Shaping the cline of floral calyx lobe length in Asarum
Divergent selection may have driven the calyx lobe length variation in series Sakawanum taxa, although the underlying mechanism is still not clear.

Carbohydrate storage and leaf biomass scaling in meadow plants
These findings imply that storage in herbs is probably governed by factors other than just the disturbance regime applied once in a growing season.

Hypericum hybrids trapped in their polyploid gene pool
The underlying genetic causes of the switch to apomixes are not yet fully understood, but in Hypericum there is good evidence for the existence of ‘apomictic factors’.

Biogeographic history and climatic niche evolution of Japanese endemic primroses
Climatic changes and historical orogenies during the Quaternary might have played a significant role in determining the speciation and diversification patterns of primroses in Japan.

Nitrogen to phosphorus ratio as a threshold for nutrient limitation in plants (Meta-analysis)
These findings highlight that canonical N:P thresholds have the potential to introduce a large uncertainty when used to detect plant nutrient limitations, suggesting that the error risks should be cautioned in future studies.

Phylogenetic and functional signals in ovular secretions of gymnosperms
This study reinforces the antiquity of insect–plant pollination mutualisms in Gnetophyta, which have a fossil record beginning in the Triassic.

Cell growth and homeostasis are disrupted in Arabidopsis rns2-2 mutants
The salvage pathway that recycles rRNA is shown to be important in maintaining normal nucleoside levels and cellular homeostasis in plants.

Carbohydrate metabolism and androdioecy maintenance in Tapiscia sinensis
Fruit ripening overlaps with flowering, leading to a severe reproductive burden on the hermaphroditic individuals.

Codon usage in non-grass monocots
Codon usage bias (also known as codon bias) is the selective use of nucleotide triplets (codons) to encode specific amino acid sequences in the protein coding

The evolution and ecology of plant architecture
Ecological factors affect the distribution of plant architectural diversity and shape its evolution, and future work integrating phylogenetically informed architectural data with ecological variables will continue to unveil how plant architecture is shaped at a global scale.

Sex-specific morphology and physiology in Ceratodon purpureus
Separate sexes and biased sex ratios are common in bryophytes, yet little is known about how fine-scale, sex-specific morphological traits are correlated with physiology

Shoot apical meristem and plant body organization: a cross-species comparative study
The shoot apical meristem (SAM) is the key organizing element of the plant body. Surprisingly, there are almost no across-species comparative data showing links between
