Functional identification of the bHLH transcription factor MdSAT1 in the phosphate deficiency response
Pi starvation severely affects the normal growth and development of plants. In this study, MdSAT1 , a Pi-responsive bHLH transcription factor, was isolated from apples. Ectopic expression of MdAST1 in Arabidops is in increased the number of lateral roots and root tips, as well as the transcript levels of genes related to Pi uptake and transport; thus, improving Pi utilization in response to a Pi deficiency. Moreover, ectopic expression of MdSAT1 significantly accelerated flowering and leaf senescence in Arabidopsis under a Pi deficiency. Taken together, the present study provides a basis for an in-depth investigation of the mechanisms of MdSAT1 on apple Pi uptake and utilization as well as plant growth and development.

期刊介绍：
FRUIT GROWING RESEARCH is an international journal, which has been issued under the care of the Research Institute for Fruit Growing Pitesti, Romania. Fruit growing research is an annual journal aimed at disseminating significant research and original papers on genetic resources, breeding of deciduous fruit trees species; fruit sustainable technologies – environment protection; propagation, virology and tissue culture, postharvest, that can be of interest to a wide audience of plant scientists in all areas of fruit growing. An international Editorial Board advises the journal.
