The low molecular weight fraction of compounds released from immature wheat pistils supports barley pollen embryogenesis [PDF]
Pollen embryogenesis provides a useful means of generating haploid plants for plant breeding and basic research. Although it is well established that the efficacy of the process can be enhanced by the provision of immature pistils as a nurse tissue, the ...

Early evolutionary history of the seed
ABSTRACT The seed is an essential stage in the life history of gymnospermous and angiospermous plants, facilitating both their survival and dispersal. We reappraise knowledge of the evolutionary history of the gymnospermous seed, from its origin in the late Devonian through to the well‐known end‐Permian extinctions – an interval encompassing the ...

Microspore embryogenesis in vitro: the role of stresses
Gametic embryogenesis is one form of totipotency of plant cells, in which either male or female gametes are induced to form embryoids (sporophytes). Regeneration of haploid plants from embryoids and subsequent chromosome duplication result in doubled ...

Rice panicle temperature and crop microclimate in stressful thermal environments: toward a model of spikelet sterility [PDF]
Rice inflorescences are sensitive to chilling and heat, resulting in spikelet sterility. It is not the air temperature itself, however, that causes the stress but the temperature of the sensitive tissues during specific developmental stages.

A barley PHD finger transcription factor that confers male sterility by affecting tapetal development [PDF]
Controlling pollen development is of major commercial importance in generating hybrid crops and selective breeding, but characterized genes for male sterility in crops are rare, with no current examples in barley.

Electron microscopy‐based three‐dimensional subcellular imaging of plant male gametophyte
The Aquilos2 Cryo‐FIB workflows provide practical routes for cryo‐electron tomography and volume imaging in plant structural biology. ABSTRACT Understanding cellular events in three dimensions (3D) is of great importance for the annotation and illustration of biological processes in a contextual way. Imaging techniques based on electron microscopy (EM),
