“…Studies have shown that the latitudinal distribution of wheat ranges from 67°N to 45°S, while that of rice is only from 53°N and 34°S ( Han et al., 2002 ; Zhao et al., 2018 ). Given that environmental adaptation is closely associated with the chromosome polyploid level, genome size and light adaptation ( Dubcovsky and Dvorak, 2007 ; Amo et al., 2022 ), wheat could have a stronger tolerance to variation in sowing date than rice.…”

Rapidly global urbanization and economic growth in the past several decades have resulted in a sharp contraction of arable areas worldwide. However, food supply requirements are quickly increasing due to higher living standards and larger populations. Therefore, food crises are still a major threat to human society. The conflict between farmland areas and the increasing need for essential supplies is becoming acuter in China. Therefore, we suggest that a novel strategy would address the issue, in which temporal and spatial arrangement of wheat sowing dates would be highly focused.

“…Numerous studies investigated the impact of Ppd-1 genes on various aspects of plant development. It has been found that Ppd-1 genes strongly influence on yield-related traits in wheat, including the number of kernel-producing spikelets, spike length, plant height, leaf size, thousand grain weight and spike fertility (Tanio and Kato 2007 ; Seki et al 2011 , 2013 ; Langer et al 2014 ; Kiss et al 2014 ; Cho et al 2015 ; Zhang et al 2015 ; Boden et al 2015 ; Grogan et al 2016 ; Steinfort et al 2017b ; Jones et al 2017 ; Prieto et al 2018 ; Ramirez et al 2018 ; Arjona et al 2018 , 2020 ; Ochagavía et al 2018 ; Pérez-Gianmarco et al 2019 , 2020 ; Sun et al 2020 ; Amo et al 2022 ; Fait and Balashova 2022 ; Errum et al 2023 ). However, the majority of these studies focused on the impact of insensitive and sensitive alleles on agronomic traits, identifying structural variations within the Ppd-1 region in bread wheat populations using PCR-based methods to detect fragment size differences.…”

Key message PHOTOPERIOD-1 homoeologous gene copies play a pivotal role in regulation of flowering time in wheat. Here, we show that their influence also extends to spike and shoot architecture and even impacts root development. Abstract The sequence diversity of three homoeologous copies of the PHOTOPERIOD-1 gene in European winter wheat was analyzed by Oxford Nanopore amplicon-based multiplex sequencing and molecular markers in a panel of 194 cultivars representing breeding progress over the past 5 decades. A strong, consistent association with an average 8% increase in grain yield was observed for the PpdA1-Hap1 haplotype across multiple environments. This haplotype was found to be linked in 51% of cultivars to the 2NS/2AS translocation, originally introduced from Aegilops ventricosa, which leads to an overestimation of its effect. However, even in cultivars without the 2NS/2AS translocation, PpdA1-Hap1 was significantly associated with increased grain yield, kernel per spike and kernel per m2 under optimal growth conditions, conferring a 4% yield advantage compared to haplotype PpdA1-Hap4. In contrast to Ppd-B1 and Ppd-D1, the Ppd-A1 gene exhibits novel structural variations and a high number of SNPs, highlighting the evolutionary changes that have occurred in this region over the course of wheat breeding history. Additionally, cultivars carrying the photoperiod-insensitive Ppd-D1a allele not only exhibit earlier heading, but also deeper roots compared to those with photoperiod-sensitive alleles under German conditions. PCR and KASP assays have been developed that can be effectively employed in marker-assisted breeding programs to introduce these favorable haplotypes.

“…The control of vernalization is regulated by one or several dominant alleles at the Vrn-1 loci [3], with homologous genes located on the long arms of chromosomes 5A, 5B, and 5D, respectively [5,6]. The photoperiodic genes, namely Ppd-D1 (Ppd1), Ppd-B1 (Ppd2), and Ppd-A1 (Ppd3), are located on chromosomes 2D, 2B, and 2A, respectively [7]. The presence of both the photoperiodic gene Ppd-D1a and the vernalization gene Vrn-D1 alleles in winter wheat, under winter conditions and specific genotypes, substantially improves the consistency of flowering timing [7].…”

Wintergrazer-70 and Ganyin No1 are high-yield forage varieties suitable for cultivation in high-altitude areas of Tibet (4300 m above sea level). Ganyin No1 was developed from Wintergrazer-70, with the latter serving as its parent variety. Ganyin No1 was identified as a spring variety, and subsequent RNA sequencing was conducted. RNA sequencing analysis identified 4 differentially expressed genes related to vernalization and 28 genes related to photoperiod regulation. The Sc7296g5-i1G3 gene is related to the flowering inhibition of rye, which may be related to the phenotypic difference in the Ganyin No1 variety in winter and spring. This finding provides valuable insights for future research on Ganyin No1, especially in addressing feed shortages in Tibet during winter and spring.
