Plant biology explores the intricate lives of the green world, from the microscopic machinery inside a leaf to how entire forests adapt to a changing climate. This field investigates everything from how roots drink water to the complex chemical signals plants use to communicate, offering vital insights into food security and environmental resilience.

On Gist.Science, we make these discoveries accessible by processing every new preprint in this category directly from bioRxiv. For each study, we provide both a plain-language overview for curious minds and a detailed technical summary for researchers, ensuring that the latest findings in plant science are clear and actionable. Below are the most recent papers in plant biology, freshly summarized for you to explore.

Automated Landmark-Based Root Inoculation in Arabidopsis Using Computer Vision and Robotics

This paper presents the first automated, landmark-based root inoculation system for *Arabidopsis thaliana* that integrates computer vision and robotics to achieve precise, high-throughput delivery of microorganisms to specific root locations, thereby overcoming the limitations of manual methods in plant-microbe interaction studies.

Genetic encoding of climate-responsive stomatal developmental plasticity in tomato

This study utilizes multiplexed CRISPR/Cas9 editing of *SlSPCH* cis-regulatory sequences in tomato to identify genetic variants that modulate stomatal development in response to environmental cues, while simultaneously developing live-cell tracking reporters to elucidate the underlying cellular mechanisms of climate-responsive plasticity.

The Role of Phosphoenolpyruvate Carboxylase-Protein Kinase in C4 Photosynthesis: Insights from Zea mays Mutant Analysis

Although the phosphorylation of phosphoenolpyruvate carboxylase (PEPC) by PEPC-protein kinase in *Zea mays* alters the enzyme's sensitivity to malate inhibition in vitro, this post-translational modification is not essential for photosynthetic performance or field growth, indicating the presence of additional regulatory mechanisms in planta.

Transcription elongation factor SPT6L recruits ARGONAUTE to guide mRNA cytosine methylation preventing premature termination in plants

This study reveals that in plants, the transcription elongation factor SPT6L recruits AGO4 via its AGO-hook domain to guide sRNA-directed mRNA cytosine methylation, a process essential for preventing RNA polymerase II stalling and ensuring proper transcription termination.

Effects of agroforestry trees on microclimate and enset (Ensete ventricosum) morphophysiology in South Ethiopia

This study demonstrates that integrating scattered trees into enset homegardens in South Ethiopia significantly improves microclimate conditions and enhances most enset morphophysiological traits under canopy shade, supporting the potential of agroforestry systems to bolster climate resilience for this staple crop.
