| The N-linked glycosylation of secretory and membrane proteins is the most complex posttranslational modification known to occur in eukaryotic cells. It has been shown to play critical roles in modulating protein function. Although this important biological process has been extensively studied in mammals, much less is known about this biosynthetic pathway in plants. The enzymes involved in plant N-glycan biosynthesis and processing are still not well defined and the mechanism of their genetic regulation is almost completely unknown. In this paper we describe our first attempt to understand the N-linked glycosylation mechanism in a plant species by using the data generated by the Sugarcane Expressed Sequence Tag (SUCEST) project. The SUCEST database was... |

| Abscisic acid (ABA) regulates stress responses in plants, and genomic tools can help us to understand the mechanisms involved in that process. FAPESP, a Brazilian research foundation, in association with four private forestry companies, has established the FORESTs database (<A HREF="https://forests.esalq.usp.br">https://forests.esalq.usp.br</A>). A search was carried out in the Eucalyptus expressed sequence tag database to find ESTs involved with 9-cis epoxycarotenoid dioxygenase (NCED), the regulatory enzyme for ABA biosynthesis, using the basic local BLAST alignment tool. We found four clusters (EGEZLV2206B11.g, EGJMWD2252H08.g, EGBFRT3107F10.g, and EGEQFB1200H10.g), which represent similar sequences of the gene that produces NCED. Data... |

| Os vírus pertencentes ao subgrupo do Sugarcane mosaic virus (SCMV, gênero Potyvirus, família Potyviridae) infectam e causam mosaico em diferentes espécies botânicas da subfamília Panicoideae (família Poaceae), porém apenas o SCMV e o Sorghum mosaic virus (SrMV) infectam naturalmente cana-de-açúcar. No Brasil, a espécie SCMV parece ser o único agente causal da doença. Embora a maioria das variedades comerciais de cana-de-açúcar seja considerada resistente ou tolerante ao SCMV, relatos de incidência de mosaico em tais variedades têm ocorrido no campo. Amostras com sintomas, de diversos clones e variedades, foram coletadas em campos experimentais e comerciais de cana-de-açúcar. Dentre as variedades, a RB72-454, uma das mais plantadas no país e considerada... |
