| Why is the rose thorny? Experts put forward a new hypothesis of "prickly water storage" function |
Why do rose flowers have thorns? Recently, the plant molecular genetics and adaptation research team of the Kunming Institute of Botany, Chinese Academy of Sciences has cooperated with the Southwest Wildlife Germplasm Bank of China and the Yunnan Academy of Agricultural Sciences to analyze methods and methods such as comparative genomics, molecular genetics and evolutionary biology.
Prickles refer to sharp protrusions formed on the epidermis or cortex of plants.
To better understand the genetic regulation mechanism of rose thorn development, the team constructed a high-quality reference genome at the diploid BT chromosome level.
To further explore this hypothesis, the team conducted a series of physiological tests on 41 genotypes of rose.
"Although more genetic evidence is needed, this hypothesis completes the research chain of the biological functions of thorns, that is, young thorns are mainly used for water storage, while mature thorns are mainly used for defense and water loss.
Hu Jinyong said that this study explored the genetic regulation mechanism of rose thorns, revealed that gene expression variation may be the basis of phenotypic differentiation of thorns, proposed the physiological function hypothesis in the early development of thorns, and constructed important genetic and genomic resources.
