According to the observations of the vertical sections of the follicle pulp of males Figure 1Dmelanin mainly transferred from the dermal papilla to the barb ridges. In contrast, in the barbules of the green parts, there were more melanosomes located under and enwrapped by the keratin layer, and they were arranged in an orderly pattern 4 layers Ethoph sexy com 1E,F.
To screen causative genes, we screened the differentially expressed genes DEGs among three comparisons: male head vs. And the barb ridges further proliferates and differentiates into the marginal plates, barbule plates, and axial plates, and finally form the mature feathers. Blonde teen stepdaughter loves a creampie maria kazi.
This site contains adult content and is intended for adults aged 18 or over. The sections were stained with L-Dopa Solarbio, China. Pretty hunk spoons playgirl to ease his cravings. Finally, the number of melanosomes was analyzed by using IPP 6. C The melanin content in the barb ridges of mallards was measured using IPP software.
B GO analysis of the genes Ethoph sexy com category In these five significant categories, the expressions of all genes were upregulated in the 7th—11th weeks and downregulated in the 11th—14th weeks. E The number of melanosomes was calculated using IPP software in the barbules of mallards. In the feathers, Ethoph sexy com, only the barbules at the top showed Ethoph sexy com coloration at the duck age of 5 weeks Figure 1Fwhich gradually changed from black to green at the ages of 6—14 weeks.
Each simplified line Ethoph sexy com shows a trend of gene expression. Illumina platform sequencing of all samples was conducted at Novogene Bioinformatics Technology Co. In total, 15 sample libraries were constructed, including 12 Kak sunflower from head skin samples three repeats from each stage of drake sampling in the 7 th11thand 14th weeks and three repeats from female mallards sampled in the 14th week and three from dorsum skin samples collected from drakes in the 14th week.
The difference in feather color Niqab Malaysia males and females revealed microscopic and anatomical observations.
The maximum likelihood ML method was used for phylogenetic analysis, Ethoph sexy com. We performed histological observations to obtain a better understanding of green feather development, Ethoph sexy com. These six species are representative avian species, and their genomes have been well annotated.
The results showed that all genes could be divided into 16 categories 0—15among which five significant types were found, including 14, Ethoph sexy com, 10, 11, 15, and 9.

D Cross-sections of the barb ridges and vertical sections of the feather follicle pulp in mallards at different growth stages. In short, feathers develop from the feather follicles. Ethiopian Petite throws it back on the bbc like a good girl 2 min. At the age of 14 weeks, less melanin was observed in follicle pulp areas, Ethoph sexy com.
Curvy brunette slut Katie Oliver touching herself on the floor. Barbule anatomy was investigated by transmission electron microscopy Xxxzzz15 using standard methods Ethoph sexy com et al. B Color changes of the head feathers in mallards at different growth stages.
The melanin content was expressed by calculating the area occupied by the melanin, which was stained dopa in the cross-section of the feather follicles, Ethoph sexy com. The feather follicles consist of the dermal papilla Slepping mom and epidermal collar, and the proliferation of the epithelial cells is active at the bottom of the feather follicles.
During the development of the feathers, epithelial cells differentiate to the barb ridges at Ethoph sexy com top of the feather follicles firstly. Taken together, we suggested that the development of green feathers may be caused by Ethoph sexy com abundant melanin transferred to the small barbules. F In Figure 1Fthe feathers were isolated from the head of male and female mallards at different growth stages.
In addition, an average of To understand the genes involved in developing green feather color on the drake head, we performed gene expression profile cluster analysis based on the transcriptome data obtained at the 7th week, 11th week, and 14th week during green head feather development.
Genome-wide gene expression trend analysis.

Hence, the transcriptomic analysis revealed that most pigmentation genes were highly expressed in feather follicles during green head feathers, contributing to melanin deposition. In contrast, others were related to receptor proteins, molecular binding, and cellular structure, Ethoph sexy com. The Y -axis coordinates of the line graph are the FPKM value, and the X -axis Ethoph sexy com are the growth stages The three nodal points in the line graph represent 7th, 11th, and 14th weeks from left to right.
The candidate genes responsible for the male green head Ethoph sexy com should explain the differences between all green and nongreen feather samples; thus, we checked the consensus DEGs among the three comparison pairs. Throughout the growth period of female mallards, the feathers in most areas were light in color Figure 1B and did not change further.
At the age of 7 weeks, intense melanin deposition was observed in the follicle pulp. Glorious babe cheating on her To hip with his friend. Lesbea Eufrat's wet pussy stretched open by big strapon.

A summary of the sequencing reads and matched genes is shown in Supplementary Table S2. After Desi x mms low-quality reads were removed, an average of 5, clean reads remained for each sample. Second, we used STEM Short time-series expression miner software to analyze the genome-wide expression trends in the partial FPKM results, including three growth stages 7th weeks, 11th weeks, and 14th weeks of drakes.
