The results of the study on the cold response and adaptation mechanism of sandalwood under low temperature (4 degrees C) treatment conditions were found.

There is a very close relationship between plants and the environment.
any plant, whether an individual or a group, needs to respond to the environment and respond positively anytime, anywhere, which is the only way to sustain its existence and development.
stress is one of the main abscesses that hinder plant growth, limit its geographical distribution and reduce crop yield.
sandalwood is one of the most expensive woody plants in the world and is known as "green gold".
, mainly cultivated in China, Sri Lanka, Indonesia, Malaysia, the Philippines and northern Australia and other Southeast Asian countries.
, sandalwood is mainly grown in tropical subtropical areas such as Guangdong, Hainan and Fujian.
temperature is one of the main environmental factors affecting the growth and distribution of sandalwood.
the current response and adaptation mechanism of sandalwood to hypothermia stress is still unclear.
Zhang Xinhua, Ph.D., South China Botanical Garden, Chinese Academy of Sciences, and other researchers carried out a comprehensive study on the cold response and adaptation mechanism of sandalwood under low temperature (4 degrees C) treatment conditions.
show that sandalwood has a positive cold response protection mechanism under low temperature stress.
shown in: accumulation of malondialehyde, proline and soluble sugars, significant increases in antioxidant enzyme SOD and POD levels; significant increases in transcriptions related to cell membrane transport, Ca ions, ROS, and plant hormone signals; and, more importantly, the increase in the level of 8 sandalwood terpenes in cold stress Enzyme genes have important differential expression in plant leaves and root tissue, and four key regulatory genes for cold domestication - CBFs transcription factors were identified, of which CBF2-CBF4 was expressed 50-200 times more than in the control group when cold stress was 12 h and 24 h, suggesting that cold signal transduction pathways dependent on CBF were likely to play a key role in cold tolerance in honolulu.
results provide an important theoretical basis for the study of sandalwood cultivation and breeding, as well as the biosynthetic mechanism of sandalwood oil.
