New insights into the formation of silica aggregates in sorghum roots
Even though silica and lignin can provide comparable stiffness, they cannot be considered as structural equivalents due to contrasting hydrophobicity.

Polyphyly of Arundinoideae (Poaceae) and awn evolution in the grasses
This study answers one of the last remaining big questions in grass taxonomy while highlighting examples of convergent evolution in an ecologically important trait, the hygroscopic, twisted geniculate awn.

Stolon-tuber system and phylogeny of orchid-like bladderworts (Lentibulariaceae)
This study provides strong evidence, based on DNA sequences from two genomic compartments (plastid and nucleus) and morphology to group the Utricularia sect. Orchidioides into the sect. Iperua.

Modelling plant morphology: heteroblasty in epiphytic bromeliads
Self-shading may explain heteroblasty, a sudden change in form found in many angiosperms.

Serial Block Face-SEM visualisation of nuclear tubular extensions in a carnivorous plant
Unusual nuclei, with spindle-like tubular projections, in the placental tissue of Utricularia nelumbifolia may be involved in nucleus-to-cell-to-cell communication.

Creative Destruction: How Death Leads to Function
Marcos Buckeridge explains how death and destruction in sugarcane roots can lead to the development of gas spaces, which improve root function.

Anthers prominence above the corolla enhances pollinator visitation in wild radish
Why are anthers where they are? A new study finds there might be more to anthers than purely functional tools.

Start from here: SPL Theory links regenerative and life history strategies
The best chance of growing to maturity is to have the best start. A new theory connects seed and leaf size with phytomers to describe the relationship between regeneration and growth through a plant’s lifetime.

Adaptation in the root epidermis: the velamen radicum
Zotz and colleagues ask for a re-evaluation of the occurrence, evolution, and function of the velamen radicum in both terrestrial and epiphytic angiosperms

Flower-level developmental plasticity and mating system in Datura
Reductions in herkogamy with flower positions may be expected in environments with either low pollinator abundance or low nutrients.

Interactive effects of [CO2] and water availability on maritime pine
Evidence from this study indicates that elevated [CO2] not only can aggravate the effects of water deficit on photosynthetic performance and growth of maritime pine but also it can attenuate genotypic differences in drought tolerance as compared with those observed at current atmospheric [CO2].
