Amorphophallus campanulatus, Alocasia indica and Colocasia esculenta are very popular for their edible corms and leaves, especially in Assam and Bengal and are cultivated there as common food crops. Besides, they are also considered as medicinal plants in Sushruta Samhita and Ayurveda. So, the ethanolic extracts of these tubers were screened for the presence of in vitro antioxidant potential ag...

The changes in the components of the ascorbateglutathione system during the storage of potato {Solanum tuberosum L. cv. Spunta) tubers for 40 weeks at both 3 C and 9 C were studied in relation to lipid peroxidation. The level of malondialdehyde was found to be higher at 3 C than at 9 C throughout storage. Thus, lipid peroxidation, which is the main cause of membrane deterioration, was accelerat...

Glucosyloxybenzyl 2-isobutylmalates are one group of important active constituents in the tubers of Gymnadenia conopsea R. Br. and Coeloglossum viride (L.) Hartm. var. bracteatum (Willd.). For the purpose of quality evaluation of these two Chinese herbal medicines, it is necessary to use a rapid and reliable assay that is suitable for the determination of their active constituents. A high-perfo...

Pinellia ternata tuber is one of the well-known Chinese traditional medicines. In order to understand the pharmacological properties of tuber proteins, it is necessary to perform proteome analysis of P. ternata tubers. However, a few high-abundance proteins (HAPs), mainly mannose-binding lectin (agglutinin), exist in aggregates of various sizes in the tubers and seriously interfere with proteom...

An algorithm which helps detecting in-line potato tubers without singulation when they are mixed with clods was developed. It is particularly useful for sorting and grading purposes whether at the packhouses or the potato harvester. The algorithm scans images which include clusters of tubers and clods from left to right until it encounters a cluster. Once encountered, a scan around the peripher...

After rice and wheat, Potato (Solanum tuberosum L.) is the third most important food crop worldwide and provides high quality nutrition, especially food energy, vitamin C, potassium, protein and dietary fiber [1,2]. Due to their short production cycle, potatoes provide food faster than cereals or legumes and produce more food calories per hectare, and use less water as compared to either wheat ...

Potato tuber is a high yielding food crop known for its high levels of starch accumulation but only negligible levels of triacylglycerol (TAG). In this study, we evaluated the potential for lipid production in potato tubers by simultaneously introducing three transgenes, including WRINKLED 1 (WRI1), DIACYLGLYCEROL ACYLTRANSFERASE 1 (DGAT1) and OLEOSIN under the transcriptional control of tuber-...

The compartmentation of metabolism in heterotrophic plant tissues is poorly understood due to the lack of data on metabolite distributions and fluxes between subcellular organelles. The main reason for this is the lack of suitable experimental methods with which intracellular metabolism can be measured. Here, we describe a nonaqueous fractionation method that allows the subcellular distribution...

Pueraria mirifica is a tuberous plant enriched with active phytoestrogens. There is no established information about the factors influencing isoflavonoid storage in the tubers. We investigated the tuberous storage of the major isoflavonoids of 1-year-old plants. Four cultivars of P. mirifica were cultivated in the same field trial during the same period to establish a unique plant age and diffe...

Potato late blight, caused by the oomycete phytopathogen Phytophthora infestans, is a devastating disease found in potato-growing regions worldwide. Long-term management strategies to control late blight include the incorporation of host resistance to predominant strains. However, due to rapid genetic changes within pathogen populations, rapid and recurring identification and integration of nov...
