The objective of this study was to elucidate the genetic control of the semi- determinate growth habit in tomato (Lycopersicon esculentum Mill.). A semidetermi- nate tomato line was crossed with determinate and indeterminate lines; their F1, F2, and backcrosses were grown; and the growth habit recorded and analyzed. Plants with six or more inflorescences on the main stem were defined as semidetermina te, while those with fewer were defined as determinate. The F2 and backcross to determinate…

Characterization and mapping of Dt1 locus which co-segregates with CcTFL1 for growth habit in pigeonpea
TLDR
This study clearly demonstrated that CcTFL1 is a candidate gene for growth habit in pigeonpea and a user-friendly marker was developed in the present study which will allow low-cost genotyping without need of automation.
Parallel domestication with a broad mutational spectrum of determinate stem growth habit in leguminous crops.
TLDR
It is shown that indeterminate stem growth in wild mungbean is modulated by a single gene, VrDet1, which encodes a signaling protein of shoot apical meristems, and that interspecifically and functionally conserved promoters possess cis-regulatory elements that are highly conserved in kind but greatly variable in number and order, demonstrating the evolutionary dynamics of regulatory sequences.

TLDR
Comparison of modern data on the genetic control of stem growth habit in the representatives of different taxa of angiosperms points to the evolutionary conservation of molecular genetic mechanisms controlling the initiation of flowering, as well as to the conserved functionality of the genes involved in this process.
Genealogy and fine mapping of obscuravenosa, a gene affecting the distribution of chloroplasts in leaf veins, and evidence of selection during breeding of tomatoes (Lycopersicon esculentum; Solanaceae).
TLDR
The data suggest that the prevalence of obv in nearly all processing varieties may have resulted from its tight linkage to a QTL conferring a more compact, and horticulturally desirable, plant habit.
Further evidence for the genetic basis of qualitative traits and their linkage relationships in dolichos bean (Lablab purpureus L.)
An investigation on inheritance of qualitative traits in dolichos bean revealed biallelic monogenic control of photoperiod-induced sensitivity to flowering time and flower colour in F 2 and F 3
Innovation of a Regulatory Mechanism Modulating Semi-determinate Stem Growth through Artificial Selection in Soybean
TLDR
It is shown that semi-determinacy in soybean is modulated by transcriptional repression of Dt1, the functional ortholog of TFL1, in SAMs, which is further demonstrating the evolutionary novelty of the regulatory mechanism underlying stem growth in soy bean.
Dt2 Is a Gain-of-Function MADS-Domain Factor Gene That Specifies Semideterminacy in Soybean[C][W]
This work describes mapped-based cloning and characterization of a gain-of-function mutation (Dt2) that specifies semideterminate stem termination in soybean. Dt2 represents an evolutionary novelty
SlGID1a Is a Putative Candidate Gene for qtph1.1, a Major-Effect Quantitative Trait Locus Controlling Tomato Plant Height
Plant height is an important agronomic trait in crops. Several genes underlying tomato (Solanum lycopersicum) plant height mutants have been cloned. However, few quantitative trait genes for plant
Revolutions in agriculture chart a course for targeted breeding of old and new crops
TLDR
It is argued that in the short term, more legumes such as beans are the best option, and in such plants targeted changes in antiflorigen genes were and will continue to be key for large-scale production.
