Poplar genes encoding fasciclin‐like arabinogalactan proteins are highly expressed in tension wood

Abstract: Summary Fifteen poplar cDNA encoding fasciclin‐like arabinogalactan proteins (PopFLAs) were finely characterized, whereas the presence of arabinogalactan proteins (AGPs) was globally assessed during wood formation. PopFLAs transcript accumulation was analysed through EST distribution in cDNA libraries, semi‐quantitative RT‐PCR, microarray experiment and Northern blot analysis. Similarly, AGPs contents were globally quantified by rocket electrophoresis. AGPs accumulation was further examined by Western blott… Show more

“…Arabinogalactan proteins are extracellular proteoglycans that appear to have an as yet unexplained role in influencing cell proliferation (Schultz et al, 2000). Arabinogalactans have also been shown to be highly expressed in tension wood in poplar (Lafarguette et al, 2004). Their role there is suggested to be structural and it is highly probable that ozone is causing structural changes to cell wall components either directly or through the formation and action of free radicals (Fry et al, 2001) and thus inducing stress-associated cell wall re-modelling.…”

“…Cuando estas proteínas poseen el dominio fasciclin, se denominan fasciclin tipo arabinogalactano (FLA) (Gaspar et al 2001;Johnson et al 2003). Las AGPs son proteínas ampliamente distribuidas en el reino vegetal y se encuentran principalmente en las paredes celulares, membrana plasmática y en los espacios intracelulares; están implicadas en diversos roles como la diferenciación, el reconocimiento célula-célula, embriogénesis somática y muerte celular programada (Lafarguette et al 2004). De la misma forma, para el dominio fasciclin se ha visto que varias proteínas presentes en la matriz extracelular de la célula con estos dominios muestran una función importante en el desarrollo y adhesión de moléculas (Gaspar et al 2001, Johnson et al 2003.…”

Sin embargo, no existe evidencia experimental que permita dilucidar la función biológica de este tipo de proteínas (Lafarguette et al 2004, MacMillan et al 2010. Lafarguette et al (2004) analizaron los niveles de expresión de genes homólogos codificantes para FLA en cambium y xilema de madera de tensión y opuesta de Populus, pero ninguno de los transcritos de fla fueron detectados en las muestras de la zona cambial.…”
