Cold acclimation in pea. Lathyrus oleraceus

To understand physiological mechanisms of cold acclimation in pea, we performed a transcriptomique analysis in order to compare the response to LT treatment in two varieties, one being cold tolerant (Champagne) and the other cold sensitive (Terese). Overall design: For each genotype, course time d2, d5, d10 and d20 gene expression of each treatment (acclimated and non-acclimated) was compared with gene expression of d0 on slides.
