This week Nigel Chaffey finds a gentler way to kill a plant.

Holokinetic chromosomes beat selfish centromeres

In eukaryotic lineages with monocentric chromosomes, centromeres and centromeric histone H3 (CENH3) undergo a recurrent evolutionary conflict, whereby selfish centromeres subvert female meiosis, and...

Becoming a better locksmith: a new method speeds up our ability to unlock secrets of past climates

Chemical isotopes in tree rings can help us learn about past environments, but how can you extract them without interfering with measurements?

Branching patterns of monocots and dicots

Branching patterns of root systems are characterized and compared by Pagès with a set of six quantitative traits revealing interspecific variations and correlations, suggesting...

The effects of nitrogen form on root morphological and physiological adaptations of maize, white lupin and faba bean under phosphorus deficiency

Root morphological/physiological modifications are important for phosphorus (P) acquisition of plants under P deficiency, but strategies differ among plant species, and detailed studies on...

Active or passive? Specific-leaf-area plasticity responses

Liu et al. conducted a meta-analysis to test the hypothesis that shade-induced increases in specific-leaf-area (SLA) indicate an adaptive plant response to optimizing light...

1887 and all since then for Annals of Botany

Mike Jackson, former Chief Editor of Annals of Botany and AoB PLANTS has taken a look back at the past 125 of Annals of Botany, and found some tips for the future along the way.

Phylogenetic insights into the evolution of Saxifragales habitat shifts

Species-level phylogeny and habitat evolution data are applied to the hyper-diverse angiosperm clade Saxifragales to reveal that habitat shifts are very rare. Saxifragales lineages are...

Differential selection on pollen and pistil traits in relation to pollen competition in the context of a sexual conflict over timing of stigma receptivity

Sexual conflict and its evolutionary consequences are understudied in plants, but the theory of sexual conflict may help explain how selection generates and maintains...

Light partitioning in temperate rain forests

In the temperate rainforest of southern Chile, Fajardo and Siefert find that interspecific differences in the leaf mass per area (LMA) trait can explain...
