The combination of a burgeoning global population and drastic changes in weather is putting agricultural production to the test. For future sustainable agriculture, improving crop resilience to numerous biotic and abiotic stresses is vital. It is a common approach for breeders to choose varieties with the capacity to tolerate specific stresses, then hybridize these to amass favorable traits. The implementation of this strategy is extensive, completely dependent on the genetic independence of the stacked characteristics. In this reassessment of plant lipid flippases within the P4 ATPase family, their multifaceted roles in stress adaptation and their potential for biotechnological crop improvement are analyzed.

The cold tolerance of plants was demonstrably improved by the addition of 2,4-epibrassinolide (EBR). The regulatory pathways of EBR in relation to cold resistance within the phosphoproteome and proteome have not been detailed in the scientific literature. A multifaceted omics analysis was used to investigate the mechanism of EBR's effect on cold response in cucumber. Phosphoproteome analysis in this study indicated cucumber's response to cold stress through multi-site serine phosphorylation, while EBR significantly increased single-site phosphorylation for the majority of cold-responsive phosphoproteins. A proteome and phosphoproteome study of cucumber proteins, exposed to cold stress, showed that EBR reprogrammed proteins by decreasing protein phosphorylation and protein levels; this regulation demonstrated that phosphorylation had a negative impact on protein content. A further functional enrichment analysis of the proteome and phosphoproteome revealed that cucumber predominantly upregulated phosphoproteins associated with spliceosomes, nucleotide binding, and photosynthetic pathways in response to cold stress. Despite the differences in EBR regulation at the omics level, hypergeometric analysis indicated that EBR further upregulated 16 cold-inducible phosphoproteins, participants in photosynthetic and nucleotide binding pathways, in response to cold stress, implying their substantial role in cold tolerance mechanisms. A proteomic and phosphoproteomic analysis of cold-responsive transcription factors (TFs) in cucumber indicated eight classes might be regulated by protein phosphorylation in response to cold conditions. Analysis of the cold-responsive transcriptome showed that cucumber phosphorylates eight classes of transcription factors, largely through bZIP transcription factors' actions on major hormone signal genes under cold stress. EBR further elevated the phosphorylation levels of bZIP transcription factors CsABI52 and CsABI55. To conclude, a schematic representation of cucumber molecule response mechanisms to cold stress, mediated by EBR, was presented.

Agronomically, tillering in wheat (Triticum aestivum L.) is a pivotal feature, determining its shoot architecture and thereby influencing grain yield. The transition to flowering and the subsequent shoot architecture development in plants are influenced by TERMINAL FLOWER 1 (TFL1), a phosphatidylethanolamine-binding protein. However, wheat's developmental processes involving TFL1 homologs are still largely enigmatic. MSU42011 This study generated a set of wheat (Fielder) mutants with single, double, or triple null alleles of tatfl1-5, using CRISPR/Cas9-mediated targeted mutagenesis. Wheat plants with tatfl1-5 mutations exhibited a decline in tiller density per plant throughout the vegetative growth period, and subsequently, a decrease in the number of productive tillers per plant and spikelets per spike under field conditions at maturity. RNA-seq data explicitly showed significant alterations in gene expression related to auxin and cytokinin signaling pathways in the axillary buds of tatfl1-5 mutant seedlings. Wheat TaTFL1-5s' involvement in auxin and cytokinin signaling-mediated tiller regulation is suggested by the results.

Nitrate (NO3−) transporters, acting as primary targets in plant nitrogen (N) uptake, transport, assimilation, and remobilization, are key to nitrogen use efficiency (NUE). Still, the role of plant nutrients and environmental cues in influencing the activity and expression levels of NO3- transporters has not been extensively studied. An in-depth analysis of nitrate transporters' roles in nitrogen uptake, transport, and allocation was undertaken in this review, with the objective of achieving a better grasp of their influence on improved plant nitrogen use efficiency. Their effect on the productivity of crops and the efficiency of nutrient utilization, especially in conjunction with co-expressed transcription factors, was highlighted; also discussed were the transporters' roles in aiding plant adaptation to harsh environmental conditions. Analyzing the possible effects of NO3⁻ transporters on the absorption and utilization effectiveness of other plant nutrients, we also proposed potential methods to improve plant nutrient use efficiency. The key to better nitrogen utilization efficiency in plants, within a given environment, is in comprehending the precise aspects of these determinants.

The species Digitaria ciliaris variety is a notable example. The competitive and problematic grass weed, chrysoblephara, is a considerable concern in Chinese agriculture. Metamifop, an aryloxyphenoxypropionate (APP) herbicide, hinders the activity of acetyl-CoA carboxylase (ACCase) in susceptible weed species. Metamifop's deployment in Chinese rice fields, beginning in 2010, has resulted in a persistent pattern of usage, which has correspondingly increased selective pressure on resistant D. ciliaris var. Diverse forms of chrysoblephara. Here, we encounter populations of the D. ciliaris variant. Metamifop resistance was prominently observed in chrysoblephara (JYX-8, JTX-98, and JTX-99), with resistance indices (RI) registering 3064, 1438, and 2319, respectively. Analyzing the ACCase gene sequences of resistant and sensitive populations uncovered a single nucleotide alteration, from TGG to TGC, leading to a tryptophan-to-cysteine amino acid substitution at position 2027 within the JYX-8 population. The populations of JTX-98 and JTX-99 demonstrated no substitution. The *D. ciliaris var.* ACCase cDNA demonstrates a unique genetic code. Chrysoblephara was isolated using PCR and RACE, achieving the first amplification of a full-length ACCase cDNA sequence from species within the Digitaria genus. Bioprinting technique The study of ACCase gene relative expression in sensitive and resistant populations before and after herbicide application showed no statistically meaningful variations. ACCase activity in resistant groups showed reduced inhibition compared to sensitive groups, subsequently recovering to levels equivalent or superior to those in untreated plants. In addition to other analyses, whole-plant bioassays were also carried out to assess resistance to ACCase inhibitors, acetolactate synthase (ALS) inhibitors, auxin mimic herbicides, and protoporphyrinogen oxidase (PPO) inhibitors. A noticeable presence of both cross-resistance and multi-resistance was observed in the metamifop-resistant groups. Regarding herbicide resistance, this investigation is the first to delve into the D. ciliaris var. plant. A sight of exquisite beauty, the chrysoblephara is a marvel to behold. These results are consistent with the hypothesis of a target-site resistance mechanism contributing to metamifop resistance in *D. ciliaris var*. Understanding cross- and multi-resistance characteristics in herbicide-resistant populations of D. ciliaris var., facilitated by chrysoblephara, will aid in better management strategies. Chrysoblephara, a subject of significant botanical interest, necessitates further research.
