- Hurricane Katrina's Carbon Footprint on U.S. Gulf Coast Forests - Jeffrey Q. Chambers et al. found that "[s]patially explicit forest disturbance maps coupled with extrapolation models predicted mortality and severe structural damage to ~320 million large trees totaling 105 teragrams of carbon, representing 50 to 140% of the net annual U.S. forest tree carbon sink"
- A protein key to plant virus transmission at the tip of the insect vector stylet - Marilyne Uzest et al. "report evidence for the existence, precise location, and chemical nature of the first receptor for a noncirculative virus, cauliflower mosaic virus, in its insect vector".
- Impacts of plant diversity on biomass production increase through time because of species complementarity - Bradley J. Cardinale et al. found that polycultures outperformed monocultures 79% of the time, but that "only 12% of all experiments do diverse polycultures achieve greater biomass than their single most productive species". While "a positive net effect of diversity that is no greater than the most productive species has been interpreted as evidence for selection effects... [they] show that although productive species do indeed contribute to diversity effects, these contributions are equaled or exceeded by species complementarity".
- Conifer ovulate cones accumulate pollen principally by simple impaction - James E. Cresswell et al. reports that "ovulate cones [in many pine species] structurally resemble a turbine, which has been widely interpreted as an adaptation for improving pollination by producing complex aerodynamic effects...[but they] found no evidence that turbine-like aerodynamics made a significant contribution to pollen accumulation, which instead occurred primarily by simple impaction."

- Identification of acyltransferases required for cutin biosynthesis and production of cutin with suberin-like monomers - Yonghua Li et al. report on the discovery of two enzymes essential for cutin biosynthesis in Arabidopsis.
