Article Synopsis
- Actinidia arguta is a widely distributed species known for its small, smooth fruit, rapid softening, and strong cold tolerance, distinguished from the cultivated Actinidia chinensis.
- Researchers created a detailed genome assembly of A. arguta, which is 2.77 Gb long and organized into 116 pseudo-chromosomes, revealing two distinct geographic groups based on evolutionary divergences.
- The study identified three key genes that contribute to fruit softening and explored the genetic basis of traits related to sexual dimorphism, providing a foundation for future research and agricultural enhancement of this species.
Article Synopsis
- Anthocyanins, which give red-fleshed kiwifruit its color, are affected by high temperatures, yet their trafficking in plants hasn't been well researched.
- A study found that temperatures above 25 °C inhibit anthocyanin accumulation in the 'Hongyang' kiwifruit by affecting gene expression related to color formation.
- Cell structure analysis revealed that high temperatures hinder the formation of anthocyanin-related structures in fruit cells, indicating that multiple mechanisms are at play in how heat impacts coloration in red-fleshed kiwifruit.
The SMART switching mechanism at 5' end of the RNA transcript technique was used to construct a cDNA library from inner pericarp of the red flesh kiwifruit Actinidia chinesis cv 'Hongyang'. Construction of cDNA library facilitated cloning of the genes associated with the secondary metabolism, the specific genes in the course of anthocyanin biosynthesis. The titers of the primary library and the amplified library were 6.
