Advances in research on the carrot, an important root vegetable in the Apiaceae family

Abstract

Carrots: past and future China accounts for nearly half of the total global production of carrots and advances in genetic technologies are contributing to improve both crop quality and yield. Cultivated carrot is the second most popular vegetable in the world after potato; this can be largely attributed to their taste and their nutritional benefits. Ai-Sheng Xiong and colleagues at Nanjing Agricultural University, China, review the latest studies on the origin and breeding of carrots. Understanding the genetic sequence and gene expression patterns in carrot plants provides valuable insights into their evolution as well as into the mechanisms underlying their resistance to disease, production of healthy carotenoids and environmental stress tolerance. Future application of gene editing technologies will help to further improve crop production and the nutritional value of carrots.
