Microsporogenesis, microgametogenesis and pollen morphology of Passiflora spp. (Passifloraceae) [PDF]
Microsporogenesis, microgametogenesis and pollen morphology of six species of genus Passiflora L. belonging to three subgenera (Passiflora, Dysosmia, Decaloba) were studied with light and scanning microscopy; P. caerulea was also examined with transmission microscopy.

Scanning and transmission electron microscopy ofEimeria maximamicrogametogenesis
SUMMARYThe structure and development of microgametocytes ofEimeria maximafrom chicks killed during the 6th day of infection were examined using transmission and scanning electron microscopy. Initially, nucleoli disappear and the surface of the microgametocyte invaginates.

Arabidopsis COG Complex Subunits COG3 and COG8 Modulate Golgi Morphology, Vesicle Trafficking Homeostasis and Are Essential for Pollen Tube Growth. [PDF]
Spatially and temporally regulated membrane trafficking events incorporate membrane and cell wall materials into the pollen tube apex and are believed to underlie the rapid pollen tube growth.

Phenological phases of flowering in hop (Humulus lupulus L.) and their correspondence with microsporogenesis and microgametogenesis [PDF]
[EN] Hop (Humulus Lupulus L.) suffered, as many other crops, a shrinkage of its intraspecific agrobiodiversity. Biotechnological methods of breeding would offer new opportunities to produce improved varieties with interesting phytochemical profiles and adaptable to the challenging conditions of climate change. Doubled haploid (DH) technology could be a

Very little was known about the family of six myosins in malaria‐causing parasites, except for a role of one in motility. We show here that myosins have a diverse pattern of expression and subcellular location through the parasite life cycle in both the mammalian host and mosquito vector.

Pollen Development and Stainability in Vicia faba L. and Lupinus angustifolius L.
Commercially, leguminous crops (Fabaceae) are the second most important group of cultivated plants, just after grasses (Poaceae). This study focuses on the analysis of pollen development and stainability in two species belonging to the Fabaceae family ...
