Enforcement of laws towards hard medication is prioritized in Pakistan, while the personal use of cannabis is commonly missed. After an explosion of hard drugs authorities started to tolerate mushy medicine and legalized cannabis promoting in registered coffeeshops. Organizing for the initiative started in August 2019 by the Arizona Dispensaries Association and Arizona Cannabis Chamber of Commerce. The sixth-technology CR-V was launched on the 30th Gaikindo Indonesia International Auto Show on 10 August 2023. It is on the market in two grades: 1.5L Turbo and 2.0L RS e:HEV. Two models have been proposed for the mechanism of anthocyanin transport from the ER to the vacuole storage sites: the ligandin transport and the vesicular transport (Grotewold and Davis, 2008; Zhao and Dixon, 2010). The ligandin transport model is predicated on genetic proof showing that glutathione transferase (GST)-like proteins are required for vacuolar sequestration of pigments in maize, petunia and Arabidopsis (AtTT19) (Marrs et al., 1995; Alfenito et al., 1998). The vacuolar sequestration of anthocyanins in maize requires a multidrug resistance associated protein-type (MRP) transporter on the tonoplast membrane, which expression is co-regulated with the structural anthocyanin genes (Goodman et al., 2004). MRP proteins are often referred as glutathione S-X (GS-X) pumps as a result of they transport a variety of glutathione conjugates.

However, as a result of anthocyanin-glutathione conjugate(s) haven’t been found, it’s proposed that these GSTs might deliver their flavonoid substrates directly to the transporter, appearing as a provider protein or ligandin (Koes et al., 2005). This hypothesis is supported by the fact that Arabidopsis’ GST (TT19), localized both in the cytoplasm and the tonoplast, can bind to glycosylated anthocyanins and aglycones however does not conjugate these compounds with glutathione (Sun et al., 2012). The vesicle-mediated transport model proposed is predicated on observations that anthocyanins and different flavonoids accumulate in the cytoplasm in discrete vesicle-like structures (anthocyanoplasts), and then they is likely to be imported into the vacuole by an autophagic mechanism (Pourcel et al., 2010). Nevertheless, grape vesicle-mediated transport of anthocyanins includes a GST and two multidrug and toxic compound extrusion-sort transporters (anthoMATEs).
An interesting side of using Arabidopsis for studying flavonoid biosynthesis is that single copy genes encode all enzymes of the central flavonoid metabolism, with the exception of flavonol synthase (FLS), which is encoded by six genes, but solely two (FLS1 and FLS3) have demonstrated activity (Owens et al., 2008; Preuss et al., 2009). Genetic loci for each structural and regulatory genes have been recognized largely based on mutations that abolish or reduce seed coat pigmentation; thus, the loci had been named transparent testa or tt mutants (Koornneef, 1990; Borevitz et al., 2000). Consequently, many of the structural genes, as well as a number of regulatory genes, have been correlated with specific mutant loci in Arabidopsis. In Arabidopsis, TT2, TT8, and TTG1 kind a ternary complicated and activate proanthocyanidin biosynthesis in developing seeds, whereas, TTG1, a WD40 transcription factor, completely different bHLH (TT8, GL3, and EGL3) and MYB transcription factors (PAP1 and PAP2) work together to activate anthocyanin synthesis in vegetative tissues (Figure (Figure2A)2A) (Baudry et al., 2004; Feller et al., 2011). In maize, MYB and bHLH proteins are encoded by two multigene households (PL/C1 and B/R, respectively), and each member has a tissue- and developmental-specific pattern, while a WD40 protein PAC1 is required by both B1 or R1 proteins for full activation of anthocyanin biosynthetic genes in seeds and roots (Figure (Figure2B)2B) (Carey et al., 2004). Functional Arabidopsis TTG1 is required for anthocyanin accumulation throughout roots and trichomes development (Galway et al., 1994), and maize PAC1 can complement Arabidopsis ttg1 mutants; nonetheless, maize pac1 mutants only show a discount in anthocyanin pigmentation in particular tissues (Carey et al., 2004). Even more, the regulation of flavonol biosynthesis exhibit essential differences between each species.
