Harnessing the developmental potential of nucellar cells: Barriers and opportunities [PDF]

, 2004
Angiosperm nucellar cells can either use or avoid meiosis in vivo, depending on the developmental context. This unique ability contrasts with the conditions required in vitro, either for a reconstituted oocyte to avoid meiosis and produce clones by ...

Garlic (Allium sativum L.) fertility: transcriptome and proteome analyses provide insight into flower and pollen development

Frontiers in Plant Science, 2015
Commercial cultivars of garlic, a popular condiment, are sterile, making genetic studies and breeding of this plant challenging. However, recent fertility restoration has enabled advanced physiological and genetic research and hybridization in this ...

ROS homeostasis and cell wall biosynthesis pathway are involved in female inflorescence development of birch (Betula platyphylla)

BMC Plant Biology
Background Female inflorescence development from megasporogenesis to gametogenesis, and mature female gametophyte (FG), is a complex and important event in plant sexual reproduction. However, how this essential developmental process is regulated in birch
