Summary: Piao et al. (2022) presents a study that examines vegetation phenology from a novel angle, focusing on the speed of canopy development and senescence. The study explores the relationship between the acceleration of vegetation phenological changes and the trend of vegetation greening/browning, as well as the underlying climate driving factors. This research is a significant contribution to our understanding of how vegetation responds to climate change and may inspire new directions in vegetation phenology research.

Summary: Climate change is directly altering the bioclimatic conditions during the growing period of trees, as well as indirectly affecting the timing and length of the season through shifts in leaf phenology. Research shows that climate change has led to advanced leaf unfolding and delayed leaf colouring, impacting the growing period and precipitation levels for different tree species in Central Europe. The findings suggest an increased drought stress, particularly at lower elevations, with future forest productivity depending significantly on elevation and species composition.

Summary: This study utilized a historical seed collection of Brassica rapa to investigate the evolutionary changes in disease susceptibility to a necrotrophic fungal pathogen following a drought. The results showed that the well-characterized necrotrophic fungal pathogen response genes have evolved between ancestors and descendants, with the jasmonic acid signaling pathway playing a crucial role in disease susceptibility evolution. Additionally, the study identified genes that respond to drought and evolved between ancestors and descendants, indicating drought as the evolutionary driver and genetic pleiotropy as a possible consequence of increased disease susceptibility.

Summary: This study identified and crossed different cotton genotypes for drought-tolerance, evaluated their performance under contrasting water regimes, and highlighted the importance of drought-tolerant varieties in cotton production. The results indicate that drought tolerance in cotton is under genetic control, with certain combinations showing potential for improving drought tolerance and early maturity.

Summary: Climate change can cause phenological mismatches between species, affecting their fitness and population dynamics. The study focuses on the winter moth, whose eggs hatch before their food source becomes available due to warmer winters. The mismatch leads to increased mortality rates and affects caterpillar growth. Long-term data analysis shows that population density is significantly influenced by phenological mismatch, with smaller mismatches resulting in higher population growth rates.

Summary: This study aims to investigate the impacts of climate variability on Chinese cabbage economic yields in South Korea and develop a yield prediction model using machine learning techniques. The results show that there are variations in economic yields and revenue for different Chinese cabbage groups under different climate change and cropping management plans. These findings provide farmers with a better understanding of the relationship between production and economic benefits in future climate change scenarios.

Summary: This study reveals the previously unknown functions of BrHSBP1 in Brassica rapa. BrHSBP1 was shown to be abundant in flower buds and young leaves, while its segmental duplicate, BrHSBP1-like, was abundant in green siliques. Different stress conditions and phytohormones were found to regulate BrHSBP1 differently. Overexpression of BrHSBP1 improved pod and seed sizes, while knockout mutants of BrHSBP1 were associated with aborted seed and pod development. BrHSBP1 was found to be involved in seed development by modulating the expression of RSD genes.

Summary: Research found that temperature-sensitive plant species experienced higher levels of insect damage in warm years, while co-occurring species that are less temperature-sensitive did not. With climate warming, warming may lengthen the growing season for temperature-sensitive plant species, exposing their leaves to herbivores for longer periods of time.

Summary: The use of leaf mesophyll protoplasts for plant transformation and genome editing has been limited due to the difficulty in regenerating protoplasts. This study investigated the reasons for protoplast recalcitrance and proposed a method to prevent catabolic reprogramming of protoplasts by blocking signaling pathways. The results provide insights into the molecular mechanisms of protoplast senescence and offer potential strategies for improving plant breeding techniques.

Summary: Droughts are a common natural disaster that severely impact human society. This study examined the evolution and characteristics of drought in China for historical and future periods. The results showed that drought areas and intensities would generally decrease slightly in the near future but increase substantially in the distant future. Population exposure to different levels of drought would also vary among scenarios. Therefore, both short- and long-term drought mitigation and adaptation measures are needed to address potential climate change in China.

Summary: Climate-driven changes in phenology are common and modeling these shifts is challenging. We propose a hierarchical modeling framework that can estimate intra-annual patterns and interannual rates of change in phenology, while accounting for observation error and variation in phenological processes. We demonstrate the application of this framework in two migratory species. By increasing precision and considering uncertainty and imperfect data sets, our approach helps ecologists understand how organisms respond to climate change.

Summary: This review summarizes recent literature on predictable seasonal and phenological patterns of acclimation and deacclimation to heat, cold, and water-deficit stress in perennial plants, with a focus on woody species native to temperate climates. The author highlights promising high-throughput techniques for quantifying stress tolerance traits and provides a synthetic framework of "phenological physiology" that can aid in climate change adaptation and mitigation.

Summary: This study investigated the effects of microwave ultrasonic-assisted extraction (MUAE) on the content, structure, and biological functions of Brassica rapa L. polysaccharide (BRP). A neutral polysaccharide named BRP-1-1 was isolated and purified, and its structure was elucidated. The results showed that BRP-1-1 had significant biological activities and could be developed as a functional medicine.
