AU - Sattolo, Mark H. AU - Hanley-Bowdoin, Linda K. AU - Kennedy, Theresa D. AU - Lane, Byron G. T2 - Canadian Journal of Biochemistry AB - The most prominent methionine-labeled protein made when cell-free systems are programmed with bulk mRNA from dry wheat embryos has been identified with what may be the most abundant protein in dry wheat embryos. The protein has been brought to purity and has a distinctive amino acid composition, Gly and Glx accounting for almost 40% of the total amino acids. Designated E because of its conspicuous association with early inhibition of dry wheat embryos, the protein and its mRNA are abundant during the "early" phase (0--1 h) of postimbibition development, and easily detected during "lag" phase (1--5 h), but they are almost totally degraded soon after entry into the "growth" phase of development, by about 10 h postimbibition. The most prominent methionine-labeled protein peculiar to the cell-free translational capacity of bulk mRNA from "growth" phase embryos is not detected as a product of in vivo synthesis. Its electrophoretic properties and its time course of emergence, after 5 h postimbibition development, suggest that this major product of cell-free synthesis may be an in vitro counterpart to a prominent methionine-labeled protein made only in vivo, by "growth" phase embryos. Designated G because of its conspicuous association with "growth" phase development, the cell-free product does not comigrate with any prominent dye-stained band in electrophoretic distributions of wheat proteins. The suspected cellular counterpart to G, also, does not comigrate with a prominent dye-stained wheat protein during electrophoresis, and although found in particulate as well as soluble fractions of wheat embryo homogenates it is not concentrated in either nuclei or mitochondria, as isolated.

AU - Bell, W. J. T2 - Science AB - Females of the tropical cockroach Xestoblatta hamata feed on urates offered by the male after copulation. Females on nitrogen-deficient diets ingest and transfer to their maturing oocytes more male-derived uric acid than do females on high-protein diets. In isolated females, the greatest uptake of uric acid by the ovaries occurs during the mating stage in the reproductive cycle. Uric acid from males contributes significantly to the female's nitrogen pool and may help shorten the time between mating and oviposition. In both field and laboratory experiments males choose high-protein foods and dietary uric acid.

T2 - Journal of Insect Physiology AB - (1) Megaloblatta blaberoides nymphs stridulate in response to disturbance. Sounds are produced by rubbing a pair of bilateral ventral files on the sixth sternum across opposing stationary scrapers located laterodorsally on the fifth sternum. The forward-moving file on one side and the backward-moving contralateral file generate sound simultaneously. (2) Intact nymphs produce a broad frequency band noise (5–35 kHz). Due to superposition of signals and silent pauses produced by the bilateral organs, no regular pattern of amplitude modulation is measurable. The sound produced by unilaterally muted nymphs contains regular pulse-train groups (forward and back cycle) each of which is divided into a short forward motion and a longer backward motion. These are interrupted by a short pause. A longer pause occurs prior to the anteriorly directed motion of the intact file. (3) Megaloblatta's proteinaceous tergal secretion is chemically and physically similar to that of Blatta orientalis. Coupling of acoustic warning, bright colour patterns, and chemical defence constitutes a multi-modal aposematic display which may be effective both nocturnally and diurnally against potential predators.

AU - Edwards, Helen AU - Jorgensen, Richard A. AU - Thompson, William F. T2 - Nucleic Acids Research AB - We have found major evolutionary changes in the types of transcripts produced by specific chloroplast genes, in particular those encoding the large subunit (LS) of ribulose-1,5-bisphosphate carboxylase and a photosystem II polypeptide (PII). Two distinct patterns of LS gene transcripts are revealed by hybridizing an LS gene probe to electrophoretically separated RNA from 19 angiosperms. Most species, including pea, contain the single transcript of approximately 1.6 kb previously observed in corn, spinach and mustard. However, in mung bean and other members of the legume genera Vigna and Phaseolus, the 1.6 kb transcript represents only a minor fraction of LS transcripts, and instead, two larger LS transcripts of approximately 2.4 and 2.6 kb predominate. The PII gene produces a single transcript in pea and most other species examined, while members of the related legume genera Vigna, Phaseolus and Glycine contain two additional transcripts which are smaller in size and probably represent specific RNA breakdown products. A single species, sweet pea (Lathyrus odoratus), contains a second PII transcript which is 0.2 kb larger than the approximately 1.2 kb transcript found in all species. The LS and PII genes map to the same 5 kb region in both pea and mung bean and are transcribed off the same DNA strand. In contrast, published studies indicate that the two genes are approximately 50 kb apart and are transcribed off opposite DNA strands in five other chloroplast genomes. These differences are probably the consequence of an approximately 50 kb inversion which distinguishes the pea and mung bean genomes from those of most other angiosperms (1).

AU - Thompson, William F. T2 - Cell AB - We examined the arrangement of sequences common to seven angiosperm chloroplast genomes. The chloroplast DNAs of spinach, petunia and cucumber are essentially colinear. They share with the corn chloroplast genome a large inversion of ∼50 kb relative to the genomes of three legumes—mung bean, pea and broad bean. There is one additional rearrangement, a second, smaller inversion within the 50 kb inversion, which is specific to the corn genome. These two changes are the only detectable rearrangements that have occurred during the evolution of the species examined (corn, spinach, petunia, cucumber and mung bean) whose chloroplast genomes contain a large inverted repeat sequence of 22–25 kb. In contrast, we find extensive sequence rearrangements in comparing the pea and broad bean genomes, both of which have deleted one entire segment of the inverted repeat, and also in comparing each of these to the mung bean genome. Thus there is a relatively stable arrangement of sequences in those genomes with the inverted repeat and a much more dynamic arrangement in those that have lost it. We discuss several explanations for this correlation, including the possibility that the inverted repeat may play a direct role in maintaining a conserved arrangement of chloroplast DNA sequences.

In the presence of fluorescent brightening agents, such as Calcofluor White M2R or Tinopal LPW, nonmicrofibrillar sheets of cellulose were synthesized by the bacteria. These sheets could then be converted to fibrils by washing with distilled water. Possible mechanisms for these modifications of cellulose assembly are disscussed.

In the presence of all of these substituted celluloses, normal fasciation of microfibril bundles to form the typical twisting ribbon is prevented. Alteration of ribbon assembly is most extensive in the presence of CMC, which often induces synthesis of separate, intertwining bundles of microfibrils. Freeze-etch preparations of the bacterial outer membrane suggest that particles that are thought to be associated with cellulose synthesis or extrusion may be specifically organized to mediate synthesis of microfibril bundles. These data support the previous hypothesis that the cellulose ribbon of A. xylinum is formed by a hierarchical, cell-directed, self-assembly process. The relationship of these results to the regulation of cellulose microfibril size and wall extensibility in plant cell walls is discussed.
