The inhibition of N2 fixation by nitrogen is attenuated by the P supply, altering the plant metabolism Environ. Exp. Bot. (IF 5.7) Pub Date : 2024-03-31 Ricardo A. Cabeza, Joachim Schulze, Sebastian Salinas-Roco, Amanda Morales-González, Ramón Amigo, Ricardo Pérez-Díaz, Basilio Carrasco, Rodrigo Contreras-Soto, Carlos Maldonado, Romina Pedreschi, Soledad Espinoza, Alejandro del Pozo
Soil nitrogen (N) acts as an inhibitor to the biological process of N fixation in legumes. Conversely, the phosphorus (P) supply fosters N fixation by promoting nodule formation, facilitating energy transfer, activating enzymes, and enhancing nitrogenase activity. This could help counteract the inhibitory effects that high soil N levels can have on N fixation in legumes. However, there is limited knowledge

Soil salinity is a major environmental constraint affecting agricultural production systems. Boron (B) is an essential micronutrient for plants. This work was aimed to reveal the mechanistic basis of amelioration of detrimental effects of salinity on plant performance by boron. Barley () plants were exposed to different boron (HBO, from 0 to 1 mM) and salt (NaCl, 0 and 100 mM) treatments demonstrating

Epigenetic regulations under plant stress: A cereals perspective Environ. Exp. Bot. (IF 5.7) Pub Date : 2024-02-10 Vishal Dinkar, Saurabh Pandey, Amarjeet Kumar, Aalok Shiv, Dalpat Lal, Alka Bharati, Anjali Joshi, Sneha Adhikari, Aparna, Ashutosh Singh, Pramod Kumar Pandey, Ajay Kumar Chandra
In the era of global climate change, abiotic stresses are the most prominent factors limiting crop productivity worldwide. Besides the gradual increase in global mean temperature, altered weather patterns, frequency of heat spikes, and drought episodes are some of the major consequences of changing climate, which threatens global food security. This problem warrants immediate attention and could be

Genome-wide characterization of the constitutively stressed (COST) family genes and their response to salt stress in poplar Environ. Exp. Bot. (IF 5.7) Pub Date : 2024-02-10 Erkun Chao, Zhihui Zhu, Yanwen Wang, Rui Cheng, Shuang Cheng, Limin Wang, Yanqiu Zhao, Shuangxi Xiong, Min Chen, Nianwei Qiu, Hongxia Zhang
In Arabidopsis, () negatively regulates drought tolerance by interacting with the key autophagy adaptor. However, the biological functions of family genes in other plants remain unknown. In this study, a total number of 11 genes, distributed on 8 chromosomes, were identified in the poplar genome. Phylogenetic analysis indicated that they were classified into 4 groups, and have gone through 2 tandem
