“…Chlorophyll contents were measured in the four accessions (“AC2212,” “Long Sweet,” “3501,” and “3509”) as followed by Lichtenthaler and Buschmann (2001) and Yoo et al (2013) . Fruit pericarps from three individual plants were harvested at fruit developmental stages (10 and 20 days after fruit set, mature green, breaker, 5 and 10 days after breaker, fully red).…”

Chlorophylls and carotenoids are synthesized in the chloroplast and chromoplast, respectively. Even though the two pigments are generated from the same precursor, the genetic correlation between chlorophyll and carotenoid biosynthesis has not yet been fully understood. We investigated the genetic correlation of chlorophyll and carotenoid biosynthesis during fruit ripening. Two recombinant inbred lines populations, "Long Sweet" × "AC2212" ("LA") RILs derived from a cross between Capsicum annuum "Long Sweet" with light-green and light-red fruit and C. annuum "AC2212" with dark-green and brown-fruit and "3501 (F)" × "3509 (C)" ("FC") RILs from C. annuum "3501" with dark-green and dark-red fruit and C. annuum "3509" with intermediate green and light-red fruit, were used. As the fruit ripened, three accessions produced high levels of xanthophyll. The dark-green immature fruit accumulated more total carotenoids than the light-green fruit. This trend corresponded to the expression pattern of 1-deoxy-d-xylulose 5phosphate synthase (DXS) and CaGLK2 genes during fruit development. The expression levels of DXS and CaGLK2 in the dark-green accession "3501" were significantly higher than those of "3509" and "Long Sweet" during the early stages of fruit development. Furthermore, the genotype analysis of the transcription factor controlling chloroplast development (CaGLK2) in LA RILs revealed that CaGLK2 expression affected both carotenoid and chlorophyll contents. The single nucleotide polymorphism (SNP) linkage maps were constructed using genotyping-by-sequencing (GBS) for the two populations, and QTL analysis was performed for green fruit color intensity and carotenoid content. The QTL (LA_BG-CST10) for capsanthin content in LA RILs located at 24.4 to 100.4 Mbp on chromosome 10 was overlapped with the QTL (FC15-Cap10) for capsanthin content in FC RILs. Three QTLs for capsanthin content, American spice trade association (ASTA) value, and immature green fruit color intensity were also overlapped from 178.2 to 204 Mbp on chromosome 10. At the location, 151.6 to 165 Mbp on chromosome 8, QTLs (FC15-tcar8, FC17-ASTA8.1, and FC17-ASTA8.2) for total carotenoid content Frontiers in Plant Science 01 frontiersin.org Jang et al. 10.3389/fpls.2022.922963and ASTA value were discovered, and this region contained 2-C-methyl-derythritol 4-phosphate cytidylyltransferase (MCT), which is involved in the MEP pathway. This result is the first report to show the correlation between carotenoid and chlorophyll biosynthesis in pepper. This research will expand our understanding of the mechanism of the chloroplast-to-chromoplast transition and the development of high pigment pepper varieties.

The aim of this study is to determine the dyeing temperature at which cotton fabrics will absorb the most sodium copper chlorophyll (SCC) dyestuff. Bleached 100% cotton rib knitted fabrics were dyed with SCC at different times without mordanting. The dye absorption of the fabrics was determined by a spectrophotometric method depending on the dyeing time. Firstly, SCC solutions with known concentrations were measured and the calibration (absorbance-concentration) curve was obtained. Then, the SCC concentrations remaining in the dye liquors after dyeing at different times were determined. The dye exhaustion of the fabrics was calculated using the concentrations of the dye baths before and after dyeing. Color measurements and fastness tests of the dyed samples were performed.

“…To obtain a green color, textile materials are usually dyed blue with indigo first and then, the mordanted material is dyed a second time with a yellow plant [12]. Natural green extracts consisting of chlorophyll molecules, which are abundant in all green plants, algae and cyanobacteria, are also used as fabric dyeing colorants [13,14]. Despite attempts to use chlorophyll as a natural green dye, it often yields a dull yellow or brownish color due to the loss of magnesium ions from the chlorophyll molecules during extraction and processing.…”

This study investigates the optimal dyeing concentrations of cotton, wool, and viscose fabrics with sodium copper chlorophyllin (SCC). Using SSC above the optimal concentration increases the amount of SCC in the wastewater, which is a disadvantage. Pre-finished 100% cotton, wool and viscose 1 x 1 rib knitted fabrics were dyed with varying SCC concentrations. Optimal dyeing concentrations were determined using UV-Vis spectrophotometry, showing dye absorption decreasing as SCC concentration increases. Equilibrium was reached at approximately 7 ml/L for cotton and viscose, and 3 ml/L for wool. Color measurement values and K/S values of the dyed samples were obtained according to the CIELab color system. The K/S values of dyed cotton, viscose, and wool fabrics rose as the concentration of SCC increased, reaching a peak at 9 ml/L for viscose and 12 ml/L for cotton and wool. Rubbing and perspiration fastness were rated good to excellent.
