🌱 How do grassland plants survive persistent drought?
👏Thrilled to congratulate our client at Inner Mongolia University on their recent publication in Plant Diversity! Their research on Stipa grandis delivers several major advances in grassland evolutionary genomics and stress adaptation.
⭐️Key Highlights:
• First chromosome-level genome for Stipeae tribe — 1.152 Gb, 22 chromosomes, LAI 27.01 , enabled by integrated DNBSEQ + PacBio HiFi + Hi-C solutions
• Discovery of lineage-specific whole-genome duplication (WGD) — Identified a Stipeae-specific whole-genome duplication (~21–25 Mya) distinct from the ancestral ρ-WGD, with reconstructed chromosomal evolution from 12 ancestral to 22 modern chromosomes
• Decoding multi-layered drought networks — Whole-transcriptome profiling revealed root-biased rapid response via miRNA suppression, plus novel regulatory modules: miRNA-95-3p–ARF, miRNA-7-3p–BRI1, and lncRNA-AGPase switch in starch-sucrose metabolism.
These findings elucidate how a keystone steppe species molecularly adapts to persistent aridification, offering candidate genes and non-coding RNA targets for the development of drought-resilient forage grasses and informing conservation strategies for Eurasian grassland ecosystems.🥳
