Microarray analysis was used to identify candidate genes that are involved in the formation of secondary cell walls and hydroxycinnamoyl-arabinoxylan (AX) in rice. In order to identify genes involved in secondary cell wall formation, gene expression was compared between wild-type whole internodes that contain cells with thickened secondary cell walls, such as vascular and cortical fiber cells, ...

This study investigated the chemical composition and ruminal degradability of corn stover in three maize-planting regions in Qiqihaer, Heilongjiang Province, China. The whole stover was separated into seven morphological fractions, i.e., leaf blade, leaf sheath, stem rind, stem pith, stem node, ear husk, and corn tassel. The assessment of nutritive value of corn stover and its fractions was per...

The insecticidal and antifeedant activity of extracts derived from different parts of the mangrove tree Rhizophora mucronata (Rhizophoraceae) Lam. is reported. The 70% ethanol extracts of leaves, bark, stem wood and pith were tested for toxicity against adults of the desert locust Schistocerca gregaria (Forskal), the 2 instar larvae of Aedes aegypti (L.) and the 1 instar larvae of the brine shr...

This paper reports the application of the Categorical Perception Paradigm (CP) to a pith height contrast in Majorcan Catalan. The first hypothesis is that pitch height is the primary perceptual cue in distinguishing yes-no questions from wh-questions in Majorcan Catalan. The second hypothesis predicts that, as in previous studies, the application of the CP involves the presence of order of pres...

Due to an increasing demand for environmentally sustainable products, miscanthus and maize stover represent interesting lignocellulosic resources conversion into biofuels biomaterials. The overall purpose was compare regarding cell-wall composition stem anatomy bioethanol polymer composites using partial least squares regressions. For each of the two crops, six contrasted genotypes were cultiva...

Natural thermal insulation materials developed from renewable crop by-products and natural binders are analysed in terms of their thermal degradation and fire behaviour. A pyrolysis combustion flow calorimetre (PCFC) is used to characterise some kinds of crop by-products, including rice husk, corn pith and barley straw. This technique is complemented with a TG analysis. Six thermal insulation m...

The composition of lipophilic extractives in the cortex and pith of elephant grass ( Pennisetum purpureum Schumach.) stems was thoroughly studied by gas chromatography-mass spectrometry. The predominant compounds were fatty acids followed by sterols (in free and conjugated forms as esters and glycosides). Other steroid compounds, as steroid hydrocarbons and ketones, were also present. Addition...

the major aim of this study was to compare the morphology and activity of rumen protozoa of khuzestan water buffalo and holstein cow using in vitro digestibility and gas production parameters of steam treated sugarcane pith. rumen fluid obtained from two buffalo and cow steers fed the same diet, 30:70 concentrate: forage. to separate rumen protozoa, antibiotic solution and fungicides were added...
