The full-length cDNA of a presumed glycine-rich ribonucleic acid (RNA) binding protein (ThGRP1) gene was isolated from a cDNA library of Tamarix hispida leaves. The ThGRP1 gene with 800 bp in length contains 432-base pair (bp) open reading frame (ORF) and encodes a 143-amino-acid polypeptide with a predicted molecular weight of 14.95 kDa and pI of 5.36. Expression of ThGRP1 in roots, stems and leaves of T. hispida with PEG, NaCl, NaHCO3 or CdCl2 treatments was studied using real-time PCR. The results showed that ThGRP1 can be induced by these stresses. Especially, the expression of ThGRP1 in roots of T. hispida was induced under all stresses at 6, 12, 24, 48 and 72 h.

花发育是一个复杂的形态建成过程,了解林木花发育分子机理对实现林木的遗传调控具有重要意义。本文综述林木成花的分子机制的研究进展和以转基因等技术定向调控林木及木本经济作物生殖生长的实践案例,并对成花调节在林木育种中的应用前景进行展望。
