In situ Parthenogenetic Doubled Haploid Production in Melon “Piel de Sapo” for Breeding Purposes

Frontiers in Plant Science, 2020
Doubled haploids in cucurbit species are produced through in situ parthenogenesis via pollination with irradiated pollen for further use as parental lines for hybrid F1 production. In this study, seven genotypes of melon “Piel de Sapo” were appraised for

Approaches to Superefficient Yeast Transformations: DNA Phase Separation, Cell Growth State and Systematic Experimental Design

Yeast, EarlyView.
Yeast transformations are mechanistically poorly understood and could be made orders of magnitude more efficient by three approaches. (1) Investigate mechanisms of DNA uptake including DNA phase separation. (2) Account for growth state. (3) Use systematic statistical design of experiments to test combinations of factors that enhance transformation ...

Russian wheat aphid: a model for genomic plasticity and a challenge to breeders

Insect Science, EarlyView.
Invasive foundress finds suitable habitat and reproduces through pathogenesis. Wingless females produce life offspring quickly, which leads to high population densities. High population densities result in competition, which may induce epigenetic changes and wing development for dispersal.

CENH3: AN EMERGING PLAYER IN HAPLOID INDUCTION TECHNOLOGY

Frontiers in Plant Science, 2016
True-breeding lines are required for the development and production of crop varieties. In a classical breeding approach these lines are obtained through inbreeding, and often 7-9 generations of inbreeding is performed to achieve the desired level of ...

Male Mice Heterozygous for Protamine 1 and Protamine 2 Are Infertile, Displaying Sperm Damage and Retention of Protamine 2 Precursors, Transition Proteins, and Histones

Andrology, EarlyView.
ABSTRACT Background During spermiogenesis, protamines (PRMs) replace histones to hypercondense and protect sperm DNA. Rodents and primates express two PRMs (PRM1 and PRM2). Alterations of species‐specific PRM ratios are associated with sub‐ or infertility in mice and humans.

A CCNA1 Missense Variant Associated With Chromatid Non‐Disjunction in Abnormal‐Headed Sperm and Male Infertility

Andrology, EarlyView.
ABSTRACT Background Macrozoospermia is a rare form of teratozoospermia characterized by tetraploids, large‐headed spermatozoa with multiple flagella, usually caused by bi‐allelic AURKC mutations. The etiology of atypical phenotypes with a lower proportion of large headed spermatozoa and single flagella however often remains unresolved.

On the issue of producing doubled haploids of table beet (Beta vulgaris L. var. conditiva Alef.) (a review)

Труды по прикладной ботанике, генетике и селекции
Currently, hybrid table beet seeds make up a significant part of the seeds sold in the world due to their high synchrony, root uniformity, and the effect of heterosis. Heterosis breeding of table beet in Russia is developed insufficiently.
