Flavonoid Synthesis Pathway Response to Low-Temperature Stress in a Desert Medicinal Plant, (Sandrice).

(L.) Moq. (), also known as sandrice, is an important medicinal plant widely distributed in dunes across all the deserts of China.

Phylogeographic analysis reveals multiple origins of the desert shrub in northern Xinjiang, involving homoploid and tetraploid hybrids.

Hybrid speciation plays an important role in species diversification. The establishment of reproductive isolation is crucial for hybrid speciation, and the identification of diverse types of hybrids, particularly homoploid hybrid species, contributes to a comprehensive understanding of this process. is a constructive shrub widespread in arid Central Asia.

A novel TF molecular switch-mechanism found in two contrasting ecotypes of a psammophyte, Agriophyllum squarrosum, in regulating transcriptional drought memory.

Background: Prior drought stress may change plants response patterns and subsequently increase their tolerance to the same condition, which can be referred to as "drought memory" and proved essential for plants well-being. However, the mechanism of transcriptional drought memory in psammophytes remains unclear. Agriophyllum squarrosum, a pioneer species on mobile dunes, is widely spread in Northern China's vast desert areas with outstanding ability of water use efficiency.
