Summary: Research has shown that rice euANT/PLT genes exhibit divergent temporal expression patterns during early branching stages, with spatial localization in meristems for two of these genes. Furthermore, functional analysis of rice ANT-related genes using genome editing revealed their significance in regulating panicle architecture through axillary meristem establishment and fate transition. The paralogous euANT/PLT genes have partially diversified in functions and act in regulating the branching of the rice panicle.

Summary: In this study, it was found that maize ear inflorescences with loss-of-function gif1 mutations exhibited highly branched structures, producing more floral branches. GIF1 was shown to interact with multiple GRFs, chromatin-remodeling proteins, and hormone biosynthesis-related proteins. It was also found that GIF1 directly regulated key genes involved in meristem determinacy and CLV3/ESR4a signaling in the ear inflorescence of maize.

Summary: Lateral branches such as shoot and panicle are crucial for rice yield improvement, with cytokinin playing a significant role in promoting rice lateral branching. The study identified the RLB gene, which regulates cytokinin homeostasis by repressing the transcription of the OsCKX4 gene, leading to enhanced rice lateral branching. This finding provides insights into cytokinin balance, lateral branching mechanisms in plants, and potential target genes for rice genetic enhancement.

Summary: In barley, the size of the inflorescence meristem (IM) is negatively correlated with yield traits, and the loss-of-function mutants of the FASCIATED EAR (FEA) genes exhibit enlarged IM size, shortened spikes, and reduced spikelet number, leading to reduced grain yield.

Summary: Through comparative morphology and molecular genetic experiments, this study investigated the gene structure and function of mc2 in Brassica juncea and Arabidopsis. It was found that mc2 is a ortholog of CLV1, BjA7.CLV1, and its deletion in the cis-regulatory region in the promoter led to the formation of trilocular silique. The results suggest a conserved pleiotropic role of BjCLV1 in shoot meristem and CMM development, with a specific cis-regulatory region involved in its expression.

Summary: The study assessed seven pairs of NILs targeting four QTL on wheat chromosome arms and found significant differences in PH and other traits among NIL pairs. SNP and candidate gene information can be useful for marker-assisted selection in breeding programs, and the four targeted QTL are crucial genomic regions controlling agronomic traits.

Summary: This study identified key genetic factors associated with seed yield, plant height, protein yield, and thousand-seed weight in early-maturing soybean, with some loci showing pleiotropic effects on multiple traits. The E1 and E3 maturity genes, as well as the Dt2 stem growth habit gene, were highlighted as likely candidates underlying these QTL, with implications for marker-assisted selection.

Summary: This study examined the effects of phytic acid concentration in black and white rice seeds on seedling vigor. The results showed that high phytic acid concentration in black rice seeds enhanced seedling growth and phosphorus uptake. Low phytic acid concentration in black rice seeds reduced seedling vigor in phosphorus-deficient soils. These findings provide important guidance for black rice cultivation.

Summary: The spikelet indeterminacy and supernumerary spikelet phenotypes in the barley multiflorus2.b mutant exhibit polygenic inheritance. Major QTLs for these phenotypes were identified on chromosomes 2H and 6H. The co-location of QTLs for lateral spikelet indeterminacy and central spikelet supernumerary phenotypes suggests a potential regulation by a single genetic factor. Further research into the genes underlying these QTLs will contribute to understanding yield formation in small grain cereals.

Summary: In the late 1980s, geneticists began using chemical mutagens to induce random mutations in seeds and screen for plants with defective flower development. The study conducted at Caltech and Monash University focused on Arabidopsis thaliana mutants and identified genes controlling flower organ identity, meristem identity, organ development, and meristem properties. These findings have contributed to our understanding of transcriptional control, signaling, and the role of auxin in initiating flower development.

Summary: In this study, eight candidate genes were selected and validated using three statistical algorithms to identify suitable genes for diurnal expression data normalization in quinoa. The results showed that isocitrate dehydrogenase enzyme (IDH-A) and polypyrimidine tract-binding protein (PTB) were identified as appropriate reference genes. Validating these reference genes will improve the accuracy of RT-qPCR data normalization and facilitate gene expression studies in quinoa.

Summary: The response to photoperiod is crucial for plant growth and adaptation. Quinoa, a short-day plant, also needs to adapt to long-day conditions. This study identified differences in photoperiod sensitivity among quinoa accessions and highlighted the role of flowering time genes in adaptation to different day-length conditions, providing valuable assets for quinoa breeding.
