Scientists have pinpointed the location of an essential enzyme in plant cells involved in photosynthesis, according to a study published today in
eLife.
The findings overturn conventional thinking about where the enzyme resides in plant cells and suggest a probable role in regulating energy processes as plants adapt from dark to light conditions.
During photosynthesis, plants convert carbon into energy stores through electron transport , involving an enzyme called ferredoxin:NADP(H) oxidoreductase, or FNR.
Plants can switch rapidly between two types of electron transport - linear electron flow (LEF) and cyclic electron flow (CEF) in response to environmental conditions. The transfer of FNR between membrane structures in the chloroplast, where photosynthesis takes place, has been linked to this switch.
Deforestation may cause an initial increase in malaria infections across Southeast Asia before leading to later decreases, a study published today in eLife suggests.
Odors evoke powerful memories, an experience enshrined in literature by Marcel Proust and his beloved madeleine. A new paper is the first to identify a neural basis for how the brain enables odors to so powerfully elicit those memories. The paper shows unique connectivity between the hippocampus the seat of memory in the brain and olfactory areas in humans. It s like a superhighway from smell to the hippocampus.
