摘要

黑霉属以其作为植物病原体的重要作用而闻名,具有丰富的物种多样性。目前的研究报告了在巴基斯坦不同地区(Fairy Meadows, Gilgit Baltistan; Khanspur, Khyber Pakhtunkhwa)发现的M. ferrinii和M. populnea为新记录的Melampsora喜马拉雅山黑锈菌(Melampsora喜马拉雅)sp. 11 .作为新种,有助于了解锈菌的多样性和分布。通过比较形态解剖调查,证实了它们在大鼠属中的位置。利用扫描电镜对孢子进行了详细的形态表征,揭示了孢子的表面纹饰等形态特征。此外,分子分析进行了物种划分和解决系统发育关系,属Melampsora。结合形态解剖和系统发育数据,在巴基斯坦发现了先前未被记录的Melampsora ferrinii和M. populnea,其中包括一个新的分类群——喜马拉雅Melampsora sp. 11。

New species and new records of genus Melampsora (Melampsoraceae) from Pakistan using electron microscopy and DNA barcoding techniques.

The genus Melampsora, known for its significant role as a plant pathogen, exhibits a rich species diversity. Current study reports Melampsora himalayensis sp. nov. as new species with M. ferrinii and M. populnea as new records from different regions (Fairy Meadows, Gilgit Baltistan; Khanspur, Khyber Pakhtunkhwa) of Pakistan, contributing to the knowledge of rust fungi diversity and distribution. Their placement within genus Melampsora was validated by comparative morpho-anatomical investigation. Detailed morphological characterization was employed using Scanning electron microscopy which provided features of spore morphology including their surface ornamentation. Additionally, molecular analysis was performed for species delimitation and to resolve phylogenetic relationships within genus Melampsora. Combined morpho-anatomical and phylogenetic data led to the discovery of previously unrecorded species, Melampsora ferrinii and M. populnea from Pakistan, including a novel taxon, Melampsora himalayensis sp. nov. This study provides information about taxonomy, host range and distribution of Melampsora in Pakistan.
