Grapevine VlbZIP30 improves drought resistance by directly activating VvNAC17 and promoting lignin biosynthesis through the regulation of three peroxidase genes.
Mingxing Tu,Xianhang Wang,Wuchen Yin,Ya Wang,Yajuan Li,Guofeng Zhang,Zhi Li,Junyang Song,Xiping Wang +8 more
TL;DR: Overexpression of VlbZIP30 improves drought tolerance, characterized by a reduction in the water loss rate, maintenance of an effective photosynthesis rate, and increased lignin content in leaves under drought conditions.
Journal ArticleDOI
MYB-mediated regulation of lignin biosynthesis in grasses
TL;DR: Findings implicate important roles for MYB transcription factors in coordinated regulation of grass lignin biosynthesis including γ-acylated and tricin-incorporated lign in biosynthesis.

Yu Guo,Yumei Hu,Huan Chen,Pengshuai Yan,Qingguo Du,Yafei Wang,Hongqiu Wang,Zhonghua Wang,Ding-ming Kang,Wen-Xue Li +9 more
TL;DR: Results indicated that modification of cell wall biosynthesis would contribute to lodging resistance of maize.

Double knockout of OsWRKY36 and OsWRKY102 boosts lignification with altering culm morphology of rice.
Takuji Miyamoto,Rie Takada,Yuki Tobimatsu,Shiro Suzuki,Masaomi Yamamura,Keishi Osakabe,Yuriko Osakabe,Masahiro Sakamoto,Toshiaki Umezawa +8 more
TL;DR: The results provide evidence that both OsWRKY36 andOsWRKY102 are associated with repression of rice lignification, and relative abundances of guaiacyl and p-coumarate units were slightly higher and lower, respectively, in the WRKY mutant lignins compared with those in the wild-type lign ins.
Journal ArticleDOI
A comprehensive review on the potential of microbial enzymes in multipollutant bioremediation: Mechanisms, challenges, and future prospects.
TL;DR: In this article , a review focused on the enzymatic elimination of harmful contaminants in the environment, such as dyes, polyaromatic hydrocarbons, plastics, heavy metals, and pesticides.

NAC-MYB-based transcriptional regulation of secondary cell wall biosynthesis in land plants
Yoshimi Nakano,Masatoshi Yamaguchi,Masatoshi Yamaguchi,Hitoshi Endo,Nur Ardiyana Rejab,Nur Ardiyana Rejab,Misato Ohtani +6 more
TL;DR: Focusing on the NAC-MYB-based transcriptional network, this review discusses the regulatory systems that evolved in land plants to modify the cell wall to serve as a key component of structures that conduct water and provide mechanical support.

Ptr-miR397a is a negative regulator of laccase genes affecting lignin content in Populus trichocarpa.
Shanfa Lu,Quanzi Li,Quanzi Li,Hairong Wei,Mao-Ju Chang,Sermsawat Tunlaya-Anukit,Hoon Kim,Jie Liu,Jingyuan Song,Ying-Hsuan Sun,Lichai Yuan,Ting-Feng Yeh,Ilona Peszlen,John Ralph,Ronald R. Sederoff,Vincent L. Chiang +15 more
TL;DR: A hierarchical genetic regulatory network (GRN) built by a bottom-up graphic Gaussian model algorithm provides additional support for a role of ptr-miR397a as a negative regulator of laccases for lignin biosynthesis in wood formation.

VND-INTERACTING2, a NAC Domain Transcription Factor, Negatively Regulates Xylem Vessel Formation in Arabidopsis
Masatoshi Yamaguchi,Misato Ohtani,Nobutaka Mitsuda,Minoru Kubo,Masaru Ohme-Takagi,Hiroo Fukuda,Taku Demura +6 more
TL;DR: Data suggest that VNI2 regulates xylem cell specification as a transcriptional repressor that interacts with VND proteins and possibly also with other NAC domain proteins.

TL;DR: It is demonstrated that guaiacyl and syringyl lignin subunits are largely dispensable for normal growth and development, and it is suggested that the transcription machinery and signalling pathways responding to cell wall defects may be important targets to include in efforts to reduce biomass recalcitrance.

Mutation of WRKY transcription factors initiates pith secondary wall formation and increases stem biomass in dicotyledonous plants
TL;DR: It is shown that WRKY transcription factors are in part responsible for the parenchymatous nature of the pith cells in dicotyledonous plants and opens up the possibility of significantly increasing the mass of fermentable cell wall components in bioenergy crops.
