The Slow Growth of Adventitious Roots in Tetraploid Hybrid Poplar (Populus simonii × P. nigra var. italica) May Be Caused by Endogenous Hormone-Mediated Meristem Shortening

Plants
Polyploidization produces abundant phenotypic variation. Little is currently known about adventitious root (AR) development variation due to polyploidization.

Impact of tetraploidization on morphophysiological leaf traits in the drought tolerant 'de Ramellet' tomato landrace

Photosynthetica
Tetraploidization was induced in the drought-tolerant tomato landrace 'de Ramellet' to evaluate its physiological and anatomical response under well-watered (WW) and water-deficient (WD) conditions. Under WW, tetraploid plants exhibited approximately 40%

Motile cilia structural and dynein preassembly factor genes are recessive in vegetative diploids.

A subset of diploids was examined for the occurrence of SNNC in 5 double heterozygous strains compared to single heterozygous controls. (A) swimming velocity, (B) beat frequency, and (C) cilia length for wild-type diploids and heterozygous diploids with ...

Growth and development of skeletal anomalies in diploid and triploid Atlantic salmon (Salmo salar) fed phosphorus-rich diets with fish meal and hydrolyzed fish protein.

PLoS ONE, 2018
Diploid and triploid Atlantic salmon, Salmo salar were fed high-protein, phosphorus-rich diets (56-60% protein; ca 18g phosphorus kg-1 diet) whilst being reared at low temperature from start-feeding until parr-smolt transformation. Performances of salmon

Other tetraploid species and conspecific diploids as sources of genetic variation for an autotetraploid

, 2010
• Premise of the study: Most plants are polyploid and have more than two copies of the genome. The evolutionary success of polyploids is often attributed to their potential to harbor increased genetic variation, but it is poorly understood how polyploids

Increasing Ca2+ accumulation in salt glands under salt stress increases stronger selective secretion of Na+ in Plumbago auriculata tetraploids

Frontiers in Plant Science
Under salt stress, recretohalophyte Plumbago auriculata tetraploids enhance salt tolerance by increasing selective secretion of Na+ compared with that in diploids, although the mechanism is unclear. Using non-invasive micro-test technology, the effect of

What drives the evolution of condition-dependent recombination in diploids? Some insights from simulation modelling

, 2017
While the evolutionary advantages of non-zero recombination rates have prompted diverse theoretical explanations, the evolution of essential recombination features remains underexplored.

Transcriptomic Analysis Reveals the Growth Regulatory Mechanisms in Diploid, Triploid, and Tetraploid Pacific Oyster (Crassostrea gigas)

Animals
Ploidy level exerts profound influences on the phenotypic and physiological traits of Crassostrea gigas. Compared to diploids, triploids exhibit desirable characteristics such as sterility, a faster growth rate, and improved meat quality.

Polyploid evolution: The ultimate way to grasp the nettle.

PLoS ONE, 2019
Polyploidy is one of the major forces of plant evolution and widespread mixed-ploidy species offer an opportunity to evaluate its significance. We therefore selected the cosmopolitan species Urtica dioica (stinging nettle), examined its cytogeography and
