Knowledge about gene expression during sugarcane growth and maturation is limited. A gene discovery programme has been in progress at SASEX since 1994 to identify and analyse genes that are expressed in different sugarcane tissue types and developmental stages. A database of sugarcane gene sequences has been established through the generation of Expressed Sequence Tags (ESTs). This database, co...

During seed maturation and germination, major changes in physiological status, gene expression, and metabolic events take place. Using chlorophyll sorting, osmopriming, and different drying regimes, Brassica oleracea seed lots of different maturity, stress tolerance, and germination behavior were created. Through careful physiological analysis of these seed lots combined with gene expression an...

Abstract Over the past decades, Atlantic salmon ( Salmo salar, Salmonidae) has emerged as a model system for sexual maturation research, owing to high diversity of life history strategies, knowledge trait genetic architecture, and their economic value. The aim this synthesis is summarize current state concerning in salmon, outline gaps, provide roadmap future work. We knowledge: 1) takes place ...

objective: to evaluate the effect of cytoplasm transfer from mature oocytes to germinal vesicle(gv)s on promoting the maturation of cytoplasm of gv at the mrna level. materials and methods: sixty six in vitro fertilization (ivf) operations between june 2012 and november 2013 were included in this study. totally 120 gvs were obtained. normal gvs were categorized into 3 groups (n = 40) randomly: ...

BACKGROUND The hormonal control of oocyte maturation and ovulation as well as the molecular mechanisms of nuclear maturation have been thoroughly studied in fish. In contrast, the other molecular events occurring in the ovary during post-vitellogenesis have received far less attention. METHODS Nylon microarrays displaying 9152 rainbow trout cDNAs were hybridized using RNA samples originating ...

Centrosomes comprise a pair of centrioles surrounded by an amorphous pericentriolar material (PCM). Here, we have performed a microscopy-based genome-wide RNA interference (RNAi) screen in Drosophila cells to identify proteins required for centriole duplication and mitotic PCM recruitment. We analysed 92% of the Drosophila genome (13,059 genes) and identified 32 genes involved in centrosome fun...

UNLABELLED Newborn neurons enter an extended maturation stage, during which they acquire excitability characteristics crucial for development of presynaptic and postsynaptic connectivity. In contrast to earlier specification programs, little is known about the regulatory mechanisms that control neuronal maturation. The Pet-1 ETS (E26 transformation-specific) factor is continuously expressed in ...

Traditionally, the elucidation of genes involved in maturation and aging has been studied in a temporal fashion by examining gene expression at different time points in an organism's life as well as by knocking out, knocking in, and mutating genes thought to be involved. Here, we propose an in silico method to combine clinical electronic medical record (EMR) data and gene expression measurement...

BACKGROUND In the cow, lysophosphatidic acid (LPA) acts as an auto-/paracrine factor, through its receptors LPAR1-4, on oocytes and cumulus cells during in vitro maturation (IVM). The aim of the present work was to determine the effect of LPA during IVM of bovine oocytes on: 1) oocyte maturation; 2) apoptosis of COCs; 3) expression of genes involved in developmental competence and apoptosis in ...

In Arabidopsis, the basic leucine zipper transcription factor ABI5 activates several late embryogenesis-abundant genes, including AtEm1 and AtEm6. However, the expression of many other seed maturation genes is independent of ABI5. We investigated the possibility that ABI5 homologs also participate in the regulation of gene expression during seed maturation. We identified 13 ABI5-related genes i...
