Evaluation of freezing tolerance in chickpea promising genotypes (Cicer arietinum) using physiological traits and molecular markers [PDF]

open access: yesیافته‌های نوین در علوم زیستی, 2023
Chickpea is one of the most important plants of the legume family and is very important in the diet. In order to investigate the genetic diversity of chickpea, an experiment was conducted with 18 chickpea genotypes in the form of a completely to ...

Divergent thermal specialisation of two South African entomopathogenic nematodes [PDF]

open access: yesPeerJ, 2015
Thermal physiology of entomopathogenic nematodes (EPN) is a critical aspect of field performance and fitness. Thermal limits for survival and activity, and the ability of these limits to adjust (i.e., show phenotypic flexibility) depending on recent ...

Influence of Temperature on the Physiology and Virulence of the Insect Pathogen Serratia sp. Strain SCBI [PDF]

open access: yes, 2012
The physiology of a newly recognized Serratia species, termed South African Caenorhabditis briggsae Isolate (SCBI), which is both a nematode mutualist and an insect pathogen, was investigated and compared to that of Serratia marcescens Db11, a broad-host-

Prediction of the toxic effects of (agro) chemical mixtures on organisms using simple time-based models

open access: yesMethodsX, 2023
The lethal effect of a chemical acting alone can be predicted using the simple hyperbolic model, which relies on the chemicals' median lethal time (LT50).

Could natural selection change the geographic range limits of light brown apple moth (Lepidoptera, Tortricidae) in North America? [PDF]

open access: yes, 2013
We artificially selected for increased freeze tolerance in the invasive light brown apple moth. Our results suggest that, by not accounting for adaptation to cold, current models of potential geographic distributions could underestimate the areas at risk

The Effect of Repeated Low Temperature on Eggs of the Alfalfa Weevil (Coleoptera: Curculionidae) [PDF]

open access: yes, 2017
Three ages of alfalfa weevil, Hypera postica (Gyllenhal) eggs were exposed to repeated exposures of -15 and -20°C. Fresh-laid eggs were quite susceptible and 3- and 5day old eggs were relatively resistant to -15\u27C, but all ages of eggs showed ...

Characterisation of the ERF102 to ERF105 genes of Arabidopsis thaliana and their role in the response to cold stress [PDF]

open access: yes, 2020
The ETHYLENE RESPONSE FACTOR (ERF) genes of Arabidopsis thaliana form a large family encoding plant-specific transcription factors. Here, we characterise the four phylogenetically closely related ERF102/ERF5, ERF103/ERF6, ERF104 and ERF105 genes ...

Changing of the flower bud frost hardiness in three Hungarian apricot cultivars

open access: yesHorticultural Science, 2016
Hungary lies near the northern border of the apricot growing area, so frost hardiness is a decisive factor for the reliability of production. Both the development and loss of frost hardiness take place gradually in the overwintering organs, depending on ...

Helicoverpa armigera nucleopolyhedrovirus occlusion-derived virus-associated protein, HA100, affects oral infectivity in vivo but not virus replication in vitro [PDF]

open access: yes, 2011
ORF100 (ha100) of Helicoverpa armigera nucleopolyhedrovirus (HearNPV) has been reported as one of the unique genes of group II alphabaculoviruses encoding a protein located in the occlusion-derived virus (ODV) envelope and nucleocapsid.
