Normal microspore production after cell fusion in Brachiaria jubata (Gramineae)
Cytogenetic studies were carried out on 22 accessions of Brachiaria jubata from the Embrapa Beef Cattle Brachiaria collection. One accession was diploid (2n = 2x = 18) and the remaining 21 were tetraploid (2n = 4x = 36). Among five tetraploid accessions, a specific and constant pattern of cell fusion involving only two microsporocytes was recorded. Meiosis proceeded normally from prophase I to ...
متن کاملPollen and Pollen Tube Proteomics
Germinated pollen grains form pollen tubes that accomplish rapid polarized growth within female gametophytic tissues in order to deliver the sperm cell to the ovule. This process is essential for successful plant fertilization in vivo. Pollen tubes are considered to be an ideal model system to study tip growth. A more comprehensive understanding of proteins involved in pollen development, germi...
متن کاملA Contribution to the Pollen Morphology of Family Gramineae
Pollen morphology of 20 species belonging to the 14 genera of the family Gramineae has been investigated using light microscope and scanning microscope. It is a stenopalynous in nature. Pollen grains mostly spheroidal, monoporate rarely diporate, ±circular, pores small operculate, non-operculate, annulate or non-annulate. Tectum areolate to scabrate. On the basis of exine ornamentations 5 disti...
متن کاملAllergenic pollen and pollen allergy in Europe.
The allergenic content of the atmosphere varies according to climate, geography and vegetation. Data on the presence and prevalence of allergenic airborne pollens, obtained from both aerobiological studies and allergological investigations, make it possible to design pollen calendars with the approximate flowering period of the plants in the sampling area. In this way, even though pollen produc...
متن کاملPollen sporoplasts: dissolution of pollen walls.
4-Methylmorpholine N-oxide monohydrate (MMNO.H(2)O), a potent solvent for polysaccharides, is an effective vehicle for release of membrane-enclosed male gametophytes (sporoplasts) from spore walls. This release occurs in minutes when pollen (Lilium longiflorum Thunb.) is suspended in a melt of MMNO.H(2)O at 75 degrees C. Continued heating at 75 degrees C leads to distintegration of the exine ;s...
