Efficient Collection of Skin Biopsies Using the Tissue Sampling Unit^® for Subsequent Cryopreservation and Culture of Fibroblasts [PDF]

Methods and Protocols
Dermal tissue samples are a rich source of germplasm because they can be readily collected, frozen as part of a genebank collection, digested and cultured, and used for a variety of purposes such as genotyping or other forms of genetic research.

TRADITIONAL PRACTICES AND GENETIC DIVERSITY ON CHAYOTE LANDRACES AND THEIR CONSERVATION [PDF]

Natural Resources and Sustainable Development, 2020
Chayote is a multi-functional crop adapted to wide range of climate with the capacity of making its products in the market all the year round. Diversity determines the breeding and conservation strategies. Diversity of chayote was assessed on-farm, and

Effects of OsAOX1a Deficiency on Mitochondrial Metabolism at Critical Node of Seed Viability in Rice

Plants, 2023
Mitochondrial alternative oxidase 1a (AOX1a) plays an extremely important role in the critical node of seed viability during storage. However, the regulatory mechanism is still poorly understood.

Distinct biological ages of organs and systems identified from a multi-omics study

Cell Reports, 2022
Summary: Biological age (BA) has been proposed to evaluate the aging status instead of chronological age (CA). Our study shows evidence that there might be multiple “clocks” within the whole-body system: systemic aging drivers/clocks overlaid with organ ...

Opening the Treasure Chest: The Current Status of Research on Brassica oleracea and B. rapa Vegetables From ex situ Germplasm Collections

Frontiers in Plant Science, 2021
Germplasm collections reflect the genetic variability in crops and their wild relatives. Hence, those genetic resources are tremendously valuable for breeders and researchers, especially in light of climatic change and stagnant crop production rates.
