Gibberellins as a novel mutagen for inducing 2n gametes in plants [PDF]
Frontiers in Plant Science, 2023 The plant hormone gibberellin (GA) regulates many physiological processes, such as cell differentiation, cell elongation, seed germination, and the response to abiotic stress. Here, we found that injecting male flower buds with exogenous gibberellic acid

Genetic composition and heterozygosity of gibberellin-induced 2n gametes evaluated by SSR markers in Populus [PDF]
BMC Plant BiologyBackground The artificial induction of unreduced (2n) gametes, due to first division restitution (FDR) or second division restitution (SDR), is an important method to produce triploids in higher plants.

ClPS1 gene-mediated manipulation of 2n pollen formation enables the creation of triploid seedless watermelon [PDF]
Molecular HorticultureSeedless watermelons are increasingly dominating the consumer market due to their convenience and high quality. However, traditional triploid watermelon breeding faces challenges such as long breeding cycles and low survival rates of triploid F1 progeny,

Sorghum bicolor x S. halepense interspecific hybridization is influenced by the frequency of 2n gametes in S. bicolor. [PDF]
Sci Rep, 2019 Tetraploid johnsongrass [Sorghum halepense (L.) Pers.] is a sexually-compatible weedy relative of diploid sorghum [Sorghum bicolor (L.) Moench]. To determine the extent of interspecific hybridization between male sterile grain sorghum and johnsongrass ...

Unreduced Megagametophyte Production in Lemon Occurs via Three Meiotic Mechanisms, Predominantly Second-Division Restitution [PDF]
Frontiers in Plant Science, 2017 Unreduced (2n) gametes have played a pivotal role in polyploid plant evolution and are useful for sexual polyploid breeding in various species, particularly for developing new seedless citrus varieties.

Analysis of Meiotic Behavior and 2n Pollen Formation Frequency in Triploid Hybrids of Chinese Jujube [PDF]
PlantsThe Chinese jujube (Ziziphus jujuba Mill.), an economically significant fruit tree native to China, is valued for both fresh and dried uses. In plants, 2n gametes serve as the fundamental basis for creating a sexual polyploid germplasm.

The mechanism of tetraploidization in tree peony, and its implications for speciation and evolution of genus Paeonia L. [PDF]
Frontiers in Plant ScienceIntroductionPolyploidization is not only an important driving force for plant speciation and evolution, but also an effective approach for plant domestication and improvement. Polyploid taxa are quite common in Paeonia section Paeonia (herbaceous peonies)

Exploiting Unreduced Gametes for Improving Ornamental Plants
Frontiers in Plant Science, 2022 The formation of gametes with somatic chromosome number or unreduced gametes (2n gametes) is an important process involved in the origin of polyploid plants in nature. Unreduced gametes are the result of meiotic mutations occurring during micro- and mega-
