Membrane proteins are synthesized in the endoplasmic reticulum and are trafficked through the Golgi, from which they are sorted to the plasma membrane, tonoplast, or other target membranes. In all eukaryotes, secretory traffic to the plasma membrane is mediated by SNARE proteins. In Arabidopsis, three…

Many plant species actively reorient their organs in response to dynamic environmental conditions. Petiole hyponasty is an upward movement of petioles driven by a higher rate of cell expansion on the lower (abaxial) compared with the upper (adaxial) side. Hyponasty is common among rosette species facing…

Addressing fundamental questions in plant science through synthetic biology Recorded July 10, 2019  About This Webinar In this seminar, we examined the role that synthetic biology can play in answering fundamental questions in plant science. In studying plants for the past hundred years, we’ve…

Review: N-degron pathway-mediated proteostasis in stress physiology The rate of most biological processes is ultimately determined by protein activity levels, which of course are determined by rate of degradation or inactivation as well as production. Dissmeyer reviews the Cys/Arg branch of…

The rate of most biological processes is ultimately determined by protein activity levels, which of course are determined by rate of degradation or inactivation as well as production. Dissmeyer reviews the Cys/Arg branch of the N-degron pathway (previously called the N-end rule pathway) that contributes…

Interactions between plants and microorganisms occur in many different ways and on many different levels. Scientists have been attracted to this field of research because of the need to identify the agents causing infectious diseases in economically important crops. Models have been developed to describe…

Despite the widespread success of genetically modified (GM) crops resistant to herbicides and insect herbivory, GM food crops with nutritional enhancement traits remain on the fringes of commercial agriculture. In this review, Napier et al. examine the current state of GM food crops and the obstacles…

Land plants (Tracheophytes), utilize the well-developed vascular tissue for conducting water and other nutrients necessary for plant growth. In Arabidopsis and other land plants, the key player of vascular cell division is well characterized and this includes the TMO5-LHW (TARGET OF MONOPTEROS 5 –…
