Summary Flowering time is a key agronomic trait determining environmental adaptation and yield potential of crops. The regulatory mechanisms flowering in maize still remain rudimentary. In this study, we combine expressional, genetic, molecular studies to identify two homologous SQUAMOSA PROMOTER BINDING PROTEIN‐LIKE (SPL) transcription factors ZmSPL13 ZmSPL29 as positive regulators juvenile‐to‐adult vegetative transition floral maize. We show that both are preferentially expressed leaf...
Increasing planting density has been adopted as an effective means to increase maize (Zea mays) yield. Competition for light from neighbors can trigger plant shade avoidance syndrome, which includes accelerated flowering. However, the regulatory networks of inflorescence development in response high-density remain poorly understood. In this study, we showed that shade-mimicking treatments cause precocious tassels and ears. Comparative transcriptome profiling analyses revealed enrichment...
Mutation breeding is a significant means of increasing efficiency and accelerating process. In present study, we explored new method for mutations inducing in rice (Oryza sativa L.) by using direct current electrophoresis bath (DCEB). The results showed that 20 mM NaCl solution the optimal buffer, mortality seeds followed an upward trend with voltage processing time DCEB. By exploring mutagenic effects γ-irradiation DCEB on seed vigor physiological damages, found damages induced were...
Although several regulators associated with purple traits in rice have been identified, the genetic basis of sheath remains unclear. In present study, F2-1 and F2-2 populations were constructed using (H93S) green (R1173 YHSM), respectively. order to identify QTL loci sheaths, BSA analyses performed on two F2 populations. A crucial for was tentatively named qPLSr6, located 4.61 Mb 6.03 region chromosome 6. Combined expression pattern analysis candidate genes, LOC_Os06g10350 (OsC1PLSr)...
Summary Maize silk is a specialized type of stigma, covered with numerous papillae for pollen grain capture. However, the developmental process stigmatic and underlying regulatory mechanisms have remained largely unknown. Here, we combined cytological, genetic molecular studies to demonstrate that three homologous genes ZmSPL10 , ZmSPL14 ZmSPL26 play central role in promoting papilla formation maize. We show their triple knockout mutants are nearly complete lack papilla, resulting severe...
