How can sterility make a plant more fertile?
Brian Park and colleagues have been examining a peculiar fact. A plant can increase its reproductive success by producing sterile flowers. Not all the flowers are

Does self-fertilization rescue populations or increase the risk of extinction?
Pierre-Oliver Cheptou examines two seemingly contradictory findings. Over the last 10 years, well-established patterns of evolution have emerged. First, experimental studies have shown that

The response of mesophyll conductance to short- and long-term environmental conditions in chickpea genotypes
Mesophyll conductance to CO2 (gm), which regulates the diffusion of CO2 from substomatal cavities to the sites of carboxylation, is now recognized as a significant and

Evolution of plant mating systems drives pollen limitation
Seed production of plants is rarely maximized, because it is limited by pollen receipt. Previous theories have shown that ecological mechanisms can drive the evolution of

The diversity and evolution of pollination systems in the Apocynaceae
Interactions between flowering plants and their pollinators are known to be responsible for part of the tremendous diversity of the angiosperms, currently thought to number at

Pollination quantity and purity
If you share a pollinator with another plant species in your location, is it a good idea to flower at the same time? You can only

On the origin of orphan hybrids between Aquilegia formosa and Aquilegia flavescens
The outcomes of natural hybridization are incredibly varied, ranging from hybrid speciation to extinction of parental taxa. Orphan hybrid populations or lineages are those that occur

How do pollinators paint the landscape with colour?
When you look at a patch of flowers, you often see clusters of colour. Even when a single species can have many different colours, you get

Where does scent go when attraction doesn’t matter?
Scent matters. If you’re a flowering plant, scent is an important tool for attracting pollinators. It’s no surprise that botanists see it as a

Seed characteristic variations and genetic structure of wild Zizania latifolia along a latitudinal gradient in China
Crop wild relatives are important genetic resources for crop improvement, but they can also be candidates for crop domestication. Zizania latifolia is a perennial aquatic grass

Functional significance and optical properties of floral visual signals
Many plants produce colourful flowers that play a role in pollinator attraction. These floral visual signals may have distinct optical properties that differ in biological relevance.

Vesicular transport and salt tolerance
Halophytes tolerate external salt concentrations of 200 mm and more, accumulating salt concentrations of 500 mm and more in their shoots; some, recretohalophytes, excrete salt through
