Plant architecture is a popular research topic because plants with different growth habits that may generate economic or ornamental value are in great demand by orchards and nurseries. However, the molecular basis of the architecture of woody perennial plants is poorly understood due to the complexity of the phenotypic and regulatory relationships. Here, transcriptional profiling of dwarf and non-dwarf crapemyrtles was performed, and potential target genes were identified based on the phenotype, histology and phytohormone metabolite levels. An integrated analysis demonstrated that the internode length was explained mainly by cell number and secondarily by cell length and revealed important hormones in regulatory pathway of Lagerstroemia architecture. Differentially expressed genes (DEGs) involved in phytohormone pathways and cellular patterning regulation were analysed, and the regulatory relationships between these parameters were evaluated at the transcriptional level. Exogenous indole-3-acetic acid (IAA) and gibberellin A4 (GA4) treatments further indicated the pivotal role of auxin in cell division within the shoot apical meristem (SAM) and suggested an interaction between auxin and GA4 in regulating the internode length of Lagerstroemia. These results provide insights for further functional genomic studies on the regulatory mechanisms underlying Lagerstroemia plant architecture and may improve the efficiency of woody plant molecular breeding.

“…In early study, the inheritance methods of K + utilization efficiency have been similarly considered as additive-dominance-epistasis polygene genetic model (Gabelman and Loughman 1987). In our study, the major gene heritability of BC1P1, BC1P2 and F2 populations were 0.88%, 50.4% and 69.45%, respectively, indicating that the inheritance method of each populations was diverse due to the genetic background of the parents' traits (Ye et al 2017). The phenotype characters were influenced by close integration between genetic effect and environmental influence.…”

Potassium (K) is one of the essential nutrients for tomato. Potassium deficiency will limit tomato growth and yield. So improving the low-K+ (LK) resistance of tomato seems important. Two tomato cultivars (JZ18 and JZ34) differing in LK resistance were obtained to analyze the plant demonstration difference under LK treatment. According to the results, JZ34 showed lower accumulation of ROS, less membrane damage and higher antioxidant enzyme activity after LK treatment. Besides, JZ34 also keeps higher K+/Na+ content, higher Ca2+ and Mg2+ content than JZ18 in both shoots and roots. Our genetic analysis revealed that the two additive-dominance-epistasis major genes plus additive-dominance polygene genetic model (E-1) was the optimum model associated with LK resistance based on root trait. The major QTL intervals were finally obtained by the bulked segregant sequencing (BSA-seq) analysis, which were 2.38 Mb at the end of chromosome 4 and 1.38 Mb at the chromosome 6. This is consistent with the analysis of the genetic model. A total of 8 genes were selected in the two candidate regions, which exhibited close related to ion and antioxidant signaling. These findings provided the inheritance pattern and foundation for further molecular mechanisms study of tomato LK resistance.

“…Minor gene action is determined by the form of interaction that occurs in both interactions between alleles at the same locus. Ye et al (2017), for quantitative characters, interactions between alleles can occur in the form of additive and dominant interactions as well as interactions between alleles at different loci (epistasis).…”

Abstract. Suwignyo B, Arifin L, Umami N, Muhlisin, Suhartanto B. 2021. The performance and genetic variation of first and second generation tropical alfalfa (Medicago sativa). Biodiversitas 22: 3265-3270. This study aimed to compare the growth performance, nutrient content, seed viability, and genetic variation of first- and second-generation alfalfa (Medicago sativa L.). First and second-generation alfalfa seeds were obtained from the Forage and Pasture Science Laboratory, Department of Animal Nutrition and Feed Science, Faculty of Animal Science, Universitas Gadjah Mada (UGM), Yogyakarta, Indonesia. First generation alfalfa (F1) seeds were obtained from cross breeding of two different parental alfalfa varieties, namely, Canadian and local. The second-generation (F2) seeds were obtained from plants of the first-generation alfalfa (F1). A randomized design experiment was conducted using the two types of alfalfa (first- and second generation). Alfalfa from Canada as female parent was used as the baseline in the genetic masker test. Seeds were planted in a polybag, watered twice a day, and received 12 hours of daylight and 4 hours of artificial light. Plants were then harvested 8 weeks after planting by cutting the plant canopy. Genetic variation was examined using the Inter Simple Sequence Repeat (ISSR) method followed by descriptive analysis. Germination, plant height, dry matter content, organic matter, and crude protein were assessed as variables using a Student’s T-test. Our results showed that germination, plant height, leaf color, and nutrient content (dry matter, organic matter, and crude protein) of the first- and second-generation alfalfa plants were not significantly different. However, the second-generation alfalfa demonstrated better seed viability than the first generation plants, then it can be categorized as a new genotype (tropical alfalfa) based on genetic variation analysis.
