“…For example root systems that have increased ratios of surface area to volume will explore a larger volume of soil (Lynch 1995). In legumes (Ardourel et al 1994;Miller et al 1997;Pingret et al 1998;Schultze and Kondorosi 1998;Abdelgani et al 1999;Gressent et al 1999), tomato and pepper (Kim et al 1997;Olsen et al 1999), and alfalfa (Medicago sativa L.) (Van Rhijn et al 1997), root hair growth and thus nutrient uptake can be stimulated and enhanced by Rhizobium bacteria secretions such as lipochito-oligosaccharides or nodulation factors, and the increased activity of extracellular phosphomonoesterases released by this bacteria to the roots for P (Asmar and Gissel-Nielsen 1997;Van Rhijn et al 1997) For personal use only. 1998).…”

“…In these plants the hyphae play an important role in the acquisition of P for the plant (Van Rhijn et al 1997). This symbiosis is founded on the mutual exchange of C from the plant in return for P in roots and other mineral nutrients from the fungus (Asmar and Gissel-Nielsen 1997;Van Rhijn et al 1997;Kim et al 1997). Influx of P in roots colonized by this fungus can be three to five times higher than in non-mycorrhizal roots (Van Rhijn et al 1997;Kim et al 1997).…”

“…Influx of P in roots colonized by this fungus can be three to five times higher than in non-mycorrhizal roots (Van Rhijn et al 1997;Kim et al 1997). In addition, as much as 20% of a plant's photosynthate can be released from the roots into the soil (Asmar and Gissel-Nielsen 1997;Estabrook and Yoder 1998). In tomato roots, N and P uptake as well as plant size increase by the interaction between phosphate-solubilizing bacteria and arbuscular mycorrhizae (Kim et al 1997).…”

Liptay, A. and Arevalo, A. E. 2000. Plant mineral accumulation, use and transport during the life cycle of plants: A review. Can. J. Plant Sci. 80: [29][30][31][32][33][34][35][36][37][38]. Minerals accumulated during each stage of plant development are important, especially for the initial portion of subsequent stages of growth. For example, minerals acquired during seed ontogeny are largely responsible for the earliest stage of seedling growth. Without these minerals, seedling development would be arrested or impossible. Thus, even though the amount of minerals may be relatively small in the seed, their presence is absolutely essential. Similarly, although the mineral nutrient content of a seedling used as a transplant in establishing a crop in the field may seem rather minuscule, the importance to the initiation of development of the successive stage of growth is critical. Moreover, seedling-mineral content, plant performance and seed production can be improved by the selection of optimal cultural practices. This review examines acquisition, content and use of minerals in the various stages of plant development and growth as well as agricultural approaches to enhance mineral accumulation.Key words: Nutrient uptake, field crop establishment, seed mineral content, seed yield, crop growth.Liptay, A. et Arevalo, A. E. 2000. Accumulation, utilisation et transport des minéraux durant le cycle biologique des plantes. Mise au point bibliographique. Can. J. Plant Sci. 80: 29-38. Les minéraux absorbés à chaque stade de croissance de la plante sont importants, en particulier pour la portion initiale de chaque stade ultérieur. Ainsi par exemple, les minéraux absorbés durant l'ontogénie de la graine joueront un rôle déterminant dans les premiers de la croissance de la plantule. Sans eux, celles-ci seraient entravées ou impossibles. Donc même si les quantités absorbées dans la graine sont dans certains cas relativement petites, leur importance n'en demeure pas moins essentielle. De même, si la teneur en éléments nutritifs minéraux dans le jeune plant destiné à être repiqué au champ peut paraître infime, leur présence jouera un rôle critique dans l'initiation de chacun des stades de croissance successifs. D'autre part, il est possible, en adoptant les pratiques culturales optimales d'améliorer la teneur en minéraux du jeune plant et avec elle les performances de la plante et sa production semencière. La revue bibliographique porte sur l'acquisition, les concentrations et l'utilisation des minéraux aux divers stades de croissance et de différenciation, de même que sur les moyens agronomiques de stimuler cette accumulation. Mots clés:Absorption des éléments nutritifs, installation en pleine terre, teneur minérale de la graine, rendement semencier, croissance végétaleCrop production and seedling performance in the field are the result of an adequate supply, distribution and accumulation of minerals, especially during seed formation. For example, minerals are collected at each stage of plant development in preparation for futu...

“…Phosphomonoesterases are important enzymes involved in the P cycle of soil and aquatic environments. Acid phosphomonoesterase (APM) is produced in rhizosphere and bulk soil by various living organisms including bacteria, protozoa, mycorrhizal fungi, and saprophytic fungi, as well as in the form of plant-root exudates (Rejšek, 1991;Asmar and Gissel-Nielsen, 1997;George et al, 2008;Rejšek et al, 2012). They are also transferred to the soil environment along with soil micro-organisms and roots of higher plants.…”

MAROSZ KAREL, VRANOVÁ VALERIE, REJŠEK KLEMENT: Development of biochemical properties in anthropic soil (the study at Třinec-Jahodná plot). Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2013, LXI, No. 1, pp. 137-145 The properties of the anthropic soils formed at the sludge bed "Třinec-Jahodná". The sludge bed came from a long-time depositing of fl y-ash and slag layers. Therefore, the anthropic soil properties obtained their features by both a character of layered substrate and a management of the local land reclamation. The paper presented deals with the rate of an intensity of biological and biochemical soil processes in charge of the fulfi lment of plant nourishment demands, and the time viewpoints focusing on the local soil development. The set of enzymatic and biological measurements were chosen for treatments of soil bodies sampled throughout [2007][2008]. The study plots inside the sludge bed and the control plot were sampled; the properties of particular horizons were studied. The results proved that the twenty-year-development of soil bodies made the proper conditions for plant nutrition. The positive statement, nevertheless, is directly linked to the presence of trees and shrubs. The vegetation seems to be one of the very crucial factors for a status of the site and maintenance of soil productivity: it aff ects temperature amplitudes, sensitivity to erosion, a redistribution of soil water, and a humic compounds accumulation. The statistical analyses showed signifi cantly diff ering results on the study plots with a shorter development and a lower rate of vegetational cover.

“…Acid phosphomonoesterase (APM) in soil is located in diff erent compartments. These include soil and its diff erent fractions, plant roots and mycorrhizal fungi (Burns et al, 1972;McElhinney and Mitchell, 1993;Asmar and Gissel-Nielsen, 1997;Tamás et al, 2008). In these compartments, APM may occur intracellular or extracellular.…”

HOLÍK, L., DUNDEK, P., FORMÁNEK, P., REJŠEK, K., VRANOVÁ, V.: Proportion of root-derived acid phosphomonoesterase in total soil acid phosphomonoesterase in diff erent forests. Acta univ. agric. et silvic. Mendel. Brun., 2011, LIX, No. 3, pp. 55-58 Enzyme acid phosphomonoesterase (APM) plays an important role in phosphorus mineralization in diff erent type of terrestrial ecosystems. This enzyme is of great agronomic signifi cance because it hydrolyses organic phosphorus to diff erent forms of inorganic phosphorus which are assimilable by plants. APM may also indicate changes in the quantity and quality of phosphorylated substrates in soil and is a good indicator of its biological state as well as presence of pollutants. APM may be produced by plant roots and soil microorganisms and both of these sources may play diff erent role in phosphorus mineralization in diff erent ecosystems. The aim of this work was determine acid phosphomonoesterase (APM) activity location in soil of diff erent forest ecosystems. The APM activity location determination was performed on the basis of root-derived and soil-derived APM and expression of proportion of those root-derived in total soil APM up to 13 cm depth. The results of this preliminary study showed that root-derived APM formed 21-34 % of total soil APM in pine and oak forest.acid phosphomonoesterase, soil, forests, roots Extracellular phosphomonoesterases (orthophosphoric monoester phosphohydrolases) catalyze hydrolysis of a variety of organic phosphomonoesters and are therefore important in soil organic P mineralization and plant nutrition. Acid phosphomonoesterase (APM) in soil is located in diff erent compartments. These include soil and its diff erent fractions, plant roots and mycorrhizal fungi (Burns et al
