Watch Seeds In 3DEmbryonic photosynthesis leads to the production of seed-internal oxygen that is important for seed development and quality. In order to visualise seed-internal structures that could serve for oxygen storage conventional microscopic methods could not be used because they require the seed to be cut thus leading to air escape. By using holotomography at the ESRF, researchers could get the full picture of an arabidopsis seed without any structural........Go to the My-media-blog (Added on 9/15/2006 1:47:38 PM)
