Abstract ELONGATED HYPOCOTYL5( HY5) is a bZIP( leucine zipper) transcription factor. It is an
important regulatory factor promoting photomorphogenesis,and involved in regulation of plant root system growth,
hypocotyl elongation after seed germination,and pigment biosynthesis,etc. development procedure by light and
hormones,etc. factors. HY5 can promote the transportation of photosynthetic products in plants above ground.
It can also be a signal molecule to move from above ground part to root system,promoting the absorption and
transportation of nitrates in root system,and maintaining carbon and nitrogen balance in plants,thus achieving
the signal exchange between aboveground and underground parts of the plant. This paper reviews the research
progress made in recent years about HY5 regulatory effects in plant photomorphogenesis,endogenous hormone
signal transduction,nitrogen metabolism,and carbon-nitrogen balance,etc.
