“…There are genetic differences in the sensitivity of spikelets to HS (Buu et al, 2021). Spikelet's from heattolerant genotypes show better results than sensitive ones under HS (Jagadish et al, 2010;Prasad et al, 2006).…”

“…A list of QTLs related to heat-stress tolerance is given in Table 2. Development of transgenic rice tolerant cultivars Heat shock proteins are synthesized by many genetic factors (Buu et al, 2021) that switch on when exposed to HS and play critical roles in the recovery of plants after HS (Liu et al, 2006;Nakamoto and Hiyama, 1999). Alterations in transgenic rice associated with HSPs have the potential to increase HS tolerance in rice (Zou et al, 2011).…”

Rice is an important cereal crop worldwide that serves as a dietary component for half of the world’s population. Climate change, especially global warming is a rising threat to crop production and food security. Therefore, enhancing rice growth and yield is a crucial challenge in stress-prone environments. Frequent episodes of heat stress threaten rice production all over the world. Breeders and agronomists undertake several techniques to ameliorate the adverse effects of heat stress to safeguard global rice production. The selection of suitable sowing time application of plant hormones, osmoprotectants and utilization of appropriate fertilizers and signaling molecules are essential agronomic practices to mitigate the adverse effects of heat stress on rice. Likewise, developing genotypes with improved morphological, biochemical, and genetic attributes is feasible and practical way to respond to this challenge. The creation of more genetic recombinants and the identification of traits responsible for heat tolerance could allow the selection of early-flowering cultivars with resistance to heat stress. This review details the integration of several agronomic, conventional breeding, and molecular approaches like hybridization, pure line selection, master-assisted-selection (MAS), transgenic breeding and CRRISPR/Cas9 that promise rapid and efficient development and selection of heat-tolerant rice genotypes. Such information’s could be used to determine the future research directions for rice breeders and other researchers working to improve the heat tolerance in rice.

“…Global warming is occurring all over the world and the Intergovernmental Panel on Climate Change (IPCC) observed a 0.3 o C rise in temperatures every 10 years. Some studies indicate that if temperatures increase by 1 o C, rice yields would decrease by 10% (BUU et al, 2021), whereas others esti mate that the increasing temperature could reduce rice producti on by 41% at the end of the 21 st century (KHAN et al, 2019). Heat stress has become increasingly important as a yield-limiti ng factor and the increased frequency of shortterm but extremely high temperatures is parti cularly damaging (BUU et al, 2021).…”

O objetivo deste trabalho foi avaliar o efeito do estresse térmico (calor) na antese sobre o desempenho agronômico de genótipos brasileiros modernos de arroz irrigado. As variedades SCS124 Sardo, SCS122 Miura, SCS121 CL, SCS116 Satoru, SCSBRS Tio Taka, Epagri 109 e as linhagens SC 491 ME, SC 676, SC 792, SC 806, SC 817, SC 849 foram avaliadas. Na antese, as plantas correspondentes ao tratamento de estresse por calor foram transferidas para uma câmara de crescimento por quatro dias sob temperaturas de 38ºC (dia) e 30ºC (noite). Em seguida, voltaram à casa de vegetação, onde permaneceram até a colheita sob 25ºC aproximadamente. A esterilidade de espiguetas variou de 4,0 a 84,1%. A produtividade variou de 10,2 a 101,2g pl-1. O estresse térmico aumentou a esterilidade das espiguetas e diminuiu a produção de grãos. As linhagens SC 817 e 806 apresentaram menor porcentagem de esterilidade de espiguetas e maior produção sob estresse de calor, sendo, portanto, genótipos promissores para gerar cultivares tolerantes a altas temperaturas na antese.

“…Global warming not only enhances the mean temperature but also intensifies the frequency and severity of heat stress events in rice-growing regions [2,3], where the present temperature is already close to the critical threshold level for rice production [4,5]. Consequently, any further increase in temperature beyond the threshold levels, particularly during critical growth stages, will cause significant grain yield losses [1,6,7].…”

Extreme temperature events as a consequence of global climate change result in a significant decline in rice production. A two-year phytotron experiment was conducted using three temperature levels and two heating durations to compare the effects of heat stress at booting, flowering, and combined (booting + flowering) stages on the production of photosynthates and yield formation. The results showed that high temperature had a significant negative effect on mean net assimilation rate (MNAR), harvest index (HI), and grain yield per plant (YPP), and a significant positive effect under treatment T3 on mean leaf area index (MLAI) and duration of photosynthesis (DOP), and no significant effect on biomass per plant at maturity (BPPM), except at the flowering stage. Negative linear relationships between heat degree days (HDD) and MNAR, HI, and YPP were observed. Conversely, HDD showed positive linear relationships with MLAI and DOP. In addition, BPPM also showed a positive relationship with HDD, except at flowering, for both cultivars and Wuyunjing-24 at combined stages. The variation of YPP in both cultivars was mainly attributed to HI compared to BPPM. However, for biomass, from the first day of high-temperature treatment to maturity (BPPT-M), the main change was caused by MNAR followed by DOP and then MLAI. The projected alleviation effects of multiple heat stress at combined stages compared to single-stage heat stress would help to understand and evaluate rice yield formation and screening of heat-tolerant rice cultivars under current scenarios of high temperature during the rice-growing season.
