A shoot shouldn't become a flower too early, but needs some control over when the process happens. A paper in JXB finds the genes responsible.

Effect of aperture number on pollen performance in Arabidopsis thaliana
Triaperturate pollen is the most conspicuous synapomorphy of the highly successful eudicot clade. It was previously suggested that this pollen morphology represents the major evolutionary adaptation, and that the stasis...

Rare soil bacteria affect plant performance
It is not known how loss of rare soil microbes affects plant defence against aphids. Kurm et al. inoculated soil with a serial dilution of a microbial community and a presumed plant beneficial bacterium (Pseudomonas...
Non-Specific Phospholipase C2 (NPC2) in plant immune responses in Arabidopsis
The non-specific phospholipases C (NPC) are recently discovered new subclass of plant phospholipases. Most of them have not yet been characterised thoroughly. Krčková et al. prepare and purify Arabidopsis thaliana NPC2...
The benefits of sleeping in
The early bird catches the worm, but does the frost catch the early plant? A new article in AmJBot says there are advantages for a plant to germinate late.

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.
Suppression of Brassica fungal pathogens by Bacillus amyloliquefaciens
Novel forms of potentially antifungal linear fengycins may serve as a basis for the development of more powerful plant protective agents.
What! Plants can hear water???
The idea that plants can hear is controversial, but Nigel Chaffey finds the evidence keeps building.

Intra-specific variation in Arabidopsis functional strategies
Considerable intra-specific variation in functional strategies can occur within a single plant species. C-S-R theory was developed to classify functional strategies (competitive, stress tolerant, ruderal) in different...
Germination responses to pre-dispersal light and post-dispersal cues
Should seeds respond to their parents’ environments or their own? Leverett et al. hypothesize that germination would respond more strongly to a post-dispersal vegetative canopy than a pre-dispersal canopy, because a...
The role of XAL1 in the root cell dynamics underpinning root growth
Morphogenesis depends on the modulation of cell proliferation and differentiation. The reverse genetics approach of García-Cruz et al. reveals that such modulation is dynamically adjusted in response to various signals...
Mapping developmental zones at the root apex using the multiple structural change algorithm
In the root apex, cell length is a function of its position within a cell file. Applying a mathematical approach using a multiple structural change (MSC) algorithm, Pacheco-Escobedo et al. developed a spatial model to...
Stochastic variation in Cardamine hirsuta petal number
Petal number is a robust trait in flowering plants. Crucifer flowers have four petals but Monniaux et al. show that petal number varies from zero to four in Cardamine hirsuta. They mapped quantitative trait loci...
Reproductive organ and young tissues show constrained elemental composition
Current knowledge of plant stoichiometric homeostasis is mainly obtained from the mature leaf, with little from other organs across different developmental stages. Yan et al. conducted a greenhouse nitrogen (N) and...
