Expression And Activity

Plants contain multiple forms of catalase (CAT) and their specific functions remain uncertain. We cloned two potato cDNAs corresponding to CAT1 and CAT2 genes, analysed their phylogenetic relationship, and studied their expression and activity in different organs to gain clues to their functions. Phylogenetic trees and the alignment of CAT cDNA sequences provided evidence that CAT1 and CAT2 genes have high identity to catalases of other solanaceous species, but are not phylogenetically closely related to one another, which contradicts the phylogenetic closeness ascribed to these genes. Northern blot analyses revealed that expression of CAT genes is controlled by leaf developmental phase. CAT2 expression was higher in both very young and senescent leaves, whereas CAT1 mRNA accumulated mainly in mature leaf, where the lowest CAT2 expression occurred. CAT1 and CAT2 are also differentially expressed in root, sprout and petal. Expression and activity patterns are consistent with different physiological roles for CAT1 and CAT2 isoforms. CAT1 is considered to be associated with photorespiration whereas CAT2 would fulfill physiological roles unrelated to this process. CAT2 appears to be a multifunctional isoform, associated with glyoxysomal activity in leaf senescence, other processes in non-photosynthetic organs and defence, functions that in other solanaceous species are fulfilled by two different isoforms.

Susceptibility Status

A necrotrophic reaction in leaf discs of a wide range of Nicotiana and other Solanaceous and non-Solanaceous species following infection by Peronospora tabacina Adam is described.With a few exceptions, species resistant to the pathogen developed water-soaking or gave no reaction, whereas susceptible species showed necroses affecting 60-100% of the leaf disc area. The degree if necrotrophic reaction is related to the resistance-susceptibility status of Nicotiana species, and it may be extended to detect susceptibility to the pathogen in Petunia, Capsicum, Lycopersicon, Hyoscyamus, Schizanthus, and other genera related ti Nicotiana.

Genetically stable artificial autotetraploids with over 90% seed set were obtained by colchicine treatment of the solanaceous species Hyoscyamus niger L. (4x = 68). The tetraploids were vigorous and had earlier been shown to yield considerably more tropane alkaloid per individual than the source diploids. The tetraploids had high bivalent frequencies at meiosis, and high fertility as a result of the formation of genetically balanced gametes. There was a systematic and significant decrease in quadrivalent frequency and an increase in bivalent frequency in three subsequent generations tested (C0, C1, C2). Possible causes of high bivalent frequency are discussed. Seed fertility can probably be increased in advanced generations by further selection for fertility and maximization of heterozygosity.Key words: Hyoscyamus niger, autotetraploid, meiosis, bivalents, fertility, selection.
