Robert et al. monitor stem variations in A. marina trees in a natural mangrove forest over the course of one year, and find that patchiness occurs in both the radial growth and the shrinkage and swelling patterns of the stems.

Sousa et al. combine cytogenetics, using fluorescent in situ hybridization (FISH), and modelling of changing chromosome numbers in a maximum-likelihood framework to study Typhonium, a genus of Araceae with 2n = 24 and 2n = 8, the lowest known count in the family.

Sun et al. study structural and functional variation of FUL-like (AP1 subfamily), SEP-like and AGL6-like genes in the basal eudicot Epimedium sagittatum.

Christenhusz and Chase highlight which fern groups/genera have taxonomic issues that remain to be clarified, and propose the use of broader family concepts.

Dyson et al. study wild-type A. thaliana and a gpt2 T-DNA insertion knockout line, and find that plants lacking GPT2 expression are delayed in seedling establishment, specifically in the process of cotyledon greening (rather than germination).

Ahern and Whitney use common garden experiments with common cocklebur, Xanthium strumarium (Asteraceae), to examine relationships between stereochemical variation in sesquiterpene lactones, herbivore damage and plant fitness.

A single species of male gnat (Mycetophilidae) visits and pollinates the rewardless flowers of P. sanguinea. The gnats often show probing copulatory behaviour on the labellum, leading to its triggering and the temporary entrapment of the gnat in the flower.

Johnson et al. measure xylem embolism resistance and connectivity in roots of two co-occurring tree species in a semi-arid habitat, Quercus fusiformis and Sideroxylon lanuginosum.

Wheat is the most important food crop in the temperate world, but we know little about the gluten it contains.

Even though P. virginiana is a widespread species, fragmented populations experience significant reductions in fruit set and pollen limitation.

Soltis et al. study the impact of feeding by hemlock woolly adelgid, Adelges tsugae, on the biomechanics of eastern hemlock trees, Tsuga canadensis.

Collet et al. study a tree plantation that mixes beech and sycamore according to a double gradient of density and species’ proportion, and find that density and tree size are the primary factors determining individual growth and stand productivity.
