ZmILI1 confers salt stress tolerance by regulating genes of phytohormone response in maize Environ. Exp. Bot. (IF 5.7) Pub Date : 2024-01-28 Dandan Dou, Jianjun Sun, Salah Fatouh Abou-Elwafa, Xinhai Guo, Yuxi Guo, Dexin Wang, Chaoming Ding, Nahaa M. Alotaibi
Salt stress is a major abiotic stress that has severe adverse effects on the growth, development, yield and quality of crop plants. Molecular regulatory mechanisms underlying salt stress response in maize are still elusive. Understanding salt stress tolerance mechanisms is essential for the development of high-yielding maize cultivars with improved salt tolerance. Here, we identified a gene, INCREASED

Impact of micro and nano plastics on phototrophic organisms in freshwater and terrestrial ecosystems: A review of exposure, internalization, toxicity mechanisms, and eco-corona-dependent mitigation Environ. Exp. Bot. (IF 5.7) Pub Date : 2024-01-23 Sayani Giri, Christian O. Dimkpa, Disna Ratnasekera, Amitava Mukherjee
The large-scale manufacturing, extensive use, ineffective management, and improper disposal of plastics and plastic-containing products have made them one of the most significant environmental concerns of today. The transport of micro and nano plastics (MNPs) between terrestrial and freshwater environmental compartments, including reciprocal contributions and inherent connections, and the effects of

Mt14-3-3, interacting with MtNAC2, is involved in floral transition and multiple abiotic stress pathways Environ. Exp. Bot. (IF 5.7) Pub Date : 2024-01-23 Mengdi Wang, Yinruizhi Li, Yue Wang, Di Dong, Shuwen Li, Zhuocheng Liu, Liebao Han, Yuehui Chao
Evidence suggests that the 14-3-3 protein plays a role in a wide variety of physiological activities in plants. However, its specific role in Medicago truncatula remains unclear. For this study, a Mt14‐3‐3 gene was isolated from M. truncatula for further research. Subcellular localization data indicates that this gene is localized in both the cytoplasm and nucleus. Furthermore, the gene's response

Transcriptional patterns and histone modification signatures reveal dehydration memory behaviour in seedlings of Gossypium hirsutum Environ. Exp. Bot. (IF 5.7) Pub Date : 2024-01-19 Shibin He, Penghui Zhang, Yuehua Wang, Rui Zheng, Yaqian Li, Hui Cheng, Dong Lv, Yanfeng Sun, Chen Miao
In nature, plants often experience recurring stress conditions. Some plants have evolved a memory response, which shows an enhanced reaction upon subsequent stress. However, whether cotton ( L.) exhibits dehydration stress memory and the underlying mechanisms have remained unclear. Here, we characterized the responses to recurring dehydration stress in cotton seedlings from physiological changes, gene

Physical and molecular responses to flooding in Brassicaceae Environ. Exp. Bot. (IF 5.7) Pub Date : 2024-01-19 Rachel Combs-Giroir, Andrea R. Gschwend
Global flooding events are becoming more frequent due to climate change. Depending on the intensity, flooding can cause below-ground plant tissues to become waterlogged and above-ground plant tissues to become partially or fully submerged, leading to hypoxic environments. These conditions can damage plant tissue, leading to chlorosis and senescence, and typically halting plant growth and development
