The projects of 21 Biosciences Area scientists and engineers received funding through the FY24 Laboratory Directed Research and Development (LDRD) program.
Photosynthesis, Like a Moss
Using cryo-electron microscopy (cryo-EM), which allows an unprecedented level of resolution, Biosciences researchers compared the structure of photosystem I in the moss Physcomitrella patens with its structure in the small flowering land plant Arabidopsis thaliana, and in the green alga Chlamydomonas reinhardtii. Because moss evolved after algae but before vascular land plants, such comparisons can shed light on how plants evolved to move from the ocean to land.
