The ambient temperature for plant growth is increasingly unpredictable under the changing climate. To ensure growth, the leaf is the immediate organ responding to maintain photosynthesis. In this review, Yang et al. point out stomatal development and dynamics as the adaptive responses to long-term and short-term temperature stresses respectively. Prolonged exposure to heat reduces stomatal […]
Crops such as rice usually flower in the late morning when the ambient temperature rises. Rice plants briefly open their flowers so the mature anthers hang out. However, heat stress can trigger abnormal anther dehiscence, flower infertility, and subsequent yield reduction. Early-morning flowering has been proposed as a strategy to escape from heat and maintain […]
Plant roots exude organic compounds such as benzoxazinoids (BXs) to the surrounding soil. BXs modulate soil microbiota, which in turn regulate plant growth. In this study, Stengele et al. show that BX-modulated soil microbiota also promote plant immunity. The authors first pretreated soil with BXs by growing BX-secreting maize. They then used this BX-pretreated soil […]
Tea plants (Camellia sinenesis) are usually cultivated in warm and humid regions where fungal infections are favoured. Foliar diseases directly affect the quality of the leaves that are used for tea production. Colletotrichum camelliae is a common fungal pathogen infecting tea plants. Previous studies highlighted the importance of sulfate accumulation in defense against the fungus. […]
Rapeseed (Brassica napus) is an important crop providing vegetable oil. Yield is positively correlated with increased numbers of seeds, siliques, and branches. In a previous study, a rapeseed germplasm having normal branch and silique numbers was crossed with another germplasm having higher branch and silique numbers to identify the causal quantitative trait locus, NIL. In […]
Wheat is rich in gluten proteins which provide texture and structure to many foods such as breads. The abundance of low molecular weight glutenin subunits (LMW-GSs) and high molecular weight glutenin subunits (HMW-GSs) determines gluten strength and dough quality. Wheat cultivars commonly contain three to five types of HMW-GSs. In a previous study, an ethyl […]
Grapevine is an important crop in the food industry. Like other crops, cultivated grapevine benefits from wild relatives that can be used for genetic resource mining and cultivar improvement. Useful genetic resources include novel alleles and gene expression regulators for better growth and stress resilience. In this study, Duan et al. reveal the promotion of […]
In Chinese, there is an old poem suggesting that livestock bites promote crop yield in the succeeding year. In this new work, Hu et al. provide evidence to support the traditional wisdom and propose the mechanism behind it. Previous studies showed that herbivore bites on leaves induce the release of volatiles, which activate jasmonate-dependent signalling […]
Rice feeds nearly half of the world population. Rice grains are rich in starch but low in micronutrients and bioactive compounds such as flavonoids. By contrast, tea leaves are rich in antioxidants such as catechins but low in calories. Zhu and colleagues combine the advantages of rice and tea by producing “tea rice”. They transformed […]
