Unique miRNome during anthesis in drought-tolerant indica rice var. Nagina 22.

abstract：:The phloem is an important conduit for the transport of signaling molecules including RNA. Phloem sap has served as a source of RNA to profile uncontaminated phloem transcriptomes but its collection is difficult in many species. Laser capture microdissection techniques offer a valuable alternative for isolating RNA fr...
