A cDNA Clone for 5-Aminolevulinic Acid Dehydratase from Tomato (Lycopersicon esculentum Mill.)

A cDNA clone for 5-aminolevulinic acid dehydratase from tomato (Lycopersicon esculentum Mill.).

Nucleotide sequence of a cDNA clone encoding tomato (Lycopersicon esculentum) cysteine proteinase.

When a tomato (Lycopersicon esculentum) leaf cDNA library was screened with a cDNA fragment from a polymerase chain reaction prepared using a degenerate primer mixture that was based on the amino acid sequence of tomato systemin (Pearce et al., 1991), a clone (LCYP-2) was obtained of 1295 bp, not including the 3’-terminal poly(A+) tail (Table I). It is surprising that when sequenced the clone a...

In vitro flowering and fruiting in tomato (Lycopersicon esculentum Mill.)

In vitro flowering and fruiting were induced in plants regenerated from calli of leaf explants of Lycopersicon esculentum var. Pant 11. MS medium supplemented with 2 mg/l BAP displayed the best response followed by MS with 2 mg/l BAP, 1 mg/ l ABA and 0.5 mg/l IAA. Flower buds were developed both directly from callus and regenerated plantlets from leaf explants under 16 h (39.3 μmol m-2s-1) phot...

Tomato (Lycopersicon esculentum) genomic clone homologous to a gene encoding an abscisic acid-induced protein.

The plant hormone ABA is involved in a number of important physiological and developmental processes including the response of vegetative tissues to osmotic stress and fruit ripening (Davies and Mansfield, 1983). We report here the main structural features of a gene termed Asr2 (Table I), homologous to Asrl (standing for ABA, stress, and ripening), whose cDNA has been previously characterized (...

Growth and Physiological Responses of Tomato (lycopersicon Esculentum Mill.) to Simulated Acid Rain

This investigation was undertaken to ascertain the effect of simulated acid rain (SAR) on growth, yield and physiological parameters of tomato. SAR exposure (pH 3.0 and 4.0) caused white-to-tan spots on the abaxial and adaxial surface of tomato leaves. SAR exposure at pH 3.0 and 4.0 significantly suppressed pigment synthesis, shoot and root dry weights and yield of tomato. The effects were more...
