chenopodium glaucum/ニコチン

Flowering of Chenopodium rubrum seedling plants was obtained in continuous light after application of fractions of a partially purified extract from leaves of flowering Maryland Mammoth tobacco (Nicotiana tabacum). The stage of flowal differentiation was dependent on the age of the Chenopodium

Thirty-two weed species common in South Carolina and one cultivar of tobacco were evaluated as hosts of Meloidogyne arenaria race 2 and M. incognita race 3 in the greenhouse. Egg mass production and galling differed (P < 0.05) among weed species. Chenopodium album, Euphorbia maculata, and Vicia

Higher plants express several isoforms of vacuolar and cell wall invertases (CWI), some of which are inactivated by inhibitory proteins at certain stages of plant development. We have purified an apoplasmic inhibitor (INH) of tobacco (Nicotiana tabacum) CWI to homogeneity. Based on sequences from

Betalains are plant pigments primarily produced by plants of the order Caryophyllales. Because betalain possesses anti-inflammatory and anticancer activities, it may be useful as a pharmaceutical agent and dietary supplement. Recent studies have identified the genes involved in the betalain

Rubus ellipticus is a perennial shrub occurring in natural vegetation of the temperate and subtropical Himalayas. For several years, plants of R. ellipticus in and around the Institute of Himalayan Bioresource Technology in Palampur were seen with mild mosaic and chlorotic symptoms on leaves

Adenylate kinase (ATP:AMP transphosphorylase) is a key enzyme in energy metabolism. The activity of its isoforms is subjected to multiple regulations. It is shown here that a specific fraction consisting of all adenylate kinase isoforms from tobacco leaves and tissue cultures does not bind to the

Antiviral proteins (AVPs) named CAP-I and CAP-II purified from the leaves of Chenopodium album cv Pusa Bathua-1 induced systemic resistance against tobacco mosaic virus (TMV) and sunnhemp rosette virus (SRV) in both hypersensitive as well as systemic hosts. An increased accumulation of two

We have characterized a novel type I ribosome-inactivating protein (CAP30) from the leaves of Chenopodium album. Purified native CAP30 depurinated the ribosomes of Chenopodium, tomato, and tobacco leaves in vitro. To further characterize this protein, cDNA clones were isolated from a leaf cDNA

The ultrastructure of cells of the vegetative shoot apices is described for Chenopodium album, Kalanchoë blossfeldiana and K. laxiflora, Bryophyllum daigremontianum, Nicotiana rustica, and N. tabacum (Maryland Mammoth), and Ginkgo biloba. A less intensive study was made of the last three listed. The

Leaf discs of dark-adapted tobacco plants were excited by 2 flashes and kept in darkness at 20 degrees C for various time periods, then thermoluminescence emission was recorded without freezing the sample. The B band at 30 degrees C decreased with a half-time t1/2 approximately 1 min and the AG band

Gerbera jamesonii (family Asteraceae) is a popular perennial ornamental cut flower and potted plant with considerable economic importance. In a survey of gerbera grown in floriculture fields at the Institute of Himalayan Bioresource Technology (IHBT), Palampur and nearby nurseries, color break

Pelargonium zonate spot virus (PZSV) was first isolated from tomato in southern Italy in 1982 (1) and later was also reported from Spain (3) and France (2). Infected tomato plants showed stunting, malformation, yellow rings and line patterns on the leaves, and concentric chlorotic ringspots on the
