Calcium levels modulate embryo yield in <i>Brassica napus</i> microspore embryogenesis.

ABSTRACT: Calcium (Ca²⁺) is a universal signaling cation with a prominent role as second messenger in many different plant processes, including sexual reproduction. However, there is much less knowledge about the involvement of Ca²⁺ during in vitro embryogenesis processes. In this work we performed a study of Ca²⁺ levels during the different stages of microspore embryogenesis in Brassica napus, with special attention to how Ca²⁺ can influence the occurrence of different embryogenic structures with different embryogenic potential. We also performed a pharmacological study to modulate Ca²⁺ homeostasis during different stages of the process, using a series of Ca²⁺-altering chemicals (BAPTA-AM, bepridil, chlorpromazine, cycl
