Project description:We evaluated the possible mechanisms by which exposure to a sequentially treated pulp and paper mill effluent affects gene expression in the liver of male and female fathead minnows. Sexually mature fathead minnows were exposed to either river water, which served as our control (C), 10% untreated kraft effluent (UTK), 25% treated kraft effluent (TK) or 100% final effluent (CMO) from a multiprocess pulp and paper mill for 6 days. A total of 4 treatments. Each exposure aquarium consisted of a 42.1 L column that contained individual 5.3 L chambers. Each chamber contained a FHM breeding pair. A total of 3 biological replicates for male and female FHM per treatment were sent for microarray analysis resulting in a total of 24 arrays run as a reference design with a pooled sample of the 6 river water exposed fish serving as the reference sample..
Project description:Oil palm breeding and seed development have been hindered due to the male parent's incapacity to produce male inflorescence as a source of pollen under normal conditions. On the other hand, a young oil palm plantation has a low pollination rate due to a lack of male flowers. These are the common problem of sex ratio in the oil palm industry. Nevertheless, the regulation of sex ratio in oil palm plants is a complex mechanism and remains an open question until now. Researchers have previously used complete defoliation to induce male inflorescences, but the biological and molecular mechanisms underlying this morphological change have yet to be discovered. Here, we present an RNA-seq dataset from three early stages of an oil palm inflorescence under normal conditions and complete defoliation stress. This transcriptomic dataset is a valuable resource to improve our understanding of sex determination mechanisms in oil palm inflorescence.
