**1. Introduction**

Plants are decisive for nurturing life on Earth, but climate change threatens global food security, poverty decrease, and sustainable agriculture [1,2]. Climate change events, such as altered rainfall patterns, mega-fires, droughts, soil salinity, floods, extreme temperatures, and spreading pests and diseases, are becoming more frequent and severe. These events directly and indirectly influence sustainable agriculture, food security, and people's livelihoods (FAO, Climate Change; https://www.fao.org/climate-change/en/, accessed on 8 March 2023). According to current climate change predictions, extreme temperatures exert a significant risk to the sustainability of major crops globally. These extreme temperatures hinder plant growth and development, trigger damage, and eventually cause yield shortfalls, making it difficult to reach the "ZERO HUNGER (Sustainable Development Goal 2)" (FAO-UN, https://www.fao.org/sustainable-development-goals/goals/goal-2/en/, accessed on 8 March 2023).

Plants cannot avoid temperature stress by relocating as they are immobile [3,4]. Consequently, plants have developed diverse mechanisms to acclimatize to stressful environments by changing their developmental, physio-biochemical, and molecular activities [1,4–8]. To fast-track the development of stress-resilient crops for sustainable agriculture, discovering approaches to improve plant stress tolerance is a vital mission for plant biologists worldwide. Therefore, this Special Issue entitled "Developing Temperature-Resilient Plants: Responses and Mitigation Strategies" (https://www.mdpi.com/journal/agronomy/special\_ issues/temperature\_resilient, accessed on 8 March 2023) was designed at the right time to collect the recent scientific advances on different mitigation strategies as well as stress adaptation and tolerance mechanisms to support the rising population. Twenty papers are published in this Special Issue, including 15 research and 5 review articles authored by a diverse group of scientists worldwide. Based on the published articles, this editorial presented the scientific advances in two sections, i.e., (1) genetics and genomics interventions and (2) agronomic and physiological interventions in developing temperature-resilient plants for the sustainable future.
