The secret to conserving an endangered orchid is in the soil
A study of orchids shows the secret to conservation isn’t in the plants you can see, but the fungi you can’t.

Evolution and function of Scots pine aminopropyltransferases
Vuosku and colleagues find an evolutionarily old gymnosperm, Scots pine, has a bifunctional SPDS able to produce both Spd and Spm, while angiosperms seem to depend on separate enzymes in Spd and Spm biosynthesis.

Xylogenesis and IADF formation in Mediterranean softwoods and hardwoods
How do tree growth rings, species and climate interact? A study into xylogenesis in Annals of Botany takes a closer look.

Carpel and fruit development genes in Solanaceae
The genetic basis underlying fruit diversity is not yet fully understood, as mainly unrelated model species have been studied. Scientists have identified in Arabidopsis major transcription

An orchid matches its scent emission rhythm to the local pollinators
Some flowers only smell at day and some only at night, but how did they evolve these different rhythms? In our study, we investigate if populations of the same orchid species that are more pollinated either at day or at night show different scent emission rhythms.

Intraspecific trait variation provides ecological opportunity for polyploids
One of the features of some plants is they can be polyploid. Humans have a pair of chromosomes carrying our genetic information. Plants can vary between

Intraspecific variability in specific leaf area and niche occupancy
How functional traits modify species niche occupancy and community assembly is a vital question in ecology. He et al. measure specific leaf area for over 5000 plants with more than 1700 observational locations.

Flexure wood is not a single tool for coping with wind strain
Investigating flexure wood, a new paper finds that the cells in a tree react to strain from wind differently depending on whether they are being stretched or compressed.

Stomatal conductance and elevated CO2
Studies have indicated that plant stomatal conductance (gs) decreases in response to elevated atmospheric CO2, a phenomenon of significance for the global hydrological cycle. However, gs

The cell biology of secondary cell wall biosynthesis
What is it that makes a plant get up and stay up? A new review looks at the creation of secondary cell walls. These microscopic features are the key to understanding the architecture of the plants we see around us.

Melatonin works with Hydrogen peroxide to induce lateral root formation
Melatonin appears to help create lateral roots, but how exactly does it do this? A team from China have been examining the connection with hydrogen peroxide.

Modelling individual kernel filling-processes with source–sink interactions
Failure to account for the variation of kernel growth may cause serious deviations in the simulation of crop yield. Ma et al. built a GREENLAB-Maize-
