Improvement of haploid and doubled haploid plants using wheat anther culture

Revue Marocaine des Sciences Agronomiques et Vétérinaires, 2018
The production of haploids and double haploids, are widely used techniques in advanced breeding programs to speed-up the production of homozygote lines. Anther culture is one of the processes of induction and regeneration of haploids and double haploids ...

Microbial Odorant Detection Guides Drosophila Parasitoids Seeking Hosts in Fermenting Fruits

Advanced Science, EarlyView.
Yeast microbes in fermenting fruits attract both host flies and their parasitoid wasps. Female Leptopilina boulardi detect yeast‐emitted ethyl esters via two olfactory receptors, LbouOR167 and LbouOR136. A conserved residue, Leu159, is critical for binding these compounds, enabling female wasps to locate host‐rich habitats.

Development of haploid winter wheat by the method of distant hybridization with maize

Зерновое хозяйство России
In order to improve the breeding process and expand the genetic diversity of winter wheat, haploid lines can serve as new initial material. One of the methods for developing haploids in wheat plants is distant hybridization when crossing with maize ...

MIS12 Is Required for Kinetochore‐Microtubule Attachment in Oocyte Meiosis

Advanced Science, EarlyView.
A model depicting the role of MIS12 in K‐MT attachment during oocyte meiosis. The presence of MIS12 stabilizes bipolar K‐MT attachments by maintaining the function of NDC80 and its interaction with TUBB. This, in turn, promotes KNL1 assembly and subsequent SAC protein recruitment to kinetochores.

Efeitos de meios de cultura na formação de calos a partir de anteras de aspargo (Asparagus officinalis L.) Effects of the culture media on the calli formation from Asparagus officinalis L. anthers

Acta Botânica Brasílica, 1995
Técnicas auxiliares, como a cultura de anteras, possibilitam melhor eficiência na obtenção de novos genótipos de aspargo. Neste trabalho, foram utilizadas anteras contendo grãos de pólen, no estágio uninucleado, dos híbridos 56x22-8 e 47x22-8, em meio MS,

From Cytoskeletal Remodeling to Oocyte Quality: The Emerging Role of Mechanics

Advanced Science, EarlyView.
Mechanical properties of the oocyte are increasingly recognized as critical determinants of meiotic success and developmental potential. How actomyosin remodeling controls oocyte mechanics, how these properties are altered in pathological conditions, and how they could serve as markers in reproductive medicine are examined.

Effect of genotypic background on haploid production through embryo rescue in wheat × maize crosses - Short Communication

Plant, Soil and Environment, 2005
Two high yielding wheat (Triticum aestivum L.) varieties were pollinated with seven agrarian superior varieties. F1's thus obtained were pollinated with diverse winter maize lines/composites and treated with a solution containing 2,4-D and GA3.

The power of many: when genetics met yeasts and high‐throughput

Biological Reviews, EarlyView.
ABSTRACT In recent years, complex technological capabilities have evolved, driven by the need to solve complex and integrative biological questions through global analyses. New equipment allows the scaling up and automation of processes which previously were carried out on a very limited scale.

Discovery of an Atypical Arp2/3 Complex in Malaria Parasites Sheds New Light on Nuclear Actin

Cytoskeleton, EarlyView.
ABSTRACT The Arp2/3 complex is a key actin nucleator essential for cytoskeletal dynamics in eukaryotes. Previously believed absent in apicomplexan parasites, we recently identified an atypical Arp2/3 complex in malaria parasites consisting of five divergent subunits and a putative kinetochore‐associated factor.
