Predicting Gene Regulatory Networks
Research, The Plant Cell, The Plant Cell: In a NutshellZhou et al. develop and test potential gene regulatory networks in maize. Plant Cell https://doi.org/10.1105/tpc.20.00080
By Peng Zhou and Nathan Springer
Background: Transcription factors (TFs) play critical roles in regulating the expression of genes. A single TF can control the expression of…

The xerobranching response represses lateral root formation when roots are not in contact with water (Curr. Biol. - $)
Plant Science Research WeeklyRoots navigate through the soil, foraging for water and nutrients. Orman-Ligeza et al. observed that lateral root development is repressed when the roots are growing through the soil air spaces. Exposure to water deficit induced transcriptome reprogramming in barley roots of genes involved in many hormone…
