In anther development, tapetal cells take part in complex processes, including endomitosis and apoptosis (programmed cell death). The tapetum provides many of the proteins, lipids, polysaccharides other molecules necessary for pollen development. Several transcription factors, DYT1, TDF1, AMS, MS188 MS1, have been reported to be essential development function Arabidopsis thaliana. Here, we present a detailed cytological analysis knockout mutants these genes, along with an situ RNA...
The tapetum plays a critical role during the development and maturation of microspores. DYSFUNCTIONAL TAPETUM 1 (DYT1) is essential for early tapetal development. Here, we determined that promoter region (-550 to -463 bp) contains indispensable cis-elements DYT1 expression. Although transcripts can be detected in both meiocytes cells, localization DYT1-GFP demonstrated strictly located cells microsporogenesis. Chromatin immunoprecipitation (ChIP) analysis revealed directly binds Defective...
Abstract The pollen wall, an essential structure for function, consists of two layers, inner intine and outer exine. latter is further divided into sexine nexine. Many genes involved in development have been reported, which the MYB transcription factor Male Sterile 188 (MS188) specifies Arabidopsis . However, nexine formation remains poorly understood. Here we report knockout TRANSPOSABLE ELEMENT SILENCING VIA AT-HOOK ( TEK) leads to absence TEK encodes AT-hook nuclear localized family...
Pollen development involves cell wall alteration of the male gametophyte, which is critical for plant fertility and requires MYB80 TRANSPOSABLE ELEMENT SILENCING VIA AT-HOOK (TEK) transcription factors in Arabidopsis (Arabidopsis thaliana). In this study, we found that myb80 tek double mutant exhibits a compromised degradation tetrad callose down-regulation five ANTHER-SPECIFIC PROTEIN 6 (A6) genes encoding β-1,3-glucanase. The quintuple A6 (a6-quint) exhibited delayed defective exine...
The timely release of mature pollen following anther dehiscence is essential for reproduction in flowering plants. AUXIN RESPONSE FACTOR17 (ARF17) plays a crucial role wall pattern formation, tapetum development, and auxin signal transduction anthers. Here, we showed that ARF17 also involved dehiscence. Arabidopsis (
Primexine deposition and plasma membrane undulation are the initial steps of pollen wall formation. However, little is known about genes involved in this important biological process. Here, we report a novel gene, NO PRIMEXINE AND PLASMA MEMBRANE UNDULATION (NPU), which functions early stage development Arabidopsis (Arabidopsis thaliana). Loss NPU function causes male sterility due to defect callose synthesis sporopollenin deposition, resulting disrupted npu mutants. Transmission electronic...
Summary During anther development the male gametophyte develops inside locule and tapetal cells provide all nutrients for its development. Magnesium Transporter 5 ( MGT ) is a member of family has dual functions Mg export import. Here, we show that mitosis intine formation are defective in mgt5 mutant. The transient expression GFP ‐ revealed localized plasma membrane. These findings suggest plays role importing from essential knockout ABORTED MICROSPORES AMS mutant being an regulator...
In Arabidopsis, the tapetum and microsporocytes are critical for pollen formation. Previous studies have shown that ARF17 is expressed in tetrads directly regulates tetrad wall synthesis direct target of miR160, promoterARF17::5mARF17 (5mARF17/WT) transgenic plants, which five silent mutations within miR160-complementary domain, sterile. Here, we found also tapetum, was defective arf17 mutants. Compared with mutants, 5mARF17/WT plants had abnormal tapetal cells but were less vacuolated...
Callose synthesis is critical for the formation of pollen wall pattern. CalS5 thought to be major synthethase callose wall. In Arabidopsis anther, ARF17 regulates expression and target miR160. Plants expressing miR160-resistant (35S:5mARF17 lines) with increased mRNA levels display male sterility. Here we report a zinc finger family gene, AtTTP, which involved in miR160 maturation Arabidopsis. AtTTP expressed microsporocytes, tetrads tapetal cells anther. Over-expression lines (AtTTP-OE...
Photoperiod/temperature-sensitive genic male sterility (P/TGMS) is widely applied for improving crop production. Previous investigations using the reversible sterile (rvms) mutant showed that slow development a general mechanism restoring fertility to P/TGMS lines in Arabidopsis. In this work, we isolated restorer of rvms-2 (res3), as was rescued by res3. Phenotype analysis and molecular cloning show point mutation UPEX1 l res3 leads delayed secretion callase A6 from tapetum locule tetrad...
Spinach (Spinacia oleracea L.), a globally consumed, nutrient-dense vegetable, contains diverse vitamins and minerals. However, elevated temperatures can constrain yield by interrupting leaf development photosynthetic efficiency. The mitochondrial transcription termination factor (mTERF) family, which regulates organellar gene expression, plays crucial roles in plant growth regulation. Thus, characterization of the spinach mTERF (SomTERF) family is critical for elucidating thermotolerance...
Abstract In Escherichia coli, transcription-translation coupling is mediated by NusG. Although chloroplasts are descendants of endosymbiotic prokaryotes, the mechanism underlying this in remains unclear. Here, we report through AtNusG chloroplasts. localized chloroplast nucleoids and closely associated with PEP complex interacting its essential component PAP9. It also comigrates ribosomes interacts their two components PRPS5 (uS5c) PRPS10 (uS10c). These data suggest that transcription...

Magnesium (Mg) is an abundant and important cation in cells. Plants rely on Mg transporters to take up from the soil, then transported anthers other organs. Here, we showed that MGT6+/− plants display reduced fertility, while mgt6 are fertile. MGT6 expressed anther at early stages. Pollen mitosis intine formation impaired aborted pollen grains (PGs) of plants, which similar defective observed mgt5 mgt9 mutants. These results suggest deficiency leads abortion plants. Our data organs including...
Parenting is an important factor affecting teenagers' gratitude, but few studies have deeply examined the impact of specific parenting behavior on gratitude. In this study, 357 high school students were tested by questionnaires to examine mechanism parental rejection adolescents' Results showed that (1) significantly and negatively predicted (2) after controlling for gender age, would indirectly gratitude through responsibility belief in a just world, respectively. These results suggested...
The COVID-19 pandemic has had severe mental health effects on adolescents. Psychological resilience is the ability to recover quickly from adversity and can help adolescents cope with stress dangers brought by better. Therefore, current study aimed explore developmental pattern of psychological in find sensitive period for intervention promote during pandemic. measured a total 559 using Connor-Davidson scale (CD-RISC) four grades: grade 7 8 junior high school, 10 11 school. It was found that...
