Reflectance spectroscopy predicts leaf functional traits across wine grape cultivars

PLANTS, PEOPLE, PLANET, EarlyView.
Characterizing variability in crop traits is key for understanding agroecosystem responses to environmental change. However, trait data are often time‐consuming to collect and therefore still limit our understanding and predictions of agriculture responses to environmental change.

Incremental Grid-like Layout Using Soft and Hard Constraints [PDF]

, 2013
We explore various techniques to incorporate grid-like layout conventions into a force-directed, constraint-based graph layout framework. In doing so we are able to provide high-quality layout---with predominantly axis-aligned edges---that is more ...

Structural Studies of Ribulose 1,5-Bisphosphate Carboxylase/Oxygenase

, 1978
From studies of three crystal forms of ribulose bisphosphate (RuBP) carboxylase from Nicotiana tabacum (called I, II, and III), we have determined the subunit organization of RuBP carboxylase in increasing detail. Combined x-ray diffraction and electron microscope data from these crystals show that there must be some multiple of eight polypeptide ...

Growth inhibition of arable weeds by cerato‐platanin, a plant immune defense activator of fungal origin

Pest Management Science, EarlyView.
Plants possess an innate immune system able to detect pathogens' molecules such as cerato‐platanin (CP), a protein produced by the fungus Ceratocystis platani. This study shows that the application of this protein elicitor to weeds can be exploited as a novel herbicide mode of action.

Regulation of the cyanobacterial CO2-concentrating mechanism involves internal sensing of NADP+ and α-ketogutarate levels by transcription factor CcmR. [PDF]

PLoS ONE, 2012
Inorganic carbon is the major macronutrient required by organisms utilizing oxygenic photosynthesis for autotrophic growth. Aquatic photoautotrophic organisms are dependent upon a CO(2) concentrating mechanism (CCM) to overcome the poor CO(2)-affinity of

Does Leaf Position within a Canopy Affect Acclimation of Photosynthesis to Elevated CO2? . Analysis of a Wheat Crop under Free-Air CO2 Enrichment [PDF]

, 1998
Previous studies of photosynthetic acclimation to elevated CO2 have focused on the most recently expanded, sunlit leaves in the canopy. We examined acclimation in a vertical profile of leaves through a canopy of wheat (Triticum aestivum L.). The crop was

Rubisco catalytic properties and temperature response in crops. [PDF]

, 2016
Rubisco catalytic traits and their thermal dependence are two major factors limiting the CO2 assimilation potential of plants. In this study, we present the profile of Rubisco kinetics for twenty crop species at three different temperatures.

Elimination of the Chlamydomonas gene family that encodes the small subunit of ribulose-1,5-bisphosphate carboxylase/oxygenase.

Proceedings of the National Academy of Sciences of the United States of America, 1996
Ribulose-1,5-bisphosphate carboxylase/ oxygenase (EC 4.1.1.39) is the key photosynthetic enzyme that catalyzes the first step of CO2 fixation. The chloroplast-localized holoenzyme of plants and green algae contains eight nuclear-encoded small subunits ...

Ribulose-1,5-Bisphosphate Carboxylase/Oxygenase Activase Protein Prevents the in Vitro Decline in Activity of Ribulose-1,5-Bisphosphate Carboxylase/Oxygenase [PDF]

Plant Physiology, 1989
The rate of CO(2) fixation by ribulose-1,5-bisphosphate carboxylase/oxygenase (rubisco) following addition of ribulose 1,5-bisphosphate (RuBP) to fully activated enzyme, declined with first-order kinetics, resulting in 50% loss of rubisco activity after 10 to 12 minutes.
