The Max Planck Institute of Molecular Plant Physiology (Germany) investigated the evolutionarily-conserved proteins REIL 1 and 2 in A. thaliana and yeast cells. Research suggests these proteins are involved in the eukaryotic ribosomal 60S subunit. Here, investigators studied mutated REIL proteins in different species. The Cellometer Auto M10 analyzed cell size and concentration. The group discovered that these proteins are necessary to allow A. thaliana to grow in lower temperatures.
