Mechanisms for Reorientation of Cortical Microtubule Arrays in Response to Blue Light

Plants recognize and respond to environmental cues. One such important response is directional cell growth. Genetic and pharmacological studies have shown that microtubule networks just beneath the plasma membrane play a critical role in growth polarity of plant cells through organizing the cell wall. Blue light causes a significant rearrangement of cortical microtubules in cells of dark-grown hypocotyl, in which transversely oriented microtubules are shifted to a longitudinal direction. This reorientation is driven largely by katanin-mediated severing, resulting in new growing ends at microtubule crossovers, thus amplifying longitudinal microtubules. However, little is known about the mechanisms regulating and maintaining this microtubule amplification at crossovers. We are currently investigating how crossover sites are maintained to enable katanin-mediated severing and how sites of severing are determined.
Our recent live-cell imaging and genetic studies have revealed that the SPIRAL2 protein regulates minus-end dynamics. The lack of minus end stability in spiral2 mutants reduces the lifetime of crossovers and therefore the window of opportunity for katanin activity, which results in a lower probability of microtubule severing. In this talk I will discuss how SPIRAL2 function is important for severing to occur, and the molecular mechanism regulating the site of microtubule severing.

Regulation of energy organelle dynamics in Arabidopsis

Auditorium A134, Agricultural Technology Building, Agricultural Biotechnology Research Center
2017/07/31 10:30 AM
Dr. Jianping Hu (Professor, MSU-DOE Plant Research Laboratory and Plant Biology Department, Michigan State University, USA)
Host: Der-Fen Suen
Mitochondria and peroxisomes are organelles with essential roles in energy metabolism, and act coordinately in several metabolic pathways. Components of the machineries that mediate the biogenesis and division of these organelles have been identified, yet how their functions are regulated remains poorly understood. I will present our recent work on understanding the regulatory mechanisms underlying the dynamic behavior of peroxisomes and mitochondria, including biogenesis and division/proliferation. Focus will be on the role of a small family of RING-type E3 ubiquitin ligases in protein import in multiple energy organelles. We postulate that degradation of organelle protein import factors by the ubiquitin-proteasome system may constitute an important regulatory mechanism in coordinating the biogenesis of metabolically linked organelles across eukaryotes.
