high temperature induced

Fungal cells are surrounded by a tight cell wall to protect them from harmful environmental conditions and to resist lysis. The synthesis and assembly determine the shape, structure, and integrity of the cell wall during the process of mycelial growth and development. High temperature is an important abiotic stress, which affects the …

However, the high temperature induced by titanium phase dry drilling will disperse into the interface and exceed the glass transition temperature of the resin matrix, promoting the thermal and mechanical damage of the CFRP holes [9], [11].

High temperature-induced hypocotyl elongation is a typical thermomorphogenesis trait that may significantly affect early seedling growth and subsequent crop yield. The ambient temperature and endogenous auxin are two critical factors that regulate hypocotyl growth. However, the mechanism of temperature and …

In this study, we report that irrigation treatment with melatonin (20 µM) effectively ameliorated high temperature-induced inactivation of pollen and inhibition of pollen germination in tomato (Solanum lycopersicum) plants. Melatonin alleviated reactive oxygen species production in tomato anthers under high temperature by the up …

High temperatures significantly injure the flowering, pollination, fruit growth, and quality of plants. Photosynthesis, the fundamental process supporting plant life, is crucial. Nevertheless, the quantitative evaluation of the physiological activity of the photosynthetic system of Nanfeng tangerine (NT) plants under high-temperature …

In this study, we report that irrigation treatment with melatonin (20 µM) effectively ameliorated high temperature-induced inactivation of pollen and inhibition of pollen germination in tomato ( Solanum lycopersicum) plants. Melatonin alleviated reactive oxygen species production in tomato anthers under high temperature by the up …

The period 66-72 h after pollination was the most suitable for high temperature-induced triploid production during embryo sac development in the 'Zheyin3#'. Cytological analysis showed that the ...

In some fish species, high or low temperature can switch the determination mechanisms and induce fish reversal when the gonads are undifferentiated. During this high or low temperature-induced reversal, the expressions of many genes are altered. However, genome-wide DNA methylation chang …

They found that TaXa21 is induced at high temperatures, providing temperature-enhanced stripe rust resistance in wheat seedlings. They found this occurs …

HT affects diverse cellular structures and functions like photosynthesis, transpiration, and respiration, which affect reproduction, phenology, and accelerates …

Moreover, high temperature-induced increases in Cu/Zn SOD and cAPX transcripts were significantly attenuated by the silencing of COMT1 gene, indicating that melatonin deficiency greatly affected transcription of antioxidant enzyme-related genes under high temperature stress.

Arabidopsis TCP4 transcription factor inhibits high temperature-induced homeotic conversion of ovules. Jingqiu Lan, # 1, 2 Ning Wang, # 1 Yutao Wang, 1 Yidan Jiang, 1 Hao Yu, 1 Xiaofeng Cao, 2 and Genji Qin 1 ... Abnormal high temperature (HT) caused by global warming threatens plant survival and food security, but the effects of …

To further explore the role of DNA methylation in high temperature-induced alteration of -related gene expressions, the transcripts of cyp19a1a, sox9b and esr1 were analyzed in zebrafish under high temperature and 5-AZA treatment. The results showed that 5-AZA partly recovered the reduced expression of these three genes …

However, changes in the m6A modification when early porcine embryos are exposed to stress remain unclear. In this study, we exposed porcine oocytes to a high temperature (HT, 41°C) for 10 h, after which the mature oocytes were parthenogenetically activated and cultured for 7 days to the blastocyst stage.

A mean of 68.24 M high-quality clean reads was obtained for each library. Differentially expressed genes (DEGs) between different sexes and environmental treatments were identified, revealing that the heat shock protein gene family was involved in the high temperature induced reversal.

Subsequently, embryonic exposure to temperature-induced stress up-regulated the genes related to the thyroid and stress axes with a final increase in T3 levels. In this context, we show that blocking the stress axis response by the loss of function of the corticotropin-releasing hormone receptors suppresses thyroid-stimulating hormone ...

High temperature stress was induced from flower initiation to maturity stage by keeping the pots in a temperature controlled green house facility for 45 days. The quality and yield parameters were taken at the harvesting stage. Starch and soluble sugar concentration in the leaves of tomato genotypes showed significant reduction in its …

High temperature can induce the production of 2n gametes and aborted pollen during microsporogenesis in Populus canescens. However, the mechanism by which high temperature induces pollen abortion remains unknown. Here, pollen abortion was induced by exposing male flower buds of P. canescens to 38 and 41 °C; pollen …

It can be seen that the treatment conditions of high temperature-induced forest trees to form 2n pollen may be related to the adaptation of tree species for the high temperature environment. The formation of 2n gametes is closely related to chromosomal behaviour and cell division ( Camadro et al., 2008 ; Brownfield and Khler, 2011 ).

Harvested banana fruit ripened under warm temperatures above 24 °C remain green peel, leading to severe economic loss. E3 ubiquitin-ligases, as the major components in the ubiquitination pathway, have been implicated to play important roles in temperature-stress responses. However, the molecular mechanism underlying high …

Environmental changes alter the fate in about 15% of vertebrate orders, mainly in ectotherms such as fish and reptiles. However, the effects of temperature changes on the endocrine and molecular processes controlling gonadal determination are not fully understood. Here, we provide evidence that thyroid hormones (THs) act as …

In contrast, the expression of PIF4 was similarly induced by high-temperature exposure in wild type and ML1p::PHYB;phyB-9 transgenic plants (Fig. 4d). Taken together, these results suggest that ...

High temperature-induced generation of sterile pollen due to higher accumulation of ROS, such as hydroxyl radicals (•OH), superoxide anion (O 2 • −) and hydrogen peroxide (H 2 O 2), which induce lipid peroxidation and oxidation of nucleic acids, sugars and proteins, ultimately results in pollen and anther cell death [8,16]. Antioxidant ...

However, it is unknown if epigenetic control of cyp19a1a expression is critical for high temperature induced masculinization in the freshwater fish Nile tilapia. We analyzed the cyp19a1a DNA methylation levels in three age groups and found that they were lower in females than in males. At 8 months of age, males had DNA methylation levels of the ...
