Establishment of polarity in these lateral organs is one of the most critical events for their morphogenesis. However, the molecular mechanisms regarding this in rice remain unclear. Here, we isolated two allelic mutants named <i>degenerated hull 2-1</i> and <i>degenerated hull 2-2</i> (<i>dh2-1</i> and <i>dh2-2</i>) in rice, exhibiting abaxially rolled leaves and rod-shaped lemmas. <i>DH2</i> encoded the relatively conservative ARGONAUT 7 (AGO7) protein in plants and expressed in the lateral organs including leaf and floral organs. In addition, the overexpression lines of <i>DH2</i> showed adaxially rolled leaves. Next, it was proved that <i>DH2</i> was involved in the synthesis of <i>tasiR-ARFs</i>, the expression level of which was decreased sharply in lateral organs of <i>dh2</i> mutants. Then, it was found that the expression of <i>OsARF2, OsARF3, OsARF14</i>, and <i>OsARF15</i>, the potential targets of <i>tasiR-ARFs</i>, was increased in lateral organs of <i>dh2</i> mutants. However, it was not expected that the results of <i>in situ</i> hybridization showed that the four <i>ARF</i> genes were not expressed in WT lemma, whereas they were all ectopically expressed in rod-shaped lemma in <i>dh2</i> mutants. Meanwhile, <i>tasiR-ARFs</i> were expressed in the whole lemma but not in the abaxial side. This means that there was no opposite expression of <i>tasiR-ARFs</i> and <i>ARFs</i> in the adaxial-abaxial of lemma. Therefore, according to our data, we believe that the pathway of OsAGO7-tasiR-ARFs in rice was more likely involved in the development of the whole lemma, not only the abaxial side, by restricting the ectopic expression of <i>OsARFs</i> in the whole lemma, which was different from that in the lateral organs of Arabidopsis.</p>","PeriodicalId":12632,"journal":{"name":"Frontiers in Plant Science","volume":"15 ","pages":"1534038"},"PeriodicalIF":4.1,"publicationDate":"2025-01-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11808002/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143390593","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The slow growth of this species during the seedling stage exacerbates these problems. Therefore, it is important to realize the regulating effects of N and P proportioning fertilization on seedling growth to enhance nutrient-use efficiency. In this study, variations in morphological, physiological, and biochemical characteristics of seedlings were analyzed under nine treatments of NP proportioning in an open nursery using a regression design. Growth in height and basal diameter increased and showed an approximate tendency in all treatments. The maximum biomass accumulation was observed at 480 d after treatment in roots of T5 (14.714 g) (application N 0.4 g·per^-1 and P 3 g·per^-1), stems of T5 (12.654 g), leaves of T9 (24.261 g) (application N 0.8 g·per^-1 and P 6 g·per^-1), aboveground parts of T9 (35.402 g) and individuals of T5 (49 g). The total chlorophyll content peaked in the leaves at 120 d and was correlated with the peak levels of N, P, and K in leaves. The content and reserves of nutrient elements in the organs of seedlings subjected to NP proportioning were significantly higher than those in unfertilized seedlings. Analysis of nutrient utilization efficiency revealed that T5 demonstrated superior seedling growth performance. Appropriate fertilization dosage of N and P for <i>P. yunnanensis</i> seedlings in this study was 0.32 g·per^-1-0.58 g·per^-1 and 3.02 g·per^-1-4.95 g·per^-1 respectively, using path analysis and regression equation. Transcriptomic sequencing revealed that there were 2,301 DEGs between T5 and T1 (control), which were involved in the uptake and assimilation of nutrients, biosynthesis of phytohormones and secondary metabolites, and photosynthesis. Additionally, the abundance of genes involved in cell division and proliferation, cellulose biosynthesis, and cell wall extension were dramatically upregulated, which potentially correlated with enhanced seedling growth.

Our results revealed that PMMoV induced more pronounced mosaic symptoms and higher viral accumulation levels in the susceptible line 21C241 compared to the resistant line 21C385.

This study focuses on the physiological response of duckweed (<i>Lemna mino</i>r) exposed to PFOA so as to determine phytotoxicity and the potential of this aquatic species to remove PFOA from the environment. A time-dependent phytotoxicity assay showed that exposure to 0.1 µg/L PFOA for 14 days resulted in the loss of chlorophyll pigment and 15-25% more chlorosis than in controls. Although exposure to PFOA for seven days resulted in chlorosis, no significant impact on physiological parameters such as photosynthetic pigment or anthocyanin content were detected. The analysis of cellular size on day zero and seven of the experiment showed that the control group showed significantly larger cell size after seven days (213 ± 6.5 µm²) compared with the day zero group (186 ± 18 µm²), while the size of the PFOA exposed group (198 ± 13 µm²) did not change significantly after seven days compared with the day zero group.

However, accurate authentication of these medicinal species and their phylogenetic relationships with related taxa remains unresolved.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods: &lt;/strong&gt;To identify simple sequence repeats (SSRs) and divergence hotspot regions appropriate for future authentication studies, as well as to infer the phylogenetic relationships among &lt;i&gt;Asparagus&lt;/i&gt; species, we employed a plastid genome (plastome) dataset consisting of 25 &lt;i&gt;Asparagus&lt;/i&gt; species (21 newly sequenced and four retrieved from GenBank), encompassing 12 Chinese medicinal species, for comparative and phylogenetic analyses.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;All &lt;i&gt;Asparagus&lt;/i&gt; plastomes displayed a typical quadripartite structure with sizes ranging from 155,948 bp to 157,128 bp and harbored 114 unique genes (80 protein-coding genes, 30 tRNA genes, and four rRNA genes). IRscope and Mauve analyses indicated minimal structural variation among &lt;i&gt;Asparagus&lt;/i&gt; plastomes. We detected between 79 to 95 SSRs across the plastomes; most were located in the large single-copy (LSC) region and primarily consisted of mono-nucleotide repeat sequences (especially A and T repeats). The genus displayed mono-, di-, tri-, tetra-, penta-, and hexa-nucleotide repeats, but with variations in types and numbers among different species.
