Review: The two faces of IRE1 and their role in protecting plants from stress Plant Sci. (IF 3.591) Pub Date : 2020-11-18 Zhaoxia Li; Stephen H. Howell
IRE1 is a key factor in the Unfolded Protein Response (UPR) in plants. IRE1 is a single-pass transmembrane protein that has a lumenal domain (LD) and cytoplasmic domain (CD), which perform quite different tasks on different sides of the ER membrane. The LD recognizes the presence of misfolded proteins in the ER lumen. The LDs of IRE1 in different plant species are predicted to fold into β-propeller

Genetic analysis of maize shank length by QTL mapping in three recombinant inbred line populations Plant Sci. (IF 3.591) Pub Date : 2020-11-22 Meiling Liu; Wenshu He; Ao Zhang; Lijun Zhang; Daqiu Sun; Yuan Gao; Pengzun Ni; Xinglin Ma; Zhenhai Cui; Yanye Ruan
In maize, the shank is a unique tissue linking the stem to the ear. Shank length (SL) mainly affects the transport of photosynthetic products to the ear and the dehydration of kernels via regulated husk morphology. The limited studies on SL revealed it is a highly heritable quantitative trait controlled by significant additive and additive-dominance effects. However, the genetic basis of SL remains

Cryptochrome 1a of tomato mediates long-distance signaling of soil water deficit Plant Sci. (IF 3.591) Pub Date : 2020-11-19 Victor D’Amico-Damião; Ian C. Dodd; Reginaldo Oliveira; José C.B. Lúcio; Davi R. Rossatto; Rogério F. Carvalho
Although the blue light photoreceptors cryptochromes mediate the expression of genes related to reactive oxygen species, whether cryptochrome 1a (cry1a) regulates local and long-distance signaling of water deficit in tomato (Solanum lycopersicum L.) is unknown. Thus the cry1a tomato mutant and its wild-type (WT) were reciprocally grafted (WT/WT; cry1a/cry1a; WT/cry1a; cry1a/WT; as scion/rootstock)

A Paeonia ostii caffeoyl-CoA O-methyltransferase confers drought stress tolerance by promoting lignin synthesis and ROS scavenging Plant Sci. (IF 3.591) Pub Date : 2020-11-20 Daqiu Zhao; Yuting Luan; Wenbo Shi; Xiayan Zhang; Jiasong Meng; Jun Tao
Paeonia ostii is an emerging woody oil crop, but drought severely inhibits its growth and promotion in arid or semiarid areas, and little is known about the mechanism governing this inhibition. In this study, the full-length cDNA of a caffeoyl-CoA O-methyltransferase gene (CCoAOMT) from P. ostii was isolated, and determined to be comprised of 987 bp. PoCCoAOMT encoded a 247-amino acid protein, which

A tomato dynein light chain gene SlLC6D is a negative regulator of chilling stress Plant Sci. (IF 3.591) Pub Date : 2020-11-18 Tixu Hu; Shufeng Wang; Qi Wang; Xin Xu; Qiqi Wang; Xiangqiang Zhan
Dynein light chain (DLC) proteins are an important component of dynein complexes, which are widely distributed in plants and animals and involved in a variety of cellular processes. The functions of DLC genes in plant chilling stress remain unclear. In this study, we isolated a DLC gene from tomato, designated SlLC6D. Promoter analysis revealed many cis-elements involved in abiotic stress in the SlLC6D

Abscisic acid-mediated induction of FLAVIN-CONTAINING MONOOXYGENASE 2 leads to reduced accumulation of methylthioalkyl glucosinolates in Arabidopsis thaliana Plant Sci. (IF 3.591) Pub Date : 2020-11-18 Yimeng Li; Rui Li; Yuji Sawada; Surina Boerzhijin; Ayuko Kuwahara; Muneo Sato; Masami Yokota Hirai
Side-chain modification contributes to the structural diversity of aliphatic glucosinolates (GSLs), a class of sulfur-containing secondary metabolites found in Brassicales. The first step in side-chain modification of aliphatic GSLs is the S-oxygenation of the methylthioalkyl (MT) moiety to the methylsulfinylalkyl (MS) moiety. This reaction is catalyzed by flavin-containing monooxygenase (FMOGS-OX)

Melatonin antagonizes ABA action to promote seed germination by regulating Ca2+ efflux and H2O2 accumulation Plant Sci. (IF 3.591) Pub Date : 2020-11-17 Hao Li; Yanliang Guo; Zhixiang Lan; Zixing Zhang; Golam Jalal Ahammed; Jingjing Chang; Yong Zhang; Chunhua Wei; Xian Zhang
Seed germination is a vital stage in the plant life-cycle that greatly contributes to plant establishment. Melatonin has been shown to promote seed germination under various environmental stresses; however, the mechanism remains largely underexplored. Here, we reported that melatonin antagonized abscisic acid (ABA) to promote seed germination by regulating ABA and gibberellic acid (GA3) balance. Transcriptomic

Developmental roles of Auxin Binding Protein 1 in Arabidopsis thaliana Plant Sci. (IF 3.591) Pub Date : 2020-11-13 Zuzana Gelová; Michelle Gallei; Markéta Pernisová; Géraldine Brunoud; Xixi Zhang; Matouš Glanc; Lanxin Li; Jaroslav Michalko; Zlata Pavlovičová; Inge Verstraeten; Huibin Han; Jakub Hajný; Robert Hauschild; Milada Čovanová; Marta Zwiewka; Lukas Hoermayer; Matyáš Fendrych; Tongda Xu; Jiří Friml
Auxin is a major plant growth regulator, but current models on auxin perception and signaling cannot explain the whole plethora of auxin effects, in particular those associated with rapid responses. A possible candidate for a component of additional auxin perception mechanisms is the AUXIN BINDING PROTEIN 1 (ABP1), whose function in planta remains unclear. Here we combined expression analysis with

COP1 mediates light-dependent regulation of flavonol biosynthesis through HY5 in Arabidopsis Plant Sci. (IF 3.591) Pub Date : 2020-11-16 Chitra Bhatia; Subhash Reddy Gaddam; Ashutosh Pandey; Prabodh Kumar Trivedi
Flavonols, a class of flavonoids, accumulate as protective agents in response to various stresses. Among various environmental stimuli, light is one of the factors regulating flavonol production. MYB12/11/111, members of the R2R3 MYBs family, regulates spatio-temporal flavonol accumulation in Arabidopsis. Although various studies indicate at the involvement of an E3 ubiquitin ligase CONSTITU
