Megakaryocyte and polyploidization

Experimental Hematology, 2018
In mammals, platelets are produced in the blood by cytoplasmic fragmentation of megakaryocytes (MKs). Platelet production is thus dependent on both the MK number and size. During differentiation, MKs switch from a division by mitosis to polyploidization by endomitosis to increase their size. The endomitotic process includes several successive rounds of

Cytogenetics of Polyploids

1980
Following Winge’s classic paper on Polyploidy (1), there have been a large number of publications dealing with various aspects of the subject. However, this symposium is probably the first to bring together at one place and at one time so many different viewpoints and disciplines dealing with this subject.

Spontaneous polyploidization in cucumber

Theoretical and Applied Genetics, 2017
This is the first quantitative estimation of spontaneous polyploidy in cucumber and we detected 2.2% polyploids in a greenhouse study. We provide evidence that polyploidization is consistent with endoreduplication and is an on-going process during plant growth.

Physiology of Polyploids

1980
Polyploidy, a multiplication of the whole chromosomal complement, is a very widespread phenomenon in higher plants. Natural polyploids have been suggested to be more successful than their diploid progenitors under certain conditions. This success may be due to "balance hybridity," i.e., the combination of the advantage of hybridity together with the ...

Origins of Polyploids

1980
1. Polyploidy is a conspicuous feature of chromosomal evolution in higher plants. It is common in many genera, and numerous species are characterized by diploid and polyploid races. 2. Polyploid evolution is a process not an event. 3. Polyploid may involve somatic chromsome doubling or sexual functioning of cytologically non-reduced gametes.
