Seed germination and flowering initiation are both transitions responding to similar seasonal cues. This study shows that ABSCISIC ACID-INSENSITIVE MUTANT 5 (ABI5), a bZIP transcription factor, which plays an important role in the abscisic acid (ABA)-arrested seed germination, is robustly associated with floral transition Arabidopsis. Under long-day conditions, overexpression of ABI5 could delay through upregulating FLOWERING LOCUS C (FLC) expression. In contrast, ectopically overexpressing...
Plant water homeostasis is maintained by the phytohormone abscisic acid (ABA), which triggers stomatal pore closure in response to drought stress. We identified Arabidopsis small guanosine triphosphatase (GTPase) protein AtRac1 as a central component ABA-mediated process. ABA treatment induced inactivation of AtRac GTPases and disruption guard cell actin cytoskeleton. In contrast, ABA-insensitive mutant abi1-1, impaired closure, neither nor cytoskeleton was observed on treatment. These...
Abscisic acid (ABA) and cytokinin are key hormones controlling plant development. How ABA interplay to control the transition from a dry seed into young seedling remains elusive. Here we undertook gain-of-function genetic screen identify ABA-insensitive mutants during germination in Arabidopsis using an estradiol-inducible approach. In presence of estradiol, one these gim1 (germination insensitive mutant 1) exhibited elevated level that was attributed estradiol-induced expression AtIPT8...
Na+ and K+ homeostasis are crucial for plant growth development. Two HKT transporter/channel classes have been characterized that mediate either transport or when expressed in Xenopus laevis oocytes yeast. However, the Na+/K+ selectivities of K+-permeable transporters not yet studied cells. One study expressing 5′ untranslated region-modified constructs yeast has questioned relevance cation found heterologous systems selectivity predictions Therefore, here we analyze two highly homologous...
The brown planthopper, Nilaparvata lugens, is a pest that threatens rice (Oryza sativa) production worldwide. While feeding on plants, planthoppers secrete saliva, which plays crucial roles in nutrient ingestion and modulating plant defense responses, although the specific functions of salivary proteins remain largely unknown. We identified an N. lugens-secreted mucin-like protein (NlMLP) by transcriptome proteome analyses characterized its function, both planthopper plants. NlMLP highly...
Seed germination and innate immunity both have significant effects on plant life spans because they control the plant's entry into ecosystem provide defenses against various external stresses, respectively. Much ecological evidence has shown that seeds with high vigor are generally more tolerant of environmental stimuli in field than those low vigor. However, there is little genetic linking plants. Here, we show rice lectin receptor-like kinase OslecRK contributes to seed immunity. We...
Drought is one of the most severe environmental stresses affecting plant growth and limiting crop production. Although many genes involved in adaptation to drought stress have been disclosed, relevant molecular mechanisms are far from understood. This study describes an Arabidopsis gene, ASPG1 (ASPARTIC PROTEASE IN GUARD CELL 1), that may function avoidance through abscisic acid (ABA) signalling guard cells. Overexpression gene enhanced ABA sensitivity cells reduced water loss ectopically...
Drought stress is one of the disadvantageous environmental conditions for plant growth and reproduction. Given importance abscisic acid (ABA) to abiotic responses, identification novel components involved in ABA signalling transduction critical. In this study, we screened numerous Arabidopsis thaliana mutants by seed germination assay identified a mutant mlp43 (major latex protein-like 43) with decreased sensitivity germination. The was sensitive drought while MLP43-overexpressed transgenic...
BROWN PLANTHOPPER RESISTANCE14 (BPH14), the first planthopper resistance gene isolated via map-based cloning in rice (Oryza sativa), encodes a coiled-coil, nucleotide binding site, leucine-rich repeat (CC-NB-LRR) protein. Several and aphid genes encoding proteins with similar structures have recently been identified. Here, we analyzed functions of domains BPH14 to identify molecular mechanisms underpinning BPH14-mediated resistance. The CC or NB alone combination (CC-NB [CN]) conferred level...
Cytokinins in plants are crucial for numerous biological processes, including seed germination, cell division and differentiation, floral initiation adaptation to abiotic stresses. The salt stress can promote reactive oxygen species (ROS) production which highly toxic ultimately results oxidative stress. However, the correlation between endogenous cytokinin ROS homeostasis responding is poorly understood. In this study, we analyzed of overexpressing biosynthetic gene AtIPT8 (adenosine...
Characterization of the melatonin (MLT) biosynthesis pathway in plants is still limited. Additionally, a metabolomic analysis MLT challenge due to analyte structural and chemical diversity, low abundances, plant matrix complexities. Herein, sensitive liquid chromatography-mass spectrometry (LC-MS) method enabling simultaneous determination seven biosynthetic metabolites was developed. In proposed strategy, targeted metabolites, which included tryptophan (Trp), tryptamine (TAM),...
The brown planthopper (BPH), Nilaparvata lugens (Stål), is a phloem sap-feeding insect. During feeding on rice plants, BPH secretes salivary proteins with potential effector functions, which may play critical role in the plant-insect interactions. However, limited number of have been identified to date. Here, we sequenced gland transcriptomes five populations and subsequently established N. secretome consisting 1,140 protein-encoding genes. Secretome analysis revealed presence both conserved...
Melatonin is known to involve multiple physiological actions in plants. Herein, we found that exogenous melatonin inhibited the Arabidopsis seedling growth through elevated abscisic acid (ABA) levels, and ABA was ascribed upregulation of 9-cis-epoxycarotenoid dioxygenase genes (NCEDs) biosynthesis pathway. We also overexpression lines receptor gene PMTR1 (also as Cand2) yielded smaller seeds germinated slower than wild type, whereas PMTR1-knockout mutants produced larger faster type. During...
The brown planthopper (Nilaparvata lugens Stål, BPH) is one of the most economically significant pests rice. Bph30 gene has been successfully cloned and conferred rice with broad-spectrum resistance to BPH. However, molecular mechanisms by which enhances BPH remain poorly understood.Here, we conducted a transcriptomic metabolomic analysis Bph30-transgenic (BPH30T) BPH-susceptible Nipponbare plants elucidate response infestation.Transcriptomic analyses revealed that pathway plant hormone...
Summary Phospholipase C ( PLC ) is an enzyme that plays crucial roles in various signal transduction pathways mammalian cells. However, the role of plant development poorly understood. Here we report involvement 2 auxin‐mediated reproductive Arabidopsis. Disruption led to sterility, indicating a significant for development. Development both male and female gametophytes was severely perturbed plc2 mutants. Moreover, elevated auxin levels were observed floral tissues, suggesting infertility...
The APETALA1 (AP1)/FRUITFULL (FUL)-like transcription factor OsMADS18 plays diverse functions in rice development, but the underlying molecular mechanisms are far from fully understood. Here, we report that down-regulation of expression RNAi lines caused a delay seed germination and young seedling growth, whereas overexpression produced plants with fewer tillers. In targeted genome-edited mutants (osmads18-cas9), an increased number tillers, altered panicle size, reduced setting were...
