Genetic studies show that some oscillating transcriptional regulators are required for periodicity in one or both developmental processes, and this molecular mechanism has characteristics that resemble molecular clock–driven activities in animal species.

A flavor network is introduced that captures the flavor compounds shared by culinary ingredients, showing Western cuisines show a tendency to use ingredient pairs that share many flavor compounds, supporting the so-called food pairing hypothesis.
An Arabidopsis Gene Regulatory Network for Secondary Cell Wall Synthesis
A protein–DNA network is presented between Arabidopsis thaliana transcription factors and secondary cell wall metabolic genes with gene expression regulated by a series of feed-forward loops to develop and validate new hypotheses about secondary wall gene regulation under abiotic stress.

The economical trade-off between physical cost and behavioral value of rich club organization in a cellular connectome confirms theoretical expectations and recapitulates comparable results from human neuroimaging on much larger scale networks, suggesting that this may be a general and scale-invariant principle of brain network organization.
NODULE INCEPTION Recruits the Lateral Root Developmental Program for Symbiotic Nodule Organogenesis in Medicago truncatula
A stele-enriched gene regulatory network in the Arabidopsis root
It is found that upstream TFs are expressed in more diverse cell types than their targets and that promoters that are bound by a relatively large number of TFs correspond to key developmental regulators.

Light is shed on the role played by experience in publishing within specific scientific journals, on the paths toward acquiring the necessary experience and expertise, and on the skills required to publish in prestigious venues, by quantifying the chaperone effect.
Widespread inter‐individual gene expression variability in Arabidopsis thaliana

Using transcriptomic approaches, gene expression variability between individual Arabidopsis thaliana plants growing in identical conditions over a 24‐h time course is analysed to shed new light on the impact of transcriptional variability in gene expression regulation in plants.
