Summary: A novel thermophilic beta-carotene 15,15'-monooxygenase BCMO7211 was characterized from marine bacterium Candidatus Pelagibacter sp. HTCC7211. BCMO7211 showed broad carotenoid substrate specificity and potential for enzymatic synthesis of retinal in biotechnological applications, producing 888.3 mg/L retinal with a conversion rate of 89.0% (w/w) under optimal conditions.

Summary: This study analyzed the content and composition of carotenoids in common zinnia, and found that cyclic carotenoids were the main pigment in both cultivars, with a higher total carotenoid content in DY flowers. Several key genes related to carotenoid biosynthesis were identified and their functions were confirmed through cloning experiments.

Summary: Carotenoid-colored integuments commonly function as sexually selected honest signals because obtaining, ingesting, absorbing, metabolizing, or transporting carotenoids can be costly. Research on painted turtles shows UV sexual dichromatism and how carotenoid deprivation can change spot and stripe color.

Summary: Mesocarp color in Cucurbita maxima is determined by carotenoid contents and compositions. This study compared two inbred lines with orange and white fruit flesh colors, revealing the genetic and molecular mechanisms behind their color differences. The findings provide insights for further research on improving the quality of squash through carotenoid biosynthesis.

Summary: This study investigated the carotenoid profiles and content in 132 yellow-flesh peach cultivars with different fruit developmental periods, fruit surface indumenta, and flesh colors. The results showed large differences in carotenoid content among the cultivars, with beta-carotene being the highest. Several high carotenoid content varieties were identified. Fruit developmental period, flesh color, and fruit surface indumenta significantly influenced the levels of different carotenoids.

Summary: The deposition of carotenoids in chicken skin turns the skin color from white to yellow, and the enzyme beta-carotene oxygenase 2 (BCO2) plays a key role in this process. The concentration of carotenoids in chicken skin was measured, and significant differences in BCO2 gene expression and one SNP c.890A>G in BCO2 were found to be potentially associated with chicken skin color. The c.890A>G may be used as a genetic marker for breeding yellow skin in Chinese indigenous chickens.

Summary: Chlamydomonas reinhardtii was transformed with BKT genes from Phaffia rhodozyma (PrBKT) and Chlamydomonas reinhardtii (CrBKT), resulting in the stable transformed algal strains C18 and P1. The total carotenoid content of C18 and P1 was 2.13-fold and 2.20-fold higher than that of the WT, respectively. Transcriptome and metabolome analysis revealed that overexpression of PrBKT in Chlamydomonas reinhardtii up-regulated more genes in the carotenoid pathway metabolism compared to CrBKT, indicating a structural difference between the two BKT genes.

Summary: The study found that salt stress can stimulate the biosynthesis of carotenoids in carrots and different carrot cultivars have different responses to salt stress. The accumulation of carotenoids in the taproots of 'KRD' and 'BHJS' is mainly related to the variation in DcLCYE and DcCHXB1 transcripts.

Summary: The study found that only 43% of total carotenoids in commercial maize hybrids were bioaccessible, with the bioaccessibility of different carotenoids decreasing as the content in the grain increased. While total carotenoid content varied among different hybrids, the majority fell within lower ranges, which should be taken into consideration when formulating animal diets.

Summary: Lycopene content in tomato fruit is largely under genetic control and varies greatly among genotypes. The expression of carotenoid biosynthesis pathway genes differs significantly between high-lycopene tomatoes (HLYs) and normal tomatoes, with two downstream genes limiting the conversion of lycopene to carotenes.

Summary: Thermosynechococcus sp. CL-1 (TCL-1) has been found to efficiently utilize CO2 under extreme conditions, and its growth can be enhanced by the addition of 17 beta-estradiol (E2). Optimal growth and biomass productivity can be achieved with specific light intensity and nitrogen levels, and TCL-1 can simultaneously remove estrogen and fix CO2.

Summary: This study reveals the genetic control mechanism of the orange-fruited phenotype in a tomato elite inbred line. It is found that this phenotype is controlled by a single recessive gene, oft3, which leads to reduced carotenoid levels and an increased beta-carotene-to-lycopene ratio in fruit. The candidate gene SlIDI1, with a 116 bp deletion mutation, is identified through gene mapping and genome sequence analysis. Functional complementation and CRISPR-Cas9 knockout experiments confirm the role of SlIDI1 in controlling the oft3 locus. Further analysis shows that SlIDI1 is highly expressed in flowers and fruit, and its expression increases with fruit ripening or flower maturation.

Summary: The study found that nanoencapsulated extracts enhanced the antioxidant potential of carotenoids, but there was still some loss of beta-carotene under certain conditions. EPG was able to maintain the concentration of carotenoids in the dark and retain a high antioxidant potential.

Summary: This study investigates the role of NtCCD1 in regulating carotenoid content and ROS levels in tobacco leaves. It is found that NtCCD1 cleaves β-carotene and lycopene to produce β-ionone and pseudoionone, leading to an increase in carotenoid contents and a decrease in ROS.

Summary: The effect of microbial phytase and limestone particle size on laying hens was evaluated. It was found that the addition of a mixture of coarse and fine limestone particles increased eggshell proportion, weight, and thickness. Furthermore, the combination of phytase and the mixed limestone improved the digestibility of calcium.
