TI  - Continuous Cropping Inhibits Photosynthesis of Polygonatum odoratum.
LID - 10.3390/plants12193374 [doi]
LID - 3374
AB  - Polygonatum odoratum (Mill.) Druce possesses widespread medicinal properties; 
      however, the continuous cropping (CC) often leads to a severe consecutive 
      monoculture problem (CMP), ultimately causing a decline in yield and quality. 
      Photosynthesis is the fundamental process for plant growth development. Improving 
      photosynthesis is one of the most promising approaches to increase plant yields. 
      To better understand how P. odoratum leaves undergo photosynthesis in response to 
      CC, this study analyzed the physiochemical indexes and RNA-seq. The 
      physiochemical indexes, such as the content of chlorophyll (chlorophyll a, b, and 
      total chlorophyll), light response curves (LRCs), and photosynthetic parameters 
      (F(v)/F(m), F(v)/F(0), F(m)/F(0), Pi(abs), ABS/RC, TRo/RC, ETo/RC, and DIo/RC) 
      were all changed in P. odoratum under the CC system. Furthermore, 13,798 genes 
      that exhibited differential expression genes (DEGs) were identified in the P. 
      odoratum leaves of CC and first cropping (FC) plants. Among them, 7932 unigenes 
      were upregulated, while 5860 unigenes were downregulated. Here, the DEGs encoding 
      proteins associated with photosynthesis and carbon assimilation showed a 
      significant decrease in expression under the CC system, such as the PSII protein 
      complex, PSI protein complex, Cytochorome b6/f complex, the photosynthetic 
      electron transport chain, light-harvesting chlorophyll protein complex, and 
      Calvin cycle, etc., -related gene. This study demonstrates that CC can suppress 
      photosynthesis and carbon mechanism in P. odoratum, pinpointing potential ways to 
      enhance photosynthetic efficiency in the CC of plants.
