Abstract
MADS-box genes play vital roles in multiple biological processes of plants growth and development, especially inflorescence development. In the present study, a comprehensive investigation into the identification and classification of MADS-box genes in Kentucky bluegrass (Poa pratensis) has not been reported. Here, based on the transcriptome of inflorescence, we identified 44 PpMADS-box genes, and gave an overview of the physicochemical properties, phylogeny, protein structures, and potential functions of the proteins encoded by these genes through various bioinformatics software for the first time. Analysis of physicochemical properties revealed that most PpMADS-box were alkaline proteins and possessed similar conserved motifs. Additionally, it was demonstrated that 33 PpMADS-box proteins without signal peptide, leading peptide, transmembrane structure and located in the nucleus were not transported or secreted, so directly played transcriptional regulatory roles in the nucleus. Then, peptide sequences BLAST search and analysis of phylogenetic relationships with MADS-box proteins of P. pratensis, Arabidopsis thaliana, and Oryza sativa were performed. It was found that 44 PpMADS-box proteins were separated into 33 MIKC-type (3 BS, 1 AGL17, 8 AP3/P2, 3 AP1, 5 SEP, 6 SOC and 7 AG genes, respectvely) and 11 type I-type, which include 7 Mγ and 4 Mα. Furthermore, the relative expression levels of the selected 12 genes (MADS3, 15, 16, 17, 18, 20, 24, 27, 30, 36, 38 and 40) at the booting stage, pre-anthesis, anthesis, post-anthesis, and seed filling stage of inflorescences, as well as leaves and roots of the corresponding stages of inflorescences were analyzed, showing that most PpMADS-box genes were highly expressed mainly in young leaves and later inflorescences, and had complex patters in roots. Morever, except for PpMADS30 being highly expressed in the leaves, others were significantly highly expressed in inflorescence and/ or roots, demonstrating PpMADS-box genes also regulate leaves and roots development in plant. This study provides valuable insights into the MADS-box family genes in Kentucky bluegrass and its potential functional characteristics, expression pattern, and evolution in floral organogenesis and even reproduction development. @media print { .ms-editor-squiggler { display:none !important; } } .ms-editor-squiggler { all: initial; display: block !important; height: 0px !important; width: 0px !important; }.

Abstract
Grain yield in bread wheat (Triticum aestivum L.) is largely determined by inflorescence architecture. Zang734 is an endemic Tibetan wheat variety that exhibits a rare triple spikelet (TRS) phenotype with significantly increased spikelet/floret number per spike. However, the molecular basis underlying this specific spike morphology is completely unknown. Through map-based cloning, the causal genes for TRS trait in Zang734 were isolated. Furthermore, using CRISPR/Cas9-based gene mutation, transcriptome sequencing and protein-protein interaction, the downstream signalling networks related to spikelet formation and awn elongation were defined. Results showed that the null mutation in WFZP-A together with deletion of WFZP-D led to the TRS trait in Zang734. More interestingly, WFZP plays a dual role in simultaneously repressing spikelet formation gene TaBA1 and activating awn development genes, basically through the recruitments of chromatin remodelling elements and the Mediator complex. Our findings provide insights into the molecular bases by which WFZP suppresses spikelet formation but promotes awn elongation and, more importantly, define WFZP-D as a favourable gene for high-yield crop breeding.

Cytological and molecular characterizations of a novel 2A nullisomic line derived from a widely-grown wheat cultivar Zhoumai 18 conferring male sterility. PeerJ 2020; 8:e10275.

Abstract
A dwarf, multi-pistil and male sterile dms mutant was previously reported by us. However, the genetic changes in this dms are unclear. To examine the genetic changes, single nucleotide polymorphism (SNP) association, chromosome counting, and high-resolution chromosome fluorescence in situ hybridization (FISH) techniques were employed. By comparing tall plants (T) with dwarf plants (D) in the offspring of dms mutant plants, SNP association analysis indicated that most SNPs were on chromosome 2A. There were three types in offspring of dms plants, with 42, 41 and 40 chromosomes respectively. High-resolution chromosome painting analysis demonstrated that T plants had all 42 wheat chromosomes; the medium plants (M) had 41 chromosomes, lacking one chromosome 2A; while D plants had 40 wheat chromosomes, and lacked both 2A chromosomes. These data demonstrated that dms resulted from a loss of chromosome 2A. We identified 23 genes on chromosome 2A which might be involved in the development of stamens or pollen grains. These results lay a solid foundation for further analysis of the molecular mechanisms of wheat male sterility. Because D plants can be used as a female parent to cross with other wheat genotypes, dms is a unique germplasm for any functional study of chromosome 2A and wheat breeding specifically targeting genes on 2A.
