Opinion: Information processing and distributed computation in plant organs ($) (Trends Plant Sci)

The great strides we’ve made in understanding how plants perceive their environment, from light to pathogens to nutrients, haven't been matched with an understanding of what they do with all that information; how do so many inputs get integrated into a single or few responses? And how does the information…

Special Issue: Long-distance signaling ($) (Plant Cell Physiol)

Of course plants need to communicate between their different parts, and our understanding of these crucial signals has been advancing rapidly. This issue of Plant Cell Physiology includes a set of papers highlighting recent findings. A meeting report by Kiba on the Integrative Graduate Education and…

Systemic upregulation of Zn partitioning to the shoot supplements local Zn-deficiency responses (Plant Cell)

Zinc is an important micronutrient for plants and people. To better understand Zn uptake and homeostasis, Sinclair et al. used a transcriptomic approach to identify genes abnormally expressed in zinc-transporter mutants (hma2 hma4). In these mutants, Zn accumulates in roots but isn’t effectively transported…

The spermine synthase OsSPMS1 regulates seed germination, grain size, and yield (Plant Physiol)

Polyamines including spermine and spermidine are present in all eukaryotes and have diverse roles. In plants they have been implicated in responses ranging from abiotic and biotic stresses to grain filling. Tao et al. examined the function of OsPMS1, encoding a spermine synthase, through genetic methods…

FLOWERING LOCUS T3 controls spikelet initiation but not floral development (Plant Physiol)

FT encodes a mobile protein that carries a flower-promoting signal to the shoot apical meristem. In most plants, the FT gene has duplicated and diversified. Mulki et al. investigated the function of FT3 (HvFT3) in barley. Prior work showed that overexpression of HvFT1 accellerated the initiation and…

Molecular events marking the onset of berry ripening in grapevine (Plant Physiol)

Do you know the difference between a wine made from Pinot noir grapes and one made from Cabernet Sauvignon grapes? Most people can taste a difference, but to really understand the wines you might want to go a bit deeper through metabolomic and transcriptomic approaches, as done by Fasoli et al. (in a…

Glutamate is a wound-induced signal that activates long-distance calcium signaling (Science)

Several years of intensive research have revealed a suite of mobile signals that travel long-distances to inform meristems on developmental phase transitions or to protect distal plant tissues from abiotic or biotic stressors. In a new article published in Science, Toyota et al. (2018) identify a role…
