Spatial and Temporal Dynamics of Photosynthetically Active Radiation in Crops: Effects of Canopy Structure on Yield

Agronomy
Understanding the spatial–temporal distribution of photosynthetically active radiation (PAR) within crop canopies is crucial for optimizing planting structures to enhance resource use efficiency and improve crop yields.

Intraoperative Collection of Ascitic Fluid With Intra‐ or Postoperative Reinfusion in Ovarian Cancer: Safety and Feasibility of a Roller Pumping Method

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Patients with ovarian cancer often present with massive ascites, leading to significant protein loss during surgical procedures. Although cell‐free concentrated ascites reinfusion therapy (CART) is used in palliative settings to mitigate protein loss, its application in intraoperative settings remains unexplored.

Mid-Season Leaf Glutamine Predicts End-Season Maize Grain Yield and Nitrogen Content in Response to Nitrogen Fertilization under Field Conditions

Agronomy, 2017
After uptake in cereal crops, nitrogen (N) is rapidly assimilated into glutamine (Gln) and other amino acids for transport to sinks. Therefore Gln has potential as an improved indicator of soil N availability compared to plant N demand. Gln has primarily

Plant Growth Parameters in Pea under Different Plant Densities

, 2023
Pea (Pisum sativum L.) is belongs to the Leguminosae family and currently grown in most temperate regions of the world. The research was carried out between February and June 2022 in the Dicle University, Faculty of Agriculture, in Diyarbakır, Turkey. In the experiment, four different plant densities (40, 60, 80, 100 seeds per square meters) were used ...

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM

FEBS Letters, EarlyView.
Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

The impact of location, row direction, plant density and rootstock on the sunburn damage of apple cultivars

International Journal of Horticultural Science, 2005
The effect of row direction (N-S, E-W), plant density (conventional and intensive) and rootstock (M9, MM106 and crab apple) on the sensitivity of 41 apple cultivars to sunburn injury was studied at 6 locations (Derecske, Kálmánáaza, Nagykutas, Nagylapos,

Integrated readings for the urban green roof. Expressive codes and forms of nature

Agathón, 2022
The quality of public space requires new study paradigms: interconnected pieces of a broader urban green system can guarantee ecosystem services and liveability to spaces full of cultural meaning and social attraction. In particular, green roof gardens,

Simulating Root Density Dynamics and Nitrogen Uptake -Field Trials and Root Model Approach in Denmark [PDF]

, 2007
Plant soil and atmosphere models are commonly used to predict crop yield and associated environmental consequences. Such models often include complex modelling of water movement, soil organic matter turnover and above ground plant growth.

Mapping the evolution of mitochondrial complex I through structural variation

FEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Impact of river management history on the community structure, species composition and nutrient status in the Rhine alluvial hardwood forest [PDF]

, 1998
The present-day Rhine alluvial hardwood forest (Querco-Ulmetum minoris, Issler 24) in the upper Rhine valley (France/Germany) is comprised of three vegetation units, one still flooded by calm waters (F) and the two others unflooded, one for 30 years ...
