A New Way of Rice Breeding: Polyploid Rice Breeding

Plants, 2021
Polyploid rice, first discovered by Japanese scientist Eiiti Nakamori in 1933, has a history of nearly 90 years. In the following years, polyploid rice studies have mainly focused on innovations in breeding theory, induction technology and the creation ...

The polyploid continuum and the landscape of polyploid genomic variation

American Journal of Botany
Abstract Polyploid research has traditionally distinguished between autopolyploids and allopolyploids on the basis of evolutionary origins, modes of inheritance, or chromosomal pairing behavior during meiosis. It has long been recognized, however, that a binary classification does not accurately reflect the complexity and diversity ...

Relevance of unilateral and bilateral sexual polyploidization in relation to intergenomic recombination and introgression in Lilium species hybrids

, 2010
Sexual polyploids were induced in diploid (2n = 2x = 24) interspecific F1 hybrids of Longiflorum × Asiatic (LA) and Oriental × Asiatic (OA) Lilium hybrids by backcrossing to Asiatic (AA) parents as well as by sib-mating of the F1 LA hybrids.

Hox genes reveal genomic DNA variation in tetraploid hybrids derived from Carassius auratus red var. (female) × Megalobrama amblycephala (male)

BMC Genetics, 2017
Background Allotetraploid F1 hybrids (4nF1) (AABB, 4n = 148) were generated from the distant hybridization of Carassius auratus red var. (RCC) (AA, 2n = 100) (♀) × Megalobrama amblycephala (BSB) (BB, 2n = 48) (♂).

Chromosome Stability of Synthetic-Natural Wheat Hybrids

Frontiers in Plant Science, 2021
Primary allopolyploids are not only ideal materials to study species evolution, but also important bridges in incorporating genetic diversity of wild species into crops.

Leaf micromorphology and genetic diversity analysis of Iranian Hordeum species using ISSR and SCoT markers

Nordic Journal of Botany, EarlyView.
The genus Hordeum (Poaceae), of the tribe Triticeae, comprises approximately 32 species with substantial potential for barley improvement. Hordeum vulgare is an economically important cereal widely cultivated across diverse environments, from the Arctic to desert and humid regions.

Polyploidization of transplanted cardiac myocytes [PDF]

, 1988
Pieces of cardiac ventricular tissue of late embryonic or 1-day postnatal rats, implanted beneath the kidney capsule of adult syngeneic hosts, formed viable, beating transplants. these transplants were investigated over a 40-day postoperative course.

MicroRNAs as potential architects of immune dysregulation and megakaryocytic failure in immune thrombocytopenia

British Journal of Haematology, EarlyView.
Summary Immune thrombocytopenia (ITP) is a complex autoimmune disorder characterized by accelerated destruction of peripheral platelets and impaired megakaryopoiesis. While the cellular effectors, dysregulated T cells, hyperactive B cells and phagocytic macrophages are well characterized, the upstream epigenetic mechanisms orchestrating this ...

Mechanisms of Thrombocytosis in Iron‐Deficiency Anemia

European Journal of Haematology, EarlyView.
ABSTRACT Iron‐deficiency anemia is frequently accompanied by reactive thrombocytosis, yet the mechanisms underlying this association remain incompletely understood. Beyond impaired erythropoiesis, iron availability has emerged as an active regulator of hematopoietic lineage decisions.

A CORRECTION HAS BEEN PUBLISHEDOptimized tetraploidization strategies in tissue culture for Lolium, Festuca, and Festulolium

Biologia Plantarum
In plant breeding, polyploidization is an established technique to obtain superior phenotypic characteristics. In seed propagated agricultural crops, seed treatments with antimitotic agents are often used to obtain chromosome doubling. Here, we developed
