Plant metabolism is more complex relative to individual microbes. In single-celled microbes, transcriptional regulation by single transcription factors (TFs) is sufficient to shift primary metabolism. Corresponding genome-level transcriptional regulatory maps of metabolism reveal the underlying design principles responsible for these shifts as a mo...

In single-celled microbes, transcriptional regulation by single transcription factors is sufficient to shift primary metabolism. Corresponding genome-level transcriptional regulatory maps of metabolism reveal the underlying design principles responsible for these shifts as a model in which master regulators largely coordinate specific metabolic pat...

The sessile lifestyle of plants requires accurate physiology adjustments to be able to thrive in a changing environment. Plants integrate environmental timing signals to control developmental and stress responses. Here, we identified Far1 Related Sequence (FRS) 7 and FRS12, two transcriptional repressors that accumulate in short‐day conditions, as...

How a plant regulates the relationship between plant growth and plant defense is critical for understanding plant fitness or yield. Yet, little about the required complex underlying interactions are understood.... Plants integrate internal and external signals to finely coordinate growth and defense for maximal fitness within a complex environment....

A detailed understanding of abiotic stress tolerance in plants is essential to provide food security in the face of increasingly harsh climatic conditions. Glucosinolates (GLSs) are secondary metabolites found in the Brassicaceae that protect plants from herbivory and pathogen attack. Here we report that in Arabidopsis, aliphatic GLS levels are reg...

Plants integrate internal and external signals to finely coordinate growth and defense allowing for maximal fitness within a complex environment. One common model for the relationship between growth and defense is a trade-off model in which there is a simple negative interaction between growth and defense theoretically driven by energy costs. Howev...

Nitrogen is an essential macronutrient for plant growth and basic metabolic processes. The application of nitrogen-containing fertilizer increases yield, which has been a substantial factor in the green revolution¹. Ecologically, however, excessive application of fertilizer has disastrous effects such as eutrophication². A better understanding of h...

PREMISE OF THE STUDY Previous phylogenetic studies employing molecular markers have yielded various insights into the evolutionary history across Brassicales, but many relationships between families remain poorly supported or unresolved. A recent phylotranscriptomic approach utilizing 1155 nuclear markers obtained robust estimates for relationships...

Plants use diverse mechanisms influenced by vast regulatory networks of indefinite scale to adapt to their environment. These regulatory networks have an unknown potential for epistasis between genes within and across networks. To test for epistasis within an adaptive trait genetic network, we generated and tested 47 Arabidopsis thaliana double mut...

Yeast one-hybrid assays are an in vitro gene-centered approach to map transcription factor–DNA interactions. Here we describe this method and adaptations to screen for interactions between plant transcriptional regulators and their targets. Of particular note, the use of yeast one-hybrid assays fills in an important gap in available methodologies....

Efficiently obtaining and utilizing energy and elements is critical for an organism to maximize its fitness. Optimizing these processes requires precise regulation and coordination of an organism’s metabolic networks in response to diverse environmental conditions and developmental stages. Metabolic regulation is often considered to largely occur b...

Significance This research uncovers the mechanisms of an ancient arms race between butterflies and plants, seen today in countless gardens as caterpillars of cabbage butterflies that devour cabbage crop varieties. Nearly 90 million years ago, the ancestors of Brassica (mustards, cabbage) and related plants developed a chemical defense called glucos...

Camelina sativa is a Brassicaceae oilseed species being explored as a biofuel and industrial oil crop. A growing number of studies have indicated that the turnover of phosphatidylcholine plays an important role in the synthesis and modification of triacylglycerols. This study manipulated the expression of a patatin-related phospholipase AIIIδ (pPLA...

: A key unanswered question in plant biology is how a plant regulates metabolism to maximize performance across an array of biotic and abiotic environmental stresses. In this study, we addressed the potential breadth of transcriptional regulation that can alter accumulation of the defensive glucosinolate metabolites in Arabidopsis. A systematic yea...

The internal transcribed spacers of the nuclear ribosomal RNA gene cluster, termed ITS1 and ITS2, are the most frequently used nuclear markers for phylogenetic analyses across many eukaryotic groups including most plant families. The reasons for the popularity of these markers include: 1.) Ease of amplification due to high copy number of the gene c...

Cruciferous vegetables, many of which are in the genus Brassica (Brassicaceae), are prized for their nutritive value and have been cultivated for thousands of years. There are numerous wild northwestern Mediterranean species in the tribe Brassiceae, and it is therefore assumed this center of diversity is also the region of origin. Within the tribe,...

Diffuse coevolutionary interactions are thought to have driven the diversification of much of the life on Earth (Darwin 1854) and involve the evolution of key innovations (Ehrlich and Raven 1964) that may escalate in their complexity over time due to ‘arms-race’ dynamics between the interacting parties. However, the genetic basis of key innovations...

Plastids are organelles derived from free-living cyanobacteria, carrying out one of the most important biological processes, photosynthesis. Majority of the original plastid genes (estimated 2,000+) have been transferred to the nuclear genome over the past one billion years. In addition, the organization and gene content (~80-84 total) of plastid g...
