In the light, cry1 is activated directly by blue light and indirectly by blue lightinduced phosphorylation. Activated cry1 forms a complex with COP1 and SPA1 via the C-terminal domain, preventing them from degrading protein targets such as HY5

Like ABA, strigolactones are derived from carotenoid precursors in plastids in a pathway that is conserved up to synthesis of the intermediate carlactone, beyond which strigolactone biosynthesis diverges in a species- specific manner

There are 3 cellular ways to treat mutations on DNA

Repair- Most common

Reversal- Most expensive and rare

Bypass – Last resort and carry mutation without correction

#Unit 11. Evolution and Behavior

Sexual dimorphism can evolve when selection favors the expression of a trait to be different in males and females. 

This situation is called sexually antagonistic selection, because an increase in the trait’s expression benefits one sex but harms the other.
