Team Finds How Plants Make Aerial Roots

6 March, 2022

JUST LOOK UP!   Team Finds How Plants Make Aerial Roots

(Jerusalem, March 3, 2022)—Sometimes, to see the roots, you have to look up.

Roots are normally associated with things that live underground, in the damp and the dark. Think of turnips, radishes and yams. However, many plants make their roots above ground.  Ivy uses its roots to climb on buildings and the mighty ficus tree uses them to support their large branches.  What makes plants form roots in the “wrong place,” so to speak? That would be like us humans sprouting legs from our shoulders.

In a study published this week in the prestigious journal Science, Hebrew University of Jerusalem (HU) Professor Idan Efroni and his team found the hidden mechanism that enables aerial roots to happen. By decomposing the stem to individual cells, the team identified the extremely rare cells that, when conditions are ripe, cause roots to grow in the air.

Special Interests and Achievments

  • Basic genetics and physiology studies of the spontaneous mutations of ripening inhibitor genes in tomatoes and the consequent exploitation of the knowledge resulted in the original development of long shelf-life tomatoes, thus revolutionizing the fresh market industry.

Research Interests

Wheat production under climate changes: The highly variable and unpredicted rainfall within and between seasons, which characterize the Mediterranean region, results in significant yield losses. Our research focuses on improving wheat production under changing climate.

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.

 

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.

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.
