Restricted Distribution of Tetraploid Cells in Mouse Tetraploid ↔ Diploid Chimaeras

Developmental Biology, 1995
Tetraploid mouse embryos were produced by electrofusion at the 2-cell stage, cultured overnight, and aggregated with normal diploid embryos to produce tetraploiddiploid (4n2n) chimaeric conceptuses. At 7 1/2 days the 4n2n chimaeras were usually smaller and developmentally retarded compared to control diploiddiploid chimaeras.

Effect of polyploidization on morphology in two apple (Malus × domestica) genotypes

Horticultural Science, 2017
Because polyploidy often results in enhancement of desirable properties, artificial genome doubling is commonly used in agri- and horticultural crop breeding programs. In this study genome doubling was induced in two apple genotypes.

Discovery and characterization of sweetpotato’s closest tetraploid [PDF]

, 2022
The origin of sweetpotato, a hexaploid species, is poorly understood, partly because the identity of its tetraploid progenitor remains unknown. In this study, we identify, describe and characterize a new species of Ipomoea that is sweetpotato's closest ...

Assessing Ploidy Level Analysis and Single Pollen Genotyping of Diploid and Euploid Citrus Genotypes by Fluorescence-Activated Cell Sorting and Whole-Genome Amplification

Frontiers in Plant Science, 2019
Flow cytometry is widely used to determine genome size and ploidy level in plants. This technique, when coupled with fluorescence-activated cell sorting (FACS), whole genome amplification and genotyping (WGA), opens up new opportunities for genetic ...

A comparative study on rooting of in vitro regenerated shoots in haploid, diploid and tetraploid purple coneflower (Echinacea purpurea L.)

Biotechnology & Biotechnological Equipment, 2016
Haploid, diploid and tetraploid shoots of Echinacea purpurea L. sharing the same genome were cultured in medium and their rooting response to the composition of the culture medium was investigated.

Chromosome doubling can increase heat tolerance in Lonicera japonica as indicated by chlorophyll fluorescence imaging

Biologia Plantarum, 2011
Imaging fluorometry was applied to investigate the tolerance of Japanese honeysuckle (Lonicera japonica Thunb.) of different ploidy levels to heat stress. Seedlings of L. japonica, the diploid cv. Damaohua and the tetraploid cv.

Phenotypic characterization, plant growth and development, genome methylation, and mineral elements composition of neotetraploid lettuce (Lactuca sativa L.)

Frontiers in Plant Science, 2023
Stable neotetraploid lines of lettuce (Lactuca sativa L.) were produced from three phenotypically distinct cultivars (Annapolis, Eruption, Merlot) and an advanced breeding line (SM13-L2) using colchicine treatment of seeds or young seedlings. When tested

Effects of methyl jasmonate on the growth and triterpenoid production of diploid and tetraploid Centella asiatica (L.) Urb. hairy root cultures

Scientific Reports, 2019
In this study, the effects of methyl jasmonate (MeJA) on the phytomass and triterpenoid production of diploid and tetraploid Centella asiatica hairy roots were investigated.

Asymmetric clustering of centrosomes defines the early evolution of tetraploid cells

bioRxiv, 2019
Tetraploidy has long been of interest to both cell and cancer biologists, partly because of its documented role in tumorigenesis. A common model proposes that the extra centrosomes that are typically acquired during tetraploidization are responsible for ...

Drought Stress Mediated Changes in Food Crops: Mechanisms and Remediation Strategies

Advanced Science, EarlyView.
This work presents a multi‐scale framework for flavonoid‐mediated drought tolerance in staple food crops, integrating ROS redox regulation, antioxidant defense, rhizosphere microbial interactions, and sustainable agronomic practices. This interdisciplinary model provides core insights to develop climate‐resilient cropping systems and enhance global ...
