To study the regulation of tocochromanol synthesis, Arabidopsis plants were exposed to drought, osmotic stress stimulated by polyethylene glycol, abscisic acid (ABA), nitrogen deprivation, and high light. ABA treatment resulted in increased contents of tocochromanols, and expression of the key tocopherol biosynthesis genes VTE2 and HPPD was upregulated, indicating that tocochromanol accumulation was regulated by ABA. Under drought and osmotic stress, the ABA and tocochromanol contents as well as VTE2 and HPPD expression were also increased. ABA levels did not change during nitrogen deprivation or high light treatment, indicating that tocochromanol accumulation under these conditions was ABA-independent. Tocochromanol accumulation during drought or osmotic stress was not compromised in the ABA-deficient aba1-6, aba2-1 and aba3-2 mutants, suggesting that tocochromanol synthesis under these conditions was mostly regulated in an ABA-independent way.

ABCBs are multi-functional transporter proteins having role in plant adaptation. ATP-binding cassette (ABC) proteins have been known for the transportation of various structurally diverse compounds in all kingdoms of life. Plants possess a particularly high number of ABC transporters compared to other eukaryotes: the most abundant being ABCG followed by the ABCB subfamilies. While members of the ABCB subfamily are primarily known for auxin transportation, however, studies have shown their involvement in variety of other functions viz. growth and development, biotic and abiotic stresses, metal toxicity and homeostasis, cellular redox state stability, stomatal regulation, cell shape maintenance, and transport of secondary metabolites and phytohormones. These proteins are able to perform various biological processes due to their widespread localization in the plasma membrane, mitochondrial membrane, chloroplast, and tonoplast facilitating membrane transport influenced by various environmental and biological cues. The current review compiles published insights into the role of ABCB transporters, and also provides brief insights into the role of ABCB transporters in a medicinal plant, where the synthesis of its bioactive secondary metabolite is linked to the primary function of ABCBs, i.e., auxin transport.

Seed dormancy is a crucial survival strategy for plants to cope with environmental stresses. High levels of seed dormancy result in uneven germination, while low levels of seed dormancy increase the risk of pre-harvest sprouting (PHS), which threatens crop yield and quality. Therefore, achieving the optimal balance between seed dormancy and germination is vital for maximum potential crop yield and quality. This study constructed dynamic transcriptome expression profiles of the germination process for the weakly dormant wheat variety Jing 411 (J411) and the strongly dormant landrace variety Hongsuibai (HSB), revealing the temporal expression of differentially expressed genes. Plant hormone-related genes played a crucial role in the early germination response, particularly the abscisic acid (ABA) signaling gene TaABI5 and the ABA catabolism gene TaCYP707A1. The late embryogenesis abundant (LEA) protein family genes exhibited differential expression patterns during the germination of seeds with varying levels of dormancy. The TaSMP1 gene, a member of the LEA protein family, was identified as a negative regulator of seed dormancy, interacting directly with the key transcription factor TaABI5 in the ABA signaling pathway and influencing the expression of the seed germination gene TaDOG1L1.

In combination with machine learning, network biology can dramatically accelerate the pace of gene discovery using modern transcriptomics approaches and be validated via genome editing technology for improving crops to stresses.

The cumulative effects of combined stresses can significantly influence both plant growth and yields. In navigating the complexities of climate change, ensuring the nourishment of our growing population hinges on implementing precise agricultural systems. Conventional breeding methods have been commonly employed; however, their efficacy has been impeded by limitations in terms of time, cost, and infrastructure. Cutting-edge tools focussing on big data are being championed to usher in a new era in stress biology, aiming to cultivate crops that exhibit enhanced resilience to multifactorial stresses. Transcriptomics, combined with network biology and machine learning, is proving to be a powerful approach for identifying potential genes to target for gene editing, specifically to enhance stress tolerance. The integration of transcriptomic data with genome editing can yield significant benefits, such as gaining insights into gene function by modifying or manipulating of specific genes in the target plant.

RNA-seq-derived SNP datasets hold the potential to trace geographic origins of the core germplasm. The Rheum palmatum complex, the source plant of rhubarb, has been widely used for centuries due to its diverse functions in clinical treatments. However, the wild resources of rhubarb are currently declining and even facing depletion. Therefore, revealing the genetic background of the R. palmatum complex within the top-geoherb area is important for the efficient utilization and conservation of its wild resources. In this study, population transcriptomic analyses were conducted to assess the genetic diversity and gene expression diversity of different populations in the R. palmatum complex within the top-geoherb area. Candidate single nucleotide polymorphisms (SNPs) were identified as specific molecular markers for tracing the origin of the R. palmatum complex from various top-geoherb areas. Based on the reference genome, a total of 30,480 transcripts and 100,966 SNPs were generated across 82 individuals from 17 populations of the R. palmatum complex. Moderate genetic differentiation was detected for the two genetic lineages of the R. palmatum complex derived from the top-geoherb area. Fourteen genes encoding key enzymes were differentially expressed between two genetic lineages. Besides, 26 specific SNPs located on the genes involved in the biosynthesis of the active components were screened out, and these SNPs were highly differentiated between 2 genetic lineages. A large-scale reference-based assembly transcriptome of the R. palmatum complex from the top-geoherb area provided insights into the genetic divergence and expression differentiation of genetic lineages.

In this study, we investigated the potential role of miRNA in poplar roots under LN stress using miRNA-seq. 305 conserved miRNAs belonging to 48 miRNA families were identified, and 15 novel miRNAs were predicted.

Over the past decade, research has revealed ribosome subgroups respond to adverse conditions, suggesting that this tight coordination may be grounded in the induction of ribosome variants resulting in differential translation outcomes.
