Trienoic fatty acids and plant tolerance of high temperature.
The chloroplast membrane of higher plants contains an unusually high concentration of trienoic fatty acids. Plants grown in colder temperatures have a higher content of trienoic fatty acids.Expand

A qualitative analysis of the regulation of cyclic electron flow around photosystem I from the post-illumination chlorophyll fluorescence transient in Arabidopsis: a new platform for the in vivo
A transient in chlorophyll fluorescence after cessation of actinic light illumination, which has been ascribed to electron donation from stromal reductants to plastoquinone (PQ) by theExpand

Chloroplast biogenesis during the early stage of leaf development in rice
In rice, the developmental process in leaf formation can be divided into 7 stages (stages P0 to P6). We investigated chloroplast biogenesis and physiological changes in the developing leaves at theExpand

Leaf factors affecting the relationship between chlorophyll fluorescence and the rate of photosynthetic electron transport as determined from CO2 uptake.
CO2 uptake and chlorophyll fluorescence were measured under non-photorespiratory conditions in leaves from 14 plant species. The rate of CO2-dependent electron transport (JCO2) was calculated as fourExpand

Gymnosperms have increased capacity for electron leakage to oxygen (Mehler and PTOX reactions) in photosynthesis compared with angiosperms.
Oxygen plays an important role in photosynthesis by participating in a number of O2-consuming reactions. O2 inhibits CO2 fixation by stimulating photorespiration, thus reducing plant production. O2Expand

Elevated water temperature reduces the acute toxicity of the widely used herbicide diuron to a green alga, Pseudokirchneriella subcapitata
In the actual environment, temperatures fluctuate drastically through season or global warming and are thought to affects risk of pollutants for aquatic biota; however, there is no report about theExpand

Accumulation of menaquinones with incompletely reduced side chains and loss of alpha-tocopherol in rice mutants with alternations in the chlorophyll moiety.
The rice mutants M249 and M134 accumulate chlorophyllides a and b which are esterified with incompletely reduced alcohols such as geranylgeraniol, dihydrogeranylgeraniol, andExpand

Reduction of the primary donor P700 of photosystem I during steady-state photosynthesis under low light in Arabidopsis
During steady-state photosynthesis in low-light, 830-nm absorption (A830) by leaves was close to that in darkness in Arabidopsis, indicating that the primary donor P700 in the reaction center ofExpand

The pgr1 Mutation in the Rieske Subunit of the Cytochrome b6f Complex Does Not Affect PGR5-dependent Cyclic Electron Transport around Photosystem I*
Although photosystem I (PSI) cyclic electron transport is essential for plants, our knowledge of the route taken by electrons is very limited. To assess whether ferredoxin (Fd) donates electronsExpand

Chlorophyll formation and photosynthetic activity in rice mutants with alterations in hydrogenation of the chlorophyll alcohol side chain
Abstract The nuclear gene mutants M134 and M249 that accumulate chlorophyllides a and b esterified with incompletely reduced alcohol, such as geranylgeraniol, dihydrogeranylgeraniol, andExpand
