| contents | Short-term marine heatwaves have a limited impact on the lignocellulose of Thalassia hemprichii seagrass plant. Huang, Yuying Liu, Songlin Luo, Hongxue Jiang, Zhijian Wu, Yunchao Zhang, Xia Yin, Tingting Huang, Xiaoping Lignin Hydrocharitaceae Hot Temperature Climate Change Biomass Short-term marine heatwaves, driven by global climate change, frequently occur in coastal areas and increasingly threaten seagrass meadows by raising temperatures, which impair their ecological functions. Lignocellulose, a key component of plant cell walls, is crucial for maintaining plant morphology and resilience. However, empirical evidence on the response of seagrass lignocellulose to short-term marine heatwaves is limited. This gap hampers understanding of seagrass cell wall adaptation and their roles in blue carbon storage, disturbance resistance, and biodegradation defense. To address this gap, a 10-day laboratory simulation was conducted, featuring a control group at 26 °C and an experimental group at 35 °C. The study examined the impact of temperature on the different organic matter types (lignocellulose and non-structural carbohydrates) and the growth rate changes of the tropical seagrass Thalassia hemprichii. We found that high temperatures converted starch stored in rhizome tissues into soluble sugars, which was associated with a significant decrease in leaf growth and belowground biomass. This suggests that the energy stored in the form of starch was mobilized to meet the plant's metabolic demands in response to heat stress, but at the cost of overall growth. While the lignocellulose exhibited slightly lower values at higher temperatures compared to the control treatment, the difference was not significant. This may be due to the response of lignocellulose lagging, or the high contents of non-structural carbohydrates in seagrass providing sufficient energy to buffer short-term marine heatwaves. These results indicated that the lignocellulose may be more resilient to short-term warming events. |
