Cellular compartmentation of Zn in the leaves of the hyperaccu-mulator Thlaspi caerulescens was investigated using energy-dispersive x-ray microanalysis and single-cell sap extraction. Energy-dispersive x-ray microanalysis of frozen, hydrated leaf tissues showed greatly enhanced Zn accumulation in the epidermis compared with the mesophyll cells. The(More)
Transforming growth factor-alpha (TGF-alpha), previously identified as a major member of the epidermal growth factor (EGF) family of growth factors, plays a role in proliferation, differentiation, and survival of neuronal and glial precursors and is implicated in development of the nervous system. However, its roles in nerve injury-induced responses remain(More)
OsAMT is a high-affinity ammonium transporter responsible for NH 4 + uptake by rice plants. To investigate the expression patterns of OsAMT in different genotypes in relation to nitrogen accumulation, we measured the expression of OsAMT1.1, OsAMT1.2, and OsAMT1.3 using Real-Time PCR (RT-PCR) in GD (higher N accumulation) and NG (lower N accumulation)(More)
