Seed is the most important reproductive organ in plant. Since its first emergence approximately 370 million years ago, seed plant had overwhelming advantage to non-seed plants in reproduction, spreading and colonization in terrestrial land. Beside its essential function in the sexual reproduction of plants, seed is the most economically important agricultural product, offering necessity food for human and wildlife, nutritious feed for livestock. Seeds and grains also provide massive amount of raw materials for manufactured goods, such as coffee, starch, and oil. Seeds also play a pivotal role in development of fruits which supplement significant portion of food and nutrition for human and wildlife. As the climate change intensifies, sustainable production of seed-based food for projected nine billion people by midcentury become more challenging. Another dimension of challenges is that a rapidly increasing more affluent populations, such as in China, will seek more nutritious and healthy seed-based food and proteins that require everincreasing seed-based feed for animals. Because of their essential roles, human has started to select seeds in agrarian age by keeping larger seeds (grains and fruits). Modern seed research probably can be traced back to Mendel’s genetic study on pea seed traits. In the last century, seed research has been primarily focused on endosperm (monocots) and embryo (dicots), the main storage compartments, and their dormancy and germination processes, or reproductive processes leading to the seed formation. With enormous research, agronomic crop yield has increased drastically, as shown in rice and corns, for examples. Recent unprecedented advances in multiple omics tools in conjunction with modern genetic, molecular, physiological, biochemical, and biotechnological approaches have pushed seed research to another wave of increment of crop yield, quality in an environment-friendly manner. This is evident with the publication increase (Fig. 1). However, in contrast with active basic seed research, few academic journals have focused on publishing seed biology research, and the current seed-focused journals are largely application-centric. This calls for a professional journal with focus on the basic seed biology, and to fill this gap, I am pleased to announce the launching Seed Biology. This journal aims to become a rigorously peer-reviewed, flagship international journal, covering research on the following, but not limited to, the evolution of seeds, processes leading to seed formation such as sporogenesis and gametogenesis, pollination and fertilization, apomixis and artificial seeds, regulation and manipulation of seed yield, nutrition and health related quality of endosperm, cotyledons, and the seed coat, seed dormancy and germination, seed interactions with environment and other microbes, roles of seeds in fruit developments, by using all cutting age research approaches, including omics, genetics, biotechnology, and genome e

Seed germination relies on preserving mRNA integrity in dry seeds. However, the quality of mRNA in aged wheat seeds is not well understood. Here, we investigated 20 wheat varieties for seed longevity using controlled deterioration treatment (CDT) and identified that Chinese Spring seeds exhibit moderate longevity. We observed correlations between seed viability and RNA integrity in the aleurone and embryo cells after aging-treatment. Nanopore sequencing of whole seeds from natural aging treatment (NAT) and CDT for 25 days identified 3,083 full-length transcripts. We performed RNA-seq transcriptome profiling to classify the tissue origin of these transcripts under eight aging treatments, revealing the presence of 2,064 overlapping long-lived mRNAs (LLRs) in the seed embryo and 2,130 in the aleurone layers. These LLRs corresponded to genes with detectable transcription levels and at least one full-length transcript in their coding sequence. Notably, degradation percentages of these mRNAs varied among seeds of different wheat varieties with similar ages. We predicted 21 most stable LLRs with high GC% content and short coding sequence length, among which only one LLR was seed-specifically expressed and belonged to the late-embryogenesis-abundant (LEA) protein family. RT-PCR confirmed the expression of the seven LLR fragments in the aleurone layer and embryo of Chinese Spring seeds. We found three of the most stable LLRs (LLR13, LLR15, and LLR20) identified in Chinese Spring were more stable in high longevity varieties than in short longevity varieties after aging, indicating their potential roles in seed longevity and germination.

Rice ( Oryza sativa L.) is not only a model monocotyledon plant, but also an important cereal seed crop. Improvements in seed-related traits is the key to obtaining high grain yield and quality, therefore attracting attention from both scientists and crop breeders. In higher plants, brassinosteroid (BR), a major growth-promoting hormone, plays an important role in regulating numerous agronomic traits associated with both vegetative and reproductive growth, thereby presenting huge application potential. Here, we review recent progress into BR regulation in rice seed biology. Both BR biosynthesis and signaling have been shown to regulate grain size, grain filling, grain number, seed germination and biosynthesis of seed components. Thus, considering the pleiotropic effects of BR, strategies aimed at genetic modulation of the BR pathway have been proposed to improve seed-related traits in rice, and therefore, enhance both yield and quality. This review not only strengthens our understanding of the underlying mechanism and regulatory network of BR-regulated key agronomic traits in rice, but also facilitates the future application of BR in rice breeding programs.

Successful pollen formation is essential for plant reproduction. During anther development, microspore mother cells undergo meiosis to form tetrads. After being released from the tetrad, microspores develop into mature pollen. The tapetum is the innermost layer of anther somatic cells and forms a locule to provide nutrition, enzymes and pollen wall materials for microspore development. Based on the male sterile phenotype, many genes important for tapetum and pollen development have been cloned. In this review, we highlight the genetic pathway of DYT1-TDF1-AMS-MS188-MS1 which acts in tapetal development in Arabidopsis . We also compared this genetic pathway in different species such as Arabidopsis , rice and maize. Based on this pathway, we review recent findings and insights into the contribution of the tapetum to pollen formation at the molecular level. 1) Tapetum provides nutrition for microspore development. 2) Tapetum provides enzymes to dissolve pectin and callose to release microspores from tetrads. 3) Tapetum synthesizes precursors for pollen wall formation via different molecular pathways. 4) Tapetum provides precursors for pollen coat formation. 5) Tapetum provides small RNAs to regulate genic methylation in the germline cells. The contributions of sporophytic tapetum to pollen formation.
