The Occurrence of Starch and Erythrodextrin in Maize and Their Segregation in the Pollen of Hybrids.

Inflated Sporopollenin Exine Capsules Obtained from Thin-Walled Pollen

Sporopollenin is a physically robust and chemically resilient biopolymer that comprises the outermost layer of pollen walls and is the first line of defense against harsh environmental conditions. The unique physicochemical properties of sporopollenin increasingly motivate the extraction of sporopollenin exine capsules (SECs) from pollen walls as a renewable source of organic microcapsules for ...

Automatic Pollen Grain and Exine Segmentation from Microscope Images

In this article, we propose an automatic method for the segmentation of pollen grains from microscope images, followed by the automatic segmentation of their exine. The objective of exine segmentation is to separate the pollen grain in two regions of interest: exine and inner part. A coarse-to-fine approach ensures a smooth and accurate segmentation of both structures. As a rough stage, grain s...

Chromosome segregation from cell hybrids

We searched for evidence of aberrant movement or position of segregant set chromosomes in Cbanded and G-11 -banded early-phase hamstermouse and hamster-human cell hybrids that had been prepared with minimal disruption. No evidence was obtained for an increased frequency of multipolar mitosis, delayed or precocious metaphase congression or anaphase segregation, or for exclusion of chromosomes fr...
