竹亚科植物遗传多样性研究进展OA

[Background]The subfamily Bambusoideae is an important group within Poaceae,characterized by high species diversi-ty,wide geographic distribution and significant ecological,economic and cultural value.Since most bamboo species propagate mainly through clonal growth and have long flowering cycles,the assessment and conservation of genetic diversity in wild populations are particularly critical.[Progress]Research on the genetic diversity of Bambusoideae has progressed from the use of morphological,cy-tological and biochemical markers to the predominant application of molecular markers and high-throughput sequencing.These stud-ies have revealed the levels of genetic diversity and patterns of population differentiation in Arundinarieae and Bambuseae.They also indicate that the estimates of genetic diversity differ markedly among species and even for the same species across different studies.These discrepancies reflect the combined effects of geological history,biological characteristics,geographic distribution and human disturbance,as well as variation among molecular marker systems,making it difficult to summarize a universal pattern.[Prospect]Current studies are confronted with challenges such as incomplete taxonomic coverage,limited cross-validation among different con-clusions,and constraints on the applicability of conventional techniques.Future work should focus on strengthening studies of rare and endangered bamboo species,optimizing sampling strategies,standardizing technical protocols and promoting the application of high-throughput sequencing.These efforts will provide a reliable scientific basis for the conservation and sustainable utilization of bamboo resources.
