New clues could help scientists harness the power of photosynthesis
Model of the newly-identified clorophyll f synthase enzyme that converts chlorophyll a into chlorophyll f. The model is based on the known structure of the Photosystem II reaction center -- a core unit of the machinery of photosynthesis to which the enzyme is related. The bright green molecules near the bottom of the structure represent chlorophyll a molecules that would be modified in light to produce chlorophyll f. Credit: Bryant lab, Penn State University
Discovered: How to unlock inaccessible genes
This image shows the binding profile of chromatin remodelers on 12,000 distinct genes. The researchers used bioinformatics tools to visualize a great number of genes, here aligned by their promoters and arranged according to their nucleosome distribution.
