应该注意的是，在硫胺素-吡啶（loxin）培养基中加入烟酸对生长，特别是横向生长的刺激表明烟酸可能对生长产生影响，这不是由于对维生素B6的任何“节约”作用。迄今为止，关于甘氨酸取代吡啶氧还蛋白的数据，关于甘氨酸和烟酸在基础培养基中的协同作用的数据，以及甘氨酸和吡啶氧还蛋白在基础培养基中的协同作用加上硫胺素、吡啶氧还蛋白、烟酸和甘氨酸的数据，证明了维生素B6和甘氨酸或烟酸在所研究的离体根克隆中的联系。这种联系的代谢基础正在通过分析和进一步的营养学研究来检验。
should be noted that the stimulation of growth, particularly of lateral growtth, on the addition of niacin to the thiamin-pyri(loxin medium indicates that niacin may exert an effect on growth which is not due to any "sparing" action on vitamin B6. It is evidlent that the data obtained so far on the replacement of pyridoxin by glycine, on the synergistic effect of glycine plus niacin in basal medium plus glycine and niacin, Ind the synergistic effect of glycine plus l)yridoxin in basal imedium plus thiamin, pyridloxin, niacin, an(d glycine, denmonstrate a connection between vitamin B6 and glycine or niacin in the clone of excise(l tom11ato roots studied here. The metabolic basis of this connection is being examined 1wainalytical and fturther nutritional studies.
