WebJul 8, 2015 · For over 100 years it has been known that a blue light photoreceptor regulates growth and development in plants under low-light conditions. These photoreceptors were termed cryptochomes (CRYs) because of their importance in cryptogamic plants and the cryptic aspects of their function and photochemistry ( 1, 2 ). WebThe power of genetics in A. thaliana allowed the identification of cry1 (cryptochrome 1), which was found by looking for seedlings which did not fully de-etiolate in blue light. The hy4/cry1 mutant was isolated in the first mutant screen for light-insensitive mutants in A. thaliana ( Kendrick and Kronenberg, (1994) ).
WebThe main quantity of interest is the activation yield of cryptochrome. This yield corresponds to the formation of the product FADH + Trp-324 dep. The yield depends on the strength and orientation of the magnetic field, described through (B 0, θ, ϕ) and is given by the expression. Φ(B0, θ, ϕ) = ∫ ∞ 0 kd Tr[ρ3(t)] dt. WebJun 21, 2011 · This is one of the ways in which the Earth’s magnetic field can affect living cells. It explains why the magnetic sense of animals like birds is tied to vision – after all, cryptochrome is found in the eye, and it’s converted into a radical pair by light. Several experiments in the past few decades have support Schulten and Ritz’s theory.
