Taken together, the four key genes NtCHS, NtF3'H, NtDFR and NtANS were greatly upregulated in petals and filaments of Lc-transgenic lines, which resulted in enhanced anthocyanin biosynthesis and more intense pigmented calyx, petals and filaments in the Lc-transgenic lines.
Enhanced abundance of the CHRC protein has been found in all tomato hp and Intense pigment mutants, which suggests a mechanism for the coupling increased plastid number and size with enhanced carotenoid accumulation in these high-pigment tomato fruits.
Plants growing under outdoor conditions during cold winter or hot summer days showed accumulation of intense red pigments, mainly on the upper, adaxial sides of the fronds (Additional file 1).
The intense blue pigment could soon be appearing in paints, dyes, and more.
Fermentation of the Couroupita guianensis fruit pulp for 5 days gave intense bluer pigment and hence was selected as the optimum period for fermentation.
Fermentation of the Couroupita guianensis fruit pulp for 5 days gave intense blue pigment and hence was selected as the optimum period for fermentation.
Scientists have long known the two chief ingredients of the intense blue pigment: indigo, a plant dye that's used today to color denim; and palygorskite, a type of clay.
Although the yield of crude dye obtained for different fermentation period was practically same as shown in Table 1, intense bluer pigment was obtained only when the fruit pulp was fermented for 5 days.
The smolting process in lacustrine sockeye salmon is not well understood; however we have found that the body color of one-year-old fish is silver and their fins are clear with intense black pigment in May, the condition factor (CF) is significantly low in May and June (Figure S1), and serum thyroxine (T4) levels peak in May (Figure S2).
In individual chondrocytes, an intense nuclear pigment deposition was visible: nuclei showed remarkable differences from normal chondrocytes, being pyknotic and frequently condensed and irregular (Fig. 6B).
