And Function

The elaboration of plant form and function depends on the ability of a plant cell to divide and differentiate. The decisions of individual cells to enter the cell cycle, maintain proliferation competence, become quiescent, expand, differentiate, or die depend on cell-to-cell communication and on the perception of various signals. These signals can include hormones, nutrients, light, temperature, and internal positional and developmental cues. In recent years, progress has been made in understanding the molecular control of plant pattern formation, especially in the model plant Arabidopsis thaliana. Furthermore, specific genes have been found that are necessary for normal pattern formation and the control of the rates of cell division and differentiation. Cloning of these genes is revealing the molecular basis of plant pattern formation and the key players on plant signal transduction systems.

Abstract Selenium (Se) can promote the growth and resistance of agricultural crops as fertilizers, while the role of nano-selenium (nano-Se) against Cd remains unclear in pepper plants (Capsicum annuum L.). Biofortification with nano-Se observably restored Cd stress by decreasing the level of Cd in plant tissues and boosting the accumulation in biomass. The Se compounds transformed by nano-Se were primarily in the form of SeMet and MeSeCys in pepper tissues. Differential metabolites and the genes of plant signal transduction and lignin biosynthesis were measured by employing transcriptomics and determining target metabolites. The number of lignin-related genes (PAL, CAD, 4CL, and COMT) and contents of metabolites (sinapyl alcohol, phenylalanine, p-coumaryl alcohol, caffeyl alcohol, and coniferaldehyde) were remarkably enhanced by treatment with Cd1Se0.2, thus, maintaining the integrity of cell walls in the roots. It also enhanced signal transduction by plant hormones and responsive resistance by inducing the biosynthesis of genes (BZR1, LOX3, and NCDE1) and metabolites (brassinolide, abscisic acid, and jasmonic acid) in the roots and leaves. In general, this study can enable a better understanding of the protective mechanism of nano-Se in improving the capacity of plants to resist environmental stress.

N Starvation

Abstract Background: Nitrogen (N) is one of the main factors limiting the wood yield in poplar cultivation. Understanding the molecular mechanism of N utilization could play a guiding role in improving the nitrogen use efficiency (NUE). Results: In this study, three N-efficient genotypes (A) and three N-inefficient genotypes (C) of Populus deltoides were cultured under low N stress (5 μM NH4NO3) and normal N supply (750 μM NH4NO3). The dry matter mass, leaf morphology, and chlorophyll content of both genotypes decreased under N starvation. Interestingly, N starvation induced fine root growth in A, but not in C. Next, a detailed time-course analysis of enzyme activities and gene expression in leaves identified 2,062 differentially expressed genes (DEGs) in A and 1,118 in C, most of which were up-regulated. Moreover, the sensitivity to N starvation of A was weak, and DEGs related to hormone signal transduction played an important role in the low N response in A. The weighted gene co-expression network analysis identified genes related to membrane, catalytic activity, enzymatic activity, and response to stresses might be critical for poplar’s adaption to N starvation and these genes participated in the negative regulation of various biological processes. Finally, ten influential hub genes and twelve transcription factors were identified in the response to N starvation, among them Podel.19G001200, Podel.19G035300, Podel.02G021400, and Podel.04G076900 were related to programmed cell death, and the defense response, and PodelWRKY41, PodelWRKY75, PodelWRKY18, PodelBHLH25, PodelBHLH30, PodelBHLH, and PodelHY5 were involved in plant signal transduction.Conclusions: Under the condition of N starvation, A showed stronger adaptability and a better NUE than C in morphology and physiology. The discovery of hub genes and TFs provided a new information for the analysis of the molecular mechanism of N efficient utilization and the improvement of NUE of poplar.
