Genetic variability of anther donor versus spontaneous doubled haploid descendents and colchicine induced doubled haploid sweet pepper (Capsicum annuum L.) lines [PDF]

, 2001
Haploid (n) and doubled haploid (DH) plants were developed in anther culture of sweet pepper (Capsicum annuum L.). Regenerants were analyzed by flow cytometry for haploid (n = 12) and spontaneous doubled haploid (2n = 24) genomes.

Karyotype, ploidy, and gene dosage [PDF]

WormBook, 2005
The normal karyotype of Caenorhabditis elegans, with its five pairs of autosomes and single pair of X chromosomes, is described. General features of chromosomes and global differences between different chromosomal regions are discussed. Abnormal karyotypes, including duplications, deficiencies, inversions, translocations and chromosome fusions are ...

Neuroblastoma in Infants: Long‐Term Survival From INES Protocols A SIOPEN Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Objectives Neuroblastoma is the most common extracranial solid tumor in infants, with a possibility of spontaneous regression even in disseminated disease. Despite an overall good prognosis, relapse can worsen the outcome for some patients. A long‐term analysis is crucial to identify subgroups of patients with poorer prognosis, assessing the ...

Chloroplast genome diversity and phylogenetic insights of Saccharum spontaneum across Southeast Asia

PLANTS, PEOPLE, PLANET, EarlyView.
Climate change and threats to global food security have increased the urgency of conserving genetic resources in key crops like sugarcane. In this study, we analyzed the chloroplast genomes of wild sugarcane to assess their genetic diversity and population structure. We found a high level of diversity, regardless of geographic location, and patterns of

Molecular and morphological phylogenetics of the digitate-tubered clade within subtribe Orchidinae s.s. (Orchidaceae: Orchideae) [PDF]

, 2018
The digitate-tubered clade (Dactylorhiza s.l. plus Gymnadenia s.l.) within subtribe Orchidinae is an important element of the North-temperate orchid flora and has become a model system for studying the genetic and epigenetic consequences of organism-wide

Conservation challenges and opportunities for native apple (Malus) species in Canada

PLANTS, PEOPLE, PLANET, EarlyView.
Apple, one of the world's most widely cultivated and economically important fruit crops, has two wild relatives native to Canada. In this review, we describe the importance of these native apple species to Indigenous heritage and the current threats the species faces due to pests, diseases, and habitat loss.

Gene expression in Leishmania is regulated predominantly by gene dosage [PDF]

, 2017
Leishmania tropica, a unicellular eukaryotic parasite present in North and East Africa, the Middle East, and the Indian subcontinent, has been linked to large outbreaks of cutaneous leishmaniasis in displaced populations in Iraq, Jordan, and Syria. Here,
