A computer model, SPRINKMOD, was tested with field collected from a simple sprinkler irrigation system in operation. The original data for laterals and the amount and way leakage is considered were modofied to evaluate the model sensitivity. The model predicted the pump station flow rate within 2% and the pump station pressure head within 5% with the original data collected. For this irrigation system, no practical effect was observed in the system operating point by changing the lateral pipe charateristics, lateral leakage amount and distribution, lateral pipe roughness and lateral local loss coefficient for flow past a rise outlet. The amount of leakage had more effect on the model simulation of pressure heads than the way leakage was considered, localized or distributed along the laterals. The use a variable local loss coefficient, K along the 350-m hand-move laterals had a negligible effect on both system operating point and distribution of pressure heads along the laterals. |

Several mechanisms regulating gene expression contribute to restore and reestablish cellular homeostasis so that plants can adapt and survive in adverse situations. MicroRNAs (miRNAs) play roles important in the transcriptional and post-transcriptional regulation of gene expression, emerging as a regulatory molecule key in the responses to plant stress, such as cold, heat, drought, and salt. This work is a comprehensive and large-scale miRNA analysis performed to characterize the miRNA population present in oil palm (Elaeis guineensis Jacq.) exposed to a high level of salt stress, to identify miRNA-putative target genes in the oil palm genome, and to perform an in silico comparison of the expression profile of the miRNAs and their putative target genes.

Our findings provide new insights into the early response of young oil palm plants to salinity stress and confirm an expected preponderant role of transcription factors - such as NF-YA3, HOX32, and GRF1 - in this response. Besides, it points out potential salt-responsive miRNAs and miRNA-putative target genes that one can utilize to develop oil palm plants tolerant to salinity stress.
