Determinate Growth Habit

Snap bean is a vegetable crop presenting high requirements of mineral nutrients, such as nitrogen (N). However, studies on the response of this crop to N fertilizationare scarce, mainly with determinate growth habit genotypes, making it difficult to manage thisnutrient supply. The aim of this study was to evaluate the nitrogen nutrition and the productive performance of snap bean withdeterminate growth habit as a function of N sources and rates. The experiment was carried out inpots, under greenhouse conditions, inaEutrophicRed Oxisolwith 36.60 g dm-3of soil organic matter content.The cultivar ‘Macarrãorasteiro’TopSeedwas grownin a completely randomized design at factorial scheme 3x4, with four replications. It was studied three sources of N (urea, ammonium sulfate and sulfammo) and four rates (0, 40, 80 and 120 kg N ha-1), applied20% at sowing time, 40% at 12 days after emergence (DAE) and 40% at 20 DAE.It was evaluatedthe N content of the index leafandtheNaccumulationinshoots, the plant height at the endof the cycle and the number, total fresh mass, mean fresh mass and mean length of pods.The N content of the index leaf and N accumulation in shoots were linearly increased by the N rates, regardless of the N source, while the plant height and the pod’s characteristics werenotinfluenced by anyof the factors studied

Determinate Growth Habit

Plant height, determinate growth habit, and brachytic stem are 3 major plant-type traits of soybean. In this report, a population of 151 recombinant inbred lines (RILs) derived from the cross of Bogao (high stature, indeterminate growth habit, and normal stem) and Nannong 94-156 (short stature, determinate growth habit, and brachytic stem) was used to map genes and quantitative trait loci (QTLs) for 3 plant-type traits and to reveal the effects of brachytic stem on yield-related traits including seed yield, apparent biological yield, apparent harvest index, plant height, and days to maturity. The results indicated that brachytic stem (sb) and determinate growth habit (dt1) were mapped on linkage groups B2 and L, respectively. Two major QTLs related to plant height were detected and mapped on linkage group L near dt1, and 0.6 cM above the Sb locus on linkage group B2 across 2 years. These 2 QTLs explained 15.1% and 52.7% of the phenotypic variation, and decreased plant height by 9.2 and 17.6 cm, respectively. It was found that only one QTL was detected and mapped on linkage group L near dt1 across 2 years. Lines with brachytic stem had shorter plant height, lower biomass, yield, and harvest index, and essentially no differences in days to maturity when compared with normal stem lines.

Abstract Growth habit is a plant architectural trait in grain legumes with no exception of horse gram. Determinacy and indeterminacy are the two types of growth habits reported in horse gram. Relative advantages of the two types of growth habit depend on the production systems to which cultivars are targeted. Dependable information on genetics of growth habit provide clues for adopting the most appropriate selection strategy to breed high yielding horse gram varieties with desired growth habit. Taking cues from the past studies, we hypothesize that growth habit in horse gram is controlled by two genes displaying inhibitory epistasis and indeterminacy is dominant over determinacy. To test this hypothesis, we monitored the inheritance of growth habit in F1, F2 and F3 generations derived from two crosses involving parents differing for growth habit. Contrary to our hypothesis, determinate growth habit of F1s of both the crosses suggested dominance of determinacy over indeterminacy. A good fit of observed segregation of F2 plants to that of the hypothesized segregation in the ratio of 13 determinate: 3 indeterminate plants, besides confirming dominance of determinacy, suggested classical digenic inhibitory epistatic control of growth habit. These results were further confirmed in F3 generation based on goodness of fit between observed numbers of plants segregating for determinacy and indeterminacy and those expected in the ratio of 49 determinate: 15 indeterminate plants. To the best of our knowledge, this is the first report on the inheritance of growth habit in horse gram.

SummaryThe antiflorigenic signal SELF-PRUNING, which controls growth habit, exerts its effects through auxin transport, signaling and metabolism in tomato.AbstractThe SELF PRUNING (SP) gene is a key regulator of growth habit in tomato (Solanum lycopersicum). It is an ortholog of TERMINAL FLOWER 1, a phosphatidyl-ethanolamine binding protein with anti-florigenic activity in Arabidopsis thaliana. A spontaneous loss-of-function sp mutation has been bred into a large number of industrial tomato cultivars, as it produces a suite of pleiotropic effects that are favorable for mechanical harvesting, including determinate growth habit, short plant stature and simultaneous fruit ripening. However, the physiological basis for these phenotypic differences has not been thoroughly explained. Here, we show that the sp mutation alters polar auxin transport as well as auxin responses such gravitropic curvature and elongation of excised hypocotyl segments. We further demonstrate that free auxin levels and auxin-regulated gene expression patterns are altered in sp, with epistatic effects of diageotropica, a mutation in a cyclophilin A protein-encoding gene. Our results indicate that SP impacts growth habit in tomato, at least in part, via changes in auxin transport and responsiveness. These findings hint at novel targets that could be manipulated in the control of growth habit and productivity.

Determinate Growth Habit

This review is devoted to the analysis of molecular genetic mechanisms of controlling the type of growth habit of grain legumes (pea, soybean, common bean, vigna); it provides information on the known homologous genes TFL1, LFY, AP1, FUL, FT, and FD. Significant changes in plant architecture were during domestication of grain legumes. Many wild relatives of legumes are characterized by an indeterminate growth habit type, cultivated plants are characterized by indeterminate and determinate types. In plants with a determinate growth habit type, terminal inflorescence is formed at transition from the vegetative phase to the reproductive phase. These plants are characterized by a complex of features: simultaneous maturation of beans, resistance to lodging, etc. In indeterminate type of growth habit, the apical shoot meristem remains active during plant life. The main genes responsible for the plant transition to flowering are the homologs of the Arabidopsis genes LFY, TFL1, AP1. TFL1 gene is responsible for maintaining of growth of the shoot apical meristem; its homologs were identified in pea (PsTFL1a), soybean (Dt1/ GmTfl1), common bean (PvTFL1y), cowpea (VuTFL1). The identification and characterization of the genes responsible for the type of stem growth habit are necessary for the successful selection of modern varieties suitable for mechanized cultivation. Design of molecular markers that diagnose this important breeding trait at early plant development stages, will help determine the type of stem growth habit.

Determinate Growth Habit

Growth characteristics were investigated in 40 temperate herbaceous perennial species in relation to habitat. Some forest plants completed leaf development and shoot elongation before and during canopy closure. This rapid foliation involved expansion of only a small number of foliage leaves, disappearance of scale leaves, and a reduced shoot height. These species showed a determinate growth habit and early initiation of flowering. These are characteristics considered to have evolved in association with shade stress. In contrast, plants mainly found in exposed sites with a tall-herb vegetation continued leaf development and shoot elongation even in mid-August. These species possessed a determinate growth habit, not investing photosynthates into sexual organs at least during early vegetative growth, and showed late initiation of flowering. These characteristics appear to be related to competition for light. Plants in exposed sites without tall herbs also continued leaf development in mid-August, but they had rosette forms coupled with indeterminate growth habit and varying time of flowering initiation. These traits allow the plants to make maximum use of the growing season and are advantageous to vegetative regeneration after disturbance. On the basis of the leaf-development duration in this study and dormant states obtained in a previous study, three growth-rhythm categories can be recognized in relation to habitat. Key words: growth form, growth habit, growth rhythm, leaf-development duration, flowering initiation, shade stress, disturbance, competition.
