| 1 | Shortened Basal Internodes Encodes a Gibberellin 2-Oxidase and Contributes to Lodging Resistance in Rice显示文摘改进住宿抵抗的繁殖半矮子变化被证明了在自从绿 revolution.?However 的来临,增加谷物产量极其成功,在亚洲繁殖半矮子米饭变化的多数主要依赖于 SD1 的变异的等位基因的基因介绍,它编码赤霉素( GA ) 20-oxidase , OsGA20ox2 ,为催化 GA 生合成。这里,我们报导新米饭住宿抵抗基因,弄短的基础 Internodes (SBI ) ,它编码赤霉素 ? 2-oxidase 并且明确地控制灰煤杆的延伸通过撤销的基础 internodes GA 活动。SBI 主要在灰煤杆被表示基础 internodes。基因分析显示 SBI 是影响米饭高度和住宿抵抗的半主导的基因。SBI 突变而产生之遗传的变体显示不同活动并且与米饭变化的高度被联系。与 SBI 等位基因的更高的活动繁殖与改进住宿抵抗和增加的产量产生新米饭变化。SBI 的发现为生产半矮子米饭显型提供一个理想的基因资源并且为与提高的住宿抵抗和高产量引起米饭变化提供有效策略。 | Chang Liu Jinshan Gui Chenjian Fu Hasi Yu Dongliang Song Junhui Shen Peng Qin Xuanming Liu Bin Han Yuanzhu Yang Laigeng Li | 2018 | Molecular Plant2018，11，2： | 33 |
| 2 | Phosphorylation of LTF1, an MYB Transcription Factor in Populus, Acts as a Sensory Switch Regulating Lignin Biosynthesis in Wood Cells显示文摘Lignin is specifically deposited in plant secondary cell walls,and initiation of lignin biosynthesis is regulated by a variety of developmental and environmental signals.However,the mechanisms governing the regulation of lignin biosynthesis remain to be elucidated.In this study,we identified a lignin biosynthesis-associated transcription factor(LTF)from Populus,LTF1,which binds the promoter of a key lignin biosynthetic gene encoding 4-coumarate-CoA ligase(4CL).We showed that LTF1 in its unphosphorylated state functions as a regulator restraining lignin biosynthesis.When LTF1 becomes phosphorylated by PdMPK6 in response to external stimuli such as wounding,it undergoes degradation through a proteasome pathway,resulting in activation of lignification.Expression of a phosphorylation-null mutant version of LTF1 led to stable protein accumulation and persistent attenuation of lignification in wood cells.Taken together,our study reveals a mechanism whereby LTF1 phosphorylation acts as a sensory switch to regulate lignin biosynthesis in response to environmental stimuli.The discovery of novel modulators and mechanisms modifying lignin biosynthesis has important implications for improving the utilization of cell-wall biomass. | Jinshan Gui Laifu Luo Yu Zhong Jiayan Sun Toshiaki Umezawa Laigeng Li | 2019 | Molecular Plant2019，12，10： | 10 |
| 3 | Phenylpropanoid Derivatives Are Essential Components of Sporopollenin in Vascular Plants显示文摘The outer wall of pollen and spores,namely the exine,is composed of sporopollenin,which is highly resistant to chemical reagents and enzymes.In this study,we demonstrated that phenylpropanoid pathway derivatives are essential components of sporopollenin in seed plants.Spectral analyses showed that the autofluorescence of Lilium and Arabidopsis sporopollenin is similar to that of lignin.Thioacidolysis and NMR analyses of pollen from Lilium and Cryptomeria further revealed that the sporopollenin of seed plants contains phenylpropanoid derivatives,including p-hydroxybenzoate(p-BA),p-coumarate(p-CA),ferulate(FA),and lignin guaiacyl(G)units.The phenylpropanoid pathway is expressed in the tapetum in Arabidopsis,consistent with the fact that the sporopollenin precursor originates from the tapetum.Further germination and comet assays showed that this pathway plays an important role in protection of pollen against UV radiation.In the pteridophyte plant species Ophioglossum vulgatum and Lycopodium clavata,phenylpropanoid derivatives including p-BA and p-CA were also detected,but G units were not.Taken together,our results indicate that phenylpropanoid derivatives are essential for sporopollenin synthesis in vascular plants.In addition,sporopollenin autofluorescence spectra of bryophytes,such as Physcomitrella and Haplocladium,exhibit distinct characteristics compared with those of vascular plants,indicating the diversity of sporopollenin among land plants. | Jinp-Shi Xue Baocai Zhang HuaDong Zhan Yong-Lin Lv Xin-Lei Jia TianHua Wang Nai-Ying Yang Yu-Xia Lou Zai-Bao Zhang Wen-Jing Hu Jinshan Gui Jianguo Cao Ping Xu Yihua Zhou Jin-Feng Hu Laigeng Li Zhong-Nan Yang | 2020 | Molecular Plant2020，13，11： | 2 |
