It’s far from certain that peat bogs can continue absorbing carbon dioxide at current rates
A common claim is that rising carbon dioxide is actually good for plants. Research from Sweden shows that reality is more complicated.

Waking up to respiration: leaf respiration in the light alters our interpretation of ecosystem carbon fluxes
In plants, respiration is usually inhibited in the light compared to the dark. Measuring respiration in the light is particularly difficult, because photosynthesis and photorespiration are occurring as well...

Photosynthetic plasticity and survival across the Triassic-Jurassic boundary
Why did Gingko almost disappear during the Triassic–Jurassic mass extinction when ferns did so well? The answer has relevance for future atmospheric changes.

Where in the epidermis would you find chloroplasts?
There are several answers to this question. I expect all of you to say guard cells. Those of you who’ve read the previous item about chlorophagy might also be tempted to say plant vacuoles – presumably of guard cells...

Temperature responses of photosynthesis under elevated CO2
Plants growing under elevated atmospheric CO2 concentrations often have reduced stomatal conductance and subsequently increased leaf temperature. Šigut et al. find that this is indeed the case for broadleaved Fagus...
Peroxisomes and regulation of ROS/RNS signalling (Review)
Sandalio and Romero-Puertas review the metabolism of reactive oxygen and nitrogen species (ROS and RNS) in peroxisomes and their contribution to the regulation of plant development and acclimation to stress conditions.
An explosive mix: C4, C3, C2 and CCM
How many more variants exist amongst the 325,000 species of flowering plants (let alone all the algae and other members of the plant kingdom)?
Relocation, relocation, relocation…
A study shows cold-induced organelle relocation in the liverwort Marchantia polymorpha, not only of chloroplasts, but nuclei and peroxisomes, too.
