Opis:
Genetical analyses were conducted to find linkages and the locus of the gene calf on the Pisum chromosome map. The recessive, pleiotropic gene calf (enlarged and undulated leaflets, stipules, flowers and pods, plant sterile), artificially induced (the initial line-Large Podded G-20, the mutagene-DES and NMU) was described by Sharma in 1975. An identical mutant gene at the same locus was isolated in our research (the initial line - cv. Pegro, the mutagene - fast neutrons). Two lines were included in the Pisum gene bank - the type line for the gene calf - Wt 15873 and the representative line - Wt 16024. In linkage studies the representative line was crossed with tester lines bearing gene markers. Analyses of dihybrid segregation in F₂ generations revealed linkages of the gene calf with chromosome 2 markers. Two isozymic markers helped to reveal the calf locus on chromosome 2 with the following gene order: Orp - Calf - K - Pgm-p - Fum. This is in agreement with the current Pisum linkage map.

Opis:
At the plants’ exposal to abiotic stress, organic acids, including citric acid, are exuded through their roots. Previous studies have suggested that the exogenous application of citric acid increases antioxidant activity within the plant. Thus, we postulated that organic acids released into the surroundings during times of environmental stress may function as signaling molecules to increase antioxidant enzyme activity. To gain further insight into this phenomenon, we identified individual organic acids exuded from the roots of leafy vegetables under drought stress. We then analyzed enzyme activity and the root/shoot lengths of seedlings after treatment with the types of organic acids found to be exuded from the studied leafy vegetables, including acetic, citric, lactic, and tartaric acids. There was a significant increase in catalase and ascorbate peroxidase enzyme activity in Napa cabbage (Brassica rapa var. pekinensis) after exogenous citric acid application. Root lengths of cabbage (Brassica oleracea var. capitata) and Napa cabbage seedlings were significantly longer in citric and lactic acids pretreated seedlings compared to those of the control. The above results support the conclusion that exogenous application of citric acid alleviates drought stress. However, there is insufficient evidence to prove that organic acids act as signaling molecules to prime neighboring plants for upcoming stress.

Opis:
Aphids are one of the most important economic pests and vectors of viral diseases in crops. Brevicoryne brassicae L., one of the most serious aphid pests in Brassicaceae, if not controlled, often reaches very high densities. The present study compared the systemic effects of ethanolic, methanolic and aqueous Melia azedarach L., Peganum harmala L., Calendula officinalis L. and Otostegia persica Boissier extracts with two systemic pesticides, acetamiprid and pirimicarb (at the maximum label-recommended rate). Population growth percentages of B. brassicae through leaf spraying under greenhouse conditions were assessed. The chemicals were sprayed on one of the leaves in greenhouse condition. The results indicated that all the plant extracts have systemic effects at different levels. Among different extracts, O. persica ethanolic extract, P. harmala methanolic extract and M. azedarach aqueous extract resulted in a reduction of the B. brassicae population

Opis:
Cabbage plants showing symptoms of leaf spot were detected from various fields in the Almaty region of Kazakhstan in the winter seasons of 2015 and 2016. The disease incidences of approximately 50% were recorded in various fields visited in the Almaty region. The pathogen was aseptically isolated from the symptomatic leaves and maintained in an in vitro culture media. Morphological characteristics and sporulation of the fungus was determined under both light and electron microscopy. The extracted genomic DNA of the fungi was subjected to Polymerase Chain Reaction (PCR) using ABCsens/ABCrev and ITS1/ITS4 primers amplifying ABC transporter (Atr1) gene and the internal transcribed spacer regions, respectively. The amplified products of PCR were sequenced, aligned, blasted and compared for similarity with other species in the NCBI GenBank. The cluster analysis result showed 99% homology with related fungi retrieved from the NCBI GenBank for the ITS region. The fungal isolate was pathogenic towards twenty-two-day-old plants, namely, Brassica oleracea, Lycopersicon esculentum, Solanum melongena, and was established as the causal agent of leaf spot on these plants. This is the first record implicating A. brassicae for black leaf spot disease of cabbage in Kazakhstan.
