“…Moreover, many studies on warmseason crop plants such as rice, sorghum, and soybean demonstrate temperatures in the mid-to-upper 30s • C result in reduced yields that are highly correlated with declines in pollen production as well as viability as indicated by viability stains and assessment of in vitro and in vivo pollen tube growth (Matsui et al, 1997;Prasad et al, 1999Prasad et al, , 2001Prasad et al, , 2002Prasad et al, , 2003Prasad et al, , 2006bDjanaguiraman et al, 2013;Maruyama et al, 2013;Prasad and Djanaguiraman, 2014;Singh et al, 2015). This severity of the impact of HT on male reproduction and crop yields is best illustrated in rice where high day (≥32 • C) and night (≥29 • C) temperatures drastically reduce or eliminate yields solely through their negative effect on one or more of the sensitive stages of male reproduction (Satake and Yoshida, 1978;Peng et al, 2004;Shah et al, 2011;Laborte et al, 2012;Teixeira et al, 2012;Bagha, 2014;Nguyen et al, 2014). Notably, the major rice growing regions currently experience both high day and night temperatures during flowering ( Fig.…”

“…Under such high temperatures, microspores are aborted and pollen viability is reduced during anthesis, subsequently causing spikelet sterility (Cheng et al 2009;Mohammed and Tarpley 2009a, 2009b. The relationship between heat stress and spikelet sterility has been reported in rice (Nguyen et al 2013;Oort et al 2014) and other crop species (Oshino 2007;Sakata et al 2008). As demonstrated in several investigations, HTS can severely alter the morphology, structure, and functions of male gametophytes.…”

Temperatures that extend beyond normal levels of tolerance cause severe stress to plants, especially during the reproductive and grain filling/ripening stages. Heat stress leads to serious yield losses in many crop plants, including rice (Oryza sativa). In view of the current scenario of global climate change, frequent fluctuations and a significant increase in average temperatures will pose challenges to protecting those yields. Therefore, elucidating the molecular mechanisms that make crop plants more tolerant of heat, particularly in organs at the reproductive stage, is of utmost importance. Precise molecular information will be helpful for the manipulation and exploration of relevant genes for use in crop improvement programs. In this review, we highlight recent progress in research on the molecular responses to high temperatures in pollen and seed and provide a perspective on the development of heat tolerance in rice cultivars. The responsible mechanism is a very complex phenomenon that involves several biochemical and physiological changes, molecular responses, and a series of signal transductions. Improving our understanding requires detailed knowledge at various omics levels. Recent technological advancements have accelerated genomics, transcriptomics, and proteomics studies in rice, a model crop plant. Here, we discuss those technological and omics approaches being taken to investigate the heat tolerance mechanism, particularly in rice. In addition, we address the tools being used to identify key genes and QTLs that can then be utilized for molecular breeding and biotechnology.

“…In this study, after the first cultivar heading, the maximum temperature in HT was higher than that in CT by about 1. [9,15,16] showed that the pattern of flowering could vary among different genotypes. In general, rice anthesis begins at around 0900, peaks around 1000 to 1100, and ends around 1500.…”

“…The high temperature treatment was applied after the first cultivar showed the onset of anthesis. A temperature of 36 • C was chosen as the upper bound based on the well-documented physiological effects of high temperature on sterility and grain yield when the temperature exceeded 35 • C [6,15], and on the fact that this temperature was higher than the temperature in the field where these cultivars were cultivated.…”

High temperatures significantly affect rice grain yield and quality. However, little information is known about the response of indica cultivars, especially Vietnamese cultivars, to high temperature. In this study, field experiments were conducted in 2015 and 2016 to evaluate the response of Vietnamese cultivars under high temperatures during the grain filling period. The high temperature was applied after the first cultivar started anthesis, by opening two sides of a plastic chamber that housed the cultivar when the temperature reached above 36 • C under field conditions. The difference in the maximum temperature between the control and the high temperature treatment was about 1.3 • C to 10.1 • C in 2015, and 0.73 • C to 10.2 • C in 2016. Decreases in crop growth rate (CGR) and yield were correlated with increased temperature conditions during the grain filling period. The grain yield of 14 Vietnamese cultivars fell to 81.5 and 79.4% of the control in 2015 and 2016, respectively. The variable with the greatest impact on grain yield was spikelet sterility induced by high temperature. Under high temperature conditions during the grain filling period, the percentage of grain chalkiness in the high temperature-treatment group increased compared to the control. Our study showed that Vietnamese rice yield and quality were significantly affected by high temperature.
