To clone and characterize the encoding FMRFamid-like peptides genes from
Meloidogyne incognita,
total RNA was extracted from the J2 nematodes.One gene was obtained by RACE and named
Mi-flp-16
(GenBank：EU549831).The full length cDNA sequence of
Mi-flp-16
was 690 bp,with a 528 bp ORF and encoding a 176 amino acids protein.The protein has three FLPs,including two AQTFVRF and one GQTFVRF.Using in situ hybridization technique to detect the expression of
Mi-flp-16,
found that it was expressed in neurones associated with the circumpharyngeal nerve ring.

ZHANG De-shuang;ZHANG Feng-lan;YU Yang-jun;ZHAO Xiu-yun;YU Shuan-cang;XU Jia-bing
CGMCC № 2553 were cultivated via isolated microspore culture and embryoids of different stages were obtained.DH regeneration plants were obtained by subculture.After DH plants were set at low temperature treatment situation for 15-20 days,they would grow in greenhouse or they were directly grew in greenhouse with naturally lower temperature for 30-40 days.Results showed 172 DH plants in 2006，230 DH plants in 2007 were obtained，275 plants had been domesticated in 2008.Some DH regeneration plants could transform into leaf mutants.From 2006 to 2007,8 wrinkledness leaf mutants were gotten.The highest rate of getting mutants was 2.29 %.2 mutant plants had gotten seeds.The leaf mutants mainly showed wrinkledness in the surface of preceding leaves at early stage.Then the wrinkle leaves could transfer to normal ones and some also keep the wrinkledness later with their growth.Further studies showed some DH plants could generate two or more than two stems in which wrinkledness mutant and wild type often burgeoned at the same parent.The mutants had the same characteristics as wild types except for the leaf wrinkledness,therefore they were the better materials for studying the wrinkledness characteristic.The finding is useful in studying,locating and cloning the wrinkledness gene(s)linked to leaf mutants of Brassica allosextuple CGMCC № 2553 DH lines in the future.

In the period of Chinese cabbage-pak-choi two leaves,the
ef
mutant plants were sprayed by different concentration of GA
3
and PP
333
treatments,respectively.Based on investigation of plant height,plant width,number of leaves and the dates of plant heading,budding and flowering,G-POD and APX activities were tested.Results showed that there was very significant difference in plant height，G-POD and APX activity by the treatment with GA
3
and PP
333
,but no difference in plant width and number of leaves.After the treatment with GA
3
,G-POD activity firstly declined then increased.But the result was just opposite by the treatment of PP
333
.APX activity declined firstly and then increased by the treatment of GA
3
and PP
333
.Different treatments had significant affects on flowering date of
ef
mutants,GA
3
treatment could stimulate their blossoming,while PP
333
treatment could delay their blossoming.

LONG Liang-kun;LI Zhi-kun;YAO Qing;WANG Yan;ZHU Hong-hui*
In pot experiments,tomato seedlings were inoculated with arbuscular mycorrhizal fungi
Glomus versiforme
(AM-1)and
Glomus
spp.(AM-2).The effects to mycorrhizal root percentage which under different substrate conditions or at different inoculation time were analyzed,respectively.The results indicated that the highest percent of micorrhizal root could be obtained by substrate of vermiculite and soil mixture at the ratio of 1∶3 in volume.No significant difference of mycorrhizal root percent was observed between inoculating at seeding stage and at oneleaf stage,but a significant decrease of mycorrhizal root percentage was present when inoculating at twoleaf stage.In pot experiment under greenhouse conditions,tomato seedlings with higher percentage of mycorrhizal root could delay the occurrence of tomato bacterial wilt(
Ralstonia solanacearum
).but at the later stage,the state of illness would become aggravate.

Effects of Transplanting Time on Growth and Yield of Chinese Chive Cultivated in Plate with Organic Substrate in Greenhouse
XU Zhen-hang;LI Kun;HAN Dao-jie;WANG Ying-hua;YU Xian-chang*
A greenhouse experiment was conducted to study effects of transplanting time on growth and yield of Chinese chive cultivated in plate filled with organic substrate.The results indicated that properly advancing or putting off the transplanting time could increase plant height,stem diameter and yield of Chinese chive and that trangplanting time of November 24 was the best.With transplanting time deferred,number and length of new roots decreased but leaf width increased,leaf number changed little.There was a responding relation between transplanting time and Chinese chive variety,which may be related to dormancy characteristic of Chinese chive variety and the nutrition accumulated in rhizoma and roots.Rhizogenesis,growth and yield of‘Pingjiu No.2’were higher than those of‘791’,‘Zigenhong’,and‘Xindugenhong’.
