1. A new meiotic abnormality in Zea mays: multiple spindles associated with abnormal cytokinesis in both divisions

Author:

Subject:
Zea mays; chromosomes; pollen; inbred lines; abnormal development; prophase; meiosis; metaphase
Abstract:
... We report here a new meiotic abnormality recorded in one plant of an inbred line of Zea mays. After an apparently normal prophase I, chromosomes did not congregate in a single metaphase plate. Bivalents remained scattered in the cytoplasm, giving rise to several spindles. Despite the occurrence of multiple spindles, meiosis I proceeded normally, forming a varied number of nuclei at telophase I. Th ...

random amplified polymorphic DNA technique; microsatellite repeats; loci; Prunus persica; chromosome mapping; linkage (genetics); plant morphology; genetic markers
Abstract:
... A linkage map was obtained using a BC1 progeny (Prunus persica x (P. persica x P. ferganensis)). The map is composed of 109 loci (74 RFLPs, 17 SSRs, 16 RAPDs, and two morphological traits) distributed in 10 linkage groups. Loci, segregating in five different ratios, were integrated in the map with JoinMap 2.0 software. The map covers 521 cM of the peach genome. The average distance between adjacen ...

Here we report on the characterisation of microsatellite markers and on their use for the determination of genetic identities and the assessment of genetic variability among accessions from a germplasm collection of hop. Thirty-two polymorphic alleles were found in the ...

Abstract:
... Recent research on the phenomena and manifestations of bereavement, as represented in this ABS special issue, has contributed to the understanding of two central, long-standing questions: How do bereaved persons cope with their loss? What is the nature and meaning of normal versus complicated grief? In this review, these themes are linked to historical trends, evaluation is made of current knowled ...

We investigated collinearity of marker order by comparing two contrasting regions of the Brassica oleracea genome with homologous regions of A. thaliana. Although there is widespread replication of marker loci in bot ...

Abstract:
... The effect of ecdysone on the puffing activity of the polytene chromosomes of Ceratitis capitata has been studied in organ cultures of late-larval salivary glands. Culture of glands from 120-h-old larvae (puff stage 1) in the presence of ecdysone resulted in the initiation of the late-larval puffing cycle that is normally observed in 145-h-old larvae (puff stage 4). During a 7-h period in the pres ...

Best Management Practices (BMPs) can be used to reduce these pollutants, but understanding the most effective practices is very difficult. Watershed models are the most cost-effective tools to aid in the decision-making process of selecting the BMP that is most effective in reducing t ...

Subject:
death and dying; probability
Abstract:
... Traditional bereavement theories emphasize that it is crucial to work through the emotional meanings of a loss and that the failure to do so typically results in delayed grief symptoms. This article reports data examining these assumptions prospectively across the first 5 years of bereavement. Based on previous validity data, elevated symptoms were defined in terms of 6-month median scores for eac ...

Abstract:
... The long arm of chromosome 4D in wheat (Triticum aestivum L.) has been shown in previous studies to harbor genes of agronomic importance. A major dominant gene conferring Aluminum (Al) tolerance (Alt2 in 'Chinese Spring' and Alt(BH) in 'BH 1146'), and the Kna1 locus controlling the K(+)/Na(+) discrimination in saline environments have been mapped to this chromosome arm. However, accurate informati ...

Abstract:
... Monosomic alien addition lines (MAALs) are useful for assigning linkage groups to chromosomes. We examined whether the chromosomal rearrangements following the introduction of a single onion (Allium cepa) chromosome into the Allium fistulosum genome were produced by homeologous crossing over or by a nonreciprocal conversion event. Among the monosomic lines available, 17 were studied by fluorescent ...
