A prostaglandina F2a (PGF) é uma substância biologicamente potente com diversas aplicações no controle da reprodução. Em bovinos, é usada por sua propriedade luteolítica, indutora dee por melhorar o ambiente uterino para o desenvolvimento da concepção inicial. Estudos recentes suportam a hipótese que a PGF, durante a fase de crescimento tardia do folículo dominante, pode resultar na ovulação, por um mecanismo independente de luteólise, ou seja, na ausência de um CL. O uso da PGF reduz os custos dos protocolos e traz uma nova alternativa especialmente em países onde o uso de estradiol é proibida. |

Drought cause serious yield losses in soybean (Glycine max), roots being the first plant organ to detect the water- stress signals triggering defense mechanisms. We used two drought induction systems to identify genes differentially expressed in the roots of the drought-tolerant soybean cultivar MG/BR46 (Conquista) and characterize their expression levels during water deficit. Soybean plants grown in nutrient solution hydroponically and in sand-pots were submitted to water stress and gene expression analysis was conducted using the differential display (DD) and real time polymerase chain reaction (PCR) techniques. Three differentially expressed mRNA transcripts showed homology to the Antirrhinum majus basic helix-loop-helix transcription factor bHLH, the Arabidopsis thaliana phosphatidylinositol transfer protein PITP and the auxin-independent growth regulator 1 (axi 1). The hydroponic experiments showed that after 100 min outside the nutrient solution photosynthesis completely stopped, stomata closed and leaf temperature rose. Both stress induction treatments produced significant decrease in the mitotic indices of root cells. Axi 1, PITP and bHLH were not only differentially expressed during dehydration in the hydroponics experiments but also during induced drought in the pot experiments. Although, there were differences between the two sets of experiments in the time at which up or down regulation occurred, the expression pattern of all three transcripts was related. Similar gene expression and cytological analysis results occurred in both systems, suggesting that hydroponics could be used to simulate drought detection by roots growing in soil and thus facilitate rapid and easy root sampling.
