Abstract

The ARABIDOPSIS LIGHT-DEPENDENT SHORT HYPOCOTYLS 1 and rice G1/LIGHT-DEPENDENT SHORT HYPOCOTYLS (ALOG/LSH) group proteins are highly conserved across plant lineages from moss to higher flowering plants, suggesting their crucial role in the evolution and adaptation of land plants. The role of ALOG/LSH proteins is highly conserved in various developmental responses, such as vegetative and reproductive developmental programs. Their role in meristem identity, cotyledon development, seedling photomorphogenesis, and leaf and shoot development has been relatively well established. Moreover, several key pieces of evidence suggest their role in inflorescence architecture and flower development, including male and female reproductive organs and flower colouration. Recent research has started to explore their role in stress response. Functionally, ALOG/LSH proteins have been demonstrated to act as transcriptional regulators and are considered a newly emerging class of transcription factors in plants that regulate diverse developmental and physiological processes. This review aims to stimulate discussion about their role in plant development and as transcription factors. It also seeks to further unravel the underlying molecular mechanism by which they regulate growth and development throughout the plant lineage.

ALOG/LSHs 是一类新型转录因子：植物生长和发育的进化保守调节因子。

从苔藓植物到高等有花植物，ALOG/LSH 蛋白组在植物谱系中高度保守，这表明它们在陆生植物的进化和适应过程中起着至关重要的作用。ALOG 蛋白在各种发育反应（如无性和生殖发育程序）中的作用高度保守。它们在分生组织特征、子叶发育、幼苗光形态发生以及叶片和嫩枝发育中的作用已得到相对公认。此外，一些关键证据表明，它们在花序结构和花的发育（包括雌雄生殖器官和花的着色）中发挥作用。最近的研究开始探索它们在胁迫响应中的作用。在功能上，ALOG 蛋白已被证明可作为转录调节因子发挥作用，被认为是植物中新出现的一类转录因子，可调节多种发育和生理过程。本综述旨在激发对其在植物发育中的作用及其作为转录因子的作用的讨论。本综述还旨在进一步揭示它们调控整个植物品系生长和发育的潜在分子机制。

期刊介绍： The Journal of Experimental Botany publishes high-quality primary research and review papers in the plant sciences. These papers cover a range of disciplines from molecular and cellular physiology and biochemistry through whole plant physiology to community physiology. Full-length primary papers should contribute to our understanding of how plants develop and function, and should provide new insights into biological processes. The journal will not publish purely descriptive papers or papers that report a well-known process in a species in which the process has not been identified previously. Articles should be concise and generally limited to 10 printed pages.
