Synaptonemal complex spreading in Allium cepa and A. fistulosum
Chromosoma, 1987The general features and fine structure of homologous chromosome alignment and pairing have been investigated in two species of Allium (A. fistulosum and A. cepa), which have similar karyotypes but very different patterns of chiasma distribution.

Introgression of Allium fistulosum into A. cepa mediated by A. roylei
Theoretical and Applied Genetics, 2000Introgression of Allium fistulosum into the genome of A. cepa using A. roylei as a bridging species was studied by means of genomic in situ hybridization (GISH). Here we demonstrate for the first time that A. fistulosum can be stably introgressed into A. cepa with a bridge-cross.

Experimental Hybrids between Allium fistulosum and A. roylei
Botanical Gazette, 1982Hybrids between Allium fistulosum (2n = 16), the Japanese bunching onion, and A. roylei (2n = 16), a wild species from the Himalayas, were vigorous and intermediate to the parents in leaf diameter, flower form, flower color, and time of flowering. Only one germinative seed was obtained from pollinating about 11,500 F1 flowers, and less than 30% of the ...

Exploring the structural basis for selenium/mercury antagonism in Allium fistulosum
Metallomics, 2012While continuing efforts are devoted to studying the mutually protective effect of mercury and selenium in mammals, few studies have investigated the mercury-selenium antagonism in plants. In this study, we report the metabolic fate of mercury and selenium in Allium fistulosum (green onion) after supplementation with sodium selenite and mercuric ...

Evidence for nuclear-cytoplasmic incompatibility between Allium fistulosum and A. cepa
Theoretical and Applied Genetics, 1995An F2 population (Allium fistulosum x A. cepa) of 20plants, 10 BC1,[(A. fistulosum x A. cepa) x A. cepa], and 50 BC2 plants, [(A. fistulosum x A. cepa) x A. cepa] x A. cepa were studied cytogenetically and characterized for four isozyme alleles plus various morphological characteristics. All of the progenies were in A.

Plant Science, 1994
Abstract Suspension cultures were initiated from friable nodule-forming calluses of five onion genotypes, two of Allium fistulosum L. and three of A. cepa L., and an interspecific A. fistulosum × A. cepa F 1 diploid hybrid. Eight liquid BDS (basal Dunstan and Short [2]) media supplemented with factorial combinations of plant growth ...

The age-related dynamics of chromosomal instability and germination capacity of welsh onion (Allium fistulosum L.) seeds have been studied under two different storage temperatures during six years after harvesting. Seeds that were kept at the room temperature (14???28 ????) during 6 years of storage have lost their germination capacity. The frequencies
