In solanaceous plants such as tomato and tobacco, the sucrose transporter SUT1 is crucial for phloem loading. Using GUS as a reporter, the promoter and other regulatory cis elements required for the tomato LeSUT1 expression were analyzed by heterologous expression of translational chimeric constructs in tobacco.

Intercommunication between mammalian oocytes and companion somatic cells
BioEssays, 1991AbstractCellular interactions in the mammalian ovarian follicle between its germ‐line and somatic cell components are crucial for its development and function. These interactions are mediated by both membrane gap junctions and paracrine factors. Somatic cell‐to‐oocyte communication is essential for oocyte growth and the regulation of meiotic maturation.

Companion Cells and Transfer Cells
1975Phloem tissue as a whole, according to the introduction of this term by Nageli (1858), consists of sieve elements, sclerenchymatic elements and parenchymatic elements. Companion cells and transfer cells, the two cell types to be considered more in detail in the following, belong to the latter group.

Plastids in sieve elements and their companion cells
Planta, 1973Plastids have been identified in the sieve elements and/or companion cells of 14 monocotyledon species. In contrast to earlier reports, plastids are present in the sieve elements of Smilax and the companion cells of Tradescantia. The development and fine structure of the sieve-element plastids in Smilax do not differ from the type found in all of the ...

Structure and development of P-protein in phloem parenchyma and companion cells of legumes
Tissue and Cell, 1975Phloem parenchyma and companion cells from four species of legumes, Phaseolus vulgaris L., Melilotus alba Desr., Desmodium canadense, L. and Dolichos lablab L., were examined electron microscopically to estabish the presence, structure and development of P-protein.

The rendez-vous of mobile sieve-element and abundant companion-cell proteins
Current Opinion in Plant Biology, 2018Thousands of sieve tube exudate proteins (STEP) have now been identified and predicted to fulfill a diversity of functions. However, most STEPs should be considered putative, since methods to collect sieve tube exudates have many technical drawbacks, and advanced functional characterization will be required to distinguish contaminant from bonafide ...

Immune Reconstitution With Activated T Cells In Companion Canines With Lymphoma
Blood, 2013Abstract Companion canine cancer provides a clinically-relevant immunotherapy model for human malignancies because of their large size, intra-species genetic diversity, genetic similarity of tumors to human oncology, and spontaneously occurring tumors that develop despite an intact immune system ...

Principles and Applications of Flow Cytometry and Cell Sorting in Companion Animal Medicine
Veterinary Clinics of North America: Small Animal Practice, 2012Flow cytometry measures multiple characteristic of single cells using light scatter properties and fluorescence properties of fluorescent probes with specificity to cellular constituents. The use of flow cytometry in the veterinary clinical laboratory has become more routine in veterinary diagnostic laboratories and institutions (http://www.vet.k-state.

A ‘Do It Yourself’ Pipeline to Generate a Cell Atlas Companion Website
American Journal of Respiratory and Critical Care MedicineAbstract Rationale: As sequencing methodologies continue to improve, and new methods such as spatial transcriptomics technologies rapidly emerge, we must develop and streamline methods to effectively and efficiently communicate these vast quantities of data. The process of using an atlas data mining website to showcase single cell and
