Studies on the presence of adenosine cyclic 3':5'-monophosphate in oat coleoptiles.

abstract：:Strigolactones, recently discovered as plant hormones, regulate the development of different plant parts. In the root, they regulate root architecture and affect root hair length and density. Their biosynthesis and exudation increase under low phosphate levels, and they are associated with root responses to these cond...
