Examples of atypical structure the embryonic apparatus indicator plants in Donbas are highlighted. Many years experience conducting phytoindication experiments (1998–2022) made it possible to identify accounting sites with contrasting geochemical characteristics and monodominant ingredient pollution. Registered abnormalities considered as variants extreme structural polymorphism natural flora u...

The subgroup II luteovirus barley yellow dwarf virus-RPV (BYDV-RPV) acts as a helper virus for a satellite RNA (satRPV RNA). The subgroup II luteovirus beet western yellows virus (BWYV) and the ST9-associated RNA (ST9a RNA), a BWYV-associated RNA that encodes a polymerase similar to those of subgroup I luteoviruses, were assayed for their ability to support replication of satRPV RNA. SatRPV RNA...

Capsella bursa-pastoris (L.) Medik. (Brassicaceae) is a wild herb with high nutritional value that can be eaten raw or cooked. A metabolomic study was performed with different extracts of its aerial parts that were tested concerning their antiradical, acetylcholinesterase inhibitory and antibacterial activities. Phenolic compounds were identified and quantified by HPLC-DAD, organic acids and am...

Low temperature affects gene regulatory networks and alters cellular metabolism to inhibit plant growth. Peroxidases are widely distributed in plants and play a large role in adjusting and controlling reactive oxygen species (ROS) homeostasis in response to abiotic stresses such as low temperature. The Rare Cold-Inducible 35 gene from Capsella bursa-pastoris (CbRCI35) belongs to the type III pe...

Field experiments were conducted to study weed population shifts in long-term conservation tillage systems. The objectives of this study were to determine weed community abundance, diversity and composition on conventional tillage (CT), minimum tillage (MT), no-tillage with paraplow (ZT) and no-tillage (NT) systems, and to identify species that are associated with specific tillage systems. The ...

An activation tagging screen in which the cauliflower mosaic virus 35S enhancer was inserted randomly into an Arabidopsis genome homozygous for the floral homeotic mutation apetala2-1 (ap2-1) resulted in a line (28-5) with extraordinarily wide, heart-shaped ovaries. The ovary of the 28-5 ap2-1 mutant shows an oval shape because of increased numbers of enlarged cells. When the ap2-1 mutation is ...

Alfalfa is one of the most important perennial fodder crops, and it also economical. provides first class that suitable for feeding all livestock, especially ruminants. Grass broadleaf weeds are a serious threat to quality viability alfalfa stands. Weeds can reduce nutritional value crop cause significant reductions in yield, as they compete aggressively water, nutrients, sunlight, space. In th...

Four species of Mesopolobus Westwood were reared as parasitoids of Ceutorhynchinae hosts in Europe during surveys in 2000-2004. An illustrated key is given to differentiate the four species, M. gemellus Baur & Muller sp. n., M. incultus (Walker), M. morys (Walker) and M. trasullus (Walker), plus M. moryoides Gibson, a parasitoid of the cabbage seedpod weevil, Ceutorhynchus obstrictus (Marsham),...
