Article
Cold stress is one of the main causes of yield losses in plant production in temperate climate areas. Cold stress slows down and even stops plant growth and development and causes injuries that may result in the plant's death. Cucumber (Cucumis sativus L.), an economically important vegetable, is sensitive to low temperatures, thus improving cold t...

One of the most important cucumber diseases is bacterial angular leaf spot (ALS), whose increased occurrence in open-field production has been observed over the last years. To map ALS resistance genes, a recombinant inbred line (RIL) mapping population was developed from a narrow cross of cucumber line Gy14 carrying psl resistance gene and suscepti...

Plants predominantly show maternal transmission of mitochondrial DNA (mtDNA). One known exception is cucumber, in which the mtDNA is paternally inherited. However, the mechanisms regulating this unique mode of transmission are unclear. Here we monitored the amounts of mtDNA throughout the development of cucumber microspores into pollen and observed...

Article
In cucumber, low temperatures can result in chilling injuries and can lead to significant yield decreases in open field production. The lack of a cold-tolerant cucumber germplasm has limited classical breeding. Recent progress in understanding plant response to cold stress has allowed to develop transgenic approaches to improving cold tolerance in...

Trichoderma strains that are beneficial to both the growth and health of plants can be used as plant growth-promoting fungi (PGPF) or biological control agents (BCA) in agricultural and horticultural practices. In order to select PGPF or BCA strains, their biological properties and taxonomy must be carefully studied. In this study, 104 strains of T...

Alternative oxidase (AOX) is a mitochondrial terminal oxidase which is responsible for an alternative route of electron transport in the respiratory chain. This nuclear-encoded enzyme is involved in a major path of survival under adverse conditions by transfer of electrons from ubiquinol instead of the main cytochrome pathway. AOX protects against...

Conference Paper
Plants possess two types of organellar terminal oxidases that are mitochondrial or chloroplast enzymes. Both are involved in the major life processes: cell respiration and photosynthesis. In plants AOX is usually encoded by two genes AOX1 and AOX2. Usually AOX1 gene is expressed under stress conditions and AOX2 is expressed constitutively. PTOX is...
