Robbed, yet replenished: nectar, pollination and reproduction in an alpine plant

Plant-robber-pollinator interactions are studied in an alpine plant, Salvia przewalskii, that is pollinated by long-tongued Bombus religiosus and short-tongued B. friseanus, and robbed by...

Where do Chloroplasts go to die?

Even plants find it healthy to eat their greens.

Responses of Eucalyptus globulus to eleven levels of continuous water availability

Foliar concentrations of plant secondary metabolites (PSMs) are influenced by soil water availability. However, concentrations of individual compounds in previously published studies have been...

Insect prey feeding strategies of a deep rooting dry-soil carnivorous plant

Nutrition of carnivorous plants has rarely been studied in dry-soil species with long, deep roots, with the focus hitherto on shallow-rooted genera from boggy...

Stomatal cell wall composition: distinct structural patterns in different phylogenetic groups

Stomata are pores regulating gas exchange in land plants. Stomatal morphology has remained largely consistent through ∼400 million years of plant evolution, though cell...

Tree-ring anatomy reveals climatic influence on xylem morphogenesis

During the growing season, the cambium of conifer trees produces successive rows of xylem cells, known as tracheids. Current knowledge on this process mainly...

Reducing P uptake by plants

Some things are hard to digest, but is an excess of phosphorus really one of them?

Genetic makeup of autonomous endosperm in Hieracium

Apomixis (asexual seed formation) generates clonal plants with a maternal genotype. Apomictic Hieracium subgenus Pilosella species mitotically form female gametes, with the seed’s embryo...

Glycoprotein secretions and pollen tube kinetics in apple

The obturator bridges the downward transit of the pollen tube through style to ovary in many angiosperms. Examining pollen tube growth kinetics in the...

The Final Day of #BotanyLive

Once again all times are UTC. PDT (Los Angeles, Vancouver) = UTC -7 MDT (Denver, Edmonton) = UTC -6 CDT (Chicago, Winnipeg) = UTC -5 EDT (New York,...

A key protein may help trigger germination in Arabidopsis seeds

Seed germination is a critical step in the life cycle of flowering plants. Since seeds contain limited reserves, seed germination has to...

Daffodils and Snowdrops react differently to warming seasons

Daffodils and Snowdrops need the right temperatures in a few seasons to germinate. Will a changing climate cause problems?

Changes in How a Plant Breathes Aren’t Always Matched by Changes in Its Anatomy

You can't predict how a Yucca gloriosa will react to drought from its anatomy alone.

New grapevine model better predicts whole-canopy gas exchange

Models considering only the maximum photosynthetic capacity for all leaves over-estimated net carbon dioxide exchange by nearly a third.
