Summary: Long-distance signaling molecules, such as TCTP mRNA, are important in plant development and responses to the environment. TCTP regulates cell cycle progression, programmed cell death, and has various other functions. In this study, the role of TCTP in tuber development and vegetative propagation was investigated by analyzing its overexpression in a solanaceous plant model. The results showed that the overexpression of StTCTP led to larger sprouts and early tuber formation, indicating its involvement in vegetative propagation and asexual reproduction.

Summary: Calcium is essential for plants, and this study investigates the accumulation and deposition of calcium in tuber tissues, as well as its interaction with other essential nutrients. The results show that foliar sprayings of calcium chloride and calcium nitrate fertilizers can increase calcium accumulation in tubers, without significant impact on photosynthetic functions or tuber size. Furthermore, the accumulation patterns of other nutrients in tubers show distinct differences compared to calcium.

Summary: Potatoes are highly susceptible to elevated temperatures, which can lead to reduced photosynthetic capacity and membrane stability. Short and prolonged heat stress resulted in significant changes in gene expression and metabolite levels related to photosynthesis, heat response, and amino acid biosynthesis, suggesting their potential role in heat tolerance of potatoes. Additionally, heat-induced gene expression in Arabidopsis thaliana and potato leaves overlapped, and certain heat-induced genes in Nicotiana benthamiana increased heat tolerance. This study provides new insights into the molecular mechanisms underlying the potato's response to heat stress.

Summary: Excessive use of chemical fertilizers in semiarid areas leads to low yield and poor quality of potatoes. This study aimed to improve potato productivity by partially substituting organic fertilizers for chemical fertilizers. The results showed that the application of 80% chemical fertilization + 6000 kg/ha organic fertilization significantly enhanced agronomic traits, photosynthetic characteristics, yield, and tuber quality of potatoes. Therefore, this fertilizer application pattern can be recommended for semiarid regions.

Summary: This study identified six SRO genes in the potato genome and identified StSRO6 as a major effector gene and StSRO5 as a secondary effector gene. By studying their expression patterns and co-expression networks under heavy metal stress, as well as through gene transformation and in vitro experiments, the study confirmed the role of StSRO6 in conferring Cd tolerance. The findings provide a new perspective on understanding the mechanisms underlying Cd tolerance in plants and offer clues for the development of biological agents for preventing and controlling Cd migration and transformation.

Summary: In this study, 37 StSOS1 genes were identified and found to be unevenly distributed across 10 chromosomes in potato, with most of them located on the plasma membrane. These genes contain abundant cis-elements involved in various abiotic stress responses. Tissue specific expression showed that 21 of the 37 StSOS1 genes were widely expressed in various tissues or organs of the potato. Molecular interaction network analysis suggests that these genes may interact with other proteins involved in potassium ion transmembrane transport, response to salt stress, and cellular processes. Collinearity analysis showed orthologous StSOS1 genes in tomato, pepper, tobacco, and Arabidopsis. Moreover, the expression of StSOS1 genes were significantly modulated by various abiotic stresses, especially salt and abscisic acid stress. Subcellular localization in Nicotiana benthamiana suggested that StSOS1-13 was located on the plasma membrane. These results provide a comprehensive overview of the StSOS1 gene family and pave the way for further analysis of their function in SOS and hormone signaling pathways.

Summary: Freezing severely affects potato production. Understanding the pathways and metabolites that regulate potato's freezing tolerance is beneficial for cultivation and breeding purposes. In this study, it was found that Solanum acaule is more freezing tolerant compared to S. tuberosum. Through RNA-seq and metabolomics analysis, it was discovered that S. acaule activated different genes and enriched certain pathways, such as the hormone signaling pathway involving salicylic acid. Further analysis showed that the content of salicylic acid increased in S. acaule after exposure to cold conditions, leading to improved freezing tolerance. Additionally, the application of salicylic acid to potato enhanced freezing tolerance and increased the expression of HSFC1.

Summary: The study evaluated the efficiency of calcium enrichment in potato tubers through foliar spraying with different calcium solutions. Different potato varieties showed varying levels of calcium accumulation, with Rossi having a lower index potentially due to different metabolic characteristics. While the foliar spraying had some impact on quality parameters, the overall quality of potato tubers for industrial processing was maintained.

Summary: The ZxZF transcription factor plays an important role in improving the drought resistance and photosynthetic efficiency of transgenic poplar trees. It regulates stomatal opening, increases the concentration of CO2, and alleviates the inhibition of carbon assimilation under drought stress. It also maintains the orderly transport of photosynthetic electron transport chain and the integrity of the photosystem.

Summary: Shade avoidance syndrome (SAS) is an adaptive strategy that involves elongation of the stem and petiole, leaf hyponasty, and altered phototropic orientation in response to reduced blue light and low red:far-red ratio. BBX24 and JAZ3 are key regulators in the SAS pathway, jointly controlling DELLA activity and plant growth.

Summary: B-Box-containing zinc finger transcription factor BBX21 inhibits hypocotyl elongation in Arabidopsis through the brassinosteroid pathway. It reduces sensitivity to synthetic active brassinosteroid 24-epiBL at low concentrations in simulated shade and represses the biosynthesis and signaling genes of brassinosteroids. BBX21 integrates brassinosteroid homeostasis and shade-light signaling to fine-tune hypocotyl elongation in Arabidopsis.
