Syntrichia caninervis is a desiccation tolerant moss and the dominant bryophyte found in biological soil crusts Gurbantunggut desert. In this study, we assessed transcriptome profiles of S. gametophytes during dehydration-rehydration (D-R) process (across 9 time points) using Illumina sequencing. total, 22489 transcripts were identified, including 5337 novel transcripts, that mapped to reference genome. A total 12548 exhibited significant alterations D-R samples compared with control samples. The differentially expressed (DETs) possessed several enriched Gene Ontology terms, such as "water stress response", "oxidation-reduction process", "membrane metabolism", "photosynthesis", "transcription factor activity". Moreover, early dehydration stress, DETs significantly stress-related pathways from Kyoto Encyclopedia Genes Genomes, "phenylpropanoid biosynthesis", "alpha-linolenic acid "fructose mannose metabolism". Photosynthesis-related (e.g., ScPsa H, ScRubisco, ScLhcb1) inhibited treatment accumulated late rehydration period. Most embryogenesis abundant proteins (LEA) light-inducible protein (ELIP) families strongly at stage. These positively correlated content changes absolute water Fv/Fm values, alongside peroxidase superoxide dismutase activities. Seven transcription families, AP2-ERF, bHLH, G2-like, MYB, NAC, WRKY, bZIP, treatment. This study first analysis genome for gene annotation multigroup points.

With the climate constantly changing, plants suffer more frequently from various abiotic and biotic stresses. However, they have evolved biosynthetic machinery to survive in stressful environmental conditions. Flavonoids are involved a variety of biological activities plants, which can protect different (plant-parasitic nematodes, fungi bacteria) stresses (salt stress, drought UV, higher lower temperatures). contain several subgroups, including anthocyanidins, flavonols, flavones, flavanols, flavanones, chalcones, dihydrochalcones dihydroflavonols, widely distributed plants. As pathway flavonoid biosynthesis has been well studied, many researchers applied transgenic technologies order explore molecular mechanism genes associated with biosynthesis; as such, shown stress tolerance through regulation content. In present review, classification, structure flavonoids were summarized, roles under forms also included. addition, effect applying on enhancement plant was discussed.

Summary Drought stress limits wheat production and threatens food security world‐wide. While ethylene‐responsive factors (ERFs) are known to regulate plant response drought stress, the regulatory mechanisms responsible for a tolerant phenotype remain unclear. Here, we describe positive role of TaERF87 in mediating tolerance stress. overexpression (OE) enhances tolerance, while silencing leads sensitivity wheat. RNA sequencing with biochemical assays revealed that activates expression proline biosynthesis genes TaP5CS1 TaP5CR1 via direct binding GCC‐box elements. Furthermore, accumulates higher levels ‐ ‐OE lines than wild‐type plants under well‐watered conditions concomitantly enhanced these transgenic lines. Moreover, interaction between bHLH transcription factor TaAKS1 synergistically transcriptional activation. OE also increases by promoting accumulation. Additionally, our findings verified targets abscisic acid‐responsive element 2 (TaABF2). Together, study elucidates underlying mediated TaABF2–TaERF87/TaAKS1–TaP5CS1/TaP5CR1 module, identifies candidate development elite drought‐tolerant varieties.

The basic helix-loop-helix (bHLH) transcription factors play important physiological functions in the processes of plant growth, development, and response to abiotic stresses. However, a comprehensive genome-scale study ginger bHLH gene family has not been documented. In this study, 142 ZobHLH genes were identified genome. Using Arabidopsis proteins as reference, classified into 15 subfamilies unevenly distributed on 11 chromosomes ginger. Sequence characterization, multiple sequence alignment, phylogenetic analysis, conserved protein motifs exon-intron distribution patterns conducted further analyze evolutionary relationships among these proteins. results duplicated event analysis demonstrated that pivotal role segment duplication promoting expansion family. Additionally, cis-regulatory elements well interaction networks indicated potential involvement growth adversity stress. RNA-seq RT-qPCR showed ZobHLH083 ZobHLH108 key roles salt stress waterlogging stress, respectively. we systematically analyzed characteristics ginger, discovering critical rhizome present provides theoretical foundation for research ZobHLHs will help explore functional properties genes.

Selective breeding based on diversity not keeping growing food feed. emergence contemporary plant engineering, genome-editing, synthetic biology offer precise tools crops can sustain productivity under stress conditions. Here, we summarize systems biology-level understanding regulatory pathways involved perception, signalling, protective processes activated response unfavourable The potential role noncoding RNAs regulation abiotic responses has also been highlighted. Further, examples imparting engineering are discussed. Additionally, provide perspectives rational design through list various bioparts be used gene circuits whose stress-protective functions switched on/off cues.

Biotic stresses threaten to destabilize global food security and cause major losses crop yield worldwide. In response pest pathogen attacks, plants trigger many adaptive cellular, morphological, physiological, metabolic changes. One of the crucial stress-induced responses is synthesis accumulation plant secondary metabolites (PSMs). PSMs mitigate adverse effects stress by maintaining normal physiological functioning plants, thereby providing tolerance. This differential production tightly orchestrated master regulatory elements, Transcription factors (TFs) express differentially or undergo transcriptional translational modifications during conditions influence PSMs. Amongst others, microRNAs, a class small, non-coding RNA molecules that regulate gene expression post-transcriptionally, also play vital role in controlling such TFs. The present review summarizes stress-inducible TFs synthesizing accumulating highlights how miRNAs fine-tune various stress-responsive transcription biotic stress.

Anthocyanins are plant-based pigments that primarily present in berries, grapes, purple yam, corn and black rice. The research on fruit with a high anthocyanin content is not sufficiently extensive. Considering its crucial role nutrition health it vital to conduct further studies how accumulates explore potential for edible medicinal purposes. Anthocyanin biosynthesis plays an important maize stems (corn). Several beneficial compounds, particularly cyanidin-3-O-glucoside, perlagonidin-3-O-glucoside, peonidin 3-O-glucoside, their malonylated derivatives have been identified. C1, C2, Pl1, Pl2, Sh2, ZmCOP1 ZmHY5 harbored functional alleles played the of anthocyanins maize. Sh2 gene regulates sugar-to-starch conversion, thereby influencing kernel quality nutritional content. key regulatory genes control light responses photomorphogenesis. This review concludes molecular identification all encoding structural enzymes pathway by describing cloning characterization these genes.

Plant viral diseases compromise the growth and yield of crop globally, they tend to be more serious under extreme temperatures drought climate changes. Currently, regulatory dynamics during plant development in response virus infection at cell level remain largely unknown. In this study, single-cell RNA sequencing on 23 226 individual cells from healthy tomato chlorosis virus-infected leaves was established. The specific expression epigenetic landscape each type stage were depicted. Notably, mesophyll showed a rapid function transition leaves, which is consistent with pathological changes such as thinner decreased chloroplast lamella samples. Interestingly, F-box protein SKIP2 identified play pivotal role chlorophyll maintenance plants. Knockout SlSKIP2 greener leaf state before after infection. Moreover, we further demonstrated that located cytomembrane nucleus directly regulated by ERF4. conclusion, detailed insights into responses infections cellular level, our study provides genetic framework gene reference plant-virus interaction breeding future research.
