Genome-wide patterns of large-size presence/absence variants in sorghum

The presence/absence variants （PAVs） are a major source of genome structural variation and have profound effects on phenotypic and genomic variation in animals and humans. However, little is understood about PAVs in plant genomes. Our previous resequencing effort on three sorghum （Sorghum bicolour L.） genomes, each 12？ coverage, uncovered 5 364 PAVs. Here, we report a detailed characterization of 51 large-size （＆gt;30 kb） PAVs. These PAVs spanned a total size of 2.92 Mb of the sorghum genome containing 202 known and predicted genes, including 38 genes annotated to encode celldeath and stress response genes. The PAVs varied considerably for repeat sequences and mobile elements with DNA trans-posons as the major components. The frequency and distribution of these PAVs differed substantial y across 96＆amp;nbsp;sorghum inbred lines, and the low-and high frequency PAVs differed in their gene categories. This report shed new light on the occurrence and diversity of PAVs in sorghum genomes. Our research exemplifies a new perspective to explore genome structural variation for genetic improvement in plant breeding.     

Editorial

Plants--of the botanical kind--are not often mentioned in ＇The State of the Union＇ addresses by US Presidents, but when they are, it can have global impacts on plant biology research. In the 1990s, President Clinton ridiculed government support of research on ＇plant stress＇ in one of his addresses, confusing psychological stress with the devastating effects of drought, salinity, and other environmental stresses on agricultural productivity. A decade later, President Bush mentioned the S word （switchgrass） in connection with alternatives to petroleum, thereby encouraging the US Department of Energy to invest heavily in research to understand plant cell walls and to develop efficient processes to harness the sun＇s energy, which is stored on a massive scale in plant cell walls.     

Whole-genome sequencing in medicinal plants:current progress and prospect

Advancements in genomics have dramatically accelerated the research on medicinal plants,and the development of herbgenomics has promoted the “Project of 1K Medicinal Plant Genome” to decipher their genetic code.However,it is difficult to obtain their high-quality whole genomes because of the prevalence of polyploidy and/or high genomic heterozygosity.Whole genomes of 123 medicinal plants were published until September 2022.These published genome sequences were investigated in this review,coverin...     

Emerging directions in the study of the ecology and evolution of plant-animal mutualistic networks: a review

The study of mutualistic plant and animal networks is an emerging field of ecological research. We reviewed progress in this field over the past 30 years. While earlier studies mostly focused on network structure, stability, and biodiversity maintenance, recent studies have investigated the conservation implications of mutualistic networks, specifically the influence of invasive species and how networks respond to habitat loss. Current research has also focused on evolutionary questions including phylogenetic signal in networks, impact of networks on the coevolution of interacting partners, and network influences on the evolution of interacting species. We outline some directions for future research, particularly the evolution of specialization in mutualistic networks, and provide concrete recommendations for environmental managers.     

Azolla--a model organism for plant genomic studies

The aquatic ferns of the genus Azolla are nitrogen-fixing plants that have great potentials in agricultural production and environmental conservation. Azolla in many aspects is qualified to serve as a model organism for genomic studies because of its importance in agriculture, its unique position in plant evolution, its symbiotic relationship with the N2-fixing cyanobacterium, Anabaena azollae, and its moderate-sized genome. The goals of this genome project are not only to understand the biology of the Azolla genome to promote its applications in biological research and agriculture practice but also to gain critical insights about evolution of plant genomes. Together with the strategic and technical improvement as well as cost reduction of DNA sequencing, the deciphering of their genetic code is imminent.     

Sexual Plant Reproduction： a Fertile and Flourishing Field

Since the very beginning of plant science, sexual plant reproduction （SPR） has proved an attractive and enduring topic for generations of botanists. With the rapid development of modern technology, a significant acceleration has occurred in our understanding on the developmental mechanisms of plant reproductive processes, particularly the evolution of double fertilisation, signalling in pollen tube orientation, molecular characterisation of plant gametes, maternal to zygotic transitions and parental gene involvement in early embryogenesis. This is reflected not only by several recent high-ranking research papers, but also by the frequent conferences and workshops on these topics. These include the 2008 XXth International Congress on SPR in Brasilia and ＂Frontiers in SPR Ⅲ＂ in Tucson, as well as ＂Cell- Cell Communication in Plant Reproduction＂ held in 2009 in Bath. The continuing efforts from around the world indicate that SPR is still a fertile and flourishing field, with great expectations for the coming decade.     

Recent Progress on Rice Genetics in China

Through thousands of years of evolution and cultivation, tremendously rich genetic diversity has been accumulated in rice （Oryza sativa L.）, developing a large germplasm pool from which people can select varieties with morphologies of Interest and other important agronomic traits. With the development of modern genetics, scientists have paid more attention to the genetic value of these elite varieties and germplasms, and such rich rice resources provide a good foundation for genetic research in China. Approximately 100 000 accessions of radiation-, chemical- or insertion-induced mutagenesis have been generated since the 1980s, and great progress has been made on rice molecular genetics. So far at least 16 variant/mutant genes Including MOC1, BC1, SKC1, and Rfgenes have been isolated and characterized in China. These achievements greatly promote the research on functional genomics, understanding the mechanism of plant development and molecular design breeding of rice in China. Here we review the progress of three aspects of rice genetics in China： moving forward at the molecular level, genetic research on elite varieties and germplasms, and new gene screening and genetic analysis using mutants. The prospects of rice genetics are also discussed.

Molecular mechanisms of insect adaptation to plant defense： Lessons learned from a Bruchid beetle

Plants can accumulate, constitutively and/or after induction, a wide variety of defense compounds in their tissues that confer resistance to herbivorous insects. The naturally occurring plant resistance gene pool can serve as an arsenal in pest management via transgenic approaches. As insect-plant interaction research rapidly advances, it has gradually become clear that the effects of plant defense compounds are determined not only by their toxicity toward target sites, but also by how insects respond to the challenge. Insect digestive tracts are not passive targets of plant defense, but often can adapt to dietary challenge and successfully deal with various plant toxins and anti-metabolites. This adaptive response has posed an obstacle to biotechnology-based pest control approaches, which underscores the importance of understanding insect adaptive mechanisms. Molecular studies on the impact of protease inhibitors on insect digestion have contributed significantly to our understanding of insect adaptation to plant defense. This review will focus on exposing how the insect responds to protease inhibitors by both qualitative and quantitative remodeling of their digestive proteases using the cowpea bruchid-soybean cysteine protease inhibitor N system.     

The plant cell wall: Biosynthesis,construction, and functions

The plant cell wall is composed of multiple biopolymers, representing one of the most complex structural networks in nature. Hundreds of genes are involved in building such a natural masterpiece. However, the plant cell wall is the least understood cellular structure in plants. Due to great progress in plant functional genomics,manyachievementshavebeenmadein uncovering cell wall biosynthesis, assembly, and architecture, as well as cell wall regulation and signaling. Such information has significantly advanced our understanding of the roles of the cell wall in many biological and physiological processes and has enhanced our utilization of cell wall materials. The use of cutting-edge technologies such as single-molecule imaging,nuclear magnetic resonance spectroscopy, and atomic force microscopy has provided much insight into the plant cell wall as an intricate nanoscale network, opening up unprecedented possibilities for cell wall research. In this review,we summarize the major advances made in understanding the cell wall in this era of functional genomics, including the latest findings on the biosynthesis, construction, and functions of the cell wall.
