The plant immune system has been a keenly researched area in plant sciences in the past decade. Elicitors present in microbes are compounds that induce response from plants when under attack. These elicitors are conserved in many pathogens and are called microbe associated molecular patterns (MAMPs).…

Shade avoidance is a complex phenomenon in which plants avoid shade by altering their developmental program in various ways including early flowering, hypocotyl elongation, and more. Many photoreceptors and transcription factors (TFs) are involved in regulating shade avoidance, including the bHLH (basic…

Plants can increase their growth and biomass proportionately to an increase in nutrient dose and, conversely, their growth is limited by limiting nutrients. In this study, Swift et al. explored the molecular underpinnings of the nutrient dose-response phenomenon. The authors first show that nitrogen-dose…

Auxin forms spatial gradients that are implicated in organ morphogenesis. However, it is not known how temporal auxin gradients are integrated with the spatial information. In this paper, Galvan-Ampudia, Cerutti et al., showed using a ratiometric quantitative auxin reporter (quantitative DII-VENUS) that…

Auxin controls virtually all facets of growth and development. This plant hormone is sensed by TIR1/AFB F-box receptors which promote ubiquitin-mediated degradation of AUX/IAA transcriptional repressors, releasing ARF transcription factors from inhibition. Phylogenetic analyses divide the ARF family…

Synthetic genetic circuits allow the reconstruction of metabolic pathways in plant systems for production of many natural products including pharmaceuticals. A challenge in genetic engineering these circuits is precisely and predictably regulating gene expression, especially when genes may be desired…

Originating in China’s Yangtze Valley ~9,000 years ago, rice (Oryza sativa) is a staple food for over half of the world’s population. While rice domestication has been well-researched, studies addressing the species' diversification and spread post-domestication are lacking. Here, Gutaker et al. tell…
