    Notes: Abstract Steady-state mRNA levels of nuclear (rbcS, cab, tubA) and plastid (rbcL, psbA) encoded genes were determined in tomato leaves of different developmental stages. Transcripts were analyzed at four-hour intervals throughout a diurnal cycle in 4 cm-long terminal leaflets, while mRNA levels of the chlorophyll a/b-binding protein (cab), and the small and large subunit of RuBPC/Oase (rbcS, rbcL) are high. At different time points during the day the mRNAs accumulate to characteristic levels. Minor fluctuations of such mRNA levels were determined in the case of rbcS, rbcL, psbA and tubA, while significant alterations are observed for the chlorophyll a/b-binding protein transcript levels. LHCP II transcripts accumulate during the day, reach highest levels at noon and decline to non-detectable levels at 5 a.m. The cab mRNA fluctuates with a periodic length of approximately 24 hours suggesting the existence of a circadian rhythm (“biological clock”), which is involved in gene activation and inactivation. The mRNA oscillation with the same periodic length, but altered amplitude, continues to be present in plants which are kept under extended dark or light conditions. Different mRNA fluctuation patterns are observed for rbcS, rbcL, and psbA under such experimental conditions.

    Notes: Abstract We have previously reported the isolation and characterization of tomato nuclear genes encoding two types of chlorophyll a/b-binding (CAB) polypeptides localized in photosystem (PS) I and two types of CAB polypeptides localized in PSII. Sequence comparisons shows that all these genes are related to each other and thus belong to a single gene family. Here we report the isolation and characterization of an additional member of the tomato CAB gene family, the single tomato nuclear gene, designated Cab-8, which encodes a third type of CAB polypeptide localized in PSI. The protein encoded by Cab-8 is 65% and 60% divergent from the PSI Type I and Type II CAB polypeptides, respectively. The latter two are 65% divergent from each other. Only some short regions of the polypeptides are strongly conserved. The Cab-8 locus maps to chromosome 10, 9 map units from Cab-7, the gene encoding the Type II PSI CAB polypeptide. The Cab-8 gene contains two introns; the first intron matches in position the single intron in the Type II PSII CAB genes and the second intron matches in position the second intron in the Type II PSI CAB gene. Like other CAB genes, Cab-8 is light-regulated and is highly expressed in the leaf and to a lesser extent in other green organs.

    Light-regulated protein and mRNA synthesis in root caps of maize (1988)
    Springer
    Plant molecular biology 11 (1988), S. 27-34

    ISSN: 1573-5028
    Keywords: maize ; root ; root cap ; root mRNA ; root photomorphogenesis ; Zea mays
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract Illumination of maize roots initiates changes in mRNA levels and in the activities of proteins within the root cap. Using Northern analysis we showed a 5–6-fold increase in the levels of three specific mRNAs and a 14-fold increase in plastid mRNA. This increase is rapid, occurring within 30 minutes of illumination. With prolonged periods of darkness following illumination, messages return to levels observed in dark, control caps. For two species of mRNA illumination results in a reduction in message levels. Light-stimulated increases in the levels of specific mRNAs are proportionally greater than are increases in the activities of corresponding proteins. We suggest that the light-stimulated increase in protein activity in root caps may be preceded by and occur as a consequence of enhanced levels of mRNA. Our work suggests that photomorphogenesis in roots could involve changes in the levels of a wide variety of mRNAs within the root cap.

    Changes of the diurnal and circadian (endogenous) mRNA oscillations of the chlorophyll a/b binding protein in tomato leaves during altered day/night (light/dark) regimes (1989)

    Topics: Biology
    Notes: Abstract Characteristic steady-state mRNA level oscillations were monitored for the chlorophyll a/b-binding (cab) protein in tomato plants grown under the natural day/night (light/dark) regime as well as under constant environmental conditions. This typical expression pattern was altered when plants were transferred to different light/dark regimes. For example, by shifting the light phase by six hours, a change of the time points of maximum and minimum of expression level was monitored, while the principal oscillation pattern remained the same. It appeared that the transition from dark to light is involved in determining the time points of minima and maxima of mRNA accumulation. After exposing tomato plants to an abnormal light/dark periodicity (e.g. six hours of alternating light/dark) an altered oscillation pattern was determined: within 24 hours two maxima of cab mRNA levels were detected. However, this ‘entrained’ abnormal rhythm was not manifested at the molecular level and the circadian pattern reappeared under constant environmental conditions (e.g. darkness). This result favours the hypothesis that the oscillation pattern of the cab mRNA in tomato plants is not only endogenous but also hereditary.

    Effect of dark phases and temperature on the chlorophyll a/b binding protein mRNA level oscillations in tomato seedlings (1990)

    Topics: Biology
    Notes: Abstract External parameters (e.g. light/dark alterations and temperature) were tested for their ability to influence the expression pattern of the chlorophyll a/b binding protein (cab) genes and the small subunit of RuBPC/Oase (rbcS) genes. Particular interest was focused on the alterations of diurnal/circadian oscillation patterns of cab mRNA levels. Chlorophyll a/b binding protein and small subunit of RuBPC/Oase mRNA oscillations were observed in tomato seedlings grown without environmental perturbations (constant illumination and temperature), indicating that these genes are controlled by an endogenous rhythm. The rhythmic fluctuation patterns revealed a period of about 32 hours and a weakly expressed amplitude. A several-fold increase of the cab mRNA amplitude and a reduction of the period to about 24 hours (circadian) was monitored after exposure of the tomato seedlings to 3, 6 or 9 hours of darkness. The elevated amplitude disappeared at consecutive days if seedlings were not exposed to further dark phases. A circadian rhythm with clearly expressed cab mRNA amplitudes was also present after the plants had been transferred to darkness at various circadian times. However, under those circumstances the time points of maximum and minimum transcript levels were shifted by respective hours. Alteration of the growth temperature from 24°C to 10°C or 30°C at constant illumination or in a light/dark cycle resulted in a reduction of the amplitudes or of the steady-state mRNA levels. Such extreme temperature changes do not induce or enhance the diurnal cab mRNA oscillations.

    Notes: Abstract The diurnal and circadian expression of light-harvesting genes (Lhc) is well documented for many plant species of the ‘Angiospermae’ division. Here we present the diurnal mRNA levels of species of the Gymnospermae, Pteridophyta, Bryophyta and Phycophyta divisions. Except for four Coniferophytina species, diurnal Lhc mRNA accumulation is detected in fern, moss and algae, supporting the idea that the concept of ‘circadian clock’-controlled gene expression is an ancient process. Possible reasons why plants need the ‘circadian clock’ control mechanism are discussed.

    Differential expression of nuclear- and organelle-encoded genes during tomato fruit development (1988)

    Notes: Abstract Steady-state mRNA levels of nuclear-and organelle-encoded genes were determined during fruit development and ripening. Transcripts specific for subunits of the mitochondrial and chloroplast ATPase complexes appear simultaneously and reach high levels two to three weeks after anthesis, but follow a different expression pattern during the ripening period. While the chloroplast-specific mRNA levels continuously decrease to low levels in ripe tomato fruits, the transcripts specific for two mitochondrial ATPase subunits continue to be present at relative high levels in red fruits. Transcript levels for the fructose-1,6-bisphosphate aldolase increase significantly during ripening. Structural proteins such as the alpha-subunit of tubulin and the hydroxyproline-rich glycoprotein extensin are expressed during maximal fruit growth. In addition, comparisons of mRNA levels of different genes in several plant organs (leaf, fruit, stem, and root) show characteristic differences. The results presented in this paper demonstrate that changes at the transcriptional or post-transcriptional level during fruit development can be correlated with morphological and physiological alterations.
