Occurrence of small fruit viruses in Belarus

Epidemiological control of plant virus diseases is necessary for creation of small fruit nurseries and production of berries with stable high yields. Phytosanitary state of Rubus idaeus L. and Ribes sp. L. was studied in Belarus. The aim of the research was to determine the most widespread small fruit viruses and to select plants that free from all tested viruses for further propagation in vitro as a basis for Nuclear stock. The following viruses were identified: CMV, ApMV, SLRV, RRV, RBDV, ArMV, TBRV and ToRSV. High level of virus infection for small fruit plantations was shown. The most common viruses for all three crops (raspberry, red and black currant) were RRV, SLRV and ArMV. It was noted that infection level of viruses considerably varied from plant cultivars and crops.Keywords: Viruses, raspberry, black currant, red currant, Belaru

Onedata4Sci: Life science data management solution based on Onedata

Life-science experimental methods generate vast and ever-increasing volumes of data, which provide highly valuable research resources. However, management of these data is nontrivial and applicable software solutions are currently subject to intensive development. The solutions mainly fall into one of the two groups: general data management systems (e.g. Onedata, iRODS, B2SHARE, CERNBox) or very specialised data management solutions (e.g. solutions for biomolecular simulation data, biological imaging data, genomic data). To bridge this gap between them, we provide Onedata4Sci, a prototype data management solution, which is focused on the management of life science data and covers four key steps of the data life cycle, i.e. data acquisition, user access, computational processing and archiving. Onedata4Sci is based on the Onedata data management system. It is written in Python, fully containerised, with the support for processing the stored data in Kubernetes. The applicability of Onedata4Sci is shown in three distinct use cases -- plant imaging data, cellular imaging data, and cryo-electron microscopy data. Despite the use cases covering very different types of data and user patterns, Onedata4Sci demonstrated an ability to successfully handle all these conditions. Complete source codes of Onedata4Sci are available on GitHub (https://github.com/CERIT-SC/onedata4sci), and its documentation and manual for installation are also provided

ВЕГЕТАТИВНАЯ ПРОДУКТИВНОСТЬ РАСТЕНИЙ МАЛИНЫ (RUBUS IDAEUS L.) ПОСЛЕ КУЛЬТИВИРОВАНИЯ IN VITRO

The vegetative productivity of raspberry varieties Alyonushka and Meteor after in vitro propagation is evaluated, and the productivity of raspberry plants grown in different regions of Belarus is compared. It’s established that vegetative productivity of raspberry plants after in vitro depends on a variety, plants age, and the region of growing. The largest amount of young plants per one mother plant of Alyonushka variety was obtained after the first year of plant growing, and Meteor variety – after the third year. It’s shown that the vegetative productivity of Alyonushka variety is higher when it’s grown in Gomel region.Проведена оценка вегетативной продуктивности растений малины сортов Аленушка и Метеор в полевых условиях после культуры in vitro, а также сравнение продуктивности оздоровленных маточников при выращивании в разных областях Беларуси. Установлено, что вегетативная продуктивность растений малины после культуры in vitro зависит от сорта, возраста растений, а также региона возделывания маточника. Наибольшее количество саженцев с одного маточного куста у растений сорта Аленушка было получено в 1-й год эксплуатации маточника, а для растений сорта Метеор – на 3-й год. Показано, что вегетативная продуктивность растений сорта Аленушка была выше при выращивании растений в условиях Гомельской области.Ил. 1. Табл. 1. Библиогр. – 7 назв
