qGLF5 from Oryza rufipogon Griff. improves kernel shape, plant architecture, and yield in rice
Theor Appl Genet. 2023 Oct 17;136(11):225. doi: 10.1007/s00122-023-04478-9.ABSTRACTA novel QTL qGLF5 from Oryza rufipogon Griff. improves yield per plant and plant architecture in rice. Kernel size and plant architecture are critical agronomic traits that are key targets for improving crop yield. From the single-segment substitution lines of Oryza rufipogon Griff. in the indica cultivar Huajingxian74 (HJX74) background, we identified a novel quantitative trait locus (QTL), named qGLF5, which improves kernel shape, plant architecture, and yield per plant in rice. Compared with the control HJX74, the plant height, panicles p...

Introgression of the bread wheat D genome encoded Lr34/Yr18/Sr57/Pm38/Ltn1 adult plant resistance gene into Triticum turgidum (durum wheat)
Theor Appl Genet. 2023 Oct 17;136(11):226. doi: 10.1007/s00122-023-04466-z.ABSTRACTKEY MESSAGE: Lack of function of a D-genome adult plant resistance gene upon introgression into durum wheat. The wheat Lr34/Yr18/Sr57/Pm38/Ltn1 adult plant resistance gene (Lr34), located on chromosome arm 7DS, provides broad spectrum, partial, adult plant resistance to leaf rust, stripe rust, stem rust and powdery mildew. It has been used extensively in hexaploid bread wheat (AABBDD) and conferred durable resistance for many decades. These same diseases also occur on cultivated tetraploid durum wheat and emmer wheat but transfer of D genome...

A complex locus regulates highly lobed-leaf formation in Brassica juncea
This study involved the identification of 55 LMI1-like genes in 16 species of Brassicaceae through syntenic analysis. We classified these LMI1-like genes into two types, namely LMI1-type and RCO-type, based on their phylogenetic relationship. Additionally, we proposed two independent lineage-specific evolution routes for RCO following the divergence of Aethionema. Our findings revealed that the LMI1-like loci responsible for lobed-leaf formation in Brassica species are located on the LF subgenomes. For B. juncea (T84-66V2), we discovered that the complex locus underwent duplication through segments of nucleic acid sequence...

Dissecting the genetic architecture of root-related traits in a grafted wild Vitis berlandieri population for grapevine rootstock breeding
In this study, we used a wild population of an American Vitis species (V. berlandieri) to analyze the genetic architecture of the root-related traits of rootstocks in a grafted context. We studied a population consisting of 211 genotypes, with one to five replicates each (n = 846 individuals), plus four commercial rootstocks as control genotypes (110R, 5BB, Börner, and SO4). After two independent years of experimentation, the best linear unbiased estimates method revealed root-related traits with a moderate-to-high heritability (0.36-0.82) and coefficient of genetic variation (0.15-0.45). A genome-wide association study w...
