The picture above shows a higher magnification image of phyB seedlings growing in white light at the end of the growth phase of the time line during the spaceflight experiment. The distance between grid lines on the membranes is 3 mm, and the number (29) on the membrane refers to the specific seedling cassette. B2 on the image indicates the EC number.
