A novel specialized immune player: BSK5 is required for restricting pathogen progression

Amna Mhamdi, Ghent University, Department of Plant Biotechnology and Bioinformatics, and VIB Center for Plant Systems Biology, 9052 Ghent, Belgium Defense reactions are the fascinating result of a complex network between signals, receptors and effectors, where any missed nodes may spell disaster.…

Pinstatic acid as a dissection tool-kit for transcriptional and non-transcriptional auxin responses

Author:         Magdalena M. Julkowska Affiliation:      Biological and Environmental Sciences and Engineering, King Abdullah University for Science & Technology (KAUST), Thuwal, Saudi Arabia   Auxin is one of the most studied plant hormones, and it comes in various forms. Whereas…

The SNARE SYP132 fine-tunes proton transporter levels at the plasma membrane during plant growth

By Lynn GL Richardson The acid-growth theory was proposed over 40 years ago based on early observations that low apoplastic pH promotes growth in a pathway involving the plant hormone auxin (Rayle and Cleland, 1992; Hager, 2003; Arsuffi and Braybrook, 2018). Since this discovery, a clearer understanding…

Found: Middle Men in the Hormone Joint Task Force

Bethany Huot, Michigan State University Driving through the country on a lazy summer day with a nice gentle breeze, the lush fields of wheat, corn and soybean appear peaceful. What you cannot see is the quiet war plants are fighting against the insects and pathogens that have pulled up to a feast…

Timing is Everything: Tandem Fluorescent Timers Expand Our Understanding of Protein Longevity

Signaling within and between cells is fast and dynamic. Such signals can involve the transport of charged ions that change membrane polarity or intercellular gradients, protein de/phosphorylation, protein interactions, and phytohormones, among others. The change in protein distribution in response to…

New interacting partners of BLADE-ON-PETIOLE in regulation of plant development

Organ boundaries are junctions that separate initiating lateral organs from the meristem or other plant parts. Cells at the boundary often exhibit slow growth rates and morphology distinct from that of the surrounding cells, and their development are controlled by complex gene networks. Lateral organ…

Light Triggers the Search for Light

Plants rely on light for photosynthesis. As a consequence, plant growth is strongly shaped by light availability, to optimize photon absorbance in the green tissues. Seedlings that germinated underground grow quickly to escape from the darkness, while plants that are threatened to be overgrown by neighbors…

Do all roads lead to 2-phenylethanol in Populus?

Plants emit scented volatile compounds to attract pollinators, or alternatively, as direct or indirect plant defense mechanisms. Direct defense involves compounds that are toxic, whereas an indirect defense uses volatiles to attract parasitoids of insect herbivores (Unsicker et al., 2009; Maag et al.,…
