ABSTRACT The genetic control of eight isozyme loci revealed by starch gel electrophoresis was studied through the analysis of three progenies derived from four tetraploid cultivars of Solanum tuberosum (groups Andigena and Tuberosum). Duplicate gene expression was found in seven (Got-A, Got-B, Pgd-C, Pgi-B, Pgm-A, Pgm-B and Pox-C) isozyme loci. In another isozyme gene (Adh-A), the parental genotypes were not adequate to distinguish between a monogenic or a digenic model of genetic control. Tetrasomic inheritance was demonstrated in four (Got-A, Got-B, Pgd-C and Pgi-B) isozyme loci. In the remaining duplicate genes, the parental genotypes precluded discrimination between disomic or tetrasomic models. Tetrasomic segregations of the chromosomal type were generally found; however, the isozyme phenotypes shown by three descendants from selfing cv. Katahdin indicate the occurrence of chromatid segregations, although aneuploidy cannot be ruled out. Either autoploidy or amphidiploidy with lack of chromosome differentiation between the two diploid ancestors can account for the existence of tetrasomic inheritance in the common potato.

It has been speculated that the rapid tuberization of explanted etiolated stolon nodes of the common potato relates to the osmotic concentration of the medium since this response is speeded by increased sucrose levels up to 12%. This paper demonstrates that the response probably pertains to the energy requirements of the tuberizing explanted stolon and that osmotic concentration is not crucial.

Although the common aphids that infestSolanum tuberosumL. in North America and Europe appear to be the same, different scientific names are used for them on the two continents. This unsatisfactory situation is confusing to both entomologists and virologists and shouId be corrected. This paper presents the preferred scientific names. Only the most important synonyms are discussed.

Solanum Gourlayi

Solanum commersonii Dun. (cmm) is a diploid wild species of potential value for potato breeding. Ploidy level manipulations are necessary to cross this species with the common potato. This could be achieved by the use of "bridge" species and sexual polyploidization in which 2n gametes are involved. Eight introductions of cmm were screened for production of (i) diplandroids, through cytological observations confirmed by controlled 4x Solanum acaule Bitt. (acl) × 2x cmm crosses, and (ii) diplogynoids, by controlled 2x cmm × 2x Solanum gourlayi Haw. (grl) crosses. Eleven plants produced 1–3% large size pollen and one plant produced more than 3% of this type of pollen. Twelve triploid and seven tetraploid hybrids were obtained when these plants were used in crosses with acl. On the other hand, 75 triploid hybrids were obtained from the second type of cross. The average pollen stainability in the diplogynoid triploid cmm × grl hybrids was 18.9%, with a range of 2–34.4%. Forty-four to 54.6% of meiocytes with parallel spindles in metaphase II and anaphase II were observed in microsporogenesis of these hybrids. For each clone, the frequency of triplandroids predicted according to the frequency of meiocytes with parallel, fused and tripolar spindles in anaphase II were 52.3, 36.6, and 45.2%, respectively. These values were highly superior to the frequency of triplandroids predicted according to the number of dyads and triads observed, 8.8, 0.7, and 3.9%, respectively. However, triplandroid frequencies predicted according to the frequencies of fused and tripolar spindles agree with the triplandroid frequencies observed. The frequencies of stainable pollen grains are not completely accounted for by the formation of fused and tripolar spindles. In view of the variability encountered in size, it is assumed that a high proportion of gametophytes with aneuploid chromosome numbers are also stainable. A hypothesis is put forward regarding the possible genetic control of triplandroid formation in the diplogynous triploid hybrids analyzed.Key words: 2n gametes, triploid hybrids, spindle orientation, Solanum commersonii Dun.

This article presents the results of application of cisgenic biolistic transformation for the accelerated production of new forms of potato with increased resistance to late blight. The reason for late blight development is the parasitic organism Phytophthora infestans, belonging to oomycetes (pseudo-fungi), which infects valuable agricultural plants. In this study, with the aim of combating P. infestans, a number of experiments on the biolistic transformation of the most common potato varieties Aksor and Nevskiy were carried out in Kazakhstan. Two potato genes – Rpi-vnt1.1 and StREM1.3 – were selected as targets for introduction. Expression of the first gene should be activated, and the expression of the REMORIN1.3 gene should be suppressed. Rpi-vnt1.1 was under the control of Solanum tuberosum polyubiquitin gene promotor (Pat) and Arabidopsis thaliana polyubiquitin 5 gene terminator (ubq5). Knock-down double stranded RNA-hairpin gene construction for StREM1.3 silencing was under the control of Solanum tuberosum phytochrome B gene promotor (phyB) and Arabidopsis thaliana hot-shock protein 18.2 terminator (HSP18.2). Three series of biolistic transformation were carried out, as a result of which 636 regenerated plants of potato varieties Aksor and Nevskiy were obtained. DNA was extracted from the plant material of potato transformant plants in the quality and quantity suitable for PCR analysis for the presence of an insert. PCR analysis was carried out, revealing 52 plants carrying the VNT insert. StREM1.3 silencing gene construction was detected in plant lines by qPCR, based on comparative analysis of of gene expression level and revealed 6 lines with reliably lower StREM1.3 expression level in comparison with wild-type plants.
