This is an authoritative book that acts as a guide to understanding maize kernel development. Written by a team of experts, it covers topics spanning pre- and post-fertilization events, embryo and endosperm development, grain filling and maturation, and factors influencing crop yield. It explores the significance of maize and other cereal grains, existing hypotheses and research, and important gaps in our knowledge and how we might fill them. This is a valuable resource for researchers of maize and other cereals, and anyone working on basic or applied science in the fields of seed development, plant genetics, and crop physiology.

The maize kernel is at the heart of research efforts geared to elucidate the molecular mechanisms governing its development and the accumulation of oil and starch in its two major compartments, embryo and endosperm. Here, we present the molecular and phenotypic characterisation of two maize kernel mutants, the embryo-specific PPR8522 and the miniature PPR2263 mutant. Despite dissimilar phenotypes both mutations concerned genes coding for pentatricopeptide repeat (PPR) proteins predicted to act in organellar RNA processing. The gene responsible for the embryo-lethal phenotype of PPR8522 was identified by transposon tagging and confirmed by fine mapping. PPR8522 contains 10 PPR motifs, is targeted to plastids and required for the transcription of nearly all plastid-encoded genes. Mutant embryos deviate as early as the 3-cell stage from normal development but can be rescued in vitro in certain genetic backgrounds. Rescued mutant plantlets have an albino lethal phenotype due to a substantial cellular desorganisation of their plastids including a total lack of thylakoid stacks. The mutation responsible for the miniature kernel phenotype of PPR2263 was identified by a novel cDNA transposon display technique. The cloning was confirmed by transgenic complementation via Agrobacterium-mediated maize transformation. PPR2263 contains 10 PPR motifs, a mitochondrial-targeting sequence and a DYW domain, suggesting a role in organellar RNA editing. Mutant plants hardly ever reach sexual maturity and are characterised by slow growth.

Two different aspects of maize kernel development are investigated. First, transcriptomic analyses of the landmark stages in embryo development were performed using laser microdissection and RNA-sequencing to investigate the ontogeny of shoot apical meristem (SAM). The SAM gives rise to all above ground vegetative tissues and forms during embryogenesis. To date this is the first study conducted to survey the maize SAM transcriptome when it forms during embryo development. Transcriptomic analyses of a developing embryo before a SAM forms, after a SAM is established, and when the SAM is initiating a foliar leaf reveals the following: (1) how a meristem is formed; (2) how a newly formed meristem differs from a mature meristem that is initiating foliar leaves; (3) the differences between the first three lateral organs (the scutellum, the coleoptile, and foliar leaf) elaborated during embryogenesis; (4) what distinguishes initiation of juvenile from an adult leaf; and (5) the differences between the SAM initiating a foliar leaf and a lateral meristem initiating a husk leaf. Second, embryo and endosperm development is investigated using the defective kernel mutant discolored1 (dsc1). Detailed phenotypic analyses of dsc1 mutant kernels reveal that DSC1 encodes a protein that is required to maintain the differentiation of both the embryo and the endosperm during kernel development. The DSC1 gene encodes an ADP-RIBOSYLATION FACTOR-GTPASE ACTIVATING PROTEIN (ARF-GAP) that colocalizes with the trans-Golgi network/early endosomes and the plasma membrane in transient expression assays in N. benthamiana leaves. DSC1 functions in endomembrane trafficking and the cargo that it transports is required for maintaining differentiated embryo and endosperm structures during kernel development.
