TL;DR: The role of seed exchange networks in the preservation and adaptation of crop specific and genetic diversity is discussed in this article, where the authors advocate a diversity of approaches to foster the creation of robust and policy-relevant knowledge.

TL;DR: Investigation of transcriptional regulation of carotenoid biosynthesis genes in relation to carOTenoid accumulation during early carrot root development and up to 3 months after sowing showed that the accumulation of total carotanoids during development and the collection of major carotnoids in the red and yellow cultivars might partially be explained by the transcriptional level of genes directing theCarotenoids biosynthesis pathway.

TL;DR: This review begins by illustrating how interdisciplinary approaches combining ethnobotany and genetics helps provide a detailed analysis of the role of social and genetic dynamic interactions related to seed exchanges in traditional farming systems with farmer-led on-farm conservation.

TL;DR: An important result is that the genetic diversity conserved on farm is complementary to that found in the genebank indicating that both systems are required for a more efficient crop diversity conservation.

TL;DR: Results from these studies show that on-farm DM is a key element for the long-term conservation and use of agricultural biodiversity, and this method of in situ conservation deserves more attention in industrialised countries.
