The plant cell wall

Journal of Integrative Plant Biology 2015年第4期57卷 328-329页

作者： Kurt Fagerstedt anna Karkonen Department of Biosciences Division of Plant Biology University of Helsinki Department of Agricultural Sciences University of Helsinki

Research on the many aspects of the plant cell wall has experienced reiuvenation during the past few years. This is perhaps mainly due to the commercial interest in the chemical components of the cell wall that have potential for industrial use＂ Cellulose for fibers and together with hemicelluloses for bioethanol, lignin for plastics or biofuel, pectins as gel agents, let alone woody cell wall material for construction or pulp production and for intelligent materials for electronics - the new uses are mindboggling!

Aphasia is an impairment of language use following brain damage. There is no consensual definition of aphasia beyond this general description （Code and Petheram, 2011）. In a more restricted defini- tion, however, aphasia is an impairment of linguistic processing at the phonological, morphological, lexical semantic or syntactic level which is usually caused by lesions of the left cerebral hemisphere. This impairment can affect language reception and expression depending on the various aphasic syndromes （McNeil and Pratt, 2001）. Aphasia results in restrictions in those activities of daily living which rely on communication.

Potassium （K-） is an essential macronutrient for all livingorganisms and large amounts are required for plant growthand development. In many regions of Asia K+-fertilizationhas been neglected and soils have become K+-depleted. K+-deficiency in the field diminishes not only crop productionbut also leads to environmental problems due to inefficientusage and leaching of nitrate. Consequences of K+-defi-ciency on crop production range from decreased biomass,nutritional quality and taste of the crops to inferior harvestand storage properties, as well as increased susceptibilityto disease. Effects of K+-deficiency on plant physiology in-clude decreased photosynthetic rate, impaired tissue alloca-tion of sugars and amino acids, decreased protein synthesis,and lack of control over turgor and gas exchange [1], K+-uptake and its re-distribution within the plant is facilitatedby a plethora of membrane transport proteins displayingan astonishing diversity with respect to their affinity andselectivity for K+, mode and direction of transport, tissuespecific expression, membrane localization and regulation[2]. Microarray experiments have shown that in contrastto transporters of other macronutrients - genes encodingK--transporters display surprisingly little responsiveness tothe external nutrient supply [3]. This observation probably

Dear Editor,The problem of age estimation in amphibians and reptiles with annual fluctuations of growth pattern has been considered to be mostly solved since the skeletochronological method was introduced(Kleinenberg and Smirina,1969).This method is based on counting the number of lines of arrested growth(LAGs)—cyclical growth marks that are usually formed annually and characterized by different optical aspects within the tubular bones.
