However, little information has been uncovered about the <em>F3H</em> gene family in maize (<em>Zea mays</em>) to date. In this study, 15 <em>ZmF3H</em> genes were identified in the maize genome and clustered into four phylogenetic groups with homologs from other plant species. Expression profile analysis revealed that most <em>ZmF3H</em> genes exhibited differential expression patterns across various maize tissues. qRT-PCR expression analysis of <em>ZmF3H</em> genes under salt treatment identified <em>ZmF3H6</em> as an excellent candidate gene for salt resistance. Overexpression of <em>ZmF3H6</em> in <em>Arabidopsis</em> led to increased tolerance to salt stress, possibly by enhancing flavonol accumulation and antioxidant capacity. Conversely, a mutation in the sequence of <em>ZmF3H6</em> resulted in compromised salt tolerance of maize seedlings. Molecular docking identified that ZmF3H6 binds to naringenin at specific amino acid residues necessary for hydroxylation. Dual-luciferase reporter and electrophoretic mobility shift assays demonstrated that the transcription factor ZmMYB33 activates <em>ZmF3H6</em> expression by binding to the MBS domains in the <em>ZmF3H6</em> promoter. Our findings provide a foundation for further investigation into the roles of the <em>ZmF3H</em> genes in plant abiotic stress responses and present a novel genetic resource for creating salt-resistant maize.</div></div>","PeriodicalId":100953,"journal":{"name":"New Crops","volume":"3 ","pages":"Article 100082"},"PeriodicalIF":0.0,"publicationDate":"2025-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145048588","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Both current and previous studies have indicated a lack of correlation between fiber length and gene expression dynamics, underscoring the importance of phenotyping fiber elongation. Traditional methods for measuring fiber length, however, tend to be impractical and labor-intensive, particularly for developing fibers that are fragile and prone to twisting. In this study, we present an innovative phenotyping method to measure the elongation of developing cotton fibers. Our key findings reveal a strong linear relationship between the total volume of fiber bundles and fiber length. This relationship allows for the straightforward estimation of the linear correlation coefficient from the final fiber length and the final volume of the fiber bundle within a boll. Upon measuring both the fiber bundle volume and fiber length, we discovered that their growth dynamics were well-represented by a logistic curve. Additionally, the expression dynamics of several newly identified genes demonstrated a significant positive correlation with the rate of fiber elongation. This research marks an important advancement in quantifying gene expression dynamics and fiber elongation. We believe that measuring the elongation of developing fibers will greatly accelerate the development of high-quality cotton varieties and enhance our understanding of plant developmental biology.</div></div>","PeriodicalId":100953,"journal":{"name":"New Crops","volume":"3 ","pages":"Article 100080"},"PeriodicalIF":0.0,"publicationDate":"2025-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144570490","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The improvement and utilization of saline-alkaline land can expand arable land for soybean production and decrease the yield penalty, ensuring food security for the growing world population. Over the past decades, identifying salt-tolerant cultivars and understanding salt stress signaling and responses in soybeans have made some progress. However, few successful studies about improved soybean field performance have been reported. Here, we provide recent advances in functionally characterized genes and major quantitative trait loci (QTLs) contributing to soybean salt tolerance. We focus on the strategies that we could take to achieve salt-tolerant soybean cultivars with high-yield, which includes unveiling the underlying cellular and molecular mechanisms that regulate the soybean response to high pH alkaline stress, to gain better knowledge of the soybean circadian clock and time-gate the response to saline-alkaline stress and minimize the fitness cost, and lay out the audacious plans to make soybean a halophyte.

The silique length of line DR5 exceeds that of lines DR2 and DR4. The DAALs also display significantly reduced silique width and beak length compared to their parental lines. Regarding pollen viability, thousand seed weight, and seeds per pod, the DAALs demonstrate superior performance relative to the MAALs. Furthermore, the seeds from line DR4 are larger than those of the parental <em>B. napus</em>. Cytological observations indicate that the chromosome behavior of the DAALs is regular, with 20 bivalents encompassing 10 II<sup>A-A</sup>, 9 II<sup>C-C</sup>, and 1 II<sup>R-R</sup>. At anaphase I, an even distribution of chromosomes to both sides of the pollen mother cells (PMCs) is observed in the DAALs.

Researchers have identified several domestication genes in maize, such as <em>TEOSINTE BRANCHED1 (TB1)</em>, <em>GRASSY TILLERS1 (GT1), TASSELS REPLACE UPPER EARS1 (TRU1)</em>, and <em>TEOSINTE GLUME ARCHITECTURE1 (TGA1)</em>, but little is known about higher-tier regulatory genes. Recent research by Dong and colleagues identified <em>TASSELSHEATH4 (TSH4)</em>, a previously characterized gene that establishes developmental boundaries in maize, as a central player in maize domestication. Using recombinant inbred lines (RILs) and teosinte nested association mapping (TeoNAM) populations, the authors mapped <em>TSH4</em> to a locus that controls key domestication traits. Functional analysis revealed that <em>TSH4</em>, along with its paralogs <em>UNBRANCHED2</em> (<em>UB2</em>) and <em>UB3</em>, regulates the formation of vegetative and reproductive boundaries. Additionally, TSH4 targets known domestication genes, such as <em>TB1</em>, <em>TRU1</em>, and <em>TGA1</em>, demonstrating its central role in shaping the architecture of modern maize. This work identifies <em>TSH4</em> as a key component of the domestication regulatory network and advances our understanding of the genetic mechanisms driving domestication and developmental boundary formation in plants.</div></div>","PeriodicalId":100953,"journal":{"name":"New Crops","volume":"2 ","pages":"Article 100068"},"PeriodicalIF":0.0,"publicationDate":"2025-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143600879","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}
