Abstract Cinnamomum camphora, a key multifunctional tree species, serves primarily landscaping. Leaf color, crucial for its ornamental appeal, undergoes transformation to red. However, the molecular mechanisms remain largely unexplored in C. camphora. In this study, green leaf (GL), color turning red (RL) and whole (WRL) were obtained measure pigment contents, GL RL analyzed transcriptomic alterations. A decline chlorophylls rise anthocyanins observed during from translate Using LC MS/MS, 11 kinds of showed significant accumulative differences, with Cyanidin-3,5-O-diglucoside exhibiting greatest disparity. Comparative RNA-seq identified 22,948 genes against reference genes, revealing 544 novel genes. Of these, 4,065 up-regulated 8,152 down-regulated. Among them, 22, 4, 31 differentially expressed (DEGs) associated chlorophyll biosynthesis, degradation, anthocyanin respectively. Additionally, differential expression was noted 64 bHLH, 54 MYB, 21 MYB-like transcription factors. These findings suggest strong correlation between metabolism transcriptome data release mechanism translated

Cinnamomum camphora, a key multifunctional tree species, primarily serves in landscaping. Leaf color is crucial for its ornamental appeal, undergoing transformation to red that enhances the value of C. camphora. However, molecular mechanisms underlying this remain largely unexplored. In study, green leaf (GL), turning (RL) and whole (WRL) were obtained measure pigment contents, while GL RL analyzed transcriptomic alterations. A decline chlorophyll content rise anthocyanins observed during transition from leaves. Using LC MS/MS, 11 types showed significant accumulative differences, with cyanidin-3,5-O-diglucoside exhibiting greatest disparity. Comparative RNA-seq identified 22,948 genes against reference genes, revealing 544 novel genes. Of these, 3,222 up-regulated 7,391 down-regulated when FPKM mean > 1 at least one group. The ribosome was as most abundant KEGG term, substantial number differentially expressed (DEGs). results indicated downward trend protein content, highest concentration. 22, 4, 29 DEGs associated biosynthesis, degradation, anthocyanin respectively. Most related biosynthesis down-regulated. SGR SGRL, which are exhibited opposite differential expression, resulting decrease RL. significantly ANS UFGT advantageous contributing coloration observed. Additionally, expression noted 40 R2R3-MYBs.

Abstract Background The finger lime ( Citrus australasica ), one of six Australian endemic citrus species shows a high natural phenotypic diversity and novel characteristics. wide variation unique horticultural features have made this an attractive candidate for domestication. Here we present quality, haplotype-resolved reference genome using PacBio HiFi Hi-C sequencing. Results Hifiasm assembly SALSA scaffolding resulted in collapsed size 344.2 Mb 321.1 323.2 the two haplotypes. nine pseudochromosomes had N50 35.2 Mb, 99.1% completeness 98.9% gene annotation (BUSCO). A total 41,304 genes were predicted nuclear genome. Comparison with C. australis revealed that 13,661 . These mainly involved plant-pathogen interactions, stress response, cellular metabolic developmental processes, signal transduction. genomes showed syntenic arrangement at chromosome level large structural rearrangements some chromosomes. Genetic among five cultivars was analysed. Genes related to defense, synthesis volatile compounds red/yellow coloration identified major expansion encoding thylakoid curvature proteins found Conclusions This haplotype resolved contributes our understanding evolution reveals disease resistance quality potential accelerate genetic improvement citrus.
