β¦ Synopsis
A full-length cDNA clone encoding tomato (Lycopersicon esculentum Mill.) 5-aminolevulinic acid dehydratase (ALAD) was isolated and characterized. The primary structure predicts a 430-amino acid precursor which comprises a 41.7 kDa, 388-amino acid mature protein and a 47-amino acid transit sequence. The tomato primary sequence shows extensive homology to those of pea and spinach. Southern analysis indicated that 1 to 2 copies of the ALAD gene are present in the tomato genome. Northern blot analysis shows differential expression in various tomato organs, and constitutive developmental expression in tomato fruits.

A cDNA encoding an RNA-binding protein (ribonucleoprotein or RNP) was isolated from a tobacco (Nicotiana sylvestris) cDNA library. The predicted protein (termed RGP-2) is 259 amino acids in length and consists of an N-terminal sequence of 39 amino acids, a consensus sequence type RNA-binding domain
