While research on terrestrial silicon (Si) biogeochemistry and its beneficial effects for plants has received significant attention in last decades, the reasons for the emergence of high-Si taxa remain unclear. Although the “arms race” hypothesis (i.e. increased silicification through co-evolution with mammalian grazers) has received some support, other studies have pointed to the role of environmental factors, such as high temperatures and low atmospheric CO2 levels, which could have favored the emergence of silicification. Here, we combine experimentation and analysis of existing databases to test the role of temperature on the expression and emergence of silicification in terrestrial plants. We first show through experimental manipulations of rice that Si is beneficial for growth under high temperature stress, but harmful under low temperature. We then found that, globally, the average temperature of the distribution of high-Si plants was 1.2°C higher than that of low-Si plants. Moreover, within China, a notable positive correlation emerged between the concentrations of phytoliths in wheat and rice and air temperature. From an evolutionary perspective, 65–77% of high-Si families (> 10 mg Si g− 1 DW) originated during warm geological periods, while 57–75% of low-Si families (< 1 mg Si g− 1 DW) originated during cold geological periods. On average, Earth's temperatures during the emergence of high-Si families were 3°C higher than those during the emergence of low-Si families. A correlation was also observed between the divergence of proteins related to Si transport (Lsi1, Lsi2, Lsi3, and Lsi6) and historical climatic variability. Together, cumulative evidence suggests that plant Si variation is closely related to global and long-term climate change, with potential repercussions for global Si and C biogeochemical cycles.

“…In summary, the accumulation of biomass before and after heading is crucial for rice yield improvement; however, to achieve super high yields, the focus should be on increasing the biomass yield during the post-heading stage. Moreover, high dry matter accumulation under a higher temperature than the critical range is associated with improved yield and stress tolerance ability in rice [39]. Generally, dry matter accumulation is the basis for high rice yields [20].…”

Super high-yielding rice (SHYR) (>15 t ha−1) plays a crucial role in global food production and security. We hypothesized that the external environment of different ecological regions could improve biomass accumulation in different periods and thus increase the rice yield. Two SHYR varieties, i.e., Xiangliangyou900 (XLY900) and Yliangyou900 (YLY900), were cultivated in the YONGSHENG and LONGHUI ecoregions, China. The results indicated that the average yield of the two SHYRs in the LONGHUI ecological region was 15.27–15.45 t ha−1 and 18.81–20.10 t ha−1 in YONGSHENG. The high grain yield in the YONGSHENG ecoregion was mainly due to the increased number of spikelets per panicle, crop growth rate, and total biomass during the transplanting–heading stage (TP-HS) and heading–maturity stage (HS-MS), and harvest index. The yield of SHYR was significantly correlated with external environment conditions, i.e., average minimum temperature, average daytime, and night-time temperature, and average daily temperature at the TP-HS, HS-MS, and transplanting–maturity (TP-MS) stages. The rice yield was significantly and positively correlated with the cumulative daily radiation. Therefore, it can be concluded that the final yield of super high-yield rice is closely related to the utilization of temperature and radiation resources during the growth process in the ecological environment.

Increased heat stress is a common feature of global climate change and can cause adverse impacts on crops from germination through maturation and harvest. This review focuses on the impacts of extreme heat (>35 °C) on plants and their physiology and how they affect food and water security. The emphasis is on what can be done to minimize the negative effects of heat stress, which includes the application of various materials and approaches. Nano-farming is highlighted as one promising approach. Heat is often combined with drought, salinity, and other stresses, which together affect the whole agroecosystem, including soil, plants, water, and farm animals, leading to serious implications for food and water resources. Indeed, there is no single remedy or approach that can overcome such grand issues. However, nano-farming can be part of an adaptation strategy. More studies are needed to verify the potential benefits of nanomaterials but also to investigate any negative side-effects, particularly under the intensive application of nanomaterials, and what problems this might create, including potential nanotoxicity.
