Drought is the single greatest abiotic factor influencing crop yield worldwide. Plants remain in one area for extended periods, making them vulnerable to natural and man-made influences. Understanding plant drought responses will help us develop strategies for breeding drought-resistant crops. Large proteome analysis revealed that leaf and root tissue proteins respond to drought differently depending on the plant's genotype. Commonly known as tomatoes, Solanum Lycopersicum is a globally important vegetable crop. However, drought stress is one of the most significant obstacles to tomato production, making the development of cultivars adapted to dry conditions an essential goal of agricultural biotechnology. Breeders have put quite a lot of time and effort into the tomato to increase its productivity, adaptability, and resistance to biotic and abiotic challenges. However, conventional tomato breeding has only improved drought resistance due to the complexity of drought traits. The resilience of tomatoes under drought stress has been the subject of extensive study. Using contemporary sequencing approaches like genomics, transcriptomics, proteomics, and metabolomics has dramatically aided in discovering drought-responsive genes. One of the most prominent families of plant transcription factors, WRKY genes, plays a crucial role in plant growth and development in response to natural and abiotic stimuli. To develop plants that can withstand both biotic and abiotic stress, understanding the relationships between WRKY-proteins (transcription factors) and other proteins and ligands in plant cells is essential. This is despite the fact that tomatoes have a long history of domestication. This research aims to utilize Lupenone, a hormone produced in plant roots in response to stress, to increase drought resistance in plants. Lupenone exhibits a strong affinity for the WRKY protein at -9.64 kcal/mol. Molecular docking and modeling studies show that these polyphenols have a significant role in making Solanum Lycopersicum drought-resistant and improving the quality of its fruit. As a result of climate change, droughts are occurring more frequently and persisting for more extended periods, making it necessary to breed crops resistant to drought. While considerable variability for tolerance exists in wild cousins, little is known about the processes and essential genes influencing drought tolerance in cultivated tomato species.
干旱是全球范围内影响作物产量的最大非生物因素。植物在一个区域内停留很长时间,使它们容易受到自然和人为因素的影响。了解植物的干旱响应将有助于我们开发培育抗旱作物的策略。大规模的蛋白质组分析表明,叶片和根组织蛋白根据植物的基因型对干旱的反应不同。通常被称为番茄的 Solanum Lycopersicum 是一种全球重要的蔬菜作物。然而,干旱胁迫是番茄生产的最大障碍之一,因此培育适应干旱条件的品种是农业生物技术的重要目标。培育者在番茄上投入了大量的时间和精力,以提高其生产力、适应性以及对生物和非生物挑战的抗性。然而,由于干旱性状的复杂性,常规的番茄育种仅提高了其抗旱性。番茄在干旱胁迫下的恢复力一直是广泛研究的课题。利用基因组学、转录组学、蛋白质组学和代谢组学等现代测序方法,极大地帮助发现了对干旱有响应的基因。WRKY 基因是植物转录因子家族中最为突出的家族之一,在植物对生物和非生物刺激的生长和发育中起着至关重要的作用。为了培育能够耐受生物和非生物胁迫的植物,了解 WRKY-蛋白(转录因子)与植物细胞中其他蛋白质和配体之间的关系是至关重要的。尽管番茄有着悠久的驯化历史。本研究旨在利用植物根部在受到胁迫时产生的 Lupenone 来提高植物的抗旱性。Lupenone 与 WRKY 蛋白的亲和力为-9.64 kcal/mol。分子对接和建模研究表明,这些多酚类化合物在使 Solanum Lycopersicum 耐旱和提高其果实品质方面发挥着重要作用。由于气候变化,干旱发生的频率更高,持续时间更长,因此需要培育抗旱作物。虽然野生近缘种中有相当大的耐性变异,但对影响栽培番茄抗旱性的过程和关键基因知之甚少。
