BACKGROUND Calligonum polygonoides L. subsp. comosum (L'Hér.) Sosk. is a plant species belonging to family Polygonaceae. Susceptibility to threaten, presence of various chemical constituents, and many medicinal effects reported for this plant in addition to rareness of in vitro culture studies have fuelled the need for its micropropagation and phytochemical investigations of the produced cultur...

BACKGROUND Blood lead levels (BLLs) have been shown to increase during periods of high bone turnover such as pregnancy and menopause. OBJECTIVES We examined the associations between bone turnover and micronutrient intake with BLLs in women 20-85 years of age (n = 2,671) participating in the National Health and Nutrition Examination Survey, 1999-2002. METHODS Serum bone-specific alkaline pho...

Benzo[a]pyrene (BaP) is a ubiquitous, potent, and complete carcinogen resulting from incomplete organic combustion. BaP can form DNA adducts but other mechanisms may play a role in toxicity. We used a functional toxicology approach in S. cerevisiae to assess the genetic requirements for cellular resistance to BaP. In addition, we examined translational activities of key genes involved in variou...

The plants of Hedysarum alpinum L. in the North are characterized by a long pregenerative period, laboriousness seed propagation, low field germination seeds, rare self-sowing, and impossibility vegetative propagation. In connection with this, it seemed relevant to introduce this species (included Red Book Komi Republic) into aseptic culture preserve maintain gene pool, as well further develop ...

ABSTRACT Physalis ixocarpa Brot. ex Horm. is considered the most economically important species of genus. Tissue culture pointed out as a strategy for its propagation, but researches indicate that in vitro responses are genotype-dependent. This study aimed to evaluate morphogenesis P. green and purple varieties, view massive propagation species. The morphogenic capacity explants cotyledonary no...

Piper betle L., a dioecious shade-loving perennial climber is one of the important Pan-Asiatic plants. More than hundred landraces having marked variation in leaf chlorophyll (Chl) content are in cultivation in India. In this study, role of chlorophyllase (Chlase) in Chl homeostasis and post-harvest breakdown was investigated in two contrasting P. betle landraces Kapoori Vellaikodi (KV) with li...

Physiological characteristics of in vitro and field cultivated Leucojum aestivum l. Plants stanilova m. summary. A living collection of Leucojum aestivum L. (Amaryllidaceae) was established at the Institute of Botany, Sofia, in 2001. In vitro cultures originating from a single mother bulb have been maintained since 2003 on MS-based agar-solidified medium supplemented with 30 g L-1 sucrose, 2 mg...

background aloe vera l. is an important pharmaceutical plant from which several medicinal and cosmetic compounds are extracted. aloe is naturally propagated through offset, which is a slow and expensive labor cost method with low economical income. objectives in this study, the effect of different media on shoot proliferation of the shoot tip of aloe vera l. was investigated. materials and meth...

lemon balm (melissa officinalis l.) is an herbaceous perennial plant of the lamiaceae family that has a wide edible and medicinal uses. in this research the potential of five different explants (nodal segments, shoot tip, cotyledon, hypocotyl and leaf segments) on ms mediums supplemented with different concentrations of 6-benzylaminopurine (bap) (2.2, 4.4 and 8.8 µm) alone or in combination wit...
