The comparison of the results of phy CD, phy AD, and phy ACD and how it relates to the necessity of phyC and phyA genes in determining leaf area in Arabidopsis. Given: It has been given in the experiment results that phy CD, phy AD, and phy ACD show similar leaf area in Arabidopsis. Introduction: Leaf area in Arabidopsis is determined by a number of phytochrome genes. These genes either function in synergy or can be overlapping in their function. Phytochromes are special receptors which detect light and get transformed into an active state. This active state then induces a signaling cascade that affects the development of plants such as determining the leaf area.

In Arabidopsis, it is well-known that a pulse of full-spectrum light during the night (in an otherwise long night) will induce flowering. This suggests that plants measure the length of night, and not the length of day. If the pulse of light during the night was blue light instead of full spectrum light, what would be the flowering time response of a plant with a knockout in cry2 (relative to wild type in the same conditions)? Explain.
