Faucaria felina H. Jacobsen
No full textMesembryanthemum ringens Linnaeus var. felinum Linnaeus, Species Plantarum 1: 487. 1753. RCN: 3708. Lectotype (Groen & van der Maesen in Bothalia 29: 39. 1999): [icon] "Mesembryanthemum rictum felinum repraesentans" in Dillenius, Hort. Eltham. 2: 240, t. 187, f. 230. 1732. Current name: Faucaria felina (Weston) Schwantes ex H. Jacobsen (Aizoaceae). Note: According to Ingram (in Baileya 17: 47-48. 1970), M. felinum Weston (1770) was published without reference to Linnaeus, preventing the recombination of Linnaeus’ varietal epithet in Mesembryanthemum. He gives the correct name as Faucaria felina (Weston) Schwantes ex H. Jacobsen.Published as part of Jarvis, Charlie, 2007, Chapter 7: Linnaean Plant Names and their Types (part M), pp. 651-689 in Order out of Chaos.

Afroedura haackei Jacobsen, Kuhn, Jackman & Bauer, 2014, stat. nov.
No full text<i>A. haackei</i> stat. nov. Onderstall, 1984 <p>(Fig. 5 A)</p> <p> <b>Distribution.</b> Granite outcrops of the southern Lowveld of Mpumalanga province, South Africa (Bauer 2014h) (Figs. 4, 6). TM 49920 from Farm Scrutton 23MT (2230AD) (illustrated by Pienaar 1978 as <i>A. transvaalica</i>) appears similar or identical to <i>A. haackei</i> (Onderstall 1984, Jacobsen 1990) and may represent a translocation.</p> <p> <b>Remarks.</b> This species was described as a subspecies of <i>A. pondolia</i> (Onderstall 1984), but was amended by Jacobsen (1990) to <i>A. multiporis haackei</i>. Our molecular data confirm the relationship of the two taxa, but based on substantial genetic differentiation (Fig. 1) as well as differences in body size and precloacal pore counts (see Table 4), and their allopatric distribution, we here formally elevate <i>A. haackei</i> to specific rank. The species was previously listed in the <i>South African Red Data Book</i> as “Restricted” (Jacobsen 1988a) but is currently considered to be of Least Concern (Bauer 2014h).</p>Published as part of <i>Jacobsen, Niels H.

Cisgenesis: an important sub-invention for traditional plant breeding companies
No full textModern plant breeding is highly dependent on new technologies to master future problems. More traits have to be combined, frequently originating from wild species. Traditional breeding is connected with linkage drag problems. The crop plant itself and its crossable species represent the traditional breeders gene pool. GM-breeding is a new way of improving existing varieties. Transgenes originate from non-crossable species and are representing a new gene pool. For release of GM-plants into the environment and onto the market in Europe Directive 2001/18/EC has been developed, primarily based on GM-technology and not on gene source. In society, opposition against GM crops is complicating the implementation of GM crops. In this paper, it is shown that not only transgenes, representing a new gene pool but also cisgenes and intragenes are available, representing the breeders gene pool. Cisgenes are natural genes and intragenes are composed of functional parts of natural genes from the crop plant itself or from crossable species. Cisgenesis is the combined use of only cisgenes with marker-free transformation, mimicking linkage drag free introgression breeding in one step. Therefore, cisgenesis is a new sub-invention in the traditional breeding field and indicates the need for reconsideration of GM Directives. Inventions are frequently containing not only hardware elements, but also software and orgware elements. For cisgenesis it is foreseen that the technical (hardware) and bioinformatic (software) elements will develop smoothly, but that implementation in society is highly dependent on acceptance and regulations (orgware). It could be made in a step by step approach by specific crop-gene derogations from the Directive, followed by adding cisgenesis to annex 1b of Directive 2001/18/EC for exemption. At present GM crops can only be introduced by large companies. An open innovation approach for cisgenesis by public private partnership including traditional SMEs has been discussed. Cisgenesis has been exemplified for resistance breeding of potato to Phytophthtora infestans
