КОМПЛЕКС ПАТОГЕНОВ НА ОВОЩНЫХ КУЛЬТУРАХ В УСЛОВИЯХ ЦЕНТРАЛЬНОГО РЕГИОНА РФ

As a result of monitoring of causative agents of diseases of vegetable crops and studying of its species specification, the genus and species of fungi and bacteria, were found. Previously unknown in the Central region of Russia pathogens of carrot were identified: Sclerotinia nevales, Gleocladium roseum, Verticillium spp, Trichotecium roseum, Streptomyces scabies, F. nivale, F. chlamidosporum, F. equiseti, F. proliferatum, Chaetomium spp., Erysiphe umbelliferum, Erwinia carotovora. Main causative agents of diseases  of carrot during storage were also described: Alternaria infectoria, A. alternatа, A. arborescens, A. radicina, A. cheiranthi, A. corotiincultae, A. cinerariae, Embellisia spp., Nimbia spp., Cladosporium spp. It was found new pathogen for onion (Aspergillus niger), garlic (Fusarium semitectum, F. subglutinans, F. proliferatum, F.avenacium), red beet (Typhula ishikariensis), and radish (Drechslera Bondartseva).В результате проведенного мониторинга возбудителей болезней овощных культур и изучения их видовой принадлежности выделены роды и виды грибов, фитопатогенных бактерий, незарегистрированных в условиях Центрального региона РФ. Выделены и идентифицированы ранее неизвестные патогены на моркови: Sclerotinia nevales, Gleocladium roseum, Verticillium spp, Trichotecium roseum, Streptomyces scabies, F. nivale, F. chlamidosporum, F. equiseti, F. proliferatum, Chaetomium spp., Erysiphe umbelliferum, фитопатогенная бактерия Erwinia carotovora. Основными возбудителями моркови в период хранения являются альтернариоидные гифомицеты: Alternaria spp., Ulocladium spp., Embellisia spp., Stemphillium spp., Nimbia spp. Выделены и идентифицированы новые виды рода Alternaria, вызывающие бурую пятнистость листьев,- A. infectoria, A. alternatа, A. arborescens и гифомицеты родов Embellisia spp.и Nimbia spp. В патогенезе черной гнили моркови в период хранения участвуют виды Alternaria: A. radicina, A. cheiranthi, A. corotiincultae, A. cinerariae, Cladosporium spp. На луке зафиксирован новый для Центральной Зоны РФ патоген Aspergillus niger, вызывающий черную плесень к концу вегетации и в период хранения. На чесноке озимом выделены и описаны четыре новых вида рода Fusarium: F. semitectum, F. subglutinans, F. proliferatum и F.avenacium. На корнеплодах свеклы столовой – Typhula ishikariensis, на семенах редиса – Drechslera Бондарцева

ВНИМАНИЮ ЛУКОВОДОВ - ЧЕРНАЯ ПЛЕСЕНЬ ЛУКА

The black mold of several varieties of onion was found in our zone of cultivation. The causative agent was identified as Aspergillus niger Tieghem 1867. The degree of damage by this disease grades and depends on temperature optimal for growth and sporulation of fungi.Зафиксировано ранее не наблюдавшееся в нашей зоне сильное поражение ряда сортов лука репчатого черной плесенью, возбудитель которой идентифицирован как Aspergillus niger Tieghem 1867. Установлена разная степень поражения сортов этим заболеванием и зависимость роста и спороношения гриба от температуры

ВОЗБУДИТЕЛЬ ГНИЛЕЙ РАСТЕНИЙ СЕМЕЙСТВА СЕЛЬДЕРЕЙНЫЕ – ГРИБ TRYCHOTHECIUM ROSEUM L.

The etiology and pathogenicity of this pathogen were studied.Выявлен ранее малоизвестный и малораспространенный на моркови патоген Trychothecium roseum L. Изучена этиология возбудителя и патогенность его на растениях семейства Сельдерейные

ИММУНОПАТОГЕНЕЗ ОСТРЫХ РЕСПИРАТОРНЫХ ИНФЕКЦИЙ, ТАКТИКА РАЦИОНАЛЬНОГО ВЫБОРА ЭТИОТРОПНОЙ И ИММУНОМОДУЛИРУЮЩЕЙ ТЕРАПИИ У ДЕТЕЙ

The article demonstrates that the basis for pathogenesis of acute respiratory infection (ARI ) is a deficiency in a number of factors of virus protection. This deficiency manifests itself through low concentration of interferon and secretory IgA in the nasal mucosa at higher levels of IL-8, alongside with low serum antiviral activity and significant inhibition of interferon production and reduction of the compensatory mechanisms of adaptive immunity. These disorders require prescription of alpha-interferon preparations. For infants and children with a burdened pre-morbid background, regardless of age, such preparations can be administered with all clinical forms of ARI; in older children — with severe forms, including complications. Alpha-interferon preparations can be introduced at in any stage of the disease. Combination therapy with alpha-interferon drugs (VIFERON® suppositories and VIFERON® ointment) allows for enhanced clinical and immunological effects of therapy.Показано, что в основе патогенеза острых респираторных инфекций (ОРИ) лежит дефицит комплекса факторов противовирусной защиты, представленный низкой концентрацией интерферонов и секреторного IgA на слизистой оболочке носоглотки при повышении уровня ИЛ-8, низкой противовирусной активностью сыворотки крови и значимым угнетением интерфероногенеза, снижением компенсаторных механизмов адаптивного иммунитета. Указанные нарушения требуют коррекции с включением на любой стадии заболевания препаратов альфа-интерферона, у детей младшего возраста и детей с отягощенным преморбидным фоном независимо от возраста при всех клинических формах ОРИ, у старших детей — при тяжелых формах, в том числе осложненных. Комбинированная терапия с использованием препаратов альфа-интерферона (ВИФЕРОН® суппозитории и ВИФЕРОН® мазь) позволяет усилить клинико-иммунологические эффекты терапии

Mutation increasing β-carotene concentrations does not adversely affect concentrations of essential mineral elements in pepper fruit

<div><p>Vitamin and mineral deficiencies are prevalent in human populations throughout the world. Vitamin A deficiency affects hundreds of millions of pre-school age children in low income countries. Fruits of pepper (<i>Capsicum annuum</i> L.) can be a major dietary source of precursors to Vitamin A biosynthesis, such as β-carotene. Recently, pepper breeding programs have introduced the orange-fruited (<i>of</i>) trait of the mutant variety Oranzheva kapiya, which is associated with high fruit β-carotene concentrations, to the mutant variety Albena. In this manuscript, concentrations of β-carotene and mineral elements (magnesium, phosphorus, sulphur, potassium, zinc, calcium, manganese, iron and copper) were compared in fruit from P31, a red-fruited genotype derived from the variety Albena, and M38, a genotype developed by transferring the orange-fruited mutation (<i>of</i>) into Albena. It was observed that fruit from M38 plants had greater β-carotene concentration at both commercial and botanical maturity (4.9 and 52.7 mg / kg fresh weight, respectively) than fruit from P31 plants (2.3 and 30.1 mg / kg fresh weight, respectively). The mutation producing high β-carotene concentrations in pepper fruits had no detrimental effect on the concentrations of mineral elements required for human nutrition.</p></div
