EcoMeristem, a model of morphogenesis and competition among sinks in rice. 1. Concept, validation and sensitivity analysis
Functional Plant Biology - Tập 33 Số 4 - Trang 309 - 2006
Delphine Luquet, Michaël Dingkuhn, Hae Koo Kim, L. Tambour, Anne Clément‐Vidal
Because of rapid advances in functional genomics there is an increasing demand for models simulating complex traits, such as the physiological and environmental controls of plant morphology. This paper describes, validates and explores the behaviour of the structural–functional model EcoMeristem, developed for cereals in the context of the Generation Challenge Program (GCP; CGIAR). EcoMeri...... hiện toàn bộ
Spatial Variation of the Electrical Properties of Chara australis. II. Membrane Capacitance and Conductance as a Function of Frequency
Functional Plant Biology - Tập 10 Số 3 - Trang 353 - 1983
Terry C. Chilcott, H.G.L. Coster, Koreaki Ogata, J. R. Smith
The water-film technique has been used to measure the frequency dependence of the membrane capacitance and conductance as a function of position along illuminated cells of C. australis. At low frequencies (< 1 Hz) the behaviour of the membrane capacitance was found to be strongly dependent upon both frequency and position. A complicated oscillatory pattern was observed which is possibl...... hiện toàn bộ
Effects of contrasting shade treatments on the carbon production and antioxidant activities of soybean plants
Functional Plant Biology - Tập 47 Số 4 - Trang 342 - 2020
Muhammad Ali Raza, Ling Feng, Nasır Iqbal, Imran Khan, Tehseen Ahmad Meraj, Zeng Jin Xi, Muhammd Naeem, Saeed Ahmed, Muhammad Tayyab Sattar, Yuan Kai Chen, Chen Hui Huan, Mukhtar Ahmed, Feng Yang, Wenyu Yang
In China, maize-soybean relay-intercropping system follow the two main planting-patterns: (i) traditional relay-intercropping; maize-soybean equal row planting, where soybean experience severe maize shading on both sides of plants, and (ii) modern relay-intercropping; narrow-wide row planting, in this new planting pattern only one side of soybean leaves suffer from maize shading. Therefore...... hiện toàn bộ
Photosynthetic Responses of Pisum sativum to an Increase in Irradiance During Growth. II. Thylakoid Membrane Components
Functional Plant Biology - Tập 14 Số 1 - Trang 9 - 1987
WS Chow, J. M. Anderson
Following the transfer of pea plants grown at low irradiance (60 �mol photons m-2 s-1, 16 h light/8 h dark cycles) to high irradiance (390 �mol photons m-2 s-1), the extents and time courses of the increase in the concentrations of thylakoid membrane components on a chlorophyll basis have been determined. The increase in cytochrome f (~ 70%) and plastoquinone (~ 50%) contents occurred with...... hiện toàn bộ
Pathway of Carbon Transport Within Developing Ovules of Phaseolus vulgaris L
Functional Plant Biology - Tập 7 Số 6 - Trang 671 - 1980
JW Patrick, Roy E. McDonald
14C-labelled photosynthates, on reaching developing ovules of Phaseolus vulgaris plants, were transported rapidly and evenly throughout the highly vascularized seed coats. Apoplastic transfer of 14C-labelled photosynthates from the seed coats to the developing embryos occurred over the entire inner surface of the seed coats. Further lateral transfer of the photosynthate through the cotyled...... hiện toàn bộ
Partial Tryptic Digestion of Cucurbitin from Pumpkin Seed
Functional Plant Biology - Tập 8 Số 6 - Trang 507 - 1981
R.J. Blagrove, Glenn G. Lilley, Alexander A. Kortt
A stable digestion intermediate was observed when cucurbitin, the crystalline storage globulin of pumpkin [Cucurbita moschata (Duch.) Poir.] seed, was treated with trypsin. The major digestion product, termed cucurbitin-T, was isolated as a homogeneous protein of M, 285 000+ 10000 by chromatography over Sepharose CL-6B. The treatment with trypsin lowered the isoelectric point, decreased th...... hiện toàn bộ
Hydrogen sulfide may function downstream of hydrogen peroxide in salt stress-induced stomatal closure in Vicia faba
Functional Plant Biology - Tập 46 Số 2 - Trang 136 - 2019
Yinli Ma, Wei Zhang, Jiao Niu, Yu Ren, Fan Zhang
The roles of hydrogen sulfide (H2S) and hydrogen peroxide (H2O2) in signalling transduction of stomatal closure induced by salt stress were examined by using pharmacological, spectrophotographic and laser scanning confocal microscopic (LSCM) approaches in Vicia faba L. Salt stress resulted in stomatal closure, and this effect was blocked by H2S modulators hypotaurine (HT), aminooxy acetic ...... hiện toàn bộ
Genetic control of lysine metabolism in maize endosperm mutants
Functional Plant Biology - Tập 31 Số 4 - Trang 339 - 2004
Ricardo Antunes Azevedo, Catherine Damerval, Peter J. Lea, Jacques Landry, Cláudia de M. Bellato, Lyndel W. Meinhardt, Martine Le Guilloux, Sonia Delhaye, Alejandro Toro, Salete Aparecida Gaziola, Vanderlei Aparecido Varisi, Priscila Lupino Gratão
The capacity of three maize endosperm opaque mutants (o10, o11 and o13) to accumulate soluble lysine in the seed in relation to their wildtype counterpart, W22+, was investigated. The W22o13 and W22o11 mutants exhibited 278% and 186% increases in soluble lysine, respectively, while for W22o10, a 36% decrease was observed, compared with the wildtype. A quantitative and qualitative study of ...... hiện toàn bộ
Influence of plant age and growth conditions on nitrate assimilation in roots of Lotus japonicus plants
Functional Plant Biology - Tập 29 Số 4 - Trang 485 - 2002
Purificación Pajuelo, Eloísa Pajuelo, Alicia Orea, J. Romero, Antonio J. Márquez
In roots of Lotus japonicus (Regel) Larsen cv. Gifu, the level of NADH-nitrate reductase (NR) activity and protein, as well as ferredoxin-nitrite reductase activity and nitrate accumulation, were higher in roots of young plants, and decreased in mature plants grown in seed trays. When plants were grown in larger pots, the decrease in NR activity and nitrate accumulation took place at a la...... hiện toàn bộ
Retrotransposon-based molecular markers for assessment of genomic diversity
Functional Plant Biology - Tập 41 Số 8 - Trang 781 - 2014
Ahmed M. Alzohairy, Gábor Gyulai, Mohamed Fawzy Ramadan, Sherif Edris, Jamal S. M. Sabir, Robert K. Jansen, Hala F. Eissa, Ahmed Bahieldin
Retrotransposons (RTs) are major components of most eukaryotic genomes. They are ubiquitous, dispersed throughout the genome, and their abundance correlates with genome size. Their copy-and-paste lifestyle in the genome consists of three molecular steps involving transcription of an RNA copy from the genomic RT, followed by reverse transcription to generate cDNA, and finally, reintegration...... hiện toàn bộ
