DigR : how to model root system in its environment? 1 - the model [PDF]

, 2011
Many models already exist through literature dealing with root system representation, among which pure structure models such as Root Typ (Pagès 2004), SimRoot (Lynch 1997), AmapSim (Jourdan 1997); diffusion PDE models (Bastian 2008; Bonneu 2009) and ...

Self-Assembling Peptide Detergents Stabilize Isolated Photosystem Ion a Dry Surface for an Extended Time [PDF]

, 2005
We used a class of designed peptide detergents to stabilize photosystem I (PS-I) upon extended drying under N(2) on a gold-coated-Ni-NTA glass surface.

When chemistry meets taxonomy: Studying glycolipidic chemomarkers in pelagic Sargassum spp. (Phaeophyceae) using molecular networking

Journal of Phycology, EarlyView.
Abstract To chemically differentiate the three pelagic Sargassum morphotypes co‐occurring in floating rafts and drifting across the Atlantic Ocean before stranding on West African, Caribbean, and Atlantic Mexican coastlines, we conducted an investigation of their metabolomic profiles.

Ultrastructural changes in chloroplasts of mesophyll cells of chlorotic and prematurely yellowed leaves of Betula pendula Rothr

Acta Societatis Botanicorum Poloniae, 2011
The ultrastructure of chloroplasts was studied in mesophyll cells of the leaves of silver birch (Betula pendula) showing interveinal chlorosis or premature yellowing, in comparison with leaves without symptoms or exhibiting symptoms of natural senescence.

Characterisation of a chlororespiratory pathway in Beta vulgaris and Trifolium repens : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Plant Biology at Massey University, New Zealand [PDF]

, 2002
The chloroplast respiratory pathway (chlororespiration) is postulated to interact with the photosynthetic pathway through the plastoquinone (PQ) pool. Two enzymes are proposed to operate in the pathway: an NAD(P)H dehydrogenase that is homologous to the ...

Starch synthesis in Brachypodium distachyon endosperm occurs in dynamic, connected amyloplast compartments

New Phytologist, EarlyView.
Summary The morphology of starch granules is a major determinant of the functional and nutritional properties of starch and is highly variable among cereal species. Much of this morphological variation stems from differences in the spatial and temporal patterns of starch granule initiation in amyloplasts during grain development.

Correlation between spatial (3D) structure of pea and bean thylakoid membranes and arrangement of chlorophyll-protein complexes

BMC Plant Biology, 2012
Background The thylakoid system in plant chloroplasts is organized into two distinct domains: grana arranged in stacks of appressed membranes and non-appressed membranes consisting of stroma thylakoids and margins of granal stacks.

Phytosulfokine signalling blocks mycotoxin toxicity in Arabidopsis and mediates suppression of cell death activated by bacterial microbe‐associated molecular patterns

New Phytologist, EarlyView.
Summary Fumonisin B1 (FB1) is a mycotoxin that disrupts ceramide biosynthesis and kills plants. Prior activation with bacterial microbe‐associated molecular patterns (MAMPs), such as components of bacterial flagella, effectively suppresses FB1‐induced cell death.

Quantifying and monitoring functional Photosystem II and the stoichiometry of the two photosystems in leaf segments: Approaches and approximations [PDF]

, 2015
Given its unique function in light-induced water oxidation and its susceptibility to photoinactivation during photosynthesis, photosystem II (PS II) is often the focus of studies of photosynthetic structure and function, particularly in environmental

Rice MGD1‐Mediated Improvement of Photosynthesis and Crop Yield by Flexible Adaptation to Different Light Conditions

Plant Biotechnology Journal, EarlyView.
ABSTRACT Flexible adaptation to different light intensities found in natural environments is crucial for efficient photosynthesis and yield production in crops. The ability to cope with suboptimal light conditions effectively and efficiently is clearly advantageous.
