The bean weevil, Acanthoscelides obtectus Say, causes severe post-harvest losses in the common bean,Phaseolus vulgaris L. The control of these insects is either non-existent or relies heavily on the use of con-ventional insecticides, which increase the risks associated with pest resistance, hazards to human healthand environmental contamination. Protecting grains with alternative chemical control options that allevi-ate the concerns outlined above are urgently needed, and essential oils of plants have been presented as asuitable alternative to fill this void. Therefore, this investigation evaluated the non-fumigant applicationsof clove, Syzygium aromaticum L., and cinnamon, Cinnamomum zeylanicum L., essential oils adequatelycontrol A. obtectus on common beans. The oils were tested for insecticidal (lethal toxicities, disturbanceson reproductive traits and persistence of action) and repellent activities. Both oil types showed similartoxicity (clove LD = 43.6 L/kg beans; cinnamon LD50= 46.8 L/kg beans), steadily decreased the growthrate of A. obtectus in a dose-dependent manner, and similarly lost their insecticidal activity over the time.Additionally, the clove oil delayed bean weevil emergence, whereas cinnamon oil repelled the bean wee-vil. These results indicate clove and cinnamon essential oils as desirable tools for protecting stored beansagainst A. obtectus in small storage facilities, promoting environmentally friendly pest control strategies. |

Abscisic acid-responsive element binding protein (AREB1) is a basic domain/leucine zipper transcription factor that binds to the abscisic acid (ABA)-responsive element motif in the promoterWater deficit response in GM soybeans with (AtAREB1^QT) region of ABA-inducible genes. Because AREB1 is not sufficient to direct the expression of downstream genes under non-stress conditions, an activated form of AREB1 (AtAREB1^QT) was created. Several reports claim that plants overexpressing AREB1 or AREB1ΔQT show improveddrought tolerance. In our studies, soybean plants overexpressing (AtAREB1^QT) were characterized molecularly, and the phenotype and drought response of three lines were accessed under greenhouse conditions. Under conditions of water deficit, the transformed plants presented a higher survival rate (100%) than those of their isoline, cultivar BR 16 (40%). Moreover, the transformed plants displayed better water use efficiency and had a higher number of leaves than their isoline. Because the transgenic plants had higher stomatal conductance than its isoline under well-watered conditions, it was suggested that the enhanced drought response of (AtAREB1^QT) soybean plants might not be associated with altered transpiration rates mediated by ABA-dependent stomatal closure. However, it is possible that the smaller leaf area of the transgenic plants reduced their transpiration and water use, causing delayed stressonset. The difference in the degree of wilting and percentage of survival between the 35S-(AtAREB1^QT) and wildtype plants may also be related to the regulation of genes that protect against dehydration because metabolic impairment of photosynthesis, deduced by an increasing internal CO2 concentration, was not observed in the transgenic plants.
