摘要

马铃薯的块茎化是一个复杂的发育过程，受光照和温度等环境因素以及遗传和生化因素的影响。块茎的形成与日照长度有关，较短的日照比较长的日照更有效地诱导块茎的形成。马铃薯块茎的产量受涉及激素、转录调节因子和糖类的信号网络调控。钙在这一过程中起着关键作用。钙传感器（包括钙调蛋白（CaMs）、钙调蛋白样蛋白（CMLs）、Ca2+依赖性蛋白激酶（CDPKs）和钙调蛋白-B样蛋白（CBLs））可检测到细胞质钙的升高，从而促进块茎的形成和生长。本综述从机理上深入探讨了马铃薯块茎化过程中的钙信号转导，强调了其在胁迫适应中的作用。本综述进一步探讨了钙/钙调蛋白在胁迫响应机制中的作用，以及促进适应干旱、寒冷、洪涝和热胁迫等环境挑战的膜转运体，这些环境挑战对全球马铃薯生产构成重大威胁。此外，钙信号有助于培养对非生物胁迫和病原体的耐受性，最终增强植物的免疫反应，保护马铃薯块茎。

Calmodulin and calcium signaling in potato tuberization: The role of membrane transporters in stress adaptation

Potato tuberization is a complex developmental process influenced by environmental factors, such as light and temperature, as well as genetic and biochemical factors. Tuber formation is responsive to day length, with shorter days inducing tuberization more effectively than longer days. Potato tuber yield is regulated by signaling networks involving hormones, transcriptional regulators, and sugars. Calcium plays a pivotal role in this process. Elevated cytoplasmic calcium is detected by calcium sensors, including calmodulins (CaMs), calmodulin-like proteins (CMLs), Ca²⁺-dependent protein kinases (CDPKs), and calcineurin-B-like proteins (CBLs), promoting tuberization and growth. This review provides mechanistic insights into calcium signaling in potato tuberization, emphasizing its role in stress adaptation. This review further explores the role of calcium/calmodulin in stress response mechanisms and the membrane transporters that facilitate adaptation to environmental challenges like drought, cold, flooding, and heat stress, which are significant threats to potato production globally. Additionally, calcium signaling helps develop tolerance to both abiotic stresses and pathogens, ultimately enhancing plant immune responses to protect potato tubers.

期刊介绍： Plant Physiology and Biochemistry publishes original theoretical, experimental and technical contributions in the various fields of plant physiology (biochemistry, physiology, structure, genetics, plant-microbe interactions, etc.) at diverse levels of integration (molecular, subcellular, cellular, organ, whole plant, environmental). Opinions expressed in the journal are the sole responsibility of the authors and publication does not imply the editors'' agreement. Manuscripts describing molecular-genetic and/or gene expression data that are not integrated with biochemical analysis and/or actual measurements of plant physiological processes are not suitable for PPB. Also "Omics" studies (transcriptomics, proteomics, metabolomics, etc.) reporting descriptive analysis without an element of functional validation assays, will not be considered. Similarly, applied agronomic or phytochemical studies that generate no new, fundamental insights in plant physiological and/or biochemical processes are not suitable for publication in PPB. Plant Physiology and Biochemistry publishes several types of articles: Reviews, Papers and Short Papers. Articles for Reviews are either invited by the editor or proposed by the authors for the editor''s prior agreement. Reviews should not exceed 40 typewritten pages and Short Papers no more than approximately 8 typewritten pages. The fundamental character of Plant Physiology and Biochemistry remains that of a journal for original results.
