Summary: The quantity and composition of grain storage proteins (GSPs) play a crucial role in determining the value of wheat flour. The expression of GSP genes is regulated by a complex network of DNA-protein and protein-protein interactions. In this study, the wheat ortholog of the transcription factor SAD, named TaSAD, was identified and its binding to GSP gene promoters was investigated. The results showed that TaSAD and another transcription factor WPBF activate GSP gene expression, and their co-bombardment with Storage Protein Activator (SPA) had an additive effect. These findings provide important insights into the regulation of GSP gene expression in wheat.

Summary: RNA sequencing analysis and quantitative real-time PCR were used to compare the gene expression profiles of sh2 mutant and wild-type maize. The results suggest that the sh2 gene mutation affects the transcript and protein levels of zein genes, indicating a potential regulation of zein production through transcriptional and post-transcriptional mechanisms.

Summary: TaPGS1, a transcription factor belonging to the basic helix-loop-helix family, is specifically expressed during seed development in wheat. Overexpression of TaPGS1 increases grain weight and size, as well as carbohydrate and total protein levels. TaPGS1 regulates the expression of PLATZ transcription factor genes and plays a critical role in cereal grain development.

Summary: The study reveals that ZmABI19 functions as a key transcription factor in regulating maize grain filling, with mutations affecting endosperm and embryo development, resulting in opaque and reduced kernels. ZmABI19 directly regulates multiple important grain filling TFs and plant phytohormone signal transduction, highlighting its role in coordinating early endosperm and embryo development.

Summary: The developing maize endosperm has evolved mechanisms to acclimate to hypoxia, including an interconnected void space that provides superior oxygen supply and high diffusion resistance within the endosperm. Manipulation of oxygen supply induced shifts in gene expression and metabolic pathways, resulting in enhanced kernel development. This study provides evidence for the establishment and acclimation to hypoxia in the maize endosperm.

Summary: In this study, a salt-tolerant maize mutant ZmWRKY20 was identified through screening of ethyl methanesulfonate-induced mutants. Further analysis revealed that the mutant exhibited higher resistance to wilting and lower reactive oxygen species levels compared to the inbred line B73. ZmWRKY20 regulates the response of maize to salt stress through interactions with other transcription factors and reprogramming of genes involved in defense and oxidation-reduction responses. This study enhances our understanding of the mechanisms underlying maize responses to salt stress.

Summary: The CRISPR/Cas9 genome editing technique has been established in maize using a seed fluorescence reporter system, allowing for the successful generation of desired mutants or mutant libraries. This approach may be particularly valuable for scenarios with low transformation frequency and has the potential to be expanded to other important monocot seed crops.

Summary: The plant membrane-trafficking system is essential for cellular functions and responds to various cues. This study systematically identified and studied the functions of membrane-trafficking genes in maize. The genes showed diverse expression patterns, with some being associated with protein biosynthesis and defense-related genes. Additionally, membrane-trafficking genes with selection signals during maize domestication and improvement were identified.

Summary: This study comprehensively analyzed the changes in the expression patterns of plant hormone metabolism genes and the levels of their bioactive forms during barley seed development. The results showed that the levels of plant hormones were generally high in the endosperm and embryo tissues at the early stage of seed filling, but decreased during seed filling, except for ABA. The level of ABA in the embryo increased during seed filling and peaked at physiological maturity, while the endospermic ABA remained stable during seed filling. After physiological maturity, most hormones in both tissues showed low levels, except for higher levels of jasmonoyl-isoleucine and SA detected at late stage.

Summary: Novel diversity in tomato Cyc-B gene can be utilized to modulate beta-carotene levels through marker-assisted breeding approaches. Different alleles of Cyc-B gene were found in high beta-carotene tomato varieties, offering potential for trait modulation in tomato breeding programs. Phylogenetic analysis suggested that high beta-carotene alleles in tomato were likely derived from wild species, and SNP markers were identified as major contributors to elevated beta-carotene levels.
