Systems analysis of guard cell membrane transport for enhanced stomatal dynamics and water use efficiency [PDF]

open access: yes, 2014
Stomatal transpiration is at the centre of a crisis in water availability and crop production that is expected to unfold over the next 20-30 years. Global water usage has increased 6-fold in the past 100 years, twice as fast as the human population, and ...

Climate Change Agricultural Comparative Advantage and the US Trade Balance

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT Current science indicates that warming and elevated atmospheric CO2 will have ambiguous results for crop productivity depending on crop type and geographic location, whereas increased heat stress makes livestock and human labor less productive.

Enhancing Surgical Efficiency and Cost‐Effectiveness With TaTME‐Combined Robot‐Assisted Surgery for Lower Rectal Cancer

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
ABSTRACT Background Robot‐assisted rectal surgery (RAS) offers improved dexterity and visualization; however, the high cost of equipment and consumables remains a major challenge for hospital management. At our institution, we have adopted a combined approach using transanal total mesorectal excision (TaTME) for lower rectal cancers, aiming to shorten ...

Impact of Body Weight Loss During Preoperative Chemoradiotherapy on Prognosis of Patients With Lower Rectal Cancer

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
The present study aimed to investigate the relationship between changes in body weight and composition during chemoradiotherapy, such as the psoas muscle mass index, visceral fat index, and subcutaneous fat index obtained from computed tomography images, and long‐term outcomes in rectal cancer patients.

With Over 60 Independent Losses, Stomata Are Expendable in Mosses

open access: yesFrontiers in Plant Science, 2020
Because stomata in bryophytes are uniquely located on sporangia, the physiological and evolutionary constraints placed on bryophyte stomata are fundamentally different from those on leaves of tracheophytes. Although losses of stomata have been documented

Characterizing the causes and consequences of calcium oxalate crystal presence in Vitis riparia

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Calcium oxalate biomineralization in plants is phylogenetically widespread and morphologically diverse, but the function of these inorganic crystals is an area of active debate. The variety of environmental conditions that produce the crystals, as well as the inconsistent evidence that they provide antiherbivore defense across plant ...

What is the influence of ordinary epidermal cells and stomata on the leaf plasticity of coffee plants grown under full-sun and shady conditions?

open access: yesBrazilian Journal of Biology
Stomata are crucial in land plant productivity and survival. In general, with lower irradiance, stomatal and epidermal cell frequency per unit leaf area decreases, whereas guard-cell length or width increases. Nevertheless, the stomatal index is accepted

Decreasing Transpiration of Field Plants by Chemical Closure of Stomata

open access: yesNature, 1964
CHEMICALS which close stomata have been described by Zelitch1. When sprayed on leaf surfaces, the compounds decrease transpiration and photosynthesis of detached leaves2 and of maize plants in soil3 by increasing the diffusion resistance of stomata.

Barley plasma membrane intrinsic proteins (PIP aquaporins) as water and CO2 transporters [PDF]

open access: yes, 2008
We identified barley aquaporins and demonstrated that one, HvPIP2;1, transports water and CO2. Regarding water homeostasis in plants, regulations of aquaporin expression were observed in many plants under several environmental stresses. Under salt stress,

Genetic Abnormalities and Clinical Management of Fetal Genitourinary System Anomalies in Eastern China

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT To investigate the correlation between genetic abnormalities and fetal genitourinary (GU) anomalies in Eastern China and to provide assistance for the clinical management of fetuses with different types of GU anomalies. Five hundred forty‐five fetuses with GU anomalies were enrolled, undergoing karyotyping, copy number variation sequencing ...
