摘要

Trifluralin is a herbicide capable of interfering in mitotic cell division due to either microtubule depolymerization or alteration in the concentration of calcium ions within the cell. The aim of this study was to investigate the effects of trifluralin in Allium cepa meristematic cells, evaluating the induction mechanisms of the chromosomal and nuclear aberrations. In this study, A. cepa root tips were submitted for 24 h treatment to several concentrations of this herbicide and 48 h recovery post-treatment. The results showed that some concentrations of trifluralin can lead to a mitotic index inhibition, besides inducing chromosomal and nuclear alterations throughout the mitotic cycle. Some of the alterations found seem to be resulting from the herbicide action in different phases and in more than one consecutive cell cycle. (C) 2009 Elsevier Inc. All rights reserved.

Morphological growth dynamics, mechanical stability, and active microtubule mechanics underlying spindle self-organization

Tatsuya Fukuyama, Lucan Yan, Masahito Tanaka, Megumi Yamaoka, Kei Saito, Shih-Chieh Ti, Chung-Chi Liao, Kuo-Chiang Hsia, Yusuke T. Maeda, Yuta Shimamoto

Summary: The spindle is a dynamic intracellular structure essential for chromosome segregation during cell division. It can exhibit varied shape morphologies through nonrandom, bistable self-organization paths. The emergence of different spindle shapes is influenced by both physical and molecular factors.

Anatomy of the fungal microtubule organizing center, the spindle pole body

Sue L. Jaspersen

Summary: The fungal kingdom is characterized by its vast diversity in ecology, life cycles, and morphology, with the spindle pole body (SPB) exhibiting significant variation among different fungi at a cellular level. Despite differences in morphology, many SPB components are conserved, pointing to commonalities in structure, function, and duplication. Advances in genomics, genetics, and cell biology have accelerated our understanding of SPB architecture in other fungi, providing insights into microtubule nucleation and other conserved processes across eukaryotes.

Genome Dominance in Allium Hybrids (A. cepa x A. roylei)

David Kopecky, Olga Scholten, Joanna Majka, Karin Burger-Meijer, Martin Duchoslav, Jan Bartos

Summary: Genome dominance is observed in wide hybrids, where one parental genome becomes dominant over the other, leading to unequal retention of parental chromosomes in successive generations. Female meiotic drive is identified as the key factor underlying this dominance, with variations in strength across different chromosome segments.

Phosphorylation controls spatial and temporal activities of motor-PRC1 complexes to complete mitosis

Agata Gluszek-Kustusz, Benjamin Craske, Thibault Legal, Toni McHugh, Julie P. Welburn

Summary: During mitosis, the microtubule crosslinker protein PRC1 recruits motor proteins CENP-E and Kif4A to the central spindle to coordinate chromosome segregation and cytokinesis. This recruitment is mediated by a conserved hydrophobic motif and is spatially and temporally regulated by CENP-E. The interaction between PRC1 and microtubule motor proteins is essential for controlling chromosome partitioning, maintaining central spindle integrity, and ensuring cytokinesis during anaphase.

Reduced Genotoxicity of Gold Nanoparticles With Protein Corona in Allium cepa

Sagar S. Arya, James E. Rookes, David M. Cahill, Sangram K. Lenka

Summary: This study observed significant genotoxicity in off-target bioindicator cells treated with high concentrations of green-synthesized vanillin capped gold nanoparticles, while protein-coated gold nanoparticles of similar concentrations had negligible genotoxic effects. These findings suggest that the toxicological signatures of AuNPs are influenced by their interaction with biological systems.

Cytotoxic and genotoxic effects of clopyralid herbicide on Allium cepa roots

Eslem Amac, Recep Liman

Summary: This study evaluated the dose-dependent cytotoxicity and genotoxicity of clopyralid on Allium cepa roots, showing that clopyralid affects root growth and induces chromosome abnormalities at different concentrations. These results confirm the cytotoxic and genotoxic effects of clopyralid on non-target organisms.

Allium cepa test vs. insecticides: a scientometric and meta-analytical review

Thais Fernandes Mendonca Mota, Amanda Roberta Sampaio, Marina Wust Vasconcelos, Nedia de Castilhos Ghisi

Summary: This systematic review focused on the effect of insecticides on the Allium cepa system. The meta-analytical test showed that insecticide treatment increased the number of micronuclei in onion cells and reduced the mitotic index. More studies on biotechnology, nanotechnology, and biopesticides are needed to develop safer pesticides.

The Dictyostelium Centrosome

Ralph Graef, Marianne Grafe, Irene Meyer, Kristina Mitic, Valentin Pitzen

Summary: The centrosome of Dictyostelium amoebae consists of a cylindrical layered core structure without centrioles, surrounded by a corona harboring microtubule-nucleating gamma-tubulin complexes. Proteomics, protein interaction studies, and superresolution microscopy methods have significantly advanced our understanding of the composition, structure, and function of this centrosome type. Comparisons of the components of the Dictyostelium centrosome with those of animals and yeasts have been discussed.

Anthracnose of Onion (Allium cepa L.): A Twister Disease

Ram Dutta, K. Jayalakshmi, Sharath M. Nadig, Dalasanuru Chandregowda Manjunathagowda, Vishal S. Gurav, Major Singh

Summary: Onions are a valuable vegetable-spice crop in India but are susceptible to diseases caused by fungi, bacteria, viruses, and nematodes. Anthracnose, caused by Colletotrichum spp., is a major issue as it severely affects bulb production. Twister disease is a common problem in onion production, particularly in humid regions, reducing productivity and value. This review provides updated knowledge on onion anthracnose, including the pathogen, disease cycle, infection pathways, and management techniques to benefit growers.

Summary: Flowering plants contain multiple cyclin families, with B1-type cyclins playing a crucial role in cell cycle control during Arabidopsis development. Mutant analysis revealed complex overlapping requirements of B1-type cyclins, with CYCB1;2 being central. The double mutant cycb1;1 cycb1;2, although compromised in growth, provides a unique opportunity to study the function of B1-type cyclins at the organismic level.

Summary: Octocrylene sunscreen is widely present in different environments. This study investigates its adverse effects on terrestrial plants and soil fauna. The results show that octocrylene negatively affects seed germination, root elongation, and cell division in Allium cepa, as well as avoidance behavior and oxidative stress in Eisenia fetida. The presence of octocrylene in soil fertilization and irrigation water may have a negative impact on the survival of species relying on the soil.
