متن کاملPhosphate availability regulates root system architecture in Arabidopsis.
Plant root systems are highly plastic in their development and can adapt their architecture in response to the prevailing environmental conditions. One important parameter is the availability of phosphate, which is highly immobile in soil such that the arrangement of roots within the soil will profoundly affect the ability of the plant to acquire this essential nutrient. Consistent with this, t...
متن کاملA role for auxin redistribution in the responses of the root system architecture to phosphate starvation in Arabidopsis.
The changes in root system architecture (RSA) triggered by phosphate (P) deprivation were studied in Arabidopsis (Arabidopsis thaliana) plants grown for 14 d on 1 mM or 3 microM P. Two different temporal phases were observed in the response of RSA to low P. First, lateral root (LR) development was promoted between days 7 and 11 after germination, but, after day 11, all root growth parameters we...
متن کاملPhosphate starvation root architecture and anthocyanin accumulation responses are modulated by the gibberellin-DELLA signaling pathway in Arabidopsis.
Phosphate (Pi) is a macronutrient that is essential for plant growth and development. However, the low mobility of Pi impedes uptake, thus reducing availability. Accordingly, plants have developed physiological strategies to cope with low Pi availability. Here, we report that the characteristic Arabidopsis thaliana Pi starvation responses are in part dependent on the activity of the nuclear gro...
متن کاملCapturing Arabidopsis root architecture dynamics with ROOT-FIT reveals diversity in responses to salinity.
The plant root is the first organ to encounter salinity stress, but the effect of salinity on root system architecture (RSA) remains elusive. Both the reduction in main root (MR) elongation and the redistribution of the root mass between MRs and lateral roots (LRs) are likely to play crucial roles in water extraction efficiency and ion exclusion. To establish which RSA parameters are responsive...
