Soybean, the fourth most important crop in the world, uniquely serves as a source of both plant oil and plant protein for the world's food and animal feed. Although soybean production has increased approximately 13-fold over the past 60 years, the continually growing global population necessitates further increases in soybean production. In the past, especially in the last decade, significant progress has been made in both functional genomics and molecular breeding.

Legumes have the capability to form nodules that facilitate symbiotic nitrogen fixation (SNF) with rhizobia. Given the substantial energy consumption during the process of SNF, legumes need to optimize nodule number in response to everchanging environmental scenarios. The TGACG BINDING FACTOR1/4 (TGA1/4) are key players in the basal immune response of plants.

Transcription, as a crucial step in the transmission of genetic information, is completed by DNA-dependent RNA polymerase. In eukaryotes, the transcription of protein-coding genes is completed by RNA polymerase II (Pol II). A distinctive feature of Pol II is the carboxy-terminal domain (CTD) of its largest subunit, RPB1, which is composed of a series of heptapeptide repeats that play a vital role in transcription.

Post-Flowering Photoperiod Sensitivity of Soybean in Pod-Setting Responses.

Biology (Basel)

October 2024

Guangdong Key Laboratory of Plant Adaptation and Molecular Design, School of Life Sciences, Guangzhou University, Guangzhou 510006, China.

Article Synopsis
  • - The study examines how the photoperiod influences soybean development, particularly focusing on flowering time and its effects on pod formation.
  • - Findings reveal that long-day conditions prolong the flowering-to-pod formation interval and result in flower drop, while short-day conditions affect pistil morphology, aiding pollen interaction and pod timing.
  • - The research also identifies photoperiod-insensitive mutants that show no change in pod formation timing, suggesting that hormones, ROS signals, and sucrose application may play roles in flower drop.

Although individual genomic structural variants (SVs) are known to influence gene expression and trait variation, the extent and scale of SV impact across a species remain unknown. In the present study, we constructed a reference library of 334,461 SVs from genome assemblies of 16 representative morphotypes of neopolyploid Brassica napus accessions and detected 258,865 SVs in 2,105 resequenced genomes. Coupling with 5 tissue population transcriptomes, we uncovered 285,976 SV-expression quantitative trait loci (eQTLs) that associate with altered expression of 73,580 genes.

Legumes, characterized by their ability to form symbiotic relationships with nitrogen-fixing bacteria, play crucial roles in agriculture, ecology and human nutrition. Phosphatidylethanolamine-binding proteins (PEBPs) are the key genetic players that contribute to the diverse biological functions of legumes. In this review, we summarize the current understanding of important roles of PEBP genes in legumes, including flowering, inflorescence architecture, seed development and nodulation.

Symbiotic nitrogen fixation (SNF) in legume-rhizobia serves as a sustainable source of nitrogen (N) in agriculture. However, the addition of inorganic N fertilizers significantly inhibits SNF, and the underlying mechanisms remain not-well understood. Here, we report that inorganic N disrupts iron (Fe) homeostasis in soybean nodules, leading to a decrease in SNF efficiency.

AP1c and SOC1 Form a Regulatory Feedback Loop to Regulate Flowering Time in Soybean.

Plant Cell Environ

October 2024

Guangdong Key Laboratory of Plant Adaptation and Molecular Design, Guangzhou Key Laboratory of Crop Gene Editing, Innovative Center of Molecular Genetics and Evolution, School of Life Sciences, Guangzhou University, Guangzhou, China.

Flowering time is a key agronomic trait that directly affects soybean yield. Both APETALA1 (AP1) and SUPPRESSOR OF OVEREXPRESSION OF CO 1 (SOC1) regulate flowering time in soybean, but their genetic and regulatory relationships have not been clarified. Here, we report that AP1c physically interacted with two SOC1 proteins, SOC1a and SOC1b, and that these SOC1s upregulated the expression of AP1c, promoting flowering.

Control of DNA demethylation by superoxide anion in plant stem cells.

Nat Chem Biol

Ministry of Education Key Laboratory for Cellular Dynamics, Chinese Academy of Sciences Center for Excellence in Molecular Plant Sciences, School of Life Sciences, Division of Life Sciences and Medicine, University of Science and Technology of China, Hefei, China.

Superoxide anion is thought to be a natural by-product with strong oxidizing ability in all living organisms and was recently found to accumulate in plant meristems to maintain stem cells in the shoot and undifferentiated meristematic cells in the root. Here we show that the DNA demethylase repressor of silencing 1 (ROS1) is one of the direct targets of superoxide in stem cells. The Fe-S clusters in ROS1 are oxidized by superoxide to activate its DNA glycosylase/lyase activity.

The Biosynthesis Process of Small RNA and Its Pivotal Roles in Plant Development.

Int J Mol Sci

July 2024

Guangdong Key Laboratory of Plant Adaptation and Molecular Design, Guangzhou Key Laboratory of Crop Gene Editing, Innovative Center of Molecular Genetics and Evolution, School of Life Sciences, Guangzhou University, Guangzhou 510006, China.

In the realm of plant biology, small RNAs (sRNAs) are imperative in the orchestration of gene expression, playing pivotal roles across a spectrum of developmental sequences and responses to environmental stressors. The biosynthetic cascade of sRNAs is characterized by an elaborate network of enzymatic pathways that meticulously process double-stranded RNA (dsRNA) precursors into sRNA molecules, typically 20 to 30 nucleotides in length. These sRNAs, chiefly microRNAs (miRNAs) and small interfering RNAs (siRNAs), are integral in guiding the RNA-induced silencing complex (RISC) to selectively target messenger RNAs (mRNAs) for post-transcriptional modulation.

Background: Heterosis has successfully enhanced maize productivity and quality. Although significant progress has been made in delineating the genetic basis of heterosis, the molecular mechanisms underlying its genetic components remain less explored. Allele-specific expression (ASE), the imbalanced expression between two parental alleles in hybrids, is increasingly being recognized as a factor contributing to heterosis.
