In plants, the mechanisms underlying tissue-specific gene activity remain largely unexplored. Although transcriptional and epigenetic profiling of individual organs, tissues, and more recently, of single cells can easily detect the molecular signatures of different biological samples, how these unique cell identities are established at the mechanistic level is only beginning to be decoded. Computational methods, including machine learning, used in combination with experimental approaches, enable the identification and validation of candidate cis-regulatory elements driving cell-specific expression. Synthetic biology shows great promise not only as a means of testing candidate DNA motifs but also for establishing the general rules of nature driving promoter architecture and for the rational design of genetic circuits in research and agriculture to confer tissue-specific expression to genes or molecular pathways of interest.}, journal={CURRENT OPINION IN PLANT BIOLOGY}, publisher={Elsevier BV}, author={Yaschenko, Anna E. and Fenech, Mario and Mazzoni-Putman, Serina and Alonso, Jose M. and Stepanova, Anna N.}, year={2022}, month={Aug} }
 @article{mazzoni-putman_brumos_zhao_alonso_stepanova_2021, title={Auxin Interactions with Other Hormones in Plant Development}, volume={13}, ISSN={1943-0264}, url={http://dx.doi.org/10.1101/cshperspect.a039990}, DOI={10.1101/cshperspect.a039990}, abstractNote={Auxin is a crucial growth regulator that governs plant development and responses to environmental perturbations. It functions at the heart of many developmental processes, from embryogenesis to organ senescence, and is key to plant interactions with the environment, including responses to biotic and abiotic stimuli. As remarkable as auxin is, it does not act alone, but rather solicits the help of, or is solicited by, other endogenous signals, including the plant hormones abscisic acid, brassinosteroids, cytokinins, ethylene, gibberellic acid, jasmonates, salicylic acid, and strigolactones. The interactions between auxin and other hormones occur at multiple levels: hormones regulate one another's synthesis, transport, and/or response; hormone-specific transcriptional regulators for different pathways physically interact and/or converge on common target genes; etc. However, our understanding of this crosstalk is still fragmentary, with only a few pieces of the gigantic puzzle firmly established. In this review, we provide a glimpse into the complexity of hormone interactions that involve auxin, underscoring how patchy our current understanding is.}, number={10}, journal={Cold Spring Harbor Perspectives in Biology}, publisher={Cold Spring Harbor Laboratory}, author={Mazzoni-Putman, Serina M. and Brumos, Javier and Zhao, Chengsong and Alonso, Jose M. and Stepanova, Anna N.}, year={2021}, month={Apr}, pages={a039990} }
