The pineapple reference genome: Telomere-to-telomere assembly, manually curated annotation, and comparative analysis.

Pineapple is the third most crucial tropical fruit worldwide and available in five varieties. Genomes of different pineapple varieties have been released to date; however, none of them are complete, with all exhibiting substantial gaps and representing only two of the five pineapple varieties. This significantly hinders the advancement of pineapple breeding efforts.

The Synergistic Mechanism of Photosynthesis and Antioxidant Metabolism between the Green and White Tissues of var. Chimeric Leaves.

var. () is a typical leaf-chimeric ornamental plant. The chimeric leaves are composed of central green photosynthetic tissue (GT) and marginal albino tissue (AT).

Unveiling the molecular mechanism involving anthocyanins in pineapple peel discoloration during fruit maturation.

Peel color is a key factor that affects the fruit's aesthetic and economic values. Limited knowledge is available on the regulation of pineapple peel discoloration. Here, we report that a decrease in anthocyanin biosynthesis, particularly cyanidin, is predominantly associated with the pineapple peel color change during maturation.

Methylation Analysis of CpG Islands in Pineapple Promoter.

Somatic embryogenesis (SE) is a more rapid and controllable method for plant propagation than traditional breeding methods. However, it often suffers from limited efficiency. promotes SE in several plants, including pineapple ( L.

Identification of an Embryonic Cell-Specific Region within the Pineapple Promoter.

Plant tissue culture methods, such as somatic embryogenesis, are attractive alternatives to traditional breeding methods for plant propagation. However, they often suffer from limited efficiency. Somatic embryogenesis receptor kinase ( is a marker gene of early somatic embryogenesis in several plants, including pineapple.

Development of an enzyme-linked immunosorbent assay and a dipstick assay for the rapid analysis of trans-resveratrol in grape berries.

trans-Resveratrol, a natural polyphenol present in grapes, has many beneficial effects to human health. However, measurement of trans-resveratrol is technically complicated and time-consuming. In the present study, we obtained a sensitive and specific monoclonal antibody (mAb), namely 3C9, against trans-resveratrol.

Genetic Diversity in Various Accessions of Pineapple [Ananas comosus (L.) Merr.] Using ISSR and SSR Markers.

Inter simple sequence repeat (ISSR) and simple sequence repeat (SSR) markers were used to assess the genetic diversity of 36 pineapple accessions that were introduced from 10 countries/regions. Thirteen ISSR primers amplified 96 bands, of which 91 (93.65%) were polymorphic, whereas 20 SSR primers amplified 73 bands, of which 70 (96.

Development of pineapple microsatellite markers and germplasm genetic diversity analysis.

Two methods were used to develop pineapple microsatellite markers. Genomic library-based SSR development: using selectively amplified microsatellite assay, 86 sequences were generated from pineapple genomic library. 91 (96.
