The tomato I-3 and I-7 genes confer resistance to Fusarium oxysporum f. sp. lycopersici (Fol) race 3 and were introgressed into the cultivated tomato, Solanum lycopersicum, from the wild relative Solanum pennellii. I-3 has been identified previously on chromosome 7 and encodes an S-receptor-like kinase, but little is known about I-7. Molecular markers have been developed for the marker-assisted...
تاکنون، تحقیقاتی در مورد سیتولوژی خزه (بریوفیت) های ایران انجام نگرفته است، لذا در این تحقیق، مطالعات کروموزومی روی پنج گونه از خزه ها شامل دو حالت (expression) و یک واریته به اسامی زیر برای نخستین بار در کشور صورت گرفت: amblystegium riparium (hedw.) b.s.g. “brevipes ” حالت(n=20) a. riparium (hedw.) b.s.g. “pennellii ” حالت(n=9, 9+m, 9+2m) a. serpens (hedw.) b.s.g. (n=20) campylium stellatum...
The effect of salinity on the antioxidative system of root mitochondria and peroxisomes of a cultivated tomato Lycopersicon esculentum (Lem) and its wild salt-tolerant related species L. pennellii (Lpa) was studied. Salt stress induced oxidative stress in Lem mitochondria, as indicated by the increased levels of lipid peroxidation and H(2)O(2). These changes were associated with decreased activ...
In order to screen for putative candidate genes linked to tomato fruit weight and to sugar or acid content, genes and QTLs involved in fruit size and composition were mapped. Genes were selected among EST clones in the TIGR tomato EST database (http://www.tigr.org/tdb/tgi/lgi/) or corresponded to genes preferentially expressed in the early stages of fruit development. These clones were located ...
Although self-incompatibility (SI) in plants has been studied extensively, far less is known about interspecific reproductive barriers. One interspecific barrier, known as unilateral incongruity or incompatibility (UI), occurs when species display unidirectional compatibility in interspecific crosses. In the wild tomato species Solanum pennellii, both SI and self-compatible (SC) populations exp...
