Aim & Scope

Journal of Plant Biology, an official publication of the Botanical Society of Korea, is an international journal devoted to basic researches in biochemistry, cellular biology, development, ecology, genetics, molecular biology, physiology, and systematics of plants. The Journal publishes the following categories of paper: Original articles -- For publication in Journal of Plant Biology the manuscript must provide a significant new contribution to our understanding of plants. All areas of plant biology are welcome. No limit on the length, but a concise presentation is encouraged. Reviews -- Invited by the EiC. Brief Communications -- Concise but independent report representing significant contribution to plant science. The Botanical Society of Korea was founded on November 30, 1957 to promote studies, disseminate and exchange information on the field of plant biology. The first issue of The Korean Journal of Botany, the official publication of the society, was published on April 1, 1958. It was published twice a year, but quarterly from 5th volume in 1962. In 1994, it was renamed to Journal of Plant Biology and published in English since 1996. The journal entered its 50th year of publication in 2007.

    Six young trees of Alnus tinctoria grown in isolation, each having different growing stage, were selected and the surface area of their roots, stems and leaves was determined. Each of the roots of more than 0.2mm in diameter and stems was cut at intervals of 10cm and their surface area was calculated with 2$\pi$rl from the average diameter (2r) of both sections (upper and lower) by making cylindrical estimation of the cut pieces. The leaf area measured was only one side area, and the volume of cut piece and amount of dry matter of each organ were also measured. The percentage to the surface area of the whole plant body by each organ was 4-12% in root, 7-9% in stem and 69-89% in leaf, respectively. There was relatively a little individual difference. However, the surface area ratios of root and stem showed a slightly increasing tendency while that of leaf decreasing according to the growing stage. The ratio of sum leaf area index (LAIi) was 2.3-4.0$m^2$/$m^2$-and that of the surface area index(SaIi) was 0.16-0.33$m^2$/$m^2$, respectively. It has been known that the stem surface area(SAI) to the leaf area index(LAI) is within the range of 31-53%, but the SAIi is within the range of 8-11% of the LAIi.

    The utilization of acetate by Dunaliella tertiolecta was examined, and the detections and assays of the enzymes of the tricarboxylic acid cycle and the glyoxylate pathway were described. Acetate could not be utilized as a sole carbon source for the growth. The carboxyl carbon of acetate was incorporated more rapidly into CO2 than the methyl carbon. It was identified that malate, succinate, citrate and etc., were accumulated whne [U-14C] acetate was supplied to the cell free homogenate. The following enzyme activities were measured; acetothiokinase, isocitrate dehydrogenase, fumarase, malate dehydrogenase and aconitase. Though isocitratase, malate synthetase, succinate dehydrogenase and oxoglutarate dehydrogenase could not be detected, 14C from succinate was easily contributed to CO2 and cell component. The evidence suggested that the glyoxylate pathway was not operative and showed that the TCA cycle was the all important pathway in the oxidation of acetate to CO2 in Dunaliella.

    The inhibitory effect of Inula sesquiterpene lactones on the growth of Phaseolus vulgaris was tested and the abnormality of the stem organization caused by the lactones was also examined. The longitudinal growth of the young stem and the expansion of the young leaf were stopped by the application of the lactones. However, this inhibitory effect was appeared and strictly restricted within the treated area. So the young shoot was observed for possible bending as a result of the unilateral application of the lactones. When the application of the lactones into the medium, the growth of the plant was entirely repressed. However, the growth of shoot and re-initiation of root were started after the plant was transfered to the lactone free medium. And partial reversal of inhibition of the stem growth was achieved by the additions of gibberelline and the lactones.

    The experiments were conducted to examine the injuries of $SO_2$, $NH_3$, and $SO_2$ and NH3 mixed gas to the germination and the growth of plants. Six kinds of plants were used as the material. These plants seeds were treated with the gases for five days. Rate of the germination and the growth in height of varying plants were different according to the components of the gases. The critical concentration of the gases for both the germination and the growth were in 5ppm of $SO_2$, 50ppm of $NH_3$, and 50ppm $SO_2$ and 50ppm $NH_3$ mixed gases. When a low concentration of $SO_2$ was treated together with NH3, especially it was reduced to 60 percent of the damage in the germination and the growth. In the treatemnt with $SO_2$, the germination of the seeds which soaked in water for 24 hours reduced the injuries more 40 percent than those which for one hour. It was observed that the seeds with thick coasts or with originally intact coats were suffered but little damaged by the gases, and the external symptoms of an injury were shown, at first, in water pore, and then, in guard cell on the leaves.

    The effect of phosphorus nutrition on the content of deoxyribonucleic acid(DNA), ribonucleic acid(RNA), crude protein and plant growth of soybean plant(Glycine max, Merr.) was studied. Yields of the above-and under-ground parts of the soybean plant in terms of dry weight, the amounts of crude protein, RNA and DNA continued to increase with increasing phosphorus supply. The amounts of RNA and crude protein were highest in the leaf tissues where most intensive growth was taking place. The relationships among DNA, RNA, crude protein and plant growth appeared to consist of the central dogma which has immortalized, while DNA in plant tissue was subject to charges cuased by external environmental facters such as phosphorus nutrition.

    To study the response to plant growth by the environmental factors, the effects of application of nitrogen on changes in the yield, crude protein, amino acids, chlorophyll, carotene, total phosphorus, acid-soluble phosphorus, phospholipids, RNA, and DNA were investigated with westerworlds 9Lolium sublatum) and perennial rye-grasses (Lolium perenne). The amounts of dry weight, crude protein, amino acids, chlorophyll, carotene, total phosphorus, acid-soluble phosphorus, phospholipids, RNA and DNA of both rye-grasses increased with adequately increasing nitrogen, and reached a maximum with an adequate application of nitrogen. The relationships between yields and crude protein contents, crude protein and RNA contents, and yields and RNA contents of westerworlds and perennial rye-grasses were found to be positively correlated, respectively. Therefore, in general, the response to plant growth by the environmental factors such as nitrogen nutrient may be summarized as follows: Environmental factors\longrightarrowDNA\longrightarrowRNA\longrightarrowProtein\longrightarrowPlant growth

    The spontaneous and induced reciprocal translocations of chromosomes in higher plants were reviewed and discussion was made on the utilization of this chromosome aberration in the production of seedless hybrid seeds in vegetable crops.
