Using thale cress (Arabidopsis thaliana) as a model plant to study how cell patterning develops during radial growth, Dr Ari Pekka MEnhE[micro]nen's team from the Institute of Biotechnology (a HiLIFE unit) and Faculty of Biological and Environmental Sciences at the University of Helsinki has ended a near 150-year-old debate on the location and essence of the stem cells responsible for radial growth.
Laying bare several roots of how plants respond to drought, biologists at the University of Nebraska, Lincoln, have shown that mutations in two genes of Ana-bidopsis thaliana (thale cress) can stifle its development and disrupt the defense mechanisms that protect it against drought-like conditions.
(8) Arabidopsis thaliana (thale cress) is a popular model organism in plant biology and genetics carrying the aequorin gene, a gene producing the calcium-dependent bioluminescent protein aequorin to measure increased [Ca.sup.2+] in response to low level 50 Hz sinusoidal EMF exposure.
They investigated the growth behaviour of seedlings of the model plant thale cress (Arabidopsis thaliana).
The key to the supertomatoes is a protein called AtMYB12, found in the garden weed thale cress.
The research was carried out on thale cress - a model for plant research - but scientists say the mechanism they have found also exists in crops such as barley, corn, rice and wheat.
, or wild thale cress, uses its sense of daylight to build up stores of defensive, anti-insect chemicals during the night, to prepare for bug onslaughts the next day.
Using thale cress, a small flowering plant, they showed that altering a particular gene could change the speed with which chloroplasts transform into other structures in plant cells, including those involved in the ripening of fruit.
The researchers' starting point was the calcium pump located in the cell membrane of the model plant thale cress (Arabidopsis thaliana), but the regulatory mechanism also applies to the corresponding calcium pump in humans and animals.
