Contrasting effects of chronic heat stress and heat shock on kernel weight and flour quality in wheat

Abstract

Phytotron studies were conducted to compare the potential effects of chronic high-temperatures (daily maxima of over 20˚C) and heat-shock conditions (a few days of over 32˚C), on wheat (Triticum aestivum L.) yield and quality, to form a basis for the selection of improved high-temperature tolerance in wheat. The series of heat-shock treatments were designed to provide similar heat loads, by varying the duration (number of days) of each treatment. Studies involved two cultivars, Lyallpur and Trigo 1. Both showed a reduction in kernel weight in response to chronic high day temperatures (i.e. above 18˚C), with Trigo 1 more tolerant than Lyallpur. Kernel weight of both cultivars was also reduced by short periods of heat shock, and this was most evident at day/night temperatures above 30/25˚C. There was no reduction in the germination of the lighter weight kernels formed under either chronic high temperature or heat-shock conditions. Dough strength, as judged by mixing time, declined in both genotypes with prolonged chronic high temperature, and also following the most extreme of the heat-shock treatments - Trigo 1 showed an ability to resist these changes better than Lyallpur. The heat-related decreases in dough strength were assoc...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
