We have investigated the origin of the Pto disease resistance (R) gene that was previously identified in the wild tomato species Lycopersicon pimpinellifolium and isolated by map-based cloning. Pto encodes a serine-threonine protein kinase that specifically recognizes strains of Pseudomonas syringae pv. tomato (Pst) that express the avirulence gene avrPto. We examined an accession of the distan...
The present investigation was carried out during Kharif season at the Horticulture Research centre of Sardar Vallabhbhai Patel University Agriculture & Technology, Meerut, U.P. 2020. D2 statistics applied to assess genetic divergence among 20 genotypes tomato using Mahalonobis analysis. experimental materials were planted in Randomized Block Design (RBD) with three replications. analysis va...
کنهی تارتن دولکهای به بسیاری از آفتکشهای مورد استفاده در مزارع گوجهفرنگی مقاوم شده است. یک روش جایگزین برای کنترل آفت، استفاده از گیاه میزبان مقاوم است که به وسیلهی کرکهای غدهای ایجاد میشود. در این تحقیق نقش کرکهای غدهای نوع IV در به دام انداختن و مرگ کنهی تارتن، در برگچههای دارای کرک و فاقد کرک لاینهای مختلف گونههای Lycopersicon hirsutum Humb & Bonpl (لاینهای LA1740، LA1777 و L...
Resistant and susceptible cultivars of tomato, lima beans, cotton, and alfalfa were tested with 10 populations of Meloidogyne incognita from different California locations. Nine of the populations differed in aggressiveness on the nine cultivars tested. Two populations were especially aggressive toward resistant tomato cultivars.
Tomato (Solanum lycopersicum L.) is an important vegetable crop and often cultivated in regions exposed to salinity and high temperatures (HT) which change plant architecture, decrease canopy light interception and disturb physiological functions. However, the long-term effects of salinity and HT combination (S+HT) on plant growth are still unclear. A dynamic functional-structural plant model (...
The occurrence of zoosporangia and oospores is analyzed for 88 field populations of Phytophthora infestans (Mont.) de Bary in Moscow region and other regions of Russia from 1997 to 2006. For estimation of zoosporangia and oospore frequencies in the populations, the indexes IZ (for zoosporangia) and IO (for oospores) are suggested. The combinations of these indexes enabled a reveal of 4 strategi...
