Segmenting 20 Types of Pollen Grains for the Cretan Pollen Dataset v1 (CPD-1)
Pollen analysis and the classification of several pollen species is an important task in melissopalynology. The development of machine learning or deep learning based classification models depends on available datasets of pollen grains from various plant

Palaeolimnology of Lake Sapanca and identification of historic earthquake signals, Northern Anatolian Fault Zone (Turkey) [PDF]
Lake Sapanca is located on a strand of the Northern Anatolian Fault Zone (NAFZ, Turkey), where a series of strong earthquakes (Ms >6.0) have occurred over the past hundred years. Identifying prehistoric earthquakes in and around Lake Sapanca is key to a

Preliminary studies on mustard taxonomy based on pollen morphology
Pollen grains of 17 mustard subspecies were examined under scanning electron microscope. The result showed that the pollen shapes were nearly spherical, or spheroidal, or super-spheroidal from the equatorial view, depending on cultivars of mustard.

Disturbances in microsporogenesis and pollen grain development in Gagea lutea (L.) Ker. Gaw.
The meiotic division of microsporocytes and pollen grain development in Gagea lutea (L.) Ker.-Gaw. (Liliaceae) with fluorescence microscope (excitation light 400 nm) was observed after squashing the anthers in DAPI solution (fluorochrom dying DNA). Up to

Messenger RNas : their utilization and degradation during pollen germination and tube growth
During pollen germination and tube growth at least 230 new proteins are synthesized, as determined by 35S-methionime labeling and two dimensional gel electrophoretic analysis of the labeled proteins.

Pollen grains for oral vaccination [PDF]
Oral vaccination can offer a painless and convenient method of vaccination. Furthermore, in addition to systemic immunity it has potential to stimulate mucosal immunity through antigen-processing by the gut-associated lymphoid tissues. In this study we propose the concept that pollen grains can be engineered for use as a simple modular system for oral ...
