Poor seedling emergence is a challenge for direct seeding of rice under deep-sowing field *** we reveal that UDP-glucosyltransferase OsUGT75A promotes rice seedling emergence under deepsowing conditions by increasing shoot *** of OsUGT75A was higher in the middle regions of the shoot and in shoots under deep-sowing *** of free abscisic acid(ABA)and jasmonates(JA)were higher in shoots of OsUGT75A mutants than in those of wild-type plants,and OsUGT75A mutants were more sensitive to ABA and JA *** shoot length was attributed to higher ABA INSENSITIVE 3(OsABI3)expression and lower JASMONATE-ZIM domain protein(OsJAZ)expression in *** extension by OsUGT75A is achieved mainly by promotion of cell *** elite haplotype of OsUGT75A associated with increased shoot length was identified among indica rice ***75A acts to increase seedling emergence under deep-sowing conditions.

[Objective] This study was to investigate the allelopathic effects of *** leaf leachates on seedling growth and antioxidative enzymes,and thus to reveal physiologically allelopathic effects of *** trees on undergrowth plants.[Method] The allelopathic effects of leaf leachates of Jatropha curcas amended into soil were determined on the growth,proline and malondialdehyde（MDA） contentas well as superoxide dismutase（SOD）,catalase（CAT）,ascorbate peroxidase（APX）,guaiacol peroxidase（POD） in roots of marigold（Tagetes erecta） seedlings.[Results] The application of leaf leachates of *** in the soil significantly inhibited the shoot and root length of marigold compared to un-amended *** leaf leachates increased the O-2,H2O2,MDA and proline content in the roots of marigold *** effects increased with the ascending of leaf leachates *** addition,superoxide dismutase（SOD） and guaiacol peroxidase（POD） were not remarkably affected by the leachates at lower concentrations,but at higher concentration,SOD activity was ***,the activities of CAT and APX were also significantly increased with the increase of leachates concentrations.[Conclusion] These results show that *** can release the phytotoxic compound（s） into soil,which are inhibitory to certain test species by interfering with physiological process.
