Amplicon sequencing of microbial DNA is a gold standard for analyzing the relative abundance of microbes in host-associated microbiomes. To gain more accurate insights into microbiome changes, it is crucial to know the absolute abundance of microbes, which can be analyzed by integrating relative abundance…

Plant strengtheners, synthetic chemical elicitors, have been shown to enhance plant resistance against various insect pests without toxic effects on the environment, but evidence is lacking for a significant increase in crop growth and yield after using these elicitors. To address this, Wang et al. studied…

Plants detect microbes by pattern recognition receptors (PRRs) that sense common conserved structures called microbe-associated molecular patterns (MAMPs) and trigger the innate immunity responses. Chan et al. identified a new player in the Arabidopsis immune response known as STRESS INDUCED FACTOR 2…

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…
