보행 종료(gait termination)는 인간의 보행개시(gait initiation)나 율동성 보행(rhythmical walking)에 비해 관심을 적게 받고 있다. 파킨슨 환자들이 보행종료와 방향전환 시 가지는 어려움은 이들 환자들이 보행 시 넘어지게 되는 노출 요인으로 보고되어져 왔다. 보행종료에 대한 기전의 이해는 효과적으로 걸음을 멈추지 못해 넘어지게 되는 위험요인을 가진 사람들에게 적용되어질 수 있다. 이 논문에서 우리는 보행종료에 대한

Soybean [Glycine max. (L.) Merr] is one of the most important legumes in the world. However, soybean varieties are sensitive to flooding stress and their seed yields are substantially reduced in response to the flooding stress. 192 soybean germplasm collection was screened to identify flooding tolerant germplasm at an early vegetative growth stage (V1). Soybean plants at V1 stage were waterlogged for 4 to 10 days. To evaluate flooding tolerance, survival rate were investigated as a time dependent manner. Jangbaegkong, Danbaegkong, Sowonkong, Socheong2 and Suwon269 showed flooding tolerance, while Shillog, T201, T181, NTS1116 and HP-963 showed flooding sensitivity. We also investigated effects of flooding stress on soybean morphology. The adventitious root development was greatly increased in flooding tolerant plants compared to it in flooding sensitive plants. In addition, root length and root number were analyzed. The significant reduction of root length and root number was observed in flooding sensitive plants. Thus, these results indicate that the morphological changes in roots are important for acclimation to flooding stress. Taken together, the relationship between the morphological changes in the roots and flooding tolerance may be useful in selecting a flooding tolerant soybean germplasm.
