The total yield must be boosted from 3 tons hec<sup>‐1</sup> to 5 tons per hec<sup>‐1</sup> to meet the global food demands by 2050. A major breeding objective is to change the plant architecture to develop varieties suited for intensive agricultural practices and able to withstand climate extremes. Modifying plant architecture could significantly improve productivity; however, it is challenging due to negative associations with key agronomic traits influencing yield. The current research focus of this decade revolves around three critical agronomic variables: tiller number, plant height, and tiller angle. These variables have a significant role in altering plant architecture and ultimately impacting the potential yield. The ideal plant architecture requires moderate planting density, a narrow tiller angle, and reduced plant height, which can be attained through special tiller arrangement. Here, we review the developmental biology and underpinning genetics of the plant architecture traits, especially the genetic factors and environmental factors influencing wheat architecture. The use of crop wild relatives (CWRs), such as <em>Aegilops tauschii,</em> can enhance wheat cultivation by increasing breeding diversity and introgressing beneficial genes into elite wheat germplasm through the recently developed rapid high-throughput introgression (RHI) protocol. Identifying defective mutants and characterizing their corresponding genes will assist us in understanding the molecular mechanism and deploying beneficial alleles to manipulate plant architecture.</div></div>","PeriodicalId":100953,"journal":{"name":"New Crops","volume":"2 ","pages":"Article 100048"},"PeriodicalIF":0.0,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142328261","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, most research has focused on individual histone marks. This study expands on previous work by examining the genome-wide profiles of seven histone marks (H3K9ac, H3K27ac, H3K4me3, H3K36me3, H3K27me3, H2A.Z, and H3K4me2) in sorghum leaves and roots under PEG-induced drought stress. Results revealed that five histone marks (excluding H3K36me3 and H3K27me3) were significantly associated with drought-responsive gene expression. The differential enrichment of these marks may enhance the induction of drought-responsive genes. Specifically, a subset of genes showed multiple histone marks' differential enrichment, with most clade A <em>PP2C</em> genes exhibiting enrichment for four marks after PEG treatment. This suggests a critical role for robust <em>PP2C</em> gene induction in sorghum’s drought response. Additionally, promoter <em>cis</em>-element analysis identified ERF family transcription factors as potential mediators of histone mark enrichment under drought conditions, providing new insights into the interaction between epigenetic modifications and transcriptional regulation in plant stress responses.</div></div>","PeriodicalId":100953,"journal":{"name":"New Crops","volume":"2 ","pages":"Article 100059"},"PeriodicalIF":0.0,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143097920","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite the advantages of NCC, challenges such as limited superior NCC germplasm, coupled with lower strength, yield, pigment instability, and color constraints, have hindered NCC cultivar development. Recent advancements include developing pink cotton through betalain pathway engineering, highlighting biotechnological avenues for enhancing NCC cultivars.

Additionally, they are indispensable for human health as precursors of vitamin A and potent antioxidants, revolutionizing nutrient fortification in numerous crops.

However, the exact molecular mechanisms driving heterosis (hybrid vigor) remain a topic of debate. Maize (<em>Zea mays</em>), which demonstrates pronounced heterosis, serves as an ideal model for studying this phenomenon. In our study, we carefully measured phenotypic changes in ear diameter, tracing its development from the inflorescence meristem (IM) to the floral meristem (FM) stages. Our findings revealed a complex progression: the hybrid's ear diameter followed an additive pattern during the IM and spikelet pair meristem (SPM) stages, shifted to incomplete dominance at the spikelet meristem (SM) stage, and ultimately displayed over-dominance at the FM stage. Notably, significant phenotypic changes occurred during the SM stage with gene expression primarily showing non-additive patterns. Gene Ontology (GO) enrichment analysis highlighted the role of cell redox homeostasis genes, which exhibited over-dominant expression in hybrids, as key contributors to heterosis. Furthermore, we identified a distinct gene expression category—dominant maternal or paternal gene expression in F<sub>1</sub> hybrids (DMP)—characterized by exclusive expression in the hybrid and one parent, while remaining inactive in the other. This category of DMP genes plays a pivotal role in shaping the diverse gene expression patterns observed in hybrids, distinguishing them from their parental lines. In conclusion, the widespread occurrence of non-additive expression seems to enhance the efficiency of biological processes and energy distribution in hybrids, ultimately driving the manifestation of heterosis.</div></div>","PeriodicalId":100953,"journal":{"name":"New Crops","volume":"2 ","pages":"Article 100056"},"PeriodicalIF":0.0,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142744357","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
