Evaluating Water–Energy–Food Nexus Strategies to Address Resource Scarcity in the Crocodile River Catchment, South Africa

open access: yesIrrigation and Drainage, EarlyView.
ABSTRACT The water–energy–food (WEF) nexus approach highlights the interdependence of water, energy and food resources, all of which play central roles in agriculture, especially irrigation. A WEF nexus lens was applied to Mpumalanga's Crocodile River catchment, a vital irrigation area that significantly contributes to South Africa's staple food ...

Remote Sensing for Irrigation Water Management—The State of the Art and Prospects for Near‐Future Operations

open access: yesIrrigation and Drainage, EarlyView.
ABSTRACT A recent UN report describes many regions as facing ‘water bankruptcy,’ a condition in which available water resources can no longer meet existing demands. In practice, this means irrigation will likely bear the greatest burden of future water‐use reductions, a complicated and fraught decision to make given its critical role in food security ...

Molecular battles between plant and pathogenic bacteria in the phyllosphere

open access: yesBrazilian Journal of Medical and Biological Research, 2010
The phyllosphere, i.e., the aerial parts of the plant, provides one of the most important niches for microbial colonization. This niche supports the survival and, often, proliferation of microbes such as fungi and bacteria with diverse lifestyles ...

Land‐Atmosphere Coupling Is Associated With Severer Vegetation Productivity Losses During Compound Dry‐Hot Events in Drylands

open access: yesInternational Journal of Climatology, EarlyView.
Compound dry‐hot events (CDHEs) exerted severer damage on vegetation productivity for temperate shrublands, savannas and grasslands in drylands. Land‐atmosphere coupling was associated with severer negative impacts of CDHEs through soil moisture–temperature feedback, especially for dry‐event‐leading CDHEs.

How does the nectar of stomata-free nectaries cross the cuticle?

open access: yesActa Botânica Brasílica
In many glandular structures, departure from the cell is only one step in the process of exudate release to the plant surface. Here the set of events that lead nectar to the external environment is presented and discussed mainly for stomata-free ...

Wheat Wild Relatives and Modern Cultivars Differ for Salt Resistance in Terms of Morpho‐Physiological Traits

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
Wheat wild relatives are untapped genetic resources from salinity and drought hit areas. This study presents differential comparative morphophysiological responses of these species and modern wheat cultivars under saline conditions. Salt resistant species produce more shoot and root biomass under saline conditions through salt exclusion and/or tissue ...

An optimization method for measuring the stomata in cassava (Manihot esculenta Crantz) under multiple abiotic stresses

open access: yesOpen Life Sciences
As a gateway for gas exchange, pores regulate the transport of air and water in carbon assimilation, respiration, and transpiration to quickly adapt to environmental changes.

Effects of Microplastic Pollution on Growth, Photosynthesis, and Nutritional Composition of Maize (Zea mays L.)

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background Microplastic (MP) contamination in agroecosystems is an increasingly recognized environmental concern, whereas its polymer‐specific impacts on plant growth and nutritional composition remain poorly understood. Aim Our study aimed to evaluate how polymer type and concentration of MPs directly affect plant growth, physiological traits,

Plant basal resistance: genetics, biochemistry, and impacts on plant-biotic interactions [PDF]

open access: yes, 2012
Basal resistance depends largely on a diverse range of defence mechanisms that become active upon attack by pathogens or insects. These mechanisms range from rapid stomatal closure and production of reactive oxygen species, to callose deposition and ...
