Sexual organ reciprocity in distylous primroses

The main morphological characteristic of heterostyly is the reciprocal placement of anthers and stigmas in two distinct floral morphs; however, the partitioning of reciprocity...

Tentacular spectacular

All plants are fascinating, but some are more fascinating than others (to misquote George Orwell, English novelist and journalist). And what is more fascinating...

A Slice of the Wheat Genome 

Considered by some to be the Mount Everest of crop genomes, the challenging wheat genome is close to being scaled. An international team has...

How do cacti have sex? 

You might think the answer is "very carefully", but in the case of Opuntia fragilis, it turns out to be "not at all". Considering its...

Seed ageing at elevated oxygen pressure

Subjecting seeds to elevated oxygen concentrations may provide a novel method for studying ageing processes. Groot et al. test this hypothesis by storing dry seed...

The fruit-fly and the cactus

Aesop (slave and story-teller believed to have lived in ancient Greece 620–560 BC(E)) is credited with many fables that delivered morality tales, etc. But...

Message to all students

So, you want to earn a lot of money after you graduate to pay off all those debts, right? In that case, according...

Rate heterogeneity of holoparasitic Balanophora

The substitution rates of chloroplast and mitochondria genes sometimes show tremendous variation in parasitic plants, but it is unclear if this is also true...

Gene flow in mountain environments

Responses of high-mountain plant species to global change are highly influenced by the genetic background of the species, including genetic diversity or gene flow...

Seed dormancy distribution and ecology

In sea beet, Beta vulgaris ssp. maritima, seed dormancy largely controls germination timing, is highly heritable and varies geographically; climate might select for this...

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...

Simulating the effects of local adaptation and life history on the ability of plants to track climate shifts

Local adaptation is common but not universal in plants and results from the interplay of gene flow with natural selection. Gene flow...

What creates Gentiana diversity in mountains?

The Qinghai-Tibetan Plateau (QTP) is extremely rich in species, but why? One recent explanation is the mountain‐geobiodiversity hypothesis (MGH) by Mosbrugger et...
