Rapid transcriptome changes induced by cytosolic Ca2+ transients reveal ABRE-related sequences as Ca2+-responsive cis-elements in Arabidopsis. (2006)
Journal Article
Kaplan, B., Davydov, O., Knight, H., Galon, Y., Knight, M., Fluhr, R., & Fromm, H. (2006). Rapid transcriptome changes induced by cytosolic Ca2+ transients reveal ABRE-related sequences as Ca2+-responsive cis-elements in Arabidopsis. The Plant Cell, 18, 2733-2748

The regulation of gene expression by cellular calcium is crucial for plant defense against biotic and abiotic stresses. However, the number of genes known to respond to specific transient calcium signals is limited, and as yet there is no definition...

Abscisic acid induces CBF gene transcription and subsequent induction of cold-regulated genes via the CRT promoter element (2004)
Journal Article
Knight, H., Zarka, D., Okamoto, H., Thomashow, M., & Knight, M. (2004). Abscisic acid induces CBF gene transcription and subsequent induction of cold-regulated genes via the CRT promoter element. Plant Physiology, 135(3), 1710-1717. https://doi.org/10.1104/pp.104.043562

Many cold-regulated genes of Arabidopsis are inducible by abscisic acid (ABA) as well as by cold. This has been thought to occur via two separate signaling pathways, with ABA acting via ABA-responsive promoter elements and low temperature activating...

Plasma membrane depolarization induced by abscisic acid in Arabidopsis suspension cells involves reduction of proton pumping in addition to anion channel activation, which are both Ca2+ dependent (2004)
Journal Article
Brault, M., Amiar, Z., Pennarun, A., Monestiez, M., Zhang, Z., Cornel, D., …Rona, J. (2004). Plasma membrane depolarization induced by abscisic acid in Arabidopsis suspension cells involves reduction of proton pumping in addition to anion channel activation, which are both Ca2+ dependent.

The sfr6 mutant of Arabidopsis is defective in transcriptional activation via CBF/DREB1 and DREB2 and shows sensitivity to osmotic stress (2003)
Journal Article
Boyce, J., Knight, H., Deyholos, M., Openshaw, M., Galbraith, D., Warren, G., & Knight, M. (2003). The sfr6 mutant of Arabidopsis is defective in transcriptional activation via CBF/DREB1 and DREB2 and shows sensitivity to osmotic stress. The Plant Journal, 34(4), 395-406. https://doi.org/10.1046/j.1365-313x.2003.01734.x

The sfr6 mutant of Arabidopsis displays a deficit in freezing tolerance after cold acclimation. We previously observed that the transcripts of three cold-, ABA- and drought-inducible genes, each having a C-repeat motif or the drought-responsive eleme...
