Association between community assemblage of flower colours and pollinator fauna

Flower colour plays a major role in the attraction and decision-making of pollinators. Different functional groups of pollinators tend to prefer different flower colours,...

Exploration of cotton leaf curl virus resistance genes in Gossypium arboretum

Cotton leaf curl virus (CLCuV) is one of the major limiting factors in cotton production systems worldwide. The widely cultivated cotton species, Gossypium hirsutum,...

Auxin transport and stem vascular reconnection – has our thinking become canalized?

The presence of a polar auxin transport stream has long been correlated with the differentiation and patterning of vascular cells across vascular plants. As...

Remote tropical island colonization does not preclude symbiotic specialists

For symbiotic organisms, their colonization and spread across remote oceanic islands should favour generalists. Plants that form obligate symbiotic associations with microbes dominate island...

Detecting canalization and intra-floral modularity in triggerplant (Stylidium) flowers

The Berg hypothesis proposes that specialized-flower traits experience stronger stabilizing selection than non-floral structures and predicts that variation in specialized-flower traits will be mostly...

Flood tolerance in two tree species that inhabit both the Amazonian floodplain and the dry Cerrado savanna of Brazil

Comparing plants of the same species thriving in flooded and non-flooded ecosystems can help to clarify the interplay between natural selection, plant plasticity and...

Development in embryonic leaves of Setaria viridis

Setaria viridis is being promoted as a model C4 photosynthetic plant because it has a small genome (~515Mb), a short life cycle (~60d) and...

Snails use smell to select seedlings of favoured grassland species

Although Darwin recognised long ago the destructive impact that snails and slugs have on seedlings, we understand remarkably little about why these herbivores select...

Plants grow in winter on the eastern Qinghai-Tibetan Plateau

Alpine plants growing on the Eastern Tibetan Plateau were thought to senesce or lie dormant during the winter, but after 4 years of field...

Floral mimicry of Faboideae in an Australian orchid

While there is increasing recognition of floral mimicry in plants, there are few cases where any explanatory mechanism is confirmed. Scaccabarozzi et al. test...

Phylogeny, age and adaptive evolution of genus Allium

The genus Allium L., one of the largest monocotyledonous genera and one that includes many economically important crops with nutritional and medicinal...

Plants from different climates can react to drought in similar ways

How do plants react when circumstances change? One method can be to evolve a local adaptation. Another can be be phenotypic plasticity,...

Not All Pine Needles Are Identical: Lower Crown Loss in Pinus radiata

When fungal infection comes to Pinus radiata, it can run through the bottom of the crown of the tree, removing its leaves....

How do you get more DNA down a pollen tube?

A common event for flowering plants is whole genome duplication (WGD), where a plant gets extra chromosomes. It’s often studied in mature...
