Effects of stomatal development on stomatal conductance and on stomatal limitation of photosynthesis in Syringa oblata and Euonymus japonicus Thunb

Plant Science, 2014
During leaf development, the increase in stomatal conductance cannot meet photosynthetic demand for CO2, thus leading to stomatal limitation of photosynthesis (Ls). Considering the crucial influences of stomatal development on stomatal conductance, we speculated whether stomatal development limits photosynthesis to some extent. To test this hypothesis,

Short‐Term Outcomes and Cost Drivers of Emergency Surgery for Acute Abdominal Disease in Super‐Elderly Patients: A Study in the Japanese Tertiary Care Hospital

Annals of Gastroenterological Surgery, EarlyView.
This retrospective study analyzed patients aged ≥ 85 years undergoing emergency abdominal surgery, focusing on short‐term outcomes and inpatient cost structure under the Japanese DPC system. Although major complications occurred in 19.4% of patients, more than 70% were discharged home.

Forest response and recovery following disturbance in upland forests of the Atlantic Coastal Plain

Frontiers in Plant Science, 2014
Carbon and water cycling of forests contribute significantly to the Earth’s overall biogeochemical cycling and may be affected by disturbance and climate change.

Linking xylem hydraulic conductivity and vulnerability to the leaf economics spectrum--a cross-species study of 39 evergreen and deciduous broadleaved subtropical tree species. [PDF]

PLoS ONE, 2014
While the fundamental trade-off in leaf traits related to carbon capture as described by the leaf economics spectrum is well-established among plant species, the relationship of the leaf economics spectrum to stem hydraulics is much less known.

A hydromechanical and biochemical model of stomatal conductance [PDF]

Plant, Cell & Environment, 2003
ABSTRACTA mathematical model of stomatal conductance is presented. It is based on whole‐plant and epidermal hydromechanics, and on two hypotheses: (1) the osmotic gradient across guard cell membranes is proportional to the concentration of ATP in the guard cells; and (2) the osmotic gradient that can be sustained per unit of ATP is proportional to the ...

Single‐Incision Laparoscopy‐First Strategy in Crohn's Disease: Risk Factors for Conversion and Surgical Outcomes

Annals of Gastroenterological Surgery, EarlyView.
In this retrospective study of 289 patients with Crohn's disease undergoing a single‐incision laparoscopy‐first (SILS‐first) strategy, conversion to open surgery was required in only 11.8% of cases. Fistula formation, colon resection, and smoking history were identified as independent risk factors for conversion, while postoperative complications and ...

Enabling the study of gene function in gymnosperms: Virus‐induced gene silencing in Ephedra tweedieana

Applications in Plant Sciences, EarlyView.
Abstract Premise As the sister clade to angiosperms, extant gymnosperms are crucial for reconstructing ancestral gene regulatory networks in seed plants. This highlights the need for model systems representing each of their distinct lineages. However, tools to quickly and effectively investigate gene function in gymnosperms are still limited due to the

A Bayesian information theoretic approach to assessing stomatal conductance dynamics in a perennial agricultural crop

Ecological Indicators
Perennial grain crops have been proposed as a more sustainable alternative to annual counterparts given their potential to replicate natural ecosystem services when managed correctly while requiring less external input than annual agriculture.

Pore size regulates operating stomatal conductance, while stomatal densities drive the partitioning of conductance between leaf sides [PDF]

Annals of Botany, 2014
Leaf gas exchange is influenced by stomatal size, density, distribution between the leaf adaxial and abaxial sides, as well as by pore dimensions. This study aims to quantify which of these traits mainly underlie genetic differences in operating stomatal conductance (gs) and addresses possible links between anatomical traits and regulation of pore ...
