The increased probability of occurrence of more intense and frequent heat stress episodes and extended warmer nights in the future are major challenges towards sustaining agricultural production. Cereals, millets and oil seed crops respond differently to increasing temperature at different growth and developmental stages but are highly susceptible to heat stress during the gametogenesis and the flowering stages. Interestingly, the duration of stress exposure induces differential responses i.e. season-long exposure to hightemperature and short episodes of heat stress coinciding with reproductive processes. Season-long high-temperature stress decreased biomass production, seed number, individual seed weight and yield of all grain crops. Short duration heat stress coinciding with either gametogenesis or anthesis leads to negative impact of seed-set, while stress exposure at post-anthesis stages decreased seed filling duration leading to decreased seed weight. Based on extensive research we have identified temperature thresholds across field crops and quantified the above changes. Impact of heat stress on pollen production, pollen viability, pollen lipid profiles, alternations in the pollen and stigmatic surface, pollen reactive oxygen species production, their membrane damage etc., differentiating contrasting cultivars across different field crops will be highlighted. In addition, considering the differential rate of increase in minimum night temperature, different physiological routes inducing yield losses under high day and high night temperature will be presented. Genetic variability across field crops in response to heat stress and more interestingly options from wild species of wheat (higher heat tolerance at flowering), rice (heat escape through early morning flowering) and their usefulness in heat stress tolerance breeding will be an interesting addition to our talk. The current progress achieved, opportunities available, unaddressed challenges and future direction of research that could help in crop improvement to sustain global food production under future hotter climates will be discussed.

Abstract High night-time temperature (HNT) disturbs processes of both assimilate production (source) and assimilate accumulation (sink), and as a result substantially reduces yields of cereal crops. There have been reports that increasing nitrogen application can alleviate the negative impact of high-temperature stress on yield in rice ( Oryza sativa L.). However, little is known about the interactive effect of HNT and nitrogen (N) supply on rice grain yield and its underlying source-sink relati...

High night temperature (HNT) is a major constraint to sustaining global rice production under future climate. Physiological and biochemical mechanisms were elucidated for HNT-induced grain yield and quality loss in rice. Contrasting rice cultivars (N22, tolerant; Gharib, susceptible; IR64, high yielding with superior grain quality) were tested under control (23°C) and HNT (29°C) using unique field-based tents from panicle initiation till physiological maturity. HNT affected 1000 grain weight, gr...

Abstract Global climate models predict increase in mean daily temperature to be mainly driven by rapid increase in nighttime temperature compared to daytime temperature, leading to narrowing diurnal temperature amplitude. Higher day and night temperatures induce significant negative impact on growth and development of different crops. However, limited studies have focused on quantifying impacts associated with different diurnal temperature amplitudes maintaining the same daily mean temperature. ...

Wheat (Triticum aestivum L.) and barley (Hordeum vulgare L.) crops are exposed to warm nights during their growing seasons and this trend is unlikely to change. The aim of this work was to evaluate the effect of higher post-anthesis night temperatures on field-grown crop yield, focusing on final grain weight determination. Experiments combined: (i) two well-adapted crops with similar phenology: bread wheat and two-row malting barley, under (ii) two temperature regimes: ambient and high night tem...

Experiments were conducted over two years to quantify the response of faba bean (Vicia faba L.) to heat stress. Potted winter faba bean plants (cv. Wizard) were exposed to temperature treatments (18/10; 22/14; 26/18; 30/22; 34/26°C day/night) for five days during floral development and anthesis. Developmental stages of all flowers were scored prior to stress, plants were grown in exclusion from insect pollinators to prevent pollen movement between flowers, and yield was harvested at an individua...

AbstractThe rising temperatures are resulting in heat stress for various agricultural crops to limit their growth, metabolism, and leading to significant loss of yield potential worldwide. Heat stress adversely affects normal plant growth and development depending on the sensitivity of each crop species. Each crop species has its own range of temperature maxima and minima at different developmental stages beyond which all these processes get inhibited. The reproductive stage is on the whole more...

Rice is one of the main food crops in the world. In the near future, yield is expected to be under pressure due to unfavorable climatic conditions, such as increasing temperatures. Therefore, improving rice germplasm in order to guarantee rice production under harsh environmental conditions is of top priority. Although many physiological studies have contributed to understanding heat responses during anthesis, the most heat-sensitive stage, molecular data are still largely lacking. In this study...

Main conclusion Heat stress changes isoform content and distribution of cytoskeletal subunits in pollen tubes affecting accumulation of secretory vesicles and distribution of sucrose synthase, an enzyme involved in cell wall synthesis. Plants are sessile organisms and are therefore exposed to damages caused by the predictable increase in temperature. We have analyzed the effects of temperatures on the development of pollen tubes by focusing on the cytoskeleton and related processes, such as vesi...

Abstract Maize yield has to be increased in the next decades in order to satisfy world demand. This increase has to be achieved in a scenario of climate change particularly characterised by heat stress. Several agronomic and genetic strategies for increased tolerance to high temperatures will be necessary. Some results in other crops showed interactions between high temperature stress and nitrogen (N) availability. To the best of our knowledge, this interaction has not been tested in maize. Ther...

Increasing food demand under climate change constraints may challenge and strain agricultural systems. The use of crop models to assess genotypes performance across diverse target environments and management practices, i.e. the genetic x environment x management interaction (GEMI), can help understand genotype and agronomic practices suitability and possibly accelerate turnaround in plant breeding programs. However, the readiness of models to support these tasks can be debated. In this article w...

Abstract The increased incidence of extreme temperature events due to global climate change poses a major challenge for crop production. Ability to increase temperature tolerance through genetic improvement requires understanding of how crops and their wild relatives respond to extreme temperatures. We developed a high-throughput technique to evaluate tolerance to freezing stress (FS) and heat stress (HS) in wild, crop–wild hybrid and cultivated sunflower (Helianthus annuus L.). We also investig...

High-temperature stress induces cellular changes leading to over-production of highly reactive oxygen species (ROS) which damage macromolecules and cell organelles, eventually resulting in cell death. Antioxidative metabolism in plants comprising of enzymatic and non-enzymatic antioxidants imparts tolerance by scavenging or detoxification of excess ROS. We investigated the response of major H2O2-detoxifying system, the AsA–GSH cycle in four genotypes of maize differing in heat sensitivity. Stres...

Heat stress during flowering has differential impact on male and female reproductive organ viability leading to yield losses in field crops. Unlike flooded rice, dryland cereals such as sorghum, pearl millet and wheat have optimised their flower opening during cooler early morning or late evening hours to lower heat stress damage during flowering. Although previous studies have concluded that pollen viability determines seed set under heat stress, recent findings have revealed pearl millet and s...

Rice holds the key to future food security. In rice-growing areas, temperature has already reached an optimum level for growth, hence, any further increase due to global climate change could significantly reduce rice yield. Several mapping studies have identified a plethora of reproductive tissue-specific and heat stress associated inconsistent quantitative trait loci (QTL), which could be exploited for improvement of heat tolerance. In this study, we performed a meta-analysis on previously repo...

Abstract Wheat production is expected to be challenged by future climate change. However, it is unclear how wheat grown in diverse agroecologies will respond to climate change and adaptation management strategies. A geospatial simulation study was conducted to understand the impacts of climate change and adaptation management strategies on wheat (Triticum aestivum L.) production in Ethiopia. Simulation results showed that the average long-term baseline (1980–2005) wheat yield ranged from 1593 to...

Unravelling the metabolic and phytohormonal changes in anthers exposed to heat stress would help identify mechanisms regulating heat stress tolerance during the sensitive reproductive stage. Two spring wheat genotypes contrasting for heat tolerance were exposed to heat stress during heading in controlled environment chambers. Anthers were collected from main and primary spikes for metabolic and phytohormonal profiling. A significant reduction in seed set (38%), grain number (54%) and grain weigh...
