Genome-wide identification of PSKR genes in wheat and differential expression under abiotic stress conditions

mycolabadmin

Scientists identified 149 genes related to phytosulfokine receptors (PSKR) in wheat that help plants respond to environmental stresses like drought, salt, cold, and heat. These genes are spread across wheat’s chromosomes and contain regulatory elements that control their expression in response to various stresses and plant hormones. The study provides important genetic resources for developing wheat varieties that are more resistant to environmental stress, which is crucial for maintaining crop productivity in changing climate conditions.

Research landscape of experiments on global change effects on mycorrhizas

mycolabadmin

Scientists conducted a comprehensive survey of research on how mycorrhizal fungi (underground fungi that partner with plant roots) respond to global environmental changes like drought and pollution. They found that most research focuses on just one stressor at a time, with very few studies examining how multiple environmental changes together affect these important fungi. The research also showed significant geographic biases, with most studies concentrated in developed countries, leaving major knowledge gaps about mycorrhizal responses in understudied regions.

Warming and Reduced Rainfall Alter Fungal Necromass Decomposition Rates and Associated Microbial Community Composition and Functioning at a Temperate–Boreal Forest Ecotone

mycolabadmin

Scientists studied how climate change affects the breakdown of dead fungal material in forest soils. They found that warmer temperatures and less rainfall initially speed up decomposition in the first two weeks, but then slow it down later. The microbial communities eating the dead fungi also changed over time, with different bacteria and fungi becoming dominant depending on soil moisture and temperature conditions.
