A senescence-like cell-cycle arrest occurs during megakaryocytic maturation: implications for physiological and pathological megakaryocytic proliferation. [PDF]

PLoS Biology, 2010
Thrombopoietin (TPO) via signaling through its cognate receptor MPL is a key cytokine involved in the regulation of megakaryocyte differentiation leading to platelet production. Mature megakaryocytes are polyploid cells that have arrested DNA replication

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.

Induction of synthetic polyploids of Porang (Amorphophallus muelerri blume) and assessment of its genetic variability using morphological data and RAPD molecular marker [PDF]

, 2023
This study uses morphological characteristics and RAPD markers to evaluate the polyploidization of synthetic porang. Seeds of triploid porang (2n=2x=26) were soaked in the different colchicine concentrations for 24 hours.

Polyploid induction of Allium ascalonicum L. by colchicine

Biodiversitas Journal of Biological Diversity, 1970
The low production rate of shallot (Allium ascalonicum L.) in Indonesia could be caused by rarely excellent cultivars.Colchicine was one of the mutation agents frequently used in plant breeding in order to get polyploidy of cultivars. The aim of this research was to find out the differentiation of morphometric evidences and ploidy of shallot ...

Speciation with gene flow

PLANTS, PEOPLE, PLANET, EarlyView.
Biodiversity is threatened by human activities, with extinction debt accumulating rapidly. Many of these activities change the connectivity of populations, fragmenting existing population systems or bringing previously isolated populations or species into contact.

Induction of polyploid Malus prunifolia and analysis of its salt tolerance

Tree Physiology, 2022
Abstract The apple rootstock Malus prunifolia (Willd.) Borkh. is widely used for apple production. Because polyploid plants are often more tolerant to abiotic stress than diploids, we wondered whether polyploidy induction in M. prunifolia might improve its stress tolerance, particularly to high salinity.

A novel and tissue-culture-free polyploidization method based on adventitious bud formation of Populus

Industrial Crops and Products
Polyploid breeding is one of the important approaches for developing new varieties and driving forest germplasm innovation. Existing somatic chromosome doubling methods heavily rely on the sterile requirement of tissue culture and the establishment of ...

Traversing the effects of ploidy changes in different Eragrostis curvula genotypes through high-throughput RNA sequencing. [PDF]

Plant Genome
Abstract Polyploidization has played a key role in plant genome evolution. Eragrostis curvula (Schrad.) Ness, a perennial forage grass species of the Poaceae family, is an excellent model for investigating genome duplication due to its natural variation in ploidy levels.

Past, present and future of local crop evolution

PLANTS, PEOPLE, PLANET, EarlyView.
Promoting agrobiodiversity is a promising strategy for mitigating the negative effects of climate change on global food security. We highlight the central role evolutionary processes play in harnessing the potential of local crops by integrating genomics, archaeology, ethnobotany and traditional ecological knowledge (TEK).
