Cytology of the minor-vein phloem in 320 species from the subclass Asteridae suggests a high diversity of phloem-loading modes

open access: yesFrontiers in Plant Science, 2013
The discovery of abundant plasmodesmata at the bundle sheath/phloem interface in Oleaceae (Gamalei, 1974) and Cucurbitaceae (Turgeon et al., 1975) opened the questions whether these plasmodesmata are functional in phloem loading and how widespread is ...

Favipiravir Suppresses Zika Virus (ZIKV) through Activity as a Mutagen

open access: yesMicroorganisms, 2023
In a companion paper, we demonstrated that the nucleoside analogue favipiravir (FAV) suppressed Zika virus (ZIKV) replication in three human-derived cell lines—HeLa, SK-N-MC, and HUH-7.

Role of intermediary cells in Peltodon radicans (Lamiaceae) in the transfer of calcium and formation of calcium oxalate crystals

open access: yesBrazilian Archives of Biology and Technology, 2005
With the objective of studying the connection between calcium oxalate crystals formation and the phloem, fragments of leaves of Peltodon radicans Pohl (Lamiaceae) were fixed and processed, for light and electron-transmission microscopes.

Associations between the acclimation of phloem-cell wall ingrowths in minor veins and maximal photosynthesis rate

open access: yesFrontiers in Plant Science, 2014
The companion cells (CCs) and/or phloem parenchyma cells (PCs) in foliar minor veins of some species exhibit invaginations that are amplified when plants develop in high light (HL) compared to low light (LL).

Foliar phloem infrastructure in support of photosynthesis

open access: yesFrontiers in Plant Science, 2013
Acclimatory adjustments of foliar minor loading veins in response to growth at different temperatures and light intensities are evaluated. These adjustments are related to their role in providing infrastructure for the export of photosynthetic products ...

Challenges of stem cell therapies in companion animal practice

open access: yesJournal of Veterinary Science, 2020
Regenerative medicine using stem cells from various sources are emerging treatment modality in several refractory diseases in veterinary medicine. It is well-known that stem cells can differentiate into specific cell types, self-renew, and regenerate. In addition, the unique immunomodulatory effects of stem cells have made stem cell transplantation a ...

Identification of sieve elements and companion cell protoplasts by a combination of brightfield and fluorescence microscopy

open access: yesApplications in Plant Sciences, 2018
Premise of the Study Phloem‐limited diseases are becoming increasingly pervasive, threatening the existence of crops worldwide. Studies of phloem diseases are complicated by the inaccessibility of the phloem tissue.

Structural and functional heterogeneity in phloem loading and transport

open access: yesFrontiers in Plant Science, 2013
The phloem is often regarded as a relatively straightforward transport system composed of loading (collection), long-distance (transport) and unloading zones.

A companion cell-dominant and developmentally regulated H3K4 demethylase controls flowering time in Arabidopsis via the repression of FLC expression. [PDF]

open access: yesPLoS Genetics, 2012
Flowering time relies on the integration of intrinsic developmental cues and environmental signals. FLC and its downstream target FT are key players in the floral transition in Arabidopsis.

Characterization and Potential Applications of Dog Natural Killer Cells in Cancer Immunotherapy. [PDF]

open access: yes, 2019
Natural killer (NK) cells of the innate immune system are a key focus of research within the field of immuno-oncology based on their ability to recognize and eliminate malignant cells without prior sensitization or priming.
