히로카즈 타카하시 교수의 연구실은 식물의 생장과 환경 적응 메커니즘을 중심으로, 특히 뿌리 구조의 유전적 및 세포생물학적 조절, 대사 경로와 호르몬 간의 상호작용에 중점을 두고 있습니다. 주로 에틸렌, 사이토크라닌, 아미노산 대사 등이 관여하는 세포 사멸, 뿌리 형성, 수중 생장 적응 등에 대한 분자 기전을 규명하고 있으며, 식물의 생장 조절을 위한 유전자 및 신호 전달 경로의 기능을 탐구하고 있습니다. 이는 농업의 지속 가능성을 높이기 위한 '두 번째 녹색 혁명'의 핵심 과제인 뿌리 시스템 최적화와도 연결됩니다.

These results suggest that ADH1 is essential for sugar metabolism via glycolysis to ethanol fermentation in both the embryo and endosperm. In the endosperm, energy is presumably needed for synthesis of the amylases and for sucrose synthesis in the endosperm, as well as for sugar transport to the embryo.
As plants cannot relocate, they require effective root systems for water and nutrient uptake. Root development plasticity enables plants to adapt to different environmental conditions. Research on improvements in crop root systems is limited in comparison with that in shoots as the former are difficult to image. Breeding more effective root systems is proposed as the "second green revolution". There are several recent publications on root system architecture (RSA), but the methods used to analyz
Several genes related to cell wall modification and proteolysis are specifically up- or downregulated in cortical cells during lysigenous aerenchyma formation under aerobic conditions with ethylene treatment. The results suggest that ethylene is perceived in stelar cells, cortical cells and outer cell layers in the maize primary root, and that the cortical cell-specific PCD is controlled downstream of ethylene perception through subsequent gene expression, which is partly regulated by ROS, in th
These results indicate that cell division, as well as cell elongation, occur during coleoptile elongation in rice under complete submergence, and that the reduced ATP levels caused by the ADH1 deficiency repress both of them, thereby impairing coleoptile elongation in the rad mutant under submerged conditions.
The results demonstrate that sucrose derived from leaves is essential for AP and phellogen formation in soybean hypocotyls under waterlogged soil conditions. Maintenance of a high sucrose concentration is thus essential for the development of phellogen and AP and the differentiation of phellogen to AP.
These results suggest that iP-type cytokinins, which are locally synthesized in the hypocotyl, contribute to xylem development. The greater xylem development in Dutch cultivars might contribute to the high yield of the tomato.
