Comprehensive Study of Si-Based Compounds in Selected Plants ( L., L., L.).

This review describes the role of silicon (Si) in plants. Methods of silicon determination and speciation are also reported. The mechanisms of Si uptake by plants, silicon fractions in the soil, and the participation of flora and fauna in the Si cycle in terrestrial ecosystems have been overviewed.

Changes in the Carbohydrate Profile in Common Buckwheat ( Moench) Seedlings Induced by Cold Stress and Dehydration.

Plant species are sensitive to stresses, especially at the seedling stage, and they respond to these conditions by making metabolic changes to counteract the negative effects of this. The objectives of this study were to determine carbohydrate profile in particular organs (roots, hypocotyl, and cotyledons) of common buckwheat seedlings and to verify whether carbohydrate accumulation is similar or not in the organs in response to cold stress and dehydration. Roots, hypocotyl, and cotyledons of common buckwheat seedlings have various saccharide compositions.

Exogenously Applied Cyclitols and Biosynthesized Silver Nanoparticles Affect the Soluble Carbohydrate Profiles of Wheat ( L.) Seedling.

Cyclitols, such as -inositol and its isomers and methyl derivatives (i.e., d--inositol and d-pinitol (3--methyl--inositol)), are classified as osmolytes and osmoprotectants and are significantly involved in plant responses to abiotic stresses, such as drought, salinity and cold.

Jasmonic acid and ethylene are involved in the accumulation of osmotin in germinating tomato seeds.

The expression of SlNP24 encoding osmotin was studied in germinating tomato seeds Solanum lycopersicum L. cv. Moneymaker.

The Healing-Promoting Properties of Selected Cyclitols-A Review.

Introduction: -inositol and its derivatives cyclitols play an important role in the processes of cell regulation, signal transduction, osmoregulation, and ion channel physiology, and are a component of the cell membrane. Free cyclitols present in food or released during the degradation of galactosyl cyclitols by bacteria (in digestive tract) show some physiological benefits.

Aim: The aim of this paper is to present and analyze the documented data about curative and healing properties of cyclitols.

The acquisition of desiccation tolerance in developing Vicia hirsuta seeds coincides with an increase in galactinol synthase expression and soluble α-D-galactosides accumulation.

Galactinol is the galactosyl donor for the biosynthesis of both the raffinose family oligosaccharides (RFOs) and galactosyl cyclitols (Gal-C). Its synthesis by galactinol synthase (GolS, EC 2.4.

Mechanisms of hormonal regulation of endosperm cap-specific gene expression in tomato seeds.

The micropylar region of endosperm in a seed, which is adjacent to the radicle tip, is called the 'endosperm cap', and is specifically activated before radicle emergence. This activation of the endosperm cap is a widespread phenomenon among species and is a prerequisite for the completion of germination. To understand the mechanisms of endosperm cap-specific gene expression in tomato seeds, GeneChip analysis was performed.
