Detection of Bean Golden Mosaic Virus in Host Tissues and Infectivity of Its Genome in Bean Mesophyll Protoplasts
… in a limited number of mesophyll cells, in some sieve elements and phloem parenchyma of trifoliolate leaves, and in sieve elements and phloem parenchyma of the stem. No viral antigen was detected from the roots. Isolated cells from trifoliolate leaves showed BGMV-specific fluorescence in the …

The developmental transcriptional landscape and organizing function of the sieve element in the root meristem
… in form of sugars. The latter are transported in sieve elements, specialized tube-like cells in the phloem. While several regulators of sieve element differentiation have been described, many remain unknown. Furthermore, the temporal cascade of differentiation regulation remains unclear due to …

Mechanism of vector resistance in groundnut to control groundnut rosette virus disease in Sub-Saharan Africa
… to an inhibition of phloem feeding from the sieve elements. Consequently, virus transmission of all three agents of rosette disease was almost totally absent even under very high pressure of viruliferous aphids. Further investigation of the underlying mechanism of resistance in ICG 12991 …

Effects of sublethal and lethal temperatures on plant cells
… had been exposed to C¹⁴O₂. The function of the sieve elements in conduction of the C¹⁴ photosynthates may have been temporarily blocked by the heat treatment. Loss of chlorophyll and swelling of chloroplasts were observed in cells of elodea leaves exposed to sublethal temperature treatments. At …

Molecular detection and identification of phytoplasmas in sugarcane in Hawaii, Thailand, Cuba and Near East
… sugarcane white leaf phytoplasma only in phloem sieve tubes of diseased sugarcane leaves but not in adjacent cells to the sieve elements including companion cells and phloem parenchyma as well. According to ultrastructural observations under TEM, parenchymatic cells of bundle sheath and mesophyll …
