Cloning and characterization of a second form of the rice adenine phosphoribosyl transferase gene (OsAPT2) and its association with TGMS.

A rice gene, OsAPT2, which encodes a putative adenine phosphoribosyl transferase (APRT), was cloned and characterized. Analysis of the cDNA and genomic sequences revealed seven exons and six introns in the OsAPT2. The deduced amino acid sequence of OsAPT2 is highly homologous to those of previously isolated APRTs.

[Construction of expression vector with BG2 gene and its transformation in wheat].

beta-1,3-glucanase(BG2) is one of the pathogensis-related-proteins(PR). Study of these proteins and their related genes is one of the hot points in plant genetic engineering of disease resistance for a long time. In this research, specific primers were designed with the enzyme cleavage site of Spe I in its forward one and Not I site in the backward according to the BG2 gene sequence.

[Inheritance of resistance of southern corn rust in the inbred line Qi319].

Southern corn rust (SCR) is a destructive disease in maize. The inbred line Qi319 is highly resistant to southern corn rust. The inheritance of resistance to southern rust in Qi319 was investigated.
