Open Positions

Opportunities for highly motivated and creative M.Sc. and Ph.D. students that are interested in understanding the biochemistry and physiology of plant stress response.

The lab is focused in the apex of abscisic acid (ABA) signal transduction pathway and related physiological/cellular stress response. 
We use state-of-the-art biochemical and molecular biology approaches to genetically dissect the ABA pathway as well as analytical chemistry strategies to discover novel plant hormones and growth regulators.

Research Interest


Research in the Mosquna lab is focused on plants response to environmental stress; we are interested in the apex of abscisic acid (ABA) signal transduction pathway and related cellular/physiological stress response. In addition we are kin to discover novel plant hormones and growth regulators, by an unbiased approach monitoring plant small molecule-protein interactions. Study of this regulatory scaffold is expected to be of long-term benefit to biotechnology and lead to innovations in agriculture.

 

PfFit

BACKGROUND

PfFit (ver2.01) is a three-part program for the calculation of osmotic water permeability of cell membrane (Pf) from volume changes of a spherical, wall-less cell, evoked by a non-instantaneous change of osmolarity in the external medium. The Pf calculation takes into account the rate of the osmolarity change.

It is a stand-alone MATLAB program written by Nava Moran and Menachem Moshelion, with GUI written by Roy Novik, compiled with the help of Deborah Weisman.

Major Projects

  1. The role of Solanaceae aquaporins in improving plant vigor, abiotic stress tolerance and yield production.

  2. The regulatory role of aquaporins in controlling plant cell water permeability.

  3. Developing a high-throughput automated screening system for the on-line collection and analysis of data from many plants simultaneously.  Pinpointing plants showing improved transpiration-use efficiency under normal and stress conditions at an early developmental stage.

Dr. Ittai Herrmann

My lab is the Plant Sensing Laboratory.

We use a collection of Remote and Proximal Sensing techniques and scales in the open field as well as more controlled environments, to obtain non-destructive data and imagery. A variety of techniques including Machine Learning and Image Processing are implemented.

The ability to nondestructively assess plant traits is explored and used to detect a-biotic and biotic stresses, predict yield and assess plant phenology among other applications.

Open Positions

As our lab was only recently established, on July 2012, 
we are looking for M.Sc. and Ph.D. students.
