Some trees can save effort when it comes to adding growth rings
Sometimes it’s easy to oversimplify plant anatomy. For example, trees don’t have blood. They have sap. It might be tempting to say that they

A new code to decipher phytoliths
Plants don’t have skeletons, but they still have a mineral component in them. Inside plants you can find phytoliths, microscopic mineral deposits that a plant

Two reciprocal translocations in the burmannica group of M. acuminata
Banana cultivars are derived from hybridizations involving Musa acuminata subspecies. It divided into half a dozen or so subspecies. The current thought on domestication is that

The role of pollinator preference to maintain pollen colour variation
You’re familiar with the idea that pollinators look at flower colour, but what about pollen colour? New research shows pollinators may have a much more significant influence than thought.

Hormone-metabolic interactions in adventitious roots
Adventitious roots are roots that form after the plant embryo has grown. They’re the roots that can grow out of stems when you make plant

Relationship between duration of cell differentiation and xylem traits
Secondary growth is a process related to the formation of new cells that increase in size and wall thickness during xylogenesis. Temporal dynamics of wood formation

Ant pollination in Brazilian savanna
Ant–plant associations are widely diverse and distributed throughout the world, leading to complex ecological networks. Regarding ant–plant mutualism, ant pollination is a very rare

An inverse stomatal frequency–pCO2 correlation for Quercus glauca
The inverse correlation between atmospheric CO2 partial pressure (pCO2) and stomatal frequency in many plants has been widely used to estimate palaeo-CO2 levels. However, apparent

Mechanisms of reproductive interference in Taraxacum
Reproductive interference can reduce fitness of either of the involved species, and its ecological and evolutionary consequences may depend on its underlying mechanisms.

Larger apples have lower natural defences against pests
Botanists find a clear trade-off between fruit size and phytochemical production, helping to explain why our modern varieties are highly susceptible to diseases and pests.
