Mass migration of hoverflies was observed near Prague city in a highly agricultural landscape, representing only the second record of hoverfly migration in the Czech Republic. This rare observation was likely driven by the need to rest, shelter and replenish energy, although most flowers had already finished blooming.

Cucurbit Leaf Crumple Virus: An Important Pathogen of Cucurbit and Snap Bean Crops
Cucurbit leaf crumple virus (CuLCrV) is an emerging pathogen in the New World. High whitefly abundance and transmission efficiency, mixed infections, weed reservoirs and limited host resistance challenge cucurbit and snap bean production. ABSTRACT Taxonomy Cucurbit leaf crumple virus (CuLCrV); Begomovirus cucurbitae; Geminiviridae; Geplafuvirales ...

SUMMARY Polyploids, particularly synthetic lines, often produce larger seeds than their diploid progenitors. However, little is known regarding the role of seed coat development in the larger seeds formation in polyploid plants. Here, we investigated the cellular and molecular basis by which seed coat development mediates seed enlargement in the ...

Abstract BACKGROUND Water scarcity and soil salinization are major constraints to irrigated agriculture in semi‐arid regions, affecting crop productivity and fruit quality. Combining deficit irrigation with biostimulant application has emerged as a promising strategy to improve water use efficiency and plant stress tolerance.

Mutagenesis of Raphanus sativus Using Ionizing Radiation [PDF]
Mutagenesis of Raphanus sativus was conducted using 10kR, 20kR, and 30kR radiation in an attempt to determine the dosage which produces most mutants without being lethal.
