Successful terrestrialization required evolutionary adaptations to harsh and fluctuating light conditions, where direct irradiation is stronger than in aquatic environments. To cope with these challenges, plants evolved regulatory mechanisms to control cellular activities. One such acclimation is rapidly reversible, energy-dependent non-photochemical quenching (NPQ), which dissipates excess light energy as heat to protect the photosynthetic apparatus. Another critical innovation is abscisic acid (ABA) signaling, believed to have first emerged in bryophytes. Here, we reveal a potential link between these two key acclimations in bryophytes. We demonstrate that exogenous ABA induces NPQ in the moss Physcomitrium patens, increasing the levels of LHCSR, a key NPQ regulator, while concurrently decreasing PsbS. Exogenous ABA also enhances the xanthophyll cycle pigments, contributing to NPQ. In mutants deficient in ABA signaling components, including SNF1-related kinase 2 (SnRK2) and the transcription factor, Abscisic Acid-Insensitive 3 (ABI3), ABA-induced NPQ, LHCSR and PsbS expression, and xanthophyll cycle pigment accumulation were significantly reduced. These findings suggest that exogenous ABA enhances NPQ through the SnRK2 and ABI3-mediated signaling pathway by promoting LHCSR expression and xanthophyll cycle pigment production. We propose that the integration of ABA signaling and NPQ represent a critical evolutionary milestone, enabling early land plants to adapt and thrive in terrestrial environments.","PeriodicalId":16813,"journal":{"name":"Journal of Plant Research","volume":" ","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143795742","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Xinjiang garlic exhibits visually normal development of both androecium and gynoecium, but most pollen grains are not viable, thus allowing for the identification of flower development-related genes through combined morphological, anatomical, and cytological methods with transcriptome analysis. The inflorescence meristem differentiation of Xinjiang garlic plants was initiated after the 6th-7th leaves emerged, implying the transition from vegetative growth to reproductive growth. With the development of flower organs after bolting, normal pollen mother cell meiosis but no viable pollen grains were detected through triphenyl tetrazolium chloride (TTC) staining. Delayed tapetal degeneration, the gap between the tapetum and the middle layer, and degenerating and aborting anther are visible during anther development. There were 25 differentially expressed MYB genes and 64 flowering pathway related genes at different stages of flower development. The R2R3-MYB genes enriched in Module 22 are involved in the development of the tapetum and pollen. The co-expression network analysis showed that most MYB genes are related to flowering regulatory genes. The expression pattern of MYB35, MYB26, MYB80 and MMD1 may cause delayed degradation of the tapetum, or abnormal development of the pollen wall leading to pollen abortion.","PeriodicalId":16813,"journal":{"name":"Journal of Plant Research","volume":" ","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143795749","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we investigate the evolution and function of wax ester biosynthesis in land plants, focusing on the WSD (wax synthase/DGAT) enzyme family. We demonstrate that the ancestral origin of WSD enzymes traces back to streptophyte algae, specifically Klebsormidium nitens (KnWSD1). Our findings provide evidence that KnWSD1 functions as a monofunctional WSD catalyzing WE formation without producing triacylglycerols (TAGs). By generating Arabidopsis mutants with multiple WSD gene knockouts, we uncover a crucial role for WEs in supporting floral organ development under high humidity. Our results reveal that WEs are essential for floral organ development and provide new insights into their evolutionary significance in plant adaptation to terrestrial environments.","PeriodicalId":16813,"journal":{"name":"Journal of Plant Research","volume":" ","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143763504","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among papilionoids, a group characterized by flag-flowers, early-branching species often deviate from this typical pattern. This study investigates Myroxylon peruiferum L.f., an early-branching papilionoid legume native to the Brazilian Atlantic Forest, with non-papilionaceous flowers. Through detailed macromorphological, anatomical, histochemical, and ultrastructural analyses of floral organs, we reveal new insights into pollen release and presentation mechanisms in legumes. Pollen is released through an unusual process: the anther opens via an apical wide slit that gradually extends toward the base, releasing pollen in stages. Ducts in the sepals, petals, ovary, and anther secrete translucent oleoresin droplets that harden when released into the external environment. These serve multiple functions, including enhancing flower visibility, facilitating secondary pollen presentation by attaching pollen to the anther apex and petal tips, and acting as olfactory attractants due to their terpene content. M. peruiferum presents several unique traits not previously described in this subclade, including (a) oleoresin overflow through anther pores, (b) uncommon rimose anther dehiscence, and (c) a novel form of secondary pollen presentation via oleoresin drops. These findings provide important new insights into the reproductive strategy of this species and offer broader implications for legume biology.","PeriodicalId":16813,"journal":{"name":"Journal of Plant Research","volume":" ","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143743048","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In a previous study, Trichoderma biofertilizer activated the MsERF105 transcription factor (TF), which further enhanced the resistance of Malus sieversii against Alternaria alternata f. sp. mali, but how resistance signals are transmitted is still unknown. In this study, it was found that the MsERF105-centered disease-resistant regulatory network was induced by Trichoderma in M. sieversii. The TF-centered yeast one-hybrid indicated that WRKY33 and WRKY40 bound to WBOXATNPR1 elements and GT1 bound to GT1CONSENSUS elements in the promoter of MsERF105 to activate its expression. In addition, the proteins that interacted with MsERF105 were identified by yeast two-hybrid, including FUBP2 and HSP17.8. Furthermore, the candidate target genes of MsERF105 were screened using RNA-Seq, and yeast one-hybrid and tobacco transient transformation further showed MsERF105 bound to GCCBOX elements to regulate the expression of bHLH162, ERF017, NAC83 and NAC104; bound to CCAATBOX elements to regulate the expression of HSFs, HSP70s and HSP20; and bound to ERS elements to regulate the expression of DRPs.

To feed the growing population, molecular breeders aim to increase grain yield. Grain size is an important factor for crop productivity, and it has been extensively studied. However, molecular breeders face a major challenge in further improving crop productivity in terms of grain yield and quality. Grain size is a complex trait controlled by multiple genes. Over the past few decades, genetic studies have identified various gene families involved in grain size development. The list of molecular mechanisms, and key regulators involved in grain size development is constantly expanding, making it difficult to understand the main regulators that play crucial roles in grain development. In this review, we focus on the major regulators of grain size, including G-protein signaling, the mitogen-activated protein kinase (MAPK) pathway, transcriptional regulation, the ubiquitin-proteasome degradation (UPD) pathway, and phytohormone signaling. These molecular mechanisms directly or indirectly regulate grain size. We provided a comprehensive understanding of the genes involved in these mechanisms and cross discussions about how these mechanisms are interlinked. This review serves as a valuable resource for understanding the molecular mechanisms that govern grain development and can aid in the development of molecular breeding strategies.","PeriodicalId":16813,"journal":{"name":"Journal of Plant Research","volume":" ","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143582315","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, this term includes studies in which cold storage was possible until further processing in a laboratory. Previous studies proposing onsite RNA extraction methods are limited to descriptions of RNA purity, quantity, and quality, and lack a thorough evaluation of transcriptome quality, and transcriptomic evaluations of RNA storage solutions in plants are, to our knowledge, only available for periods of less than a day. This issue is critical for studying plants in geographically difficult-to-access regions, where keeping the cold chain is unrealistic. In this study, the transcriptome of the non-model plant Helonias orientalis (order: Liliales) was evaluated before and after storage of the leaf tissue for one and fourteen days at 25 °C in RNAlater and TRIzol, respectively. Additionally, field-friendly protocols were similarly evaluated for onsite plant RNA extraction at ambient temperature with lightweight equipment that can run on a portable generator, including a guanidine isothiocyanate-free protocol that is compatible with the polyphenol-rich wild strawberry Fragaria vesca. The quality of the transcriptome assembly after 1-day storage and our optimized onsite methods had similar results to that of the state-of-the-art. However, in terms of differential expression analysis, onsite extraction methods performed better overall than the stored tissue samples. We expect that our onsite RNA extraction methods will provide valuable insights into the transcriptional regulation of plants in areas where research equipment is difficult to access.","PeriodicalId":16813,"journal":{"name":"Journal of Plant Research","volume":" ","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143573388","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
