A selective autophagy cargo receptor NBR1 modulates abscisic acid signalling in Arabidopsis thaliana.

The plant selective autophagy cargo receptor neighbour of breast cancer 1 gene (NBR1) has been scarcely studied in the context of abiotic stress. We wanted to expand this knowledge by using Arabidopsis thaliana lines with constitutive ectopic overexpression of the AtNBR1 gene (OX lines) and the AtNBR1 Knock-Out (KO lines). Transcriptomic analysis of the shoots and roots of one representative OX line indicated differences in gene expression relative to the parental (WT) line.
