Article Synopsis
  • Oil-Camellia (Camellia oleifera) is a valuable oil-producing tree known for its high-quality edible oil which is rich in unsaturated fatty acids and various beneficial compounds, but its genetic complexity complicates research and breeding efforts.
  • A chromosome-scale genome assembly of the hexaploid cultivar Changlin40 has been completed, revealing 8.80 Gb of genomic data and 135,868 genes that help clarify its genetic structure and evolutionary history.
  • By integrating genomics, transcriptomics, and metabolomics, researchers identified key genes and transcription factors involved in the oil's biosynthesis, providing a foundation for future genetic enhancement and understanding of polyploid genome evolution in oil

The molecular mechanisms of freezing tolerance are unresolved in the perennial trees that can survive under much lower freezing temperatures than annual herbs. Since natural conditions involve many factors and temperature usually cannot be controlled, field experiments alone cannot directly identify the effects of freezing stress. Lab experiments are insufficient for trees to complete cold acclimation and cannot reflect natural freezing-stress responses.

Bamboo shoot is an indispensable vegetable in Southeastern China, so a survey of heavy metals in bamboo shoots is a relevant topic of interest. The present study sought to analyse the content of seven heavy metals (As, Cd, Cr, Cu, Mn, Pb and Zn) in six bamboo shoot species from Southeastern China. Percentages of 3.

To assess the adaptability of Camellia oleifera for introduction in new growth locations, this study evaluated 10 representative C. oleifera cultivars from the main areas in China where this oil-producing evergreen crop is grown. Cluster analysis, correlation analysis, and membership function analysis were used to evaluate various indices of the selected C.

Tea-oil tree ( Abel) is an important edible oil woody plant with a planting area over 3,800,000 hectares in southern China. Anthracnose is a serious disease of tea-oil tree in southern China, causing severe economic losses and posing a huge threat to the industry. Based on recent developments in the classification of species, the objective of this study was to identify species associated with tea-oil tree and examine their pathogenicity on leaves and fruits of .

The tung tree (Vernicia fordii) is one of only a few plant species that produces high oil-yielding seeds rich in α-eleostearic acid (α-ESA, 18:3Δ9cis, 11trans, 13trans), a conjugated trienoic fatty acid with valuable industrial and medical properties. Previous attempts have been made to engineer tung oil biosynthesis in transgenic oilseed crops, but these efforts have met with limited success. Here we present a high-quality genome assembly and developing seed transcriptomic data set for this species.
