this study investigated the effect of carboxymethyl cellulose (cmc), tragacanth, and saalab hydrocolloids in two concentrations (0.3 and 0.7%) and different frying media (refined canola oil (rco), rco+1% bene kernel oil (bko), and rco+1 mg l-1 unsaponifiable matter (usm) of bko on acrylamide formation in fried potato slices. the hydrocolloid coatings significantly reduced acrylamide formation i...

concentration of co2 in the atmosphere is likely to increase up to 550 µmol mol-1 by the middle of 21st century. such an increase in the atmospheric co2 would affect plant growth, and as well the productivity of crop plants. a field experiment was conducted with two potato cultivars namely kufri surya and kufri chipsona-3 grown inside open top chambers (otcs) at ambient (385±30 µmol mol-1) vs. ...

SNPs in genes functional in starch-sugar interconversion associate with natural variation of tuber starch 1 and sugar content of potato (Solanum tuberosum L). 2 L. Schreiber , A. C. Nader-Nieto , E.

The transformation of amyloplast into chloroplasts in potato (Solanum tuberosum L.) tuber tissue can be induced by light. Excised potato tuber discs illuminated with white light of 3000 lux began to synthesize chlorophyll after a lag period of 1 day, and continued to synthesize chlorophyll for 3 weeks. In this paper we present evidence, based on ultracentrifugal sedimentation and immunoprecipit...

We cloned a 9.4-kb DNA fragment from Streptomyces scabies ATCC 41973 that allows the nonpathogen Streptomyces lividans 66 TK24 to necrotize and colonize potato tuber slices and produce scab-like symptoms on potato minitubers. Deletion analysis demonstrated that activity was conferred by a 1.6-kb DNA region. Sequence analysis of a 2.4-kb DNA fragment spanning the DNA region necessary for activit...

Vegetative propagation of potato allows the dissemination of viruses that can cause drastic drops in tuber yield. Potato virus Y (PVY) is one of the most important viruses of potato due to the non-persistent mode of transmission through vector insects. Genetic resistance is the recommended control measure since the chemical control of vector insects is not effective. This study aimed to identif...

phosphorylatson, if any, only occurs in later stages of infection. Isolation of mitochondria (Mw) from potato tuber tissue (Solanum tuberosum L.) which are reasonably intact and show respiratory control by adenosine diphosphate (ADP) has been des cribed recently.3,4) The present paper deals with some properties of Mw prepared from healthy, infected and cut potato tuber tissues. The method of ex...

Potato soft rot, caused by the pathogenic bacterium Lelliottia amnigena (Enterobacter amnigenus), is a serious and widespread disease affecting global potato production. Both salicylic acid (SA) proline (Pro) play important roles in enhancing tuber resistance to rot. However, combined effects of SA Pro on defense responses tubers L. infection remain unknown. Hence, controlling newly emerging ro...
