Arabidopsis phenotyping for drought responses
Developing plants that deliver adequate yield at low water demand is a central goal in plant breeding. Working towards this aim it is essential to understand mechanisms how plant physiology operates to deal with water limitation and thus how plants survive drought events. Two mutants with contrasting drought sensitivity and the Col-0 ecotype were subjected to water limitation while growing on two differnt substrate types. Phenotypic traits were measured with a Lab Scanalyzer HTS with visual light, near-infrared and fluorescence cameras. Differential responses of plant growth to water limitation was genotype- and substrate- dependent. NIR signals indicated that in the drought-sensitive genotype tissue water content decreased faster compared to the non-sensitive mutant or Col-0.
