“…In an earlier work, Ellis (1981) suggested that the roughly 200 chloroplast proteins then directly resolvable by two-dimensional electrophoresis could be just the "tip of the iceberg." More recently it was shown that thylakoid membranes alone contain at least 75 major proteins (Herrmann et al, 1991;Pillen et al, 1996). We can roughly estimate the number of plastid proteins, considering the number of identified genes in the Synechocystis genome that belong to pathways and the functions known to reside partially, predominantly, or exclusively in plastids.…”

“…In contrast to higher plant ELIPs which are all nuclear encoded and synthesised on the cytoplasmic ribosomes with a N-terminal extension, some of the ELIP relatives in algae are encoded by plastid chromosomes like in the two red algae Porphyra purpurea and Cyanidium caldarium, or by cyanoplast genome like in the Glaucocystophyceae Cyanophora paradoxa (Miroshnichenko-Dolganov et al 1994, Green andKuhlbrandt 1995). This indicates that during evolution the ELIP genes must have been translocated from plastids into the nucleus and subsequently diverged into families of multiple peptides (Herrmann 1996, Pillen et al 1996.…”

Exposure of plants to light intensities higher than those required to saturate photosynthesis leads to a reduction in photosynthetic capacity. This effect is known as photoinhibition. Photoinhibition is followed by destruction of carotenoids, bleaching of chlorophylls and increased lipid peroxidation due to damage by oxygen‐derivatives. The oxygen concentration in chloroplasts in the light is high because of oxygen production by photosystem II (PSII). This can result in the release of reactive intermediates of reduced dioxygen such as superoxide radicals, hydroxyl radicals, hydrogen peroxide or singlet oxygen. In order to maintain their normal function under light stress conditions, chloroplasts have developed multiple repair and protection systems. The induction of specific light stress proteins, the ELIPs (for early light‐induced proteins) can be considered to be part of these protective responses. The accumulation of ELIPs under light stress conditions is correlated with the photoinactivation of PSII, degradation of the Dl‐protein of PSII reaction centre and changes in the level of pigments. Futhermore, the accumulation of ELIPs in the thylakoids is strictly controlled by the pigment content, especially by chlorophylls. Isolation of ELIPs in a native form and analysis of pigments bound to these proteins revealed that ELIPs can bind chlorophyll a and lutein. These data indicate that ELIPs might represent unique chlorophyll‐binding proteins which have a transient function(s) during light stress. A transient ‘pigment‐carrier’ function is postulated for ELIPs.

“…Many marker systems have been used, most are anonymous, including restriction fragment length polymorphisms (RFLPs), randomly amplified DNA polymorphisms (RAPDs), AFLPs, and SSRs, as well as a few morphological (e.g., color, seed type) and isozyme markers. Some single nucleotide polymorphisms (SNPs) within protein‐encoding genes are available for mapping in sugarbeet (Möhring et al, 2004; Schneider et al, 2001), and Pillen et al (1996) determined linkage relationships among 12 nuclear genes encoding chloroplast thylakoid proteins. In these published maps, the number of markers used ranged from 85 to 413 markers, and the total genetic distance summed across nine linkage groups ranged from 621 cM to 1057 cM.…”

In sugarbeet (Beta vulgaris subsp. vulgaris), many linkage maps have been constructed, but the availability of markers continues to limit utility of genetic maps in public domain programs. Here a framework genetic map is presented that is expandable and transferable to research programs interested in locating their markers on a consensus map. In its current framework, the primary markers used were amplified fragment length polymorphisms (AFLPs) that were anchored to Butterfass chromosome‐nomenclature linkage groups using linkage group specific markers validated in other populations. Thus, a common framework has been established that anchors 331 markers, including 23 newly mapped simple sequence repeat (SSR) markers, having a combined total of 526.3 cM among the nine beet linkage groups. The source of the mapping population was a sugarbeet × table beet population, and this is the first report of a map constructed with a relatively wide cross in B. vulgaris Segregation distortion was common (22% of loci), particularly extreme for Butterfass Chromosome 5, and predominantly favored the sugarbeet (seed parent) allele. Physical segments of the beet genome that carry mapped markers have been identified, demonstrating that physical and genetic mapping are facile and complementary applications for beet improvement.
