Current study aimed to search for safe and effective natural products to control the potato soft-rot disease, Erwinia carotovora subsp. carotovora. Antibacterial efficiency of edible mushroom extracts (MEs) and garlic essential oil (EO) were compared with two bactericides; streptrol and oxolinic acid as well as two fungicides; mancopper and copper oxychloride. Bioassay experiments were conducte...

The isotherm for isocitrate oxidation by potato (Solanum tuberosum L. var. Russet Burbank) mitochondria in the presence of exogenous NAD is characterized by a hyperbolic phase at isocitrate concentrations below 3 millimolar, and a sigmoid, or positively cooperative phase from approximately 3 to 30 mllmlar. The two forms of isocitrate dehydrogenase were separated and characterized following the ...

This paper discusses the use of various methods to distinguish between slices sweet potato dried in different conditions. The drying conditions varied terms temperature, values were: 60 °C, 70 80 and 90 °C. Examination included instrumental texture analysis using a texturometer digital based on macroscopic images. Classification acquired data involved machine learning techniques types artificia...

N-Acylhomoserine lactones (AHLs) are used as quorum-sensing signal molecules by many Gram-negative bacteria. We have reported that Microbacterium testaceum StLB037, which was isolated from the leaf surface of potato, has AHL-degrading activity. In this study, we cloned the aiiM gene from the genomic library of StLB037, which has AHL-degrading activity and shows high homology with the alpha/beta...

One of the earliest consequences of slicing plant storage organs such as potato tubers into thin disks is the formation of polysomes, which in potato slices is complete after 9 hours and is dependent on transcription. Fresh disks do not incorporate 32P, 3H-uridine or 14C-leucine into their ribosomes, whereas ribosomes and polysomes of aged disks use these precursors effectively. This developmen...

Figure 3 In October 2013, in a plantain farm in El Carmen canton in Manabí, Ecuador, the occurrence of wilted plants of cv. Barraganete with necrosis in vascular tissue of rhizomes and pseudostem was observed. Fruits were observed to ripen prematurely and exhibited an internal dry rot. Reddish necrotic spots were also noted in the rachis of the diseased bunches (Fig. 1). Symptoms resembled thos...

Exposure of root tissue from a susceptible variety of sweet potato to low concentrations of ethylene induced a resistance to infection by Ceratocystis fimbriata and an increase in the activity of peroxidase and polyphenoloxidase in the tissue. Susceptible tissue that was inoculated with a pathogenic strain of C. fimbriata or a nonpathogenic strain that can induce resistance liberated more ethyl...

Open sun drying (OSD) is the most common method of crop drying in developing countries. Despite several disadvantages, it is widely practiced because it is a simple way of drying. Crop temperature, temperature around the crop, solair temperature, and rate of moisture evaporation are the important parameters in OSD. The thermal behavior of OSD of green chillies, green pea, white gram (kabuli cha...
