Qualitative analysis of cotton fiber pigment composition
Naturally colored cotton is a green textile material. To cultivate new colored cotton and improve its performance, we must first understand the types, composition, and formation mechanism
Quantitative metabolome and transcriptome analysis reveals complex
To explore the system-wide changes of green cotton fiber in response to shading, we also analyzed gene activities in the pigment synthesis-related metabolic pathway by using RNA-seq
Integrative Transcriptomic and Metabolic Analyses
Through multidimensional transcriptomic, metabolic, and conjoint analyses of brown and white fibers, we found that the UDEGs, enriched
Variable Branching of Any Single-Mode Fiber Installed in Optical
We propose a side-polished fiber coupler in which part of the core of one fiber is removed to branch the target fibers. With this coupler, we demonstrate variable branching ratio of any single
TEXTILE DYEING
The other colorant used on textile fibers are pigments. Pigments unlike dyes, have no natural affinity for textile fibers. In order to produce permanent color on textile products, pigments are bound to the
Flavanone and flavonoid hydroxylase genes regulate fiber color
Early biochemical analysis showed that flavonoids participated in the brown coloration of cotton fibers, and then proanthocyanidins (PAs) and their derivatives were confirmed , to be
Single-cell transcriptome atlas identified novel regulators for pigment
The pigment gland of cotton is a highly distinctive structure, which provides an ideal system to study cell differentiation and organogenesis. Our study indicates that the initiation of cell differentiation of
Flavanone and flavonoid hydroxylase genes regulate fiber color
Clarifying the molecular mechanism of fiber color formation and identifying genes responsible for fiber coloration, color enrichment, and color type of NCC fiber can help us manipulate
Specific expression of a fusion gene
Our results provided a feasible strategy to promote anthocyanin synthesis and accumulation in cotton fibers, and also its side effects on fiber coloration and development, which laid
Gibberellic acid promotes single-celled fiber elongation
Our work provides an impetus for understanding GA signaling in plant development at the single-cell level and practically offers us a roadmap to
Comparison of the Properties of Natural Fiber Pigment
To compare the differences in pigment compounds in four natural fibers, as well as the differences in the dissolution of pigment components in different solvents, we conducted pigment extraction and
Combined Analysis of Transcriptomes and Metabolomes Reveals
Conclusions: Our study demonstrates that MeJA-mediated flavonoid biosynthesis, regulated by MYB transcription factors, is the central pathway controlling pigment deposition in
Characterization of Pigmentation and Cellulose Synthesis in Colored
Abstract Naturally colored cotton (Gossypium hirsutum L.) fibers (CCFs) are of interest in the textile industry because they require little dyeing and result in less environmental pollution.
