Cloning of ACC Oxidase cDNA and Its Inhibition of Ethylene Synthesis by Its Antisense RNA in Transgenic Populus deltoides
Li Mingliang, Han Yifan, Li Ling, Tian Yingchuan, Li Ning, Wang Shiji
1999, 12(3): 223-228.
Abstract:
A 0.9 kb fragment of ACC oxidase cDNA fragment prepared from total tomato RNA was amplified by polymerase chain reaction (PCR) and cloned into pGEM R T vector.The cloned ACC oxidase gene was further inserted into a binary vector,pBin438,in an inverted orientation between the CaMV 35S promoter and Nos 3’termination sequence (pBACO).Transgenic poplar plants were obtained by regeneration of agrobacteriummediated transformed leaves.PCR and Southern blot analyses confirmed the integration of a single antisense ACC oxidase gene in transformed poplar genome.The results from RTPCR of RNAs isolated from transgenic poplar leaves confirmed that the antisense RNA of ACC oxidase presented in these transgenic plants.The amount of ethylene released from transgenic poplars was reduced significantly to about 28% of that released from nontransformed controls.

Zhou Zhichun, Huang Guanglin, Jin Guoqing
1999, 12(3): 229-236.
Abstract:
The set of 9yearoldheight data of 24 provenances of masson pine (Pinus massoniana Lamb,) from 9 regional trial locations with good growth was used to establish height response function for each provenance grown at different latitudes.It was observed that three response function parameters including mode latitude,homeostatic parameter and scale parameter were strongly related to provenance latitude.For the northern seed sources, mode latitudes were more than 3o~6o below latitudes of origin,whereas the southern seed sources attained best growth at latitudes near their origin.In general,larger estimate for a homeostatic parameter and scale parameter was obtained for the southern seed source,compared with the northern seed source.The sounthern provenances were less sensitive to environmental changes if planted over good sites.Considered the vigours in height growth of various provenances extended in different latitudes and the safe factors in seed transfer,the range of suitable planting site was determined for several famous superior provenances of masson pine.

Li Kun, Zeng Juemin
1999, 12(3): 244-250.
Abstract:
Transpiration of some tree species planted in hot and arid valley of Jinsha River has been studied on the spot since 1993.The result shows that those species planted successfully in the area tend to water deficit during drought period,and they can be divided into two groups according to their transpiration.The transpiration intensity of Acacia is lower than that of local species and Eucalyptus and that is characteristic of Acacia through the drought.Leaf temperature is effected remarkably by transpiration intensity and species with transpiration intensity lowing in drought period tent to wither and lose more their leaves.In addition,transpiration intensity of A.mangium and E.urophylla have both negative correlation with air temperature and positive correlation with air humidity that direct the transpiration of two species were restricted,and the other species have not remarkable correlation with those factors.
Study on Early Diagnosis for Pine Wilt Disease Causedby Bursaphelenchus xylophilusⅡ.The Effect of Pine Species, Dose and Nematode Origin on Oleores in Exudation Method
Yang Baojun, Liu Wei, Xu Fuyuan, Zhang Pei, Qu Huarong
1999, 12(3): 251-255.
Abstract:
In 1997~1998,different doses of PWN were used to inoculate Pinus thunbergii and P. massoniana,3 origins of PWN were used to inoculate P.massoniana, 7 pine species were inoculated with PWN,and the oleoresin exudation of pines were observed at regular intervals. The results show that when the inoculum dose in less,the abnormal oleoresin exudation of pines appears later and abnormal. oleoresin exudation of all the tested pines needs longer time the abnormal oleoresin exudation of pines inoculated with PWN from Nanjing appears faster and abnormal oleoresin exudation of all the tested pines needs shorter time;the unusual oleoresin yields of all the tested pines for susceptible pine species manifest the fastest and almost all of the pines die,the unusual oleoresin yields of pines in middle susceptible display faster and part of pines die,the unusual oleoresin yields of resistant pines manifest the slowest and the abnormal oleoresin exudation class is low. In this test the abnormal oleoresin exudations of 98% pines inoculated with PWN occur. The results fully prove that oleoresin exudation method can be used as early diagnosis for pine wilt disease. Winter is the ideal season for felling infested pines.

Chen Yinglong, Gong Mingqin, Wang Fengzhen, Chen Yu
1999, 12(3): 262-267.
Abstract:
This paper reports the influence on nutrient uptake of Eucalyptus urophylla seedlings 5 months after inoculation with Glomus and Pisolithus isolates alone or in competition in a nursery. Though concentrations of some mineral elements in roots or tops varied according to different fungal treatments,there was a substantial increase of nutrient amount of all elements in noculated seedlings. Phosphorus content in inoculated seedlings were 2.67 to 2.88 times of the uninoculated ones. The total content of N,K and B in the inoculated seedlings was respectively 3.58~7.00,2.65~3.18 and 2.78~3.88 folds of those of the uninoculated ones. The results showed that inoculation with Pisolithus and/or Glomus isolates affected nutrient uptake and their distribution in parts of seedlings. The two fungal isolates also influenced the acid phosphatase activity in roots.

1999, 12(3): 268-274.
Abstract:
A series of tests for pulp-making in the moso bamboo stands were conducted systematically in Anji Couny of Zhejiang Province,Shaowu County of Fujian Province and Fengxin County of Jiangxi Province,and practice was put into by establishing 20 hm2 high-yield model stand of moso bamboo for pulp-making. The results show that the productivity of moso bamboo stands are decided by habitat and scientific management,and has sighificant difference due to different management,site quality or different original bamboo stands state. A bamboo forest which is in an undesirable state in poor site can be guided toward the establishment of an ideal of normal state with technical measures such as loosing soil, fertilization,reasonable cutting,adjusting stands structure and so on.This paper also put forward the management model of moso bamboo stands for pulp-making by suiting measures to local conditions and classifying management to improve the economic effect,i.e.it is desirable model to take A measure of intensive management in class I site for 30~40 t·hm-2 high yield culms per on-and off-year,A or B measure of intensive management in class Ⅱ site for about 25 t·hm-2 moderate yield culms and C measure in class Ⅲ site for about 18 t·hm-2 yield culms.

Lu Mengzhu, Han Yifan, Du Shengming
1999, 12(3): 325-331.
Abstract:
Genetic engineering,a powerful tool to introduce economic traits into organisms,has wide application for the improvement of trees. Genetically improved trees will soon be commercialized after completing their field trials. The potential negative effects of the release of the transgenic trees to the environments must be evaluated on the scientific basis. The current regulations of genetically modified plants both in China and abroad were formulated on the scientific knowledge of the gene transferred and the plant as a receptor. It should be addressed that the criteria of the safety concern on the transgenic trees must be based on their biology in a manner of case by case,with the focus on the restriction of the gene contamination to the nature forestry. The general rules of the risk assessment and safety management of the genetic engineered trees in China are suggested in this review.
