Transcription factors in plants and ABA dependent and independent abiotic stress signalling (2010, background): “The los5 (low expression of osmotic responsive genes) mutation reduces the induction of several stress-responsive genes by cold and severely blocks the induction of RD29A, COR15, COR47, RD22 and P5CS by osmotic stresses (Xiong et al. 2001).”
Cold stress tolerance mechanisms in plants. A review (2010, background): “…mutants defective in the activation of the molybdenum cofactor of abscisic aldehyde oxidase, namely aba3 / freezing sensitive 1 ( frs1 ) (Llorente et al., 2000), also known as los5 (low expression of osmotically responsive genes 5) (Xiong et al., 2001), exhibit hypersensitivity to freezing stress.”
Gene regulation during cold acclimation in plants (2006, background): “Thus, ABA plays a significant role in cold acclimation of plants (Xiong et al. 2001a).”
Molecular genetic perspectives on cross-talk and specificity in abiotic stress signalling in plants. (2003, background): “Therefore, although ABA-independent pathways may exist, an ABA-dependent signalling pathway plays an essential role in stress-responsive gene expression during osmotic stress (Xiong et al., 2001a).”

Abscisic Acid Signaling and Abiotic Stress Tolerance in Plants: A Review on Current Knowledge and Future Prospects (2017, background): “As DREand ABRE-like cis elements are promoters of stress-inducible ABA genes (Xiong et al., 2001; Bray, 2002), consequently, these genes are in the same way controlled as DRE/CRT class of stress-responsive genes (Xiong et al., 2002b).”
Regulatory network of gene expression in the drought and cold stress responses. (2003, neutral): “The loci of the mutations, such as fiery1 ( fry1) [46], fry2 [47,48], hos1 [49], los1 [50], los2 [51], los5/aba3 [52], los6/aba1 [53] and sad1 [54], have been cloned.”
Abscisic acid biosynthesis and catabolism. (2005, background): “However, the expression of the two other genes, AAO3 and AtABA3, involved in the conversion of abscisic aldehyde into ABA, is upregulated under osmotic stresses (122).”
Transcriptional regulatory networks in cellular responses and tolerance to dehydration and cold stresses. (2006, background): “Among them, AtNCED3 for 9cis-epoxycarotenoid dioxygenase (42), AAO3 for abscisic aldehyde oxidase (97), AtABA3 for MoCo sulfurase (123), and AtZEP (121) for zeaxanthin epoxidase are upregulated by dehydration, but AtABA2 is not.”
