摘要

在他们的2025 Science Advances研究中，Li等人发现ZmbZIP89是一种皮层和表皮特异性转录因子，是玉米侧根伸长和抗旱性的关键调节因子。通过综合关联和单细胞转录组学分析发现，其3'UTR的自然变异通过稳定mRNA、促进zmprx47介导的ROS稳态和适应性根性状来增强表达。这些见解揭示了对气候适应型作物进行根系性状改造的有希望的目标。

Rooting for survival: bZIP89 tunes cell-specific root plasticity and drought adaptation in maize

In their 2025 Science Advances study, Li et al. identified ZmbZIP89, a cortex- and epidermis-specific transcription factor, as a key regulator of lateral root elongation and drought resilience in maize. Natural variation in its 3′UTR enhances expression by stabilizing mRNA, promoting ZmPRX47-mediated ROS homeostasis and adaptive root traits, as revealed through integrated association and single-cell transcriptomic analyses. These insights reveal promising targets for engineering root traits toward climate-resilient crop development.

期刊介绍： Plant Science will publish in the minimum of time, research manuscripts as well as commissioned reviews and commentaries recommended by its referees in all areas of experimental plant biology with emphasis in the broad areas of genomics, proteomics, biochemistry (including enzymology), physiology, cell biology, development, genetics, functional plant breeding, systems biology and the interaction of plants with the environment. Manuscripts for full consideration should be written concisely and essentially as a final report. The main criterion for publication is that the manuscript must contain original and significant insights that lead to a better understanding of fundamental plant biology. Papers centering on plant cell culture should be of interest to a wide audience and methods employed result in a substantial improvement over existing established techniques and approaches. Methods papers are welcome only when the technique(s) described is novel or provides a major advancement of established protocols.
