主　　题：invasion plant Mikania micrantha photosynthesis stomata stem 

摘      要：Mikania micrantha is a fast-growing global invasive weed species that causes severe damage to natural ecosystems and very large economic losses of forest and crop *** has advantages in photosynthesis,including a similar net photosynthetic rate as C4 plants and a higher carbon fixation *** used a combination of genomics and transcriptomics approaches to study the evolutionary mechanisms and circadian expression patterns of *** ***,16 positive selection genes focused on photoreaction and utilization of *** different tissues,98.1%of the genes associated with photoresponse had high expression in stems,and more than half of the genes of the C4 cycle had higher expression in stems than in *** stomatal opening and closing,2 genes of carbonic anhydrase(CAs)had higher expression at 18:00 than at 8:00,and the slow anion channel 1(SLAC1)and high-leaf-temperature 1 kinase(HT1)genes were expressed at low levels at 18:*** addition,genes associated with photosynthesis had higher expression levels at 7:00 and 17:*** hypothesized that *** may undergo photosynthesis in the stem and flower organs and that some stomata of the leaves were opening at night by CO_(2)*** addition,its evolution may attenuate photoinhibition at high light intensities,and enhance more efficient of photosynthesis during low light *** the tissue-specific photosynthetic types and different diurnal pattern of photosynthetic-related genes may contribute to its rapid colonization of new habitats of ***.
