“…Similarly, we found regional differentiation in the Ln gene, which is responsible for soybean leaf shape and the four-seed pod 32,33 , and the T locus, which regulates pubescence color 34,35 , that were not detected in the screening for domestication and improvement selection described above. The mutant Ln allele was mainly distributed in northeastern China and northern China (Fig.…”

“…A study conducted by You et al (1995) in Southern China revealed that the lower number of soybean seeds per pod might be associated with the broader leaflet shape. Similarly, Jeong et al (2012) also found that narrow leaflet soybean varieties apparently had more seeds per pod than those of broad leaflet varieties. This study has revealed a potential way to improve seed yield.…”

Abstract. Krisnawati A, Adie MM. 2017. The leaflet shape variation from several soybean genotypes in Indonesia. . Leaves are part of the plant organs which are of importance to sustain the plant's life. Generally, each plant has a varied leaflet shape depending on many factors. Soybean, as one of an important source of protein vegetable, has a diverse plant shape among its genotypes. The objective of the research was to evaluate the variation of leaflet shape of 150 soybean (Glycine max L.) genotypes and its relation to another growth and morphological characters. The leaflet shape of 150 soybean genotypes was intensively in Kendalpayak Research Station, Malang (Indonesia) from February to May 2016. This field experiment was conducted in randomized block design with two replicates. The leaf characterization of 150 soybean genotypes using LSI (Leaf Shape Index) method. Analysis of variance of observed soybean genotypes in terms of maturity traits and morphological attributes showed a significantly different among soybean genotypes, except for harvest index (HI) parameter. This indicates that there was variability in morphological characters among of 150 soybean genotypes. The LSI value ranged from 1.40 to 3.05, in average of 2.04. Of all observed soybean genotypes, most of their morphological performance was an intermediate size (110 genotypes), while another 17 genotypes was a broad leaflet, and the rest (23 genotypes) had a narrow leaflet. Genotypes with an intermediate leaflet apparently possessed the different morphological characters of seed in terms of size, weight/plant and yield compared to those leaflet shape of other genotypes. Among the broad leaflet group, accession No. 92 could be prospectively used as a gene donor for improving soybean yield potential in Indonesia due to its high yield production (3.05 t/ha), early maturity, and large seed size. In the group of intermediate leaflet, accession No. 18 could also be used as a potential gene donor showed in its high yield production (3.07 t/ha), early maturity, and large seed size. Meanwhile, the potential gene donor in narrow leaflet group, which could be further used were two genotypes (accession No. 20 and No. 22).

“…Ln has been mapped to a genomic region that includes a single gene – Gm-JAG1 – a homolog of the A. thaliana zinc-finger gene JAGGED . A single amino acid substitution (D9H) in the transcriptional repressor EAR motif of Gm-JAG1 is likely to be the causal ln mutation, rendering Gm-JAG1 non- or hypofunctional (Jeong et al, 2012). In addition to altering leaf morphology, the ln mutation affects the number of seeds per fruit (You et al, 1995; Dinkins et al, 2002).…”

Proteins change over the course of evolutionary time. New protein-coding genes and gene families emerge and diversify, ultimately affecting an organism’s phenotype and interactions with its environment. Here we survey the range of structural protein change observed in plants and review the role these changes have had in the evolution of plant form and function. Verified examples tying evolutionary change in protein structure to phenotypic change remain scarce. We will review the existing examples, as well as draw from investigations into domestication, and quantitative trait locus (QTL) cloning studies searching for the molecular underpinnings of natural variation. The evolutionary significance of many cloned QTL has not been assessed, but all the examples identified so far have begun to reveal the extent of protein structural diversity tolerated in natural systems. This molecular (and phenotypic) diversity could come to represent part of natural selection’s source material in the adaptive evolution of novel traits. Protein structure and function can change in many distinct ways, but the changes we identified in studies of natural diversity and protein evolution were predicted to fall primarily into one of six categories: altered active and binding sites; altered protein–protein interactions; altered domain content; altered activity as an activator or repressor; altered protein stability; and hypomorphic and hypermorphic alleles. There was also variability in the evolutionary scale at which particular changes were observed. Some changes were detected at both micro- and macroevolutionary timescales, while others were observed primarily at deep or shallow phylogenetic levels. This variation might be used to determine the trajectory of future investigations in structural molecular evolution.
