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}

Soybean, the leading dietary protein and oil content crop in animal feed, also provides humans with 30% of their dietary fat intake and contributes to 67% of global protein powder consumption annually. 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. We aim to inspire the researchers in salt-tolerant breeding and research to new frontiers.</div></div>","PeriodicalId":100953,"journal":{"name":"New Crops","volume":"3 ","pages":"Article 100079"},"PeriodicalIF":0.0,"publicationDate":"2025-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144622789","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}

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}

Transcriptional analysis revealed significant induction of <em>ZmASR6</em> under salt stress over 24 hours. Subcellular localization experiments confirmed ZmASR6 protein presence in the nucleus and cytoplasm of maize protoplasts. Using CRISPR/Cas9, we generated <em>ZmASR6</em> knockout lines, which displayed reduced salt tolerance compared to wild-type (WT) plants.
