However, the buds stimulated by high temperatures always have some innate shortcomings-the tubers are light and floating, and the seedlings grown are also wilted and droopy. In contrast, tubers stored at low temperatures may sleep longer, but when they wake up, they are more energetic. This experiment is quite interesting. The temperature is like an adjustment knob. Turning left will prolong the sleep period and improve the quality, while turning right will result in faster germination but poorer quality. Unfortunately, there is no middle gear that can achieve the best of both worlds. 6 Advances in Omics and Biotechnology Approaches 6.1 Omics-based discoveries in tuber development 6.1.1 Insights from transcriptomics When it comes to how potatoes cope with drought, transcriptomics can be a great help. Drought resistant experts like Saturna and Alegria quickly activate water regulatory genes when water is scarce (Sprenger et al., 2016). Sequencing revealed that they are particularly capable of activating "drought resistance specialists" such as PIP and HSPs-PIP is responsible for managing the water in cells, while HSPs act like emergency responders to deal with various stress injuries. However, Milva, a delicate variety, is not good anymore. When encountering drought, all key genes are wilted. Interestingly, the PYL4 gene is particularly active in the ABA signaling pathway, making it a 'secret weapon' for drought resistance. By comparing these genetic data with field performance, we can understand why some varieties do not survive drought, while others wilt after two droughts. These findings not only explain the differences in drought resistance, but also point out a clear path for breeding experts-specifically targeting these drought resistant genes to improve varieties is definitely correct.
