  1. Walley J, Xiao Y, Wang J, Baidoo E, Keasling J, Shen Z, et al. Plastid-produced interorgannellar stress signal MEcPP potentiates induction of the unfolded protein response in endoplasmic reticulum. Proc Natl Acad Sci U S A. 2015;112:6212-7 pubmed publisher
    ..This finding refines our perspective of interorgannellar communication by providing a link between a plastidial retrograde signaling molecule and its targeted ensemble of UPR components in ER. ..
  2. Bjornson M, Dandekar A, Chory J, Dehesh K. Brassinosteroid's multi-modular interaction with the general stress network customizes stimulus-specific responses in Arabidopsis. Plant Sci. 2016;250:165-177 pubmed publisher
    ..These results support a multi-modular interaction between BRs and stress signaling, instrumental in customizing stimulus-specific responses in Arabidopsis. ..
  3. Lemos M, Xiao Y, Bjornson M, Wang J, Hicks D, Souza A, et al. The plastidial retrograde signal methyl erythritol cyclopyrophosphate is a regulator of salicylic acid and jasmonic acid crosstalk. J Exp Bot. 2016;67:1557-66 pubmed publisher
    ..These findings identify MEcPP as a previously unrecognized central regulatory module that induces JA-responsive genes in the presence of high SA, thereby staging a multifaceted plant response within the environmental context. ..
  4. Wang C, Sarmast M, Jiang J, Dehesh K. The Transcriptional Regulator BBX19 Promotes Hypocotyl Growth by Facilitating COP1-Mediated EARLY FLOWERING3 Degradation in Arabidopsis. Plant Cell. 2015;27:1128-39 pubmed publisher
    ..This finding refines our perspective on how plants grow by providing a molecular link between COP1, ELF3, and PIF4/5 as an underlying mechanism of photomorphogenic development in Arabidopsis thaliana. ..
  5. Bjornson M, Benn G, Song X, Comai L, Franz A, Dandekar A, et al. Distinct roles for mitogen-activated protein kinase signaling and CALMODULIN-BINDING TRANSCRIPTIONAL ACTIVATOR3 in regulating the peak time and amplitude of the plant general stress response. Plant Physiol. 2014;166:988-96 pubmed publisher
    ..Collectively, these results reveal underlying regulatory components of the plant GSR and further define their distinct roles in the regulation of this key biological process. ..
  6. Wang C, Guthrie C, Sarmast M, Dehesh K. BBX19 interacts with CONSTANS to repress FLOWERING LOCUS T transcription, defining a flowering time checkpoint in Arabidopsis. Plant Cell. 2014;26:3589-602 pubmed publisher
    ..Together, these results implicate BBX19 as a circadian clock output that depletes the active CO pool to accurately monitor daylength and precisely time FT expression. ..
