“…2b, curve 4) and the statistically significant increase in δl after 2 h treatment of roots with α naphthyl acetate (Fig. 4c) reflect, as noted above, the phenomenon of "acid growth" related to the apoplast acidification [18]. The subsequent decrease of δl below the control level, both in the presence of 10 mM NH 4 Cl and under the action of α naphthyl acetate, is probably mediated by the Ca 2+ dependent disassembling of CMT.…”

“…1, curve 6), and this growth reduction was accompanied by the decrease in δl, L p , and δD/D to 60-70% of the control values (table). In this case, changes in L p and δD/D parameters were likely caused by the apoplast acidification through the mechanism comprising the protonation of anionic sites in cell walls and the plas malemmal outer side, the hardening of cell wall matrix, and the blockage of water channels [17,18]. The mechanism of δl reduction in the presence of N is apparently related to the increase in concentration, as it occurs upon ROS accumulation.…”

“…Отсюда следует, что способность растений к бесперебойному поглощению воды связана с активацией роста их корней (10). Оказалось, что недостаток почвенной влаги обусловливает усиление роста корней, увеличивая тем самым возможность поглощения воды (33). Таким образом, способность корней к непрерывному росту имеет определяющую роль в адаптации к дефициту воды, поскольку благодаря именно этому процессу растение получает ее в необходимом количестве (34).…”
