Autotetraploidization Gives Rise to Differential Gene Expression in Response to Saline Stress in Rice

Plants, 2022
Plant polyploidization represents an effective means for plants to perpetuate their adaptive advantage in the face of environmental variation. Numerous studies have identified differential responsiveness to environmental cues between polyploids and their

Analysis of Population Structure in Autotetraploid Species [PDF]

Genetics, 1998
Abstract Population structure parameters commonly used for diploid species are reexamined for the particular case of tetrasomic inheritance (autotetraploid species). Recurrence equations that describe the evolution of identity probabilities for neutral genes in an “island model” of population structure are derived assuming tetrasomic ...

DNA Methylome and LncRNAome Analysis Provide Insights Into Mechanisms of Genome-Dosage Effects in Autotetraploid Cassava

Frontiers in Plant Science, 2022
Whole genome duplication (WGD) increases the dosage of all coding and non-coding genes, yet the molecular implications of genome-dosage effects remain elusive.

LINKAGE IN AUTOTETRAPLOID MAIZE [PDF]

Genetics, 1962
bivalent and, since four potential gametes result from each meiosis, these strands pass to different gametes and may, genetically, be dealt with separately. The only concern, therefore, is with the proportioris of each type of strand resulting from crossing-over and their possible combinations in the zygotes.

A novel statistical method for assessing SSR variation in autotetraploid alfalfa (Medicago sativa L.)

Genetics and Molecular Biology, 2007
The level of variation of simple sequence repeat (SSR) markers in cultivated alfalfa from American, Australian and Chinese sources was evaluated using a novel autotetraploid statistical method to calculate the effective number of alleles, the allele ...

Genome-wide analysis of DNA polymorphisms, the methylome and transcriptome revealed that multiple factors are associated with low pollen fertility in autotetraploid rice. [PDF]

PLoS ONE, 2018
Autotetraploid rice is a useful germplasm with high biomass production; however, low fertility is the main barrier in commercial utilization. In our previous study, differential expression of meiosis-related miRNAs was found to be involved in the pollen ...

Influence of the Rootstock and the Ploidy Level of the Scion and the Rootstock on Sweet Orange (Citrus sinensis) Peel Essential Oil Yield, Composition and Aromatic Properties

Agriculture, 2022
Rootstock is widely used for the cultivation of citrus fruits because it brings resistance or tolerance to diseases or environmental constrains and modulates the fruit quality. Polyploidization is a widespread improvement strategy in citrus.

Agro-Morphological and Cytogenetic Characterization of Colchicine-Induced Tetraploid Plants of Polemonium caeruleum L. (Polemoniaceae)

Plants, 2022
Polemonium caeruleum L. (Polemoniaceae) is a valuable medicinal herb with a wide spectrum of biological activities. Under natural conditions, the productivity of this species is rather low.

Pervasive interactions of Sa and Sb loci cause high pollen sterility and abrupt changes in gene expression during meiosis that could be overcome by double neutral genes in autotetraploid rice

Rice, 2017
Background Intersubspecific autotetraploid rice hybrids possess high hybrid vigor; however, low pollen fertility is a critical hindrance in its commercial utilization.

A Comparative Analysis of Major Cell Wall Components and Associated Gene Expression in Autotetraploid and Its Donor Diploid Rice (Oryza sativa L.) under Blast and Salt Stress Conditions

Plants, 2023
Whole-genome duplication is a significant evolutionary mechanism in plants, with polyploid plants often displaying larger organs and enhanced adaptability to unfavorable conditions compared to their diploid counterparts.
