Despite the involvement of many members of the chitinase family in plant immunity, the precise functions of the majority of the members remain poorly understood. Herein, the gene ChiIV3 in Capsicum annuum encoding a chitinase protein containing a chitin binding domain and targeting to the plasma membrane was found to be induced by Phytophthora capsici inoculation (PCI) and applied chitin treatm...

The antifungal substances SH-1 and SH-2 were isolated from Streptomyces humidus strain S5-55 cultures by various purification procedures and identified as phenylacetic acid and sodium phenylacetate, respectively, based on the nuclear magnetic resonance, electron ionization mass spectral, and inductively coupled plasma mass spectral data. SH-1 and SH-2 completely inhibited the growth of Pythium ...

This study was conducted to determine the Phytophthora rot resistance of 514 accessions of watermelon germplasm, Citrullus lanatus var lanatus. About 46% of the 514 accessions tested were collections from Uzbekistan, Turkey, China, U.S.A., and Ukraine. Phytophthora capsici was inoculated to 45-day-old watermelon seedlings by drenching with 5 ml of sporangial suspension (10(6) sporangia/ml). At ...

Phytophthora species secrete a large array of effectors during infection of their host plants. The Crinkler (CRN) gene family encodes a ubiquitous but understudied class of effectors with possible but as of yet unknown roles in infection. To appreciate CRN effector function in Phytophthora, we devised a simple Crn gene identification and annotation pipeline to improve effector prediction rates....

Phytophthora capsici is a soil-borne plant pathogen with a wide range of hosts. The pathogen secretes a large array of effectors during infection of host plants, including Crinkler (CRN) effectors. However, it remains largely unknown on the roles of these effectors in virulence especially in P. capsici. In this study, we identified a cell death-inducing CRN effector PcCRN4 using agroinfiltratio...

Foot rot disease (Phytophthora capsici) causes severe economic losses to cultivators of black pepper. Fungicides used for managing the adversely affect export potential product due their residual toxicity. Endospore-forming bacterial strains, Bacillus amyloliquefaciens VLY24, pumilus VLY17, and velezensis PCSE10 were evaluated growth promotion suppression in pepper nursery at two locations Kera...

One single pathotype (race 0) was identified among eight tested isolates of Phytophthora capsici (Leonian) collected in northwest Spain, after inoculation tests using pepper cultivars of different origin, including the well known reference resistant cultivar Serrano Criollo de Morelos 334. Complete resistance to P. capsici was not found after the inoculation of 23 local genotypes of Capsicum an...

در این بررسی واکنش نه رقم بادمجان به بیماری ساق سیاه که در چند سال اخیر در مناطق مختلف استان کهگیلویه و بویراحمد مشاهده شده است مورد بررسی قرار گرفت. برای جداسازی عامل بیماری، بافت‌های آلوده بعد از شستشو با آب، به قطعات پنج میلی‌متر تقسیم و بدون ضدعفونی سطحی روی محیط کشت نیمه انتخابی CMA-PARP کشت شدند. از بافت‌های آلوده هجده جدایه به دست آمد که بر اساس خصوصیات مورفولوژیک و نیاز دمایی پرگنه‌های ...

Tests in vitro conditions with ethanol extracts from the radix of Berberis vulgaris and flower twig Tamarix tetrandra prepared by method maceration were performed two economically important plant pathogens such as Monilia laxa Phytophthora capsici. The received results show that common barberry (Berberis vulgaris) are able to fully block growth mycelium at 0.5 % (m/v) concentration during entir...

Plant growth promoting rhizobacteria (PGPR) are the rhizosphere bacteria that may be utilized to augment plant growth and suppress plant diseases. The objectives of this study were to identify and characterize PGPR indigenous to cucumber rhizosphere in Bangladesh, and to evaluate their ability to suppress Phytophthora crown rot in cucumber. A total of 66 isolates were isolated, out of which 10 ...
