Genetic control of fatty acid composition in coconut (Cocos nucifera), African oil palm (Elaeis guineensis), and date palm (Phoenix dactylifera)
Planta - Tập 249 - Trang 333-350 - 2018
Predominant gene isoforms and expression bias in lipid metabolism pathways are highly conserved between oil-producing Arecaceae crop species coconut and oil palm, but diverge in non-oil-producing species date palm. Coconut (Cocos nucifera), African oil palm (Elaeis guineensis) and date palm (Phoenix dactylifera) are three major crop species in the Arecaceae family for which genome sequences have r......

New evidence for a role for thioredoxin h in germination and seedling development
Planta - Tập 200 - Trang 100-106 - 1996
Thioredoxin of the h-type — earlier linked to the reduction of wheat (Triticum durum Desf. cv. Monroe) endosperm proteins — was converted from an oxidized to a partially reduced state during germination and seedling development. While the abundance of thioredoxin progressively decreased during this period, the availability of reducing equivalents, defined as the product of the relative abundance o......
Compartmentation and fluxes of inorganic phosphate in photosynthetic cells
Planta - Tập 161 - Trang 525-530 - 1984
An analysis of the compartmentation and fluxes of inorganic phosphate in isolated cladophyll cells from Asparagus officinalis was made in parallel with an ultrastructural study. The elution pattern of labelled inorganic phosphate (which indicates that the asparagus cells are behaving as a system of three compartments in series) was used to quantify the fluxes between the vacuole, cytoplasm and fre......
Effects of temperature and sink activity on the transport of 14C-labelled indol-3yl-acetic acid in the intact pea plant (Pisum sativum L.)
Planta - Tập 147 - Trang 216-224 - 1979
The velocity and intensity of basipetal transport of 14C-labelled indol-3yl-acetic acid (IAA) applied to the apical bud of the intact pea plant were influenced by the temperature to which the stem was exposed and were not influenced by changes in the temperature of the root system when this was controlled independently between 5°C and 35°C. The velocity of transport increased steadily with tempera......
Ethylene-induced growth and proton excretion in the aquatic plant Nymphoides peltata
Planta - Tập 157 - Trang 71-73 - 1983
In the presence of auxin, ethylene can promote growth in petioles of N. peltata (S.G. Gmel.) O. Kuntze. Acid buffer will also stimulate growth in the tissue and, in abraded petiole segments, ethylene-stimulated growth is accompanied by a marked acidification of the medium. Auxin stimulates growth in this tissue and, for various auxin and ethylene treatments, the amount of growth is closely correla......
Proton and anion transport at the tonoplast in crassulacean-acid-metabolism plants: specificity of the malate-influx system in Kalanchoë daigremontiana
Planta - Tập 179 - Trang 265-274 - 1989
Tonoplast vesicles were prepared from leaf mesophyll homogenates of the crassulacean-acid-metabolism plant Kalanchoë daigremontiana Hamet et Perrier de la Bâthie to study the effects of anions on ATP- and inorganic-pyrophosphate (PPi)-dependent H+ transport. In the presence of gramicidin, substrate hydrolysis by the tonoplast ATPase was characteristically stimulated by chloride and inhibited by ni......
Light-stimulated respiration in the green algaDunaliella tertiolecta: Involvement of the ultraviolet/blue-light photoreceptor(s) and phytochrome?
Planta - Tập 174 - Trang 422-425 - 1988
Starch breakdown and respiratory O2 uptake in the green algaDunaliella tertiolecta (Butcher) are stimulated not only by blue, but also by red light. In the present study, attempts are described to identify the photoreceptor(s) involved. Fluence rate-response curves with different slopes in the ultraviolet (UV)/blue and in the red spectral region as well as differences in the kinetics and in the un......
