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
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).
EcoMeristem con...
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
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 possibly
linked to ...
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
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, in thi...
Insights into root structure and function of Bassia indica: water redistribution and element dispersion
Functional Plant Biology - Tập 43 Số 7 - Trang 620 - 2016
In the last few decades, research has increasingly been aimed at clarifying how
root system architecture, physiology and function are related to environmental
drivers. ‘Negative halotropism’ has been defined as the alteration of root
growth direction to avoid salinity. We suggested that ‘positive halotropism’ may
be found in halophytes relying on salinity for optimal growth. Investigating
root str...
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
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 no noti...
Pathway of Carbon Transport Within Developing Ovules of Phaseolus vulgaris L
Functional Plant Biology - Tập 7 Số 6 - Trang 671 - 1980
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 cotyledons
exhi...
Partial Tryptic Digestion of Cucurbitin from Pumpkin Seed
Functional Plant Biology - Tập 8 Số 6 - Trang 507 - 1981
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 the
charge...
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
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 acid
(AO...
Genetic control of lysine metabolism in maize endosperm mutants
Functional Plant Biology - Tập 31 Số 4 - Trang 339 - 2004
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
the N co...
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
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 later
stage...
