BackgroundWater scarcity has become one of the most prevalent environmental factors adversely affecting plant growth and development. Different species have developed multiple ways of drought resistance. Saposhnikovia divaricata is a commonly used traditional herb in East Asia. However, limited information is available on the drought response of this herb and further clari cation of underlying molecular mechanism remains a challenge. Methods and ResultsIn this study, a comparative transcriptome analysis was rstly conducted to identify the major pathways and candidate genes involved in the drought adaptive response of S. divaricata. The seedlings of S. divaricata were subjected to progressive drought by withholding water for 16 days followed by 8 days of rehydration. Transcriptome analysis identi ed a total of 89,784 annotated unigenes. The number of DEGs gradually increased with the deepening of drought and decreased after rehydration. GO and KEGG enrichment analysis suggested genes related to oxidoreductase activity, carbohydrate metabolism, plant hormone signaling pathway and secondary metabolism were important in drought response of S. divaricata. Speci c genes involved in ROS removal system (POD, Cu/Zn-SOD, APX), abscisic acid and jasmonic acid signaling pathway (PYL4, PP2Cs, JAR1, JAZ) and phenylpropanoid biosynthesis (4CL, CCR, CAD) underwent dynamic alterations under drought and rehydration. Finally, the expression pattern of 12 selected DEGs from the transcriptomic pro ling were validated by RT-qPCR. ConclusionsOur study laid a foundation for understanding the stress response of S. divaricata and other Apiaceae family plant at molecular level.

“…The taproot of carrots is colorful and mainly consists of white, yellow, orange, red, and purple, which is decided by accumulated pigment and content [1,[51][52][53][54][55]. The white taproot barely has carotenoids, the yellow taproot mainly accumulates lutein, the orange taproot such as 'KRD' and 'Hongxinqicun (HXQC)' is rich in lutein, α-carotene and β-carotene and the red taproot such as 'BHJS' mainly have lutein, α-carotene, β-carotene and lycopene.…”

Studying the changes of carotenoids in the taproot of carrots under salt treatment is helpful to probe the salt stress response mechanism of carrots. The carotenoid concentration and the expression profiles of 10 carotenoid-related genes were determined in two carrot cultivars with different taproot colors. Under salt stress, the biosynthesis of carotenoids in the taproot of both ‘KRD’ and ‘BHJS’ was activated. RT-qPCR manifested that the expression levels of DcPSY1, DcPSY2, DcZDS1, DcCRT1 and DcCRT2 increased significantly in both ‘KRD’ and BHJS’ under salt stress, but DcCHXE transcripts decreased and DcPDS transcripts maintained a basal level compared to that of the control. In the taproot of ‘KRD’, the expression level of DcLCYB, DcLCYE and DcCHXB1 climbed dramatically. However, there was no significant change in the taproot of ‘BHJS’. The study showed that salt stress can stimulate the biosynthesis of carotenoids. The accumulation of lutein in the taproots of ‘KRD’ and ‘BHJS’ may be mainly attributed to the variation in DcLCYE and DcCHXB1 transcripts. The increase in β-carotene accumulation is speculated to increase salt tolerance.

“…Carrot is an important vegetable crop of Apiaceae family. In addition, celery and water dropwort and coriander also belong to common Apiaceae plants [ 4 , 48 , 49 ]. In addition to having rich anthocyanins [ 7 , 11 , 50 ], carrot has many active compounds, including carotenoids, volatile oil, vitamins, dietary fiber [ 4 , 48 ] and other nutrients.…”

The taproot of purple carrot accumulated rich anthocyanin, but non-purple carrot did not. MYB transcription factors (TFs) condition anthocyanin biosynthesis in many plants. Currently, genome-wide identification and evolution analysis of R2R3-MYB gene family and their roles involved in conditioning anthocyanin biosynthesis in carrot is still limited. In this study, a total of 146 carrot R2R3-MYB TFs were identified based on the carrot transcriptome and genome database and were classified into 19 subfamilies on the basis of R2R3-MYB domain. These R2R3-MYB genes were unevenly distributed among nine chromosomes, and Ka/Ks analysis suggested that they evolved under a purified selection. The anthocyanin-related S6 subfamily, which contains 7 MYB TFs, was isolated from R2R3-MYB TFs. The anthocyanin content of rhizodermis, cortex, and secondary phloem in ‘Black nebula’ cultivar reached the highest among the 3 solid purple carrot cultivars at 110 days after sowing, which was approximately 4.20- and 3.72-fold higher than that in the ‘Deep purple’ and ‘Ziwei’ cultivars, respectively. The expression level of 7 MYB genes in purple carrot was higher than that in non-purple carrot. Among them, DcMYB113 (DCAR_008994) was specifically expressed in rhizodermis, cortex, and secondary phloem tissues of ‘Purple haze’ cultivar, with the highest expression level of 10,223.77 compared with the control ‘DPP’ cultivar at 70 days after sowing. DcMYB7 (DCAR_010745) was detected in purple root tissue of ‘DPP’ cultivar and its expression level in rhizodermis, cortex, and secondary phloem was 3.23-fold higher than that of secondary xylem at 110 days after sowing. Our results should be useful for determining the precise role of S6 subfamily R2R3-MYB TFs participating in anthocyanin biosynthesis in carrot.
