Metabolite profiling and transcriptome analyses reveal novel regulatory mechanisms of melatonin biosynthesis in hickory.

Studies have shown that melatonin regulates the expression of various elements in the biosynthesis and catabolism of plant hormones. In contrast, the effects of these different plant hormones on the biosynthesis and metabolism of melatonin and their underlying molecular mechanisms are still unclear. In this study, the melatonin biosynthesis pathway was proposed from constructed metabolomic and transcriptomic libraries from hickory (Carya cathayensis Sarg.

The genomes of pecan and Chinese hickory provide insights into Carya evolution and nut nutrition.

Background: Pecan (Carya illinoinensis) and Chinese hickory (C. cathayensis) are important commercially cultivated nut trees in the genus Carya (Juglandaceae), with high nutritional value and substantial health benefits.

Results: We obtained >187.

Full-Length Transcriptome Analysis of the Genes Involved in Tocopherol Biosynthesis in Torreya grandis.

The seeds of Torreya grandis (Cephalotaxaceae) are rich in tocopherols, which are essential components of the human diet as a result of their function in scavenging reactive oxygen and free radicals. Different T. grandis cultivars (10 cultivars selected in this study were researched, and their information is shown in Table S1 of the Supporting Information) vary enormously in their tocopherol contents (0.

[Distribution of 45S rDNA sequence on chromosomes of Triticum aes-tivum and its relative species].

Fluorescent in situ hybridization (FISH) and sequential C-banding and FISH techniques were used in locating 45S rDNA sequence on specific chromosomes of Triticum monococcum, T. dicoccoides, T. aestivum, Hordeum vulgare, Haynaldia villosa, T.
