In this review Stewart et al. address the potential use of houseplants as biosensors for harmful agents in the home environment, taking advantage of phytosensor technology already in use in agricultural settings. The authors propose the design of genetically modified plants that carry a synthetic promoter…

The diverse responses of rice to flooding are really interesting. Many varieties die, some survive by essentially becoming metabolically quiescent to conserve their energy (which involves the Sub1 pathway), and some, called deepwater rice, respond through rapid elongation that elevates their leaves above…

Cryptochromes (CRYs) are blue-light receptors that were first identified in plants more than 20 years ago, but with modes of action that have remained obscure. Yang, Mo, and Yu, et al. reassembled this blue-light signaling module in mammalian cells in order to better understand CRY function. Previously,…

Gene knock-outs and overexpression studies are useful indicators of gene function, but can obscure the gene’s distinct cell-type specific functions. Schürholz and Lopez-Salmeron et al. have developed a set of constructs that allow for precise expression of a gene-of-interest in subsets of cells, accompanied…

Light is arguably one of the most important signals recognized by plants. Not surprisingly, plants exhibit a wide range of light responses, ranging from cell-specific to large-scale. Küpers et al. review these responses, with an emphasis on their spatial scales. For example, the production of extrafloral…

There is not much available information regarding the evolutionary aspects of one of the most studied pathosystem in plant biology: Arabidopsis thaliana and Pseudomonas. Karazov et al. performed various surveys in Arabidopsis wild populations, for the detection and characterization of their associated…

Auxin and cytokinin play critical roles in determination of cell fate in the shoot apical meristem (SAM). Until now auxin's role was thought to be confined to the peripheral zone (PZ), promoting cell differentiation and organogenesis, mediated by AR5/MP. However, studies using GC-MS have shown the presence…

The diploid strawberry (Fragaria vesca) is a useful model system for understanding non-climacteric ripening and seed-to-fruit cross-tissues communication. Previously, spatial and temporal transcriptome data from the strawberry fruit and flowers was generated. Shahan and colleagues combine the transcriptome…
