“…Therefore, the gene expression data in leaves was used for analysis in our study. Previous studies ( Li et al, 2021a , b ) showed that Wuzhishan population has the highest cold and drought tolerance when compared with the other three populations. Thus, the gene expression data of the Wuzhishan population was used as a representative.…”

Forsythia suspensa is a famous ornamental and medicinal plant in Oleaceae. CCD family is involved in the synthesis of pigments, volatiles, strigolactones, and abscisic acid (ABA) in plants. In this study, the CCD family in F. suspensa was analyzed at the genome level. A total of 16 members of the CCD family were identified, which included 11 members of the carotenoid cleavage dioxygenases (CCD) subfamily and 5 members of the 9-cis epoxycarotenoid dioxygenases (NCED) subfamily. The expression analysis of different tissues demonstrated that three FsCCD1 genes might be involved in the synthesis of pigments and volatiles in flowers and fruits. Three CCD4 genes were effectively expressed in flowers, while only FsCCD4-3 was effectively expressed in fruits. Comparison of CCD4 between Osmanthus fragrans and F. suspensa showed that the structure of FsCCD4-1 is was comparable that of OfCCD4-1 protein, indicating that the protein might be performing, especially in catalyzing the synthesis of β-ionone. However, further comparison of the upstream promoter regions showed that the proteins have major differences in the composition of cis-elements, which might be responsible for differences in β-ionone content. On the other hand, four NCED genes were significantly up-regulated under cold stress while two were up-regulated in drought stress. The data showed that these genes might be involved in the synthesis of ABA. Taken together, our data improves understanding of the CCD family and provides key candidate genes associated with cold and drought stresses in F. suspensa.

“…Expression patterns of the CCD genes in F. suspensa under cold stress were from Wuzhishan populations at 25 and 4°C (accession no. SRX7440183 - SRX7440188 ; Li et al, 2021b ).…”

“…These differences could reflect differences in light utilization efficiency or growth ability between Tg and Sg C. japonica. A study on differences in cold responsiveness in forsythia confirmed that the high latitude population has higher carboxykinase ATP activity (Li et al, 2021). The expression level of genes related to hormone signaling was lower in Tg than Sg C. japonica.…”

Understanding the molecular mechanism of the cold response is critical to improve horticultural plant cold tolerance. Here, we documented the physiological, transcriptome, proteome, and hormonal dynamics to cold stress in temperate genotype (Tg) and subtropical genotype (Sg) populations of Camellia japonica. Tg C. japonica suffered minimal osmotic and oxidative damage compared to Sg C. japonica under the same cold treatment. Transcriptional and translational differences increased under the cold treatment, indicating that Tg C. japonica was affected by the environment and displayed both conserved and divergent mechanisms. About 60% of the genes responding to cold had similar dynamics in the two populations, but 1,896 transcripts and 455 proteins differentially accumulated in response to the cold between Tg and Sg C. japonica. Co-expression analysis showed that the ribosomal protein and genes related to photosynthesis were upregulated in Tg C. japonica, and tryptophan, phenylpropanoid, and flavonoid metabolism were regulated differently between the two populations under cold stress. The divergence of these genes reflected a difference in cold responsiveness. In addition, the decrease in the abscisic acid (ABA)/gibberellic acid (GA) ratio regulated by biosynthetic signal transduction pathway enhanced cold resistance in Tg C. japonica, suggesting that hormones may regulate the difference in cold responsiveness. These results provide a new understanding of the molecular mechanism of cold stress and will improve cold tolerance in horticultural plants.
