Characterisation of a cytoplasmic male-sterile hybrid line between Lycopersicon peruvianum Mill. ×Lycopersicon pennellii Corr. and its crosses with cultivated tomato

Production of hybrid varieties of vegetable crops is currently a desired breeding goal, due to their remarkable agronomic performance and to the possibility of intellectual property protection. However, efficient hybrid production requires a careful pollination control to guarantee the hybrid nature of F 1 seed. Several technologies ranging from manual emasculation to genetic transformation are used to inhibit pollen production in mother plants. In this review, we examine the principles underlying strategies like genetically determined systems (genic male sterility, cytoplasmic-genic male sterility, self-incompatibility) and other methods (manual emasculation, chemical-hybridizing agents) in different species, considering the benefits and drawbacks of their adoption. Finally, we present the current state of the art for vegetable hybrid seed production.

“…We cloned a cDNA that encodes a GSK from the anthers of Lycopersicon peruvianum, the female parent plant from in the Lycopersicon CMS system (11),. Amino acid comparisons and phylogenetic analysis reveals LpSK6 is highly homologous to two members of the Solanaceae subgroup, and is most likely an ortholog of the NSK6 and PSK6 genes.…”

“…CMS occurs in over 150 plant species with phenotypes that exhibit a lack or malformation of male organs, failure of PMC to undergo meiosis, and/or altered microspore development , abortion of pollen at any stage of development, possession of mature non-functioning pollen , and shortened petals (reviewed in 4,8). In the genus Lycopersicon, arrestment of pollen development in the CMS-pennellii phenotype appears between the tetrad and early microspore stages (11,. In this report we describe the further characterization of LpSK6 in terms of its relationships to the other group III GSKs and its tissue-specific expression.…”

Members of the glycogen synthase kinase 3/SHAGGY-like protein kinase (GSK) family in plants are important regulators of stress response, development, and brassinosteroid signaling, and are highly homologous to animal GSKs. Several of the plant kinases are preferentially expressed during pollen development. We report the characterization of LpSK6, a member of the GSK family from the genus Lycopersicon. LpSK6 shows high sequence homology to members of group III, which contain a putative mitochondrial targeting peptide. LpSK6 is expressed 3 to 5 fold higher in anthers than in roots and stems, and is the first GSK gene isolated from genus Lycopersicon.
