Peanut seed pods develop below ground from a gynophore that forms above ground and then penetrates the soil surface to bury the developing pod. Numerous studies have explored transcriptional regulation during peanut pod development. Here, we explored post-transcriptional regulation, including polyadenylation, alternative splicing, and RNA adenosine methylation (m⁶A), in peanut pods across four developmental stages by performing direct RNA sequencing. This produced 70.43 million long reads with average lengths of 890–1,136 nucleotides (nt) from 12 samples across four developmental stages, yielding a total of 14,627 newly identified transcripts. We detected a negative relationship between poly(A) tail lengths and transcript abundance, with the shortest poly(A) tails at the subterranean peg and expanded pod 1 stages, and longest poly(A) tails at the aerial gynophore and expanded pod 2 stages. Moreover, throughout pod development, from the penetration of the gynophore into the soil to pod enlargement, the splicing machinery utilized more proximal than distal alternative polyadenylation sites in the transcripts. The date showed no correlation between m⁶A modification and gene expression in peanut, but found more transcripts with alternative first and last exon types of alternative splicing events. Transcripts that were differentially abundant across developmental stages were primarily enriched in the Gene Ontology terms photosynthesis, response to oxidative stress, response to auxin, plant-type cell wall organization, and lignin catabolism. This study lays a foundation for revealing the roles of epigenetics and post-transcriptional regulation in pod development in peanut. </p></div>","PeriodicalId":53135,"journal":{"name":"aBIOTECH","volume":"6 3","pages":"554 - 568"},"PeriodicalIF":5.0,"publicationDate":"2025-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s42994-025-00224-5.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145100600","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, its potential remains untapped due to the limited availability of short-duration, high-yielding varieties capable of outcompeting other <em>rabi</em> crops. Considering this notion, we have evaluated twenty-one F₂ and six BC₁F₁ populations derived from seven diversified parents of <em>B</em><em>rassica</em> <em>juncea</em> following a Randomized Complete Block Design at Sher-e-Bangla Agricultural University. Based on key agronomic traits, the genetic components, heterosis, inbreeding depression, and gene action were studied to select early maturing and high-yielding populations. The percentage of heterosis was manifested in various cross-combinations, including P4 ​× ​P6 (91.45% for yield per plant) and P5 ​× ​P6 (28.52% for thousand seed weight), emerging as promising candidates for increasing productivity while managing negative inbreeding effects. Conversely, significant inbreeding depression was noted in traits like days to siliquae maturity and yield, particularly in crosses, P1 ​× ​P2 (6.29%) and P3 ​× ​P5 (21.74%), underscoring the need for careful selection in breeding programs to mitigate these effects. Variance analysis indicated that both additive and non-additive genetic interactions play a pivotal role in the inheritance patterns of the traits of interest. Among the six backcrosses, one promising line was (P5 ​× ​P6) ​× ​P5, demonstrating early maturity (107.00 DAS) with improved seed yield (12.47 ​g). This combination exhibited the potential for enhancing the adaptability and productivity by maintaining the maturity index and accelerating yield. Furthermore, significant phenotypic variation across yield-contributing traits was notable, whereas thousand seed weight and yield per plant showed high broad-sense and narrow-sense of heritability. Besides, positive correlations between seed yield and its attributing traits were noted, suggesting potential avenues for selection breeding.

The effects of five different particle size variations on the physicochemical characteristics, dough, and steamed bread structure of Flaxseed-based milk coproduct (FMC) were investigated. As the particle size decreases, the structure of the dough becomes denser due to an increase in water retention capacity and dissolution capacity, weakening the competition for dough moisture and allowing for an increase in air-holding capacity. The reduction in particle size increased the specific volume of the steamed bread, a decrease in the spread ratio, and an optimization of hardness and elasticity, as well as an increase in consumer acceptance of the FMC steamed bread. However, it is not the smaller the particle size, the higher the quality of steamed bread, appropriate reduction of particle size can improve the quality of steamed bread.
