Mimicking pollen and spore walls
The exine, or outer layer of a pollen grain or spore, is extremely varied in structure. Decades of research have attempted to discover the underlying developmental

Hypernodulating soybean mutant line nod4 lacking ‘Autoregulation of Nodulation’ has limited root-to-shoot water transport capacity
Although hypernodulating phenotype mutants of legumes, such as soybean, possess a high leaf N content, the large number of root nodules decreases carbohydrate availability for plant

Does evidence of saltwater exposure explain recent changes in the tree communities of North Carolina’s Coastal Plain?
Coastal plant communities globally are highly vulnerable to future sea-level rise and storm damage, but the extent to which these habitats are affected by the

Modelling tiller growth and mortality as a sink-driven process using Ecomeristem
Plant modelling can efficiently support ideotype conception, particularly in multi-criteria selection contexts. This is the case for biomass sorghum, implying the need to consider traits

Leaf heteroblasty in Passiflora edulis as revealed by metabolic profiling and expression analyses of microRNAs
Juvenile-to-adult phase transition is marked by changes in leaf morphology, mostly due to the temporal development of the shoot apical meristem, a phenomenon known

Effects of increased precipitation on life history traits of the cold desert annual Erodium oxyrhynchum (Geraniaceae)
Due to climate warming, the global and regional water cycle is changing, and this will have a great impact on terrestrial ecosystems. Since plants are a

Investigating the diet of carnivorous plants
Earlier this year we reported on how it looked like bladderworts were farming their food, as much as hunting it. A paper submitted before those came out adds to the story, by examining the ‘trophic level’ of bladderwort and butterwort prey.

Completing the hybridization triangle: the inheritance of genetic incompatibilities during homoploid hybrid speciation in ragworts (Senecio)
Hybridization is an important contributor to biodiversity and speciation, with approximately 25 % of all plant species and 10 % of all animal species estimated to have experienced

FSPM-based investigation of plant interactions in complex wheat canopies
Functional–structural plant models (FSPMs) explicitly describe individual plant architecture, making this approach suitable for unravelling plant–plant interactions in complex canopies. Barillot et al. developed

Sink-source imbalance and down-regulation of photosynthesis
Sink-source imbalance could cause accumulation of total non-structural carbohydrates (TNC) and down-regulation of photosynthesis. Sugiura et al. investigate how sink-source imbalance causes

Beauty is in the nose of the beholder
It’s no surprise that a flower releases scent to attract a pollinator, but why would it do it hours before the pollinator is around? New research finds scent can have more than one job.
