Open AccessAn agroecological structure model of compost—soil—plant interactions for sustainable organic farming
Compost is used worldwide as a soil conditioner for crops, but its functions have still been explored. Here, the omics profiles of carrots were investigated, as a root vegetable plant model, in a field amended...

Open AccessAKT signaling is associated with epigenetic reprogramming via the upregulation of TET and its cofactor, alpha-ketoglutarate during iPSC generation
Phosphoinositide-3 kinase (PI3K)/AKT signaling participates in cellular proliferation, survival and tumorigenesis. The activation of AKT signaling promotes the cellular reprogramming including generation of in...

Distribution of alginate and cellulose and regulatory role of calcium in the cell wall of the brown alga Ectocarpus siliculosus (Ectocarpales, Phaeophyceae)
This work investigated a correlation between the three-dimensional architecture and compound–components of the brown algal cell wall. Calcium greatly contributes to the cell wall integrity.

UDP-d-galactose synthesis by UDP-glucose 4-epimerase 4 is required for organization of the trans-Golgi network/early endosome in Arabidopsis thaliana root epidermal cells
Endomembrane organization is essential for cell physiology. We previously identified an Arabidopsis thaliana mutant in which a plasma membrane (PM) marker GFP-NIP5;1 and trans-Golgi network/early endosome (TGN/EE...

Ultrastructural analysis of flagellar development in plurilocular sporangia of Ectocarpus siliculosus (Phaeophyceae)
Flagellar development in the plurilocular zoidangia of sporophytes of the brown alga Ectocarpus siliculosus was analyzed in detail using transmission electron microscopy and electron tomography. A series of cell ...

Pollen of Ceratostema (Ericaceae, Vaccinieae): tetrads without septa
The pollen morphology of two species of the Neotropical genus Ceratostema (Ericaceae) was examined by light, scanning and transmission electron microscopy. The Ceratostema species examined have 3-colporate pollen...

An antagonistic rhizoplane bacterium Pseudomonas sp. strain EC-S101 physiologically stresses a spinach root rot pathogen Aphanomyces cochlioides
We observed that an antagonistic rhizoplane bacterium Pseudomonas sp. strain EC-S101 induces excessive lateral and apical branching in the hyphae of a root rot phytopathogen Aphanomyces cochlioides AC-5 resulting...

Host-specific plant signal and G-protein activator, mastoparan, trigger differentiation of zoospores of the phytopathogenic oomycete Aphanomyces cochlioides
We found that the gradient of a host-specific attractant, cochliophilin A (5-hydroxy-6,7-methylenedioxyflavone) isolated from the roots of spinach triggered encystment followed by germination of zoospores of Apha...

Microscopic Studies on Attachment and Differentiation of Zoospores of the Phytopathogenic Fungus Aphanomyces cochlioides
The mode of aggregation, attachment and differentiation of zoospores of the phytopathogenic fungus Aphanomyces cochlioides when interacting with the host and a host-specific attractant and a G-protein activator, ...

Morphological Studies on Zoospores of Aphanomyces cochlioides and Changes during Interaction with Host Materials
The behavioral and morphological diversity of intact zoospores of Aphanomyces cochlioides and their dynamic morphological changes when interacting with the host or a host-specific zoospore attractant were studied...
