Flagellin and mannitol modulate callose biosynthesis and deposition in soybean seedlings.
Physiologia Plantarum : An International Journal for Plant Biology, 2023Callose is a polymer deposited on the cell wall and is necessary for plant growth and development. Callose is synthesized by genes from the glucan synthase-like family (GSL) and dynamically responds to various types of stress.

In pear (Pyrus bretschneideri), pollen tube growth is critical for the double fertilization associated with seed setting, which in turn affects fruit yield. The normal deposition of callose mediates the polar growth of pollen tubes.

(Z)-3-hexenol primes callose deposition against whitefly-mediated begomovirus infection in tomato.
The Plant Journal, 2022Rapid callose accumulation has been shown to mediate defense in certain plant-virus interactions. Our recent study demonstrated that exposure to the green leaf volatile (Z)-3-hexenol (Z-3-HOL) can prime tomato (Solanum lycopersicum) for an enhanced ...

A 43-year-old woman suffered a spontaneous corpus callosum disconnection, resulting in apraxia and apraxic agraphia confined to the left hand. She initially had a functionally total callosal disconnection. With time, the splenium of the corpus callosum became functional, and a computerized tomographic scan performed five months after the onset showed ...

A 39-year-old right-handed woman suffered a ruptured pericallosal aneurysm. Serial MRI studies showed damage to the genu and most of the body of the corpus callosum but not the splenium. Both supplementary motor areas (SMA) appeared intact. We studied the patient's praxis performance at intervals over a 4-month period with a standardized battery.

Delayed callose degradation restores the fertility of multiple P/TGMS lines in Arabidopsis.
Journal of Integrative Plant Biology, 2021Photoperiod/temperature-sensitive genic male sterility (P/TGMS) is widely applied for improving crop production. Previous investigations using the reversible male sterile (rvms) mutant showed that slow development is a general mechanism for restoring ...

Previous theories concerning the function of the corpus callosum have included a "topographic" column-to-column excitatory theory and a diffuse "regional" inhibitory theory. Here it is shown that a topographic inhibitory model, in conjunction with a postulate concerning surround inhibition among cortical columns, produces complementary patterns of ...

The corpus callosum is the main white matter tract between the two cerebral hemispheres and it connects both homolog and heterotopic regions in both hemispheres. The approximately 200 million axons are neatly organized from front to back with respect to which areas are connected.

Abstract Over the past century numerous cytochemical studies have shown that after various types of stress the polysaccharide callose is deposited, at selected sites, on to the plant cell wall. Callose mainly consists of linear 13-1, 3-glucanase (1-4), and one of its functions is to close the connections that unite protoplasts of ...
