Can sieve-element plastids in Panicum maximum (Poaceae) leaves act in the blockage of injured sieve-tube elements?
(Elsevier Gmbh, Urban & Fischer Verlag, 2008-01-01)
The ultrastructural features and the plastid changes caused by sample preparation were studied in sieve elements of Panicum maximum leaves. Samples of expanded leaves, taken near the ligule region, were fixed and processed ...

Phloem sap of tomato plants contains a DIR1 putative ortholog
(Elsevier Gmbh, 2009-03-15)
Arabidopsis thaliana defective in induced resistance 1 (At-DIR1) has been characterized as a protein responsible for the generation or transmission of the still unknown signal involved in systemic acquired resistance. This ...
Phloem transport of assimilates in relation to flowering time and senescence in barley grown with different availabilities of nitrogen and phosphorus
(Taylor & Francis Ltd, 2017-08)
Understanding the way in which N and P availability affects the transport of sugar and amino acids is crucial to improve grain quality and yield. Thus, in the present study, two greenhouse and field experiments were conducted ...
Regulation of glutamine synthetase 1 and amino acids transport in the phloem of young wheat plants
(Elsevier France-editions Scientifiques Medicales Elsevier, 2009-05)
The possible regulation of amino acid remobilization via the phloem in wheat (Triticum aestivum L.) by the primary enzyme in nitrogen (N) assimilation and re-assimilation, glutamine synthetase (GS, E.C. 6.3.1.2) was studied ...
Phloem sugars and amino acids as potential regulators of hordein expression in field grown malting barley (Hordeum vulgare L.)
(Elsevier, 2014-09)
The commercial quality of malting barley is dependent on the content and composition of grain proteins which are subjected to nitrogen (N) and sulfur (S) control. In nutrient deficient soils, grain protein content is mainly ...
GUS expression in sweet oranges (Citrus sinensis L. Osbeck) driven by three different phloem-specific promoters
(SPRINGERNEW YORK, 2012-11)
Huanglongbing (HLB) is associated with Candidatus Liberibacter spp., endogenous, sieve tube-restricted bacteria that are transmitted by citrus psyllid insect vectors. Transgenic expression in the phloem of specific genes ...
