Evolutionary regularities of development of somatic polyploidy in salivary glands of gastropod mollusks: V. Subclasses Opisthobranchia and Pulmonata
TLDR
The high degree of obligatory polyploidization revealed in salivary gland cells of the opisthobranchian and pulmonate mollusks is considered as a peculiar cytological arogenesis as compared with allogenic, facultative, and slight manifestations ofpolyploidy in prosobranchian gastropod mollUSks.

The morphofunctional characterization and ploidy levels of the digestive gland cells in prosobranch gastropod mollusks (Prosobranchia: Gastropoda) with special reference to somatic polyploidy
TLDR
Cases of somatic polyploidy in basophilic cells are considered as adaptive modifications of histogenesis associated with the peculiarities of the environment (intensified metabolism in osmotically tolerant Littorina and Lottia species), the duration of ontogenesis, and a specific diet. Expand
Endopolyploidy as a morphogenetic factor of development
TLDR
Endopolyploidy is an adaptive morphogenetic factor, but its concrete role may differ in different tissues and organisms depending on cell specialization and histogenetic particularities. Expand
Morphological Variability and Levels of Nuclear Ploidy in Neurons of the Central Nervous System of Bivalves Relative to the Problem of Somatic Polyploidy
TLDR
Apparently, the polyploidy, as an evolutionary strategy of neuron growth, had no anatomical prerequisites in bivalves, which is similar to CNS oligomerization in higher gastropods, as they are devoid of any functional adaptive sense. Expand
