SWEET sugar transporters orchestrate distribution of microbiota along the root longitudinal axis

Plant roots are functionally distinct along the longitudinal axis due to different cell types and diverse metabolic states. Root-secreted metabolites are involved in the assembly of complex microbial communities, yet the relationships between root-metabolites and organization of root microbiota at the…

Unlocking nature’s arsenal: Engineering grasses for insect defense and livestock palatability

The defensive alkaloid gramine, present in barley and other grass species, plays an important role in protecting the plant from insect damage but poses challenges for ruminant palatability. Breeding strategies balance these factors by maintaining the protective function and making the grain palatable…

Hidden influence: How microbial stress responses shape plant natural selection

Soil microbial communities respond rapidly to stress, potentially leading to altered compositions in stressful environments and consequently impacting plant natural selection. Bolin and Lau investigated the influence of microbial responses to stress and persistent microbial legacy effects on plant selection.…

Unintended consequences of planting native and non- native trees in treeless ecosystems to mitigate climate change

Afforestation initiatives are globally underway to replace naturally treeless ecosystems with native and non-native trees. The primary objective is to enhance atmospheric carbon capture as a means to combat climate change. This review seeks to illuminate the diverse impacts of afforestation, both positive…

Plant Science Research Weekly: April 19, 2024

Review: Chloroplast ion homeostasis Healthy plants require access to several mineral nutrients, which are usually taken up in ionic form. The details of nutrient uptake, distribution, and function have been painstakingly revealed over several decades. In this excellent new Tansley Review, Kunz et…
