A soft rot of fruits caused by Mucor racemosus occurred on cherry tomato collected in Agricultural Products Wholesale Market in Jinju, Korea. The disease infection usually occurred wounded areas after cracking of fruits. At first, the lesions started with water soaked and rapidly softened and diseased lesion gradually expanded. Colonies were white to brownish to gray in color. Sporangia were 32...

Several studies have been conducted on resistance sources to improve the genetic resistance of farm-grown tomatoes to arthropod pests, including phytophagous mites. In the present study, we evaluate the behavior of the two-spotted spider mite on different cherry tomato accessions to identify possible sources of resistance (repellent effect) to this pest. Sixty-four accessions of cherry tomatoes...

in order to study the effects of ga3and cacl2 treatments in resolve the problems of sweet pepper culture in ilam region (including small size fruits with sunscald and blossom end rot disorders), this study was carried out in ilam university in 2012. for that, ga3 (50 mg/l) and cacl2 (0.5%) treatments were sprayed at two (fruit set and 15 days thereafter) and three (fruit set, 10 and 20 days the...

pectobacterium carotovorum is one of the most important bacterial pathogens of potato in the world.the expression of numerous genes including those involved in the production of virulence determinants in this bacterium are regulated by quorum sensing (qs). the signal molecules involved in qs in p. carotovorum belong to the group of n-acyl homoserine lactones (ahls). recently, several soil bacte...

Xanthomonas campestris pv. campestris is the causal agent of black rot on Brassicaceae. The draft genome sequences of three strains (CN14, CN15, and CN16) that are highly aggressive on Arabidopsis have been determined. These genome sequences present an unexpected genomic diversity in X. campestris pv. campestris, which will be valuable for comparative analyses.

the use of compounds inhibiting ethylene production is very important in post-harvest technology of fruits. sweet cherry is a non-climacteric fruit with capability of ethylene production during storage period. factors that decrease ethylene production would increase fruits storage life. in this research sweet cherry fruits of mashhad cv. were sprayed with different concentrations of salicylic a...
