Wild relatives of beans retain useful drought resistance

A new study of wild crop relatives of common bean (Phaseolus vulgaris) finds they retain useful adaptations to drought stress.

Root growth and plant height connected to an auxin-related gene

What makes a plant tall? Scientists think it may be connected to a gene involved in responding to the hormone Auxin.

Stem and leaf growth rates define the leaf size vs. number trade-off

In trees, the trade-off between leaf number and individual leaf size on current year shoots (twigs) is crucial to light interception. This...

The bzh root system reacts highly economically when N is scarce

In oilseed rape (Brassica napus) bzh dwarf plants have improved nitrogen (N) uptake, N-utilization and N-use efficiency compared to normal types. Is this due to their shoots, or do roots play a role?

Drought tolerance strategies of conifer species in the northwestern US

As trees photosynthesize, using carbon from the atmosphere to grow and store energy, they also lose water to the air (transpire). During...

A new molecular mechanism reveals how plants keep their cool

How do plants adjust their body plan to cope with high-temperature stress?

Ovule and seed production patterns in relation to flower size and floral symmetry

Animal pollinated flowers show two types of floral symmetry, actinomorphy (radial symmetry) with several planes of symmetry or zygomorphy (bilateral symmetry) with...

Strigolactones interact with other plant hormones in many situations

Strigolactones are interesting phytohormones in their own right, but Luke Omoarelojie and colleagues say we should be looking at cross-talk with other hormones too.

Complex interplay of responses when plants experience canopy shading

Plants react to both decreased red:far red ratio and decreased photosynthetically active radiation, and in different ways.

Simulated Herbivory Leads Grasses to Pass Fungal Symbionts to Their Offspring

Many grasses host symbiotic fungi, Epichloƫ spp. These fungi can help grasses tolerate herbivory, or help repel herbivores. But how do these...
