Two types of partial fertility in a diploid population of the fern Thelypteris decursive-pinnata (Thelypteridaceae)
Journal of Plant Research - - 2012
Narumi Nakato, Ryo Ootsuki, Noriaki Murakami, Shigeo Masuyama
Structure and dynamics of natural populations of polyploid trilliums
Journal of Plant Research - Tập 101 - Trang 121-130 - 1988
Akinori Uchino, Hajime Kanazawa
To confirm predominant self-pollination in natural populations ofTrillium apetalon (2n=4x=20, SSUU), chromosome constitutions of endosperms (2n=30, SSSUUU) fertilized in nature were analyzed for the patterns of H-segments of cold-treated chromosomes. The endosperms were of two kinds: homo-constitutions in which three chromosomes in each of the ten sets of homologues were of the same patterns of H-...... hiện toàn bộ
Chloroplast DNA phylogeography of Betula maximowicziana, a long-lived pioneer tree species and noble hardwood in Japan
Journal of Plant Research - Tập 123 - Trang 343-353 - 2009
Yoshiaki Tsuda, Yuji Ide
Betula maximowicziana is an ecologically and economically important tree species in Japan. In order to examine the phylogeographical pattern of the species in detail, maternally inherited chloroplast (cp) DNA variations of 25 natural populations of Betula maximowicziana and a total of 12 populations of three related species were evaluated by PCR-RFLP analysis. Two main haplotypic groups of B. maxi...... hiện toàn bộ
Fibrinolytic activity of some fungi isolated from self-heated composted fertilizer
Journal of Plant Research - Tập 103 - Trang 313-324 - 1990
Tahany Mohamed Ali Abdel-Rahman, Abdel-Aziz Mahmoud Salama, Mohamed Ibrahim Ahmed Ali, Hagwa Abdel-Hamid Tharwat
Mesophilic fungi isolated from organic fertilizer compost samples accounted for 70.94% of the total fungal count, while thermophilic and thermotolerant fungi constituted 29.05% of that count. Eight mesophilic fungal species, namelyAspergillus niger, Monilia sitophila, Paecilomyces divaricata, Penicillium chrysogenum, P. fellutanum, Scopulariopsis brevicaulis, S. brumptii andZygorhynchus japonicus;...... hiện toàn bộ
Developing a Photoautotrophic Micropropagation System for Woody Plants
Journal of Plant Research - Tập 114 - Trang 525-537 - 2001
Toyoki Kozai, Chieri Kubota
including cotyledonary stage somatic embryos have the ability to grow photoautotrophically (without sugar in the culture medium), and that the low or negative net photosynthetic rate of plants in vitro is due not to poor photosynthetic ability, but to the low CO2 concentration in the air-tight culture vessel during the photoperiod. Furthermore, we have shown that the photoautotrophic growth of se...... hiện toàn bộ
Virtual issue: Ecology and evolution of pteridophytes in the era of molecular genetics

Tissue culture inHaworthia
Journal of Plant Research - Tập 91 - Trang 83-91 - 1978
Yasunari Ogihara, Koichiro Tsunewaki
Effects of three auxins and kinetin on growth of the calluses of two species ofHaworthia, H. aristala andH. setata, were investigated. Stock calluses derived from the flower buds of these species were maintained for two years on RM-1964 agar medium containing 5 mg/l NAA. Small pieces of the stock calluses were transferred to the basal medium containing either auxin, IAA, NAA or 2,4-D in six differ...... hiện toàn bộ
Two Genotypes of Pedicularis chamissonis (Scrophulariaceae) Distributed at Mt. Gassan, Japan: Additional Genetic and Morphological Studies
Journal of Plant Research - Tập 114 - Trang 133-140
Noriyuki Fujii, Kunihiko Ueda, Yasuyuki Watano, Tatemi Shimizu
Steven, which is broadly distributed from northern Honshu of Japan to southwest Alaska, is known to comprise a few different cpDNA haplotypes grouped into two major (“Northern” and “Southern”) clades. This paper presents on the basis of chloroplast and nuclear DNA analyses that no gene flow exists between the two clades at Mt Gassan where two haplotypes D and J of the Northern and Southern clades...... hiện toàn bộ
Fast loading ester fluorescent Ca2+ and pH indicators into pollen of Pyrus pyrifolia
Journal of Plant Research - Tập 125 - Trang 185-195 - 2011
Haiyong Qu, Xueting Jiang, Zebin Shi, Lianmei Liu, Shaoling Zhang
Loading of Ca2+-sensitive fluorescent probes into plant cells is an essential step to measure activities of free Ca2+ ions in cytoplasm with a fluorescent imaging technique. Fluo-3 is one of the most suitable Ca2+ indicators for CLSM. We loaded pollen with fluo-3/AM at three different temperatures. Fluo-3/AM was successfully loaded into pollen at both low (4°C) and high (37°C) temperatures. Howeve...... hiện toàn bộ
Transcription factors in plants: Physiological functions and regulation of expression
Journal of Plant Research - Tập 111 - Trang 363-371 - 1998
Shuichi Yanagisawa
The control of gene expression in plants, as in all other living organisms, is essential for regulation of biological processes, such as body planning, development, differentiation and responses to various environmental signals. Transcription is the initial step at which genes are selected for expression and for modulation of levels of expression. In efforts to elucidate the mechanisms that contro...... hiện toàn bộ
