Pou5f1) -which activated Nanog and other transcription factors that   established pluripotency and blocked differentiation

b. c-Myc which opened up chromatin and made the genes accessible to Sox2, Oct4, and Nanog

c. Klf4 -which prevents cell death

Examples of phenomena involved in this High Irradiance Response (HIR) include: 

• anthocyanin synthesis in seedlings and apple skins

• inhibition of hypocotyl elongation in mustard, lettuce and petunia

• plume hook opening in lettuce

• cotyledon enlargement in lettuce

• ethylene production in sorghum

When a genome contains a cluster of genes with related sequences, mispairing between nonallelic loci can cause unequal crossing over. This produces a deletion in one recombinant chromosome and a corresponding duplication in the other.
