Moldovan line MHI the source for obtaining a large number of haploid plants in maize [PDF]

open access: yesSelekcija i Semenarstvo, 2004
The hypothesis of the shortening the cycle of selection was tested in maize, by using the MHI line (Moldovan Haploid Inducer) for inducing haploids in five F1 elite single crosses, made for the purposes of further inbreeding and gaining new elite inbred ...

Brood parasitism reduces but does not prevent Bombus terrestris reproductive success

open access: yesInsect Science, EarlyView.
Graphical depiction of the colony splitting process. Throughout figures in this paper, results pertaining to host success are represented in blue, and cuckoo success is represented in red. Abstract Cuckoo bumblebees are obligate brood parasites that must invade a colony of their host bumblebee species in order to reproduce.

The use of deidentified organ donor testes for research

open access: yesAndrology, EarlyView.
Abstract Our knowledge of testis development and function mainly comes from research using mammalian model organisms, primarily the mouse. However, there are integral differences between men and other mammalian species regarding cellular composition and expression profiles during fetal and post‐natal testis development and in the mature testis ...

The effect of phytosulfokine alpha on haploid embryogenesis and gene expression of Brassica napus microspore cultures

open access: yesFrontiers in Plant Science
Microspore embryogenesis (ME) is the most powerful tool for creating homozygous lines in plant breeding and molecular biology research. It is still based mainly on the reprogramming of microspores by temperature, osmotic and/or nutrient stress.

Testis‐Enriched F‐Box Protein FBXO39 Is Important for Spermiogenesis and Male Fertility in Mice

open access: yesAndrology, EarlyView.
ABSTRACT Background The SCF (Skp–Cullin–F‐box) complex is a major class of E3 ubiquitin ligases. F‐box proteins constitute the SCF complex and play a critical role in recognizing substrates for ubiquitination. In mice, several F‐box proteins, including FBXO36 and FBXO39, are predominantly expressed in testes.

Sperm Head–Tail Coupling Apparatus Diversity and Common Themes Among Species

open access: yesAndrology, EarlyView.
ABSTRACT Background A stable connection between the sperm head (containing the nucleus and acrosome) and tail (containing the axoneme, mitochondrial sheath, and periaxonemal structures) is critical for fertility. This connection is mediated by a series of nuclear, cytoplasmic, and centriole components that make up the head–tail coupling apparatus (HTCA)

Anatomical and Histological Structures of the Male Reproductive System of Chalcophora mariana (Linnaeus, 1758) (Coleoptera: Buprestidae): Light and Scanning Electron Microscopy Study

open access: yesActa Zoologica, EarlyView.
ABSTRACT This study presents the first detailed morphological analysis of the male reproductive system of Chalcophora mariana (Linnaeus, 1758) using stereo microscopy, light microscopy, and scanning electron microscopy. The male reproductive system of C.

Haploid identification in maize

open access: yesFrontiers in Plant Science
Doubled haploid (DH) line production throughin vivomaternal haploid induction is widely adopted in maize breeding programs. The established protocol for DH production includes four steps namelyin vivomaternal haploid induction, haploid identification, genome doubling of haploid, and self-fertilization of doubled haploids.

Anatomical and Histological Descriptions of the Male Reproductive System of the Alfalfa Weevil of Hypera postica (Gyllenhal, 1813) (Coleoptera: Curculionidae) Using Light and Scanning Electron Microscopies

open access: yesActa Zoologica, EarlyView.
ABSTRACT Features of the reproductive organs, such as the number of testicular follicles, testis colour and the morphology of the glands, can be used as systematic characters. For this purpose, this paper was the first description of the male reproductive system anatomy and histology of Hypera postica (Gyllenhal, 1813) (Coleoptera: Curculionidae), a ...

Minimal residual disease in diffuse large B‐cell lymphoma after first‐line therapy: Defining the continuum from metabolic remission to molecular clearance

open access: yesBritish Journal of Haematology, EarlyView.
Summary Response assessment in diffuse large B‐cell lymphoma (DLBCL) has traditionally relied on anatomical and metabolic imaging, with fluorodeoxyglucose positron emission tomography (FDG‐PET)–defined complete metabolic remission representing the principal end‐point of first‐line therapy. However, growing evidence indicates that metabolic control does
