• Abstract ( 730 ) HTML ( 534 ) PDF (1492KB) ( 534 ) 　　　
• The SELF-PRUNING（SP）gene belongs to a class of genes that regulate plant growth habits and flowering，it has been found in tomato to regulate the determinate of growth habits. Furthermore，it is homologous to the CENRORADIALIS（CEN）gene in Antirrhinum majus L. and the TERMINAL FLOWER 1（TFL1）gene in Arabidopsis thaliana. At present，eight members of SP gene family（SP，SP9D，SP2I，SP3D，SP5G，SP6A，SIGI，and SPGB）have been reported. The studies have shown that the family genes should directly or indirectly regulate the growth habits and affect the shoot architecture of tomato plants. Therefore，in this paper，the research on the genetic structure features，genetic relationships，expression characteristics，and plant architecture regulation of the SP family in tomato is reviewed，in order to regulate for growth habits of tomato，obtaining compact strains，achieve homogenization and modern mechanized harvesting，and agronomic traits and provide effective technical support.

Here discussed the spreading path of pepper across the world and provide evidence supporting its spreading route in China. After introduced into China through Zhejiang Province，C. annuum L. was first brought to North China，then to Liaoning and Hunan，and from Hunan rapidly spread to Southwest China，Northwest China and the surrounding regions，forming the spicy area in the upper and middle reaches of Yangtze River，the mild spicy area in North China，Northeast China and Northwest China，and slightly spicy area in the coastal region of East and South China. C. frutescens L. and C. chinense Jacq. was first introduced into China through Taiwan，then from Taiwan to Hainan and Yunnan. The motivation underlying the pepper spread in China was discussed，and its spread and cultivation history in China during the past 400 years was reviewed. Described how pepper has evolved from an ornamental crop，to a condiment crop，and now a major vegetable crop，and discussed the industrial function，value and scale of pepper in China as well as its industry position，advantage and prospect.

• Abstract ( 403 ) HTML ( 382 ) PDF (775KB) ( 382 ) 　　　
• Chilli veinal mottle virus（ChiVMV）was discovered in 1979 in peninsular Malaysia，and was subsequently found to spread all over the world. In China，the occurrence of ChiVMV was first reported in Shaanxi in 2003. Since then，incidences of ChiVMV have been noted in many other main pepper producing areas，such as Sichuan，Hunan，and Guizhou. ChiVMV has become one of the main viruses seriously jeopardizing pepper production. In this pape，we have emphatically summarized the disease symptoms induced by ChiVMV，viral transmission and strain differentiation，viral genome structure and function，the identification of pepper resistance to ChiVMV，resistance inheritance，and localization of molecular markers associated with resistance，with an attempt to provide theoretical references for further studies on breeding resistant varieties.
