The type of stem growth is one of the key features in determining plant architectonics. Stem growth type is an economically important trait. It interconnects with stem length, flowering duration, yield, resistance to lodging, and suitability of mechanized cultivation. Mutations in the TFL1 gene and its homologs have been demonstrated to change meristem indeterminacy across genera. The aim of this work was to characterize and compare the structural organization of TFL1-like genes in representatives of the tribe Phaseoleae (pigeonpea Cajanus cajan, soybean Glycine max, common bean Phaseolus vulgaris, adzuki bean Vigna angularis, mung bean V. radiata, and cowpea V. unguiculata) based on in silico analysis, including analysis of nucleotide sequences, predicted elements in promoter regions, predicted amino acid sequences, putative functional domains and 3D protein structures. We investigated TFL1 (one gene for adzuki bean, four copies for soybean, two copies for other studied species), ATC (two copies for soybean, one gene for other investigated species), and BFT (two copies for soybean, one gene for other studied species) gene family members found in whole-genome sequences databases available for representatives of the tribe Phaseoleae. The presence of duplicated copies for all genes in soybean may be a result of the last genome duplication event during the evolution of this species. Duplication of TFL1 gene to two copies in most of studied species of the tribe Phaseoleae is probably accompanied by the maintenance of the functional state of these genes. The exception is VrTFL1.2 of V. radiata, which likely had lost its functionality. This work broadens the existing data about the number of gene copies, their structural divergence and evolution, and the expected functional differences. This information will be important for understanding the molecular genetic mechanisms underlying the maintenance of indeterminacy in the growth of the shoot apical meristem, as well as in the control of the transition to the reproductive phase of plant development.

Background. Cowpea is an important legume crop of great nutritional and economic value, ranking fourth in the world among leguminous crops in the area of cultivation. This crop is known to tolerate high temperatures and droughts, so new cowpea cultivars adapted to the local arid conditions of the Lower Volga are of considerable interest.Materials and methods. Mass and individual selection techniques were applied to develop new cultivars from cowpea landraces held in the VIR collection. Selection was carried out at Astrakhan Experiment Station of VIR in 2012–2018, and variety trials took place in 2019–2021.Results. Cvs. ‘Samma Nova’ and ‘Pasta Grin’ were released for vegetable use. The pod yield of ‘Samma Nova’ is 12.18–14.85 t/ha, seed yield is 0.92–1.14 t/ha, protein content is 28.8% in seeds and 27.1% in pods, and its growing season is 57–66 days. The cultivar is bushy, with synchronous pod and seed maturation, suitable for mechanized cultivation. The pod yield of ‘Pasta Grin’ is 24.68–25.84 t/ha, seed yield is 0.82–1.04 t/ha, protein content is 29.1% in pods and 23.6% in seeds. It is a mid-season cultivar, with a rambling stem, intended for growing on a trellis. Both cultivars significantly exceeded the reference (cv. ‘Sibirsky Razmer”) in most of the studied indicators. The breeding work with cowpea accessions showed that pod harvesting at the commercial ripeness stage stimulated plants to develop new pods, which extended the duration of fruiting and increased productivity. The maximum number of pods in all studied cultivars was formed in the first 20 days of the fruiting period.Conclusion. In 2022, according to the results of competitive and local trials, cvs. ‘Samma Nova’ and ‘Pasta Grin’ were included in the State Register for Selection Achievements (National List). The zones of cultivation and seed production for these cultivars are Astrakhan and Volgograd Provinces, Krasnodar and Stavropol Territories, and the Republic of Crimea.

Flavonoids play a crucial role in plant metabolism. Many of them have antioxidant activity, and they are also pigments that render a variety of colors to plant tissues. Foods rich in flavonoid compounds are considered as functional components of a healthy diet. Currently, there is an increased interest in studying genetic mechanisms underlying the coloration of plants. Flavonoid biosynthesis pathways are controlled by two groups of genes. Structural genes encode enzymes, while regulatory genes are responsible for transcription factors that activate the expression of structural genes. Transcription factors that belong to R2R3-Myb, bHLH-Myc and WDR families form the ternary MBW complex, which is involved in regulating the expression of structural genes of flavonoid biosynthesis. The mechanisms of regulation of the anthocyanins and proanthocyanidin biosynthesis by the MBW complex are described in detail for the model plant Arabidopsis thaliana L. This review summarizes data on the regulation of phenolic pigment biosynthesis and the features of phenolic pigment accumulation in plant tissues in the main representatives of the Phaseoleae tribe: soybean Glycine max (L.) Merr., common bean Phaseolus vulgaris L., adzuki bean Vigna angularis (Willd.) Ohwi & Ohashi, and cowpea V. unguiculata (L.) Walp. The species discussed in this review are the most important food legumes in many countries of the world and they comprise the staple food in diets of millions of people. Identification and characterization of the genes controlling the flavonoid biosynthesis pathways are necessary for successful breeding of modern varieties with an increased dietary value. Identification of the flavonoid accumulation patterns is essential for solving the problem of broadening the diversity of plant products.
