The beta-2 adrenergic receptor (ADRB2) gene, located on chromosome 5q31-q32, plays a crucial role in bronchodilation by regulating airway smooth muscle relaxation through cyclic adenosine monophosphate (cAMP)-mediated signaling. Genetic variations in ADRB2, particularly + 46A > G (Arg16Gly, rs1042713) and + 79C > G (Gln27Glu, rs1042714), have been associated with altered receptor function, potentially impacting bronchodilator response to β2adrenergic receptor agonists such as salbutamol.

Consistency in taproot color from the outside to the inside is an important indicator of carrot quality. However, most carrot cultivars exhibit inconsistency in taproot color across these tissues. This difference is primarily due to variations in carotenoid content and types in non-purple carrot, though the underlying mechanism remains unclear. In this research, four red carrot cultivars 'Benhongjinshi' (BHJS), 'Dayumeirenzhi' (DY), 'Betafruit' (BT), and 'Meiguihong' (MGH) were analyzed for carotenoid content using high-performance liquid chromatography. The expression levels of genes involved in carotenoid biosynthesis were also examined. The results showed that the total carotenoid content varied among the tissues: in the periderm, 'BHJS' had 0.4244 mg/g, 'DY' 0.4955 mg/g, 'BT' 0.5229 mg/g, and 'MGH' 0.5925 mg/g; in the phloem, 'BHJS' had 0.5757 mg/g, 'DY' 0.6234 mg/g, 'BT' 0.2744 mg/g, and 'MGH' 0.3948 mg/g; in the xylem, 'BHJS' had 0.2917 mg/g, 'DY' 0.0807 mg/g, BT 0.1748 mg/g, and 'MGH' 0.1073 mg/g.
