“…The rapid response mechanism of plants to high light stress and light fluctuation is crucial for their adaptation to changing environments (Gjindali et al, 2021;Morales and Kaiser, 2020;Shi et al, 2022). Previous studies have indicated that the light saturation point of soybean is typically between 40 000 and 60 000 Lux (Wang et al, 2023;Yang and Miao, 1983) study, we discovered that the PLP protein can dynamically regulate soybean's resistance to high light stress by sensing varying intensities of blue light. On one hand, GmPLP1 can influence the efficiency of light energy utilization.…”

“…The rapid response mechanism of plants to high light stress and light fluctuation is crucial for their adaptation to changing environments (Gjindali et al ., 2021; Morales and Kaiser, 2020; Shi et al ., 2022). Previous studies have indicated that the light saturation point of soybean is typically between 40 000 and 60 000 Lux (Wang et al ., 2023; Yang and Miao, 1983). Stresses such as fluctuating light and high light can significantly decrease the light saturation point and photosynthetic capacity of leaves, especially when multiple stresses occur simultaneously, it will seriously damage the growth and yield of soybean.…”

“…In this study, we proposed a new working model for PLP1‐VTC2 protein pairs; that is, PLP1 limits the rate of GGP in terms of enzyme activity. Previous studies have found that the light saturation point of soybean is generally between 40 000 and 60 000 Lux (Wang et al ., 2023; Yang and Miao, 1983). When the plant leaves are exposed to high light at noon (10:00–15:00 h), the level of PLP1 protein decreases rapidly and weakens the interaction with VTC2, thus relieving the inhibition of GGP activity to ensure sufficient AsA synthesis to protect photosynthetic organs.…”

SummaryHigh light stress is an important factor limiting crop yield. Light receptors play an important role in the response to high light stress, but their mechanisms are still poorly understood. Here, we found that the abundance of GmPLP1, a positive blue light receptor protein, was significantly inhibited by high light stress and mainly responded to high blue light. GmPLP1 RNA‐interference soybean lines exhibited higher light energy utilization ability and less light damage and reactive oxygen species (ROS) accumulation in leaves under high light stress, while the phenotype of GmPLP1:GmPLP1‐Flag overexpression soybean showed the opposite characteristics. Then, we identified a protein–protein interaction between GmPLP1 and GmVTC2, and the intensity of this interaction was primarily affected by sensing the intensity of blue light. More importantly, overexpression of GmVTC2b improved soybean tolerance to high light stress by enhancing the ROS scavenging capability through increasing the biosynthesis of ascorbic acid. This regulation was significantly enhanced after interfering with a GmPLP1‐interference fragment in GmVTC2b‐ox soybean leaves, but was weakened when GmPLP1 was transiently overexpressed. These findings demonstrate that GmPLP1 regulates the photosynthetic capacity and ROS accumulation of soybean to adapt to changes in light intensity by sensing blue light. In summary, this study discovered a new mechanism through which GmPLP1 participates in high light stress in soybean, which has great significance for improving soybean yield and the adaptability of soybean to high light.

“…Several studies have reported the molecular mechanisms underlying FtsH regulation in plants. For example, a soybean study reported that GmFtsH25 interacts with photosystem I light-harvesting complex 2 (GmLHCa2), which contributes to enhanced photosynthesis [ 39 ]. An arabidopsis study found that AtFtsH11 is a critical regulator of photosynthetic thermotolerance.…”

Photosystem II repair in chloroplasts is a critical process involved in maintaining a plant’s photosynthetic activity under cold stress. FtsH (filamentation temperature-sensitive H) is an essential metalloprotease that is required for chloroplast photosystem II repair. However, the role of FtsH in tea plants and its regulatory mechanism under cold stress remains elusive. In this study, we cloned a FtsH homolog gene in tea plants, named CsFtsH5, and found that CsFtsH5 was located in the chloroplast and cytomembrane. RT-qPCR showed that the expression of CsFtsH5 was increased with leaf maturity and was significantly induced by light and cold stress. Transient knockdown CsFtsH5 expression in tea leaves using antisense oligonucleotides resulted in hypersensitivity to cold stress, along with higher relative electrolyte leakage and lower Fv/Fm values. To investigate the molecular mechanism underlying CsFtsH5 involvement in the cold stress, we focused on the calcineurin B-like-interacting protein kinase 11 (CsCIPK11), which had a tissue expression pattern similar to that of CsFtsH5 and was also upregulated by light and cold stress. Yeast two-hybrid and dual luciferase (Luc) complementation assays revealed that CsFtsH5 interacted with CsCIPK11. Furthermore, the Dual-Luc assay showed that CsCIPK11-CsFtsH5 interaction might enhance CsFtsH5 stability. Altogether, our study demonstrates that CsFtsH5 is associated with CsCIPK11 and plays a positive role in maintaining the photosynthetic activity of tea plants in response to low temperatures.

Plant structure has a large influence on crop yield formation, with branching and plant height being the important factors that make it up. We identified a gene, MtTCP18, encoding a TEOSINTE BRANCHED1/CYCLOIDEA/PROLIFERATING CELL FACTOR (TCP) transcription factor highly conserved with Arabidopsis gene BRC1 (BRANCHED1) in Medicago truncatula. Sequence analysis revealed that MtTCP18 included a conserved basic helix–loop–helix (BHLH) motif and R domain. Expression analysis showed that MtTCP18 was expressed in all organs examined, with relatively higher expression in pods and axillary buds. Subcellular localization analysis showed that MtTCP18 was localized in the nucleus and exhibited transcriptional activation activity. These results supported its role as a transcription factor. Meanwhile, we identified a homozygous mutant line (NF14875) with a mutation caused by Tnt1 insertion into MtTCP18. Mutant analysis showed that the mutation of MtTCP18 altered plant structure, with increased plant height and branch number. Moreover, we found that the expression of auxin early response genes was modulated in the mutant. Therefore, MtTCP18 may be a promising candidate gene for breeders to optimize plant structure for crop improvement.
