TL;DR: WGDI as mentioned in this paper is a Python-based command-line tool that facilitates comprehensive analysis of recursive polyploidization events and cross-species genome alignments, and it supports three main workflows (polyploid inference, hierarchical inference of genomic homology, and ancestral chromosome karyotyping).

TL;DR: In this article , the authors reported the assembly of a telomere-to-telomere gap-free genome of the elite watermelon inbred line G42 by incorporating high-coverage and accurate long-read sequencing data with multiple assembly strategies.

TL;DR: In this paper , the authors review the results of this research effort that have led to the identification and characterization of several core Pi starvation signaling components, including sensors, transcription factors, microRNAs (miRNAs), and miRNA inhibitors, kinases, phosphatases, and components of the proteostasis machinery.

TL;DR: In this article , the authors identified two new semi-dwarfing mutants named je99 and je05 in the Jing-house wheat mutant and collectively mapped these mutants to the same region of the wheat genome.

TL;DR: In this article , a review of the numerous redox pathways, located in the various subcellular compartments that produce NO, in addition to the mechanisms underpinning NO scavenging, is presented.

TL;DR: In this article , an ABA1-independent ABA biosynthetic pathway starting upstream of zeaxanthin was investigated in both Arabidopsis and rice, showing that β-apo-11-carotenal, 9-cis-epoxy-CAROTENOID DIOXYGENASE and ABSCISIC ALDEHYDE OXIDASE 3 (AAO3) are intermediates of this pathway.

TL;DR: In this article , a three-variance-component mixed model was integrated with the multi-locus random-SNP-effect mixed linear model (mrMLM) method to establish a new methodological framework, 3VMRMLM, that detects all types of loci and estimates their effects.

TL;DR: In this article , the authors reported the map-based cloning of Rht8 candidate gene, and confirmed that loss of Ribonuclease H-Like 1 (RNHL-D1) is responsible for Rht 8 semi-dwarfing effect.

TL;DR: In this article , the authors review the cascades of nutrient-related sensing and signaling events that involve hormones and highlight nutrient-hormone relations that coordinate root developmental plasticity in plants.

TL;DR: In this paper , a novel locus, Time of Flowering 5 (Tof5), was identified, which promotes flowering and enhances adaptation to high latitudes in both wild and cultivated soybean.

TL;DR: In this paper , the sugar-inducible rice NAC transcription factor OsNAC23 directly represses the transcription of the Tre6P phosphatase gene TPP1 to simultaneously elevate trehalose levels, thus facilitating carbon partitioning from source to sink organs.

TL;DR: In this paper , a zinc-finger transcription factor, drought and salt tolerance (DST), controls nitrate assimilation in rice by regulating the expression of OsNR1.2, a gene showing sequence similarity to nitrate reductase.

TL;DR: In this paper , a widely targeted volatilomics (WTV) method that involves using a "targeted spectra extraction" algorithm to address spectral convolution, constructing a high-coverage MS2 spectral tag library to expand volatile annotation, adapting a multiple reaction monitoring mode to improve sensitivity, and using regression models to adjust for signal drift is presented.

TL;DR: This paper found that 6.7% of the wheat genome falls within the selective sweeps between landraces and cultivars, which harbors the genes known for yield improvement, and found that TaARF12 and TaDEP1 function in epistasis with the classical plant height Rht-1 locus, leading to a "Green Revolution"-based working model for historical wheat breeding.

TL;DR: The concept and practices of Green Super Rice (GSR) have led to a paradigm shift in goals for crop genetic improvement and models of food production for promoting sustainable agriculture as discussed by the authors .

TL;DR: In this paper , a robust phylogenetic framework for evolutionary analyses of the grass family is presented. But the results strongly support the monophyly of 11 subfamilies, but the subfamily Puelioideae was separated into two non-sister clades, one for each of the two previously defined tribes, supporting a hypothesis that places each tribe in a separate subfamily.

TL;DR: In this paper , the authors show that tryptophan synthase β subunit 1 (TSB1) is involved in the coordination of Trp and ABA, thereby affecting plant growth and abiotic stress responses.

TL;DR: In this paper , the authors performed systematic analyses for acquired genes in different plant groups and throughout land plant evolution, and found that relatively recent HGT events occurred in charophytes and all major land plant groups, but their frequency declined rapidly in seed plants.

TL;DR: Zhang et al. as discussed by the authors found that the high-affinity nitrate transporter gene family had expanded in Triticeae and subsequent functional differentiation endowed the expanded family members with saline inducibility, providing a genetic basis for improving the adaptation of wheat to nitrogen deficiency in various habitats.

TL;DR: In this article , a smart breeding scheme, integrated genomic-enviromic prediction (iGEP), is proposed, which uses integrated multiomics information, big data technology, and artificial intelligence (mainly focused on machine and deep learning).

TL;DR: In this paper , the authors performed a comprehensive multiple omics analysis of zmpla1 mutant anthers by integrating transcriptome, metabolome, quantitative proteome, and protein modification data.

TL;DR: In this paper , the authors used guilt-by-association analysis of metabolome and transcriptome data spanning the entire life cycle in rice (Oryza sativa) to aid in understanding the mechanisms underlying important agronomic traits.

TL;DR: In this paper , the authors reported the molecular cloning and characterization of RppC, which encodes an NLR-type immune receptor and is responsible for a major SCR resistance quantitative trait locus.

TL;DR: In this article , the authors presented chromosome-level haploid maps for two A. annua strains with different artemisinin contents to explore the relationships between genomic organization and artemiainin production.

TL;DR: In this paper , the authors identified the long non-coding RNA (lncRNA) MARNERAL Silencing (MARS), localized inside the Arabidopsis marneral cluster, which controls the local epigenetic activation of its surrounding region in response to abscisic acid (ABA).
