Segregation analysis between Lysopersicon esculentum (cultivated tomato) and L. hirsutum (wild form) in conjunction with positional verification by using near-isogenic lines demonstrated that biosynthesis of two structurally different classes of sesquiterpenes in these species is controlled by loci on two different chromosomes. A locus on chromosome 6, Sesquiterpene synthase1 (Sst1), was identi...
Purpose: To evaluate the glucosidase inhibitory and cytotoxic activities of five selected edible and medicinal ferns, namely, Blechnum orientale, Davallia denticulata, Diplazium esculentum, Nephrolepis biserrata, and Pteris vittata. Methods: The aqueous extracts of the five ferns were prepared by water extraction at 90 oC for 1 h. Antiglucosidase assay was used to determine the effect of each e...
در پژوهش حاضر، توانایی دگر آسیبی گیاه مورخوش (zhumeria majdae rech. f. & wendelbo) مطالعه شد. اثر عصاره آبی برگ گیاه مورخوش بر درصد و سرعت جوانه زنی بذرهای هفت گونه از سبزیجات گوجه فرنگی lycopersicon) esculentum)، کاهوlactuca sativa))، کلم brassica oleracea))، تره (allium porrum)، تربچه (raphanus sativus)، پیاز (alliumcepa) و شاهی lipidium sativum)) مورد بررسی قرار گرفت. عصاره آبی برگ گیاه ...
two-spotted spider mite (tssm) is becoming resistant to many of the pesticides used in the tomatofields. a potential alternative method of control is host plant resistance, which may be mediated byglandular trichomes. in this experiment, level of entrapment and mortality of the pest by type ivglandular trichomes were studied on accessions of lycopersicon hirsutum humb & bonpl, l. pennellii(cor....
DnaJ proteins act as essential molecular chaperones in protein homeostasis and protein complex stabilization under stress conditions. The roles of a tomato (Lycopersicon esculentum) chloroplast-targeted DnaJ protein (LeCDJ1), whose expression was upregulated by treatment at 4 and 42 °C, and with high light, NaCl, polyethylene glycol, and H2O2, were investigated here using sense and antisense tr...
Forty-three Fusarium oxysporum strains and one Fusarium solani strain were analyzed for genetic diversity. These strains represent a wide range of geographic locations and were collected primarily from tomato (Lycopersicon esculentum) roots. Among all 43 F. oxysporum strains, 21 were not pathogenic to tomato, 20 were pathogenic, including 13 strains of Fusarium oxysporum lycopersici and seven s...
Little is known of how plant disease resistance (R) proteins recognize pathogens and activate plant defenses. Rcr3 is specifically required for the function of Cf-2, a Lycopersicon pimpinellifolium gene bred into cultivated tomato (Lycopersicon esculentum) for resistance to Cladosporium fulvum. Rcr3 encodes a secreted papain-like cysteine endoprotease. Genetic analysis shows Rcr3 is allelic to ...
Studying antagonistic coevolution between host plants and herbivores is particularly relevant for polyphagous species that can experience a great diversity of host plants with a large range of defenses. Here, we performed experimental evolution with the polyphagous spider mite Tetranychus urticae to detect how mites can exploit host plants. We thus compared on a same host the performance of rep...
