Lateral root initiation and formation within the parental root meristem of Cucurbita pepo: is auxin a key player?

摘要

Background and AimsIn some plant families, including Cucurbitaceae, initiation and development of lateral roots (LRs) occur in the parental root apical meristem. The objective of this study was to identify the general mechanisms underlying LR initiation (LRI). Therefore, the first cellular events leading to LRI as well as the role of auxin in this process were studied in the Cucurbita pepo root apical meristem.
