Comparison of dilute acid and ionic liquid pretreatment of switchgrass: Biomass recalcitrance, delignification and enzymatic saccharification.
The efficiency of two biomass pretreatment technologies, dilute acid hydrolysis and dissolution in an ionic liquid, are compared in terms of delignification, saccharification efficiency andExpand

The Selaginella Genome Identifies Genetic Changes Associated with the Evolution of Vascular Plants
The genome sequence of a lycophyte hints at ancient evolutionary transitions. Vascular plants appeared ~410 million years ago, then diverged into several lineages of which only two survive: theExpand

The PSI-H subunit of photosystem I is essential for state transitions in plant photosynthesis
Photosynthesis in plants involves two photosystems responsible for converting light energy into redox processes. The photosystems, PSI and PSII, operate largely in series, and therefore theirExpand

Balance of power: a view of the mechanism of photosynthetic state transitions.
Photosynthesis in plants involves photosystem I and photosystem II, both of which use light energy to drive redox processes. Plants can balance the distribution of absorbed light energy between theExpand

ARABINAN DEFICIENT 1 Is a Putative Arabinosyltransferase Involved in Biosynthesis of Pectic Arabinan in Arabidopsis1[W]
The function of a putative glycosyltransferase (At2g35100) was investigated in Arabidopsis (Arabidopsis thaliana). The protein is predicted to be a type 2 membrane protein with a signal anchor. TwoExpand

Nearest-Neighbor Analysis of Higher-Plant Photosystem I Holocomplex
Photosystem I (PSI) preparations from barley (Hordeum vulgare) and spinach (Spinacia oleracea) were subjected to chemical cross-linking using the cleavable homobifunctional cross-linkersExpand

Xylan biosynthesis.
Plant cells are surrounded by a rigid wall made up of cellulose microfibrils, pectins, hemicelluloses, and lignin. This cell wall provides structure and protection for plant cells. In grasses and inExpand

The PSI-K Subunit of Photosystem I Is Involved in the Interaction between Light-harvesting Complex I and the Photosystem I Reaction Center Core*
PSI-K is a subunit of photosystem I. The function of PSI-K was characterized in Arabidopsis plants transformed with a psaK cDNA in antisense orientation, and several lines without detectable PSI-KExpand

Arabidopsis CHL27, located in both envelope and thylakoid membranes, is required for the synthesis of protochlorophyllide
CHL27, the Arabidopsis homologue to Chlamydomonas Crd1, a plastid-localized putative diiron protein, is required for the synthesis of protochlorophyllide and therefore is a candidate subunit of theExpand

Photoinhibition of photosystem I
Photosystem I (PSI) is a large pigment-protein complex consisting of about 18 different subunits in plants. Recently, the structure of PSI isolated from pea was solved by X-ray crystallography at aExpand
