Introgressed Variation in TaMYB7‐A1 Drives Graded Dormancy and Climate‐Adaptive Pre‐Harvest Sprouting Resistance in Wheat

Advanced Science, Volume 13, Issue 42, 28 July 2026.
TaMYB7‐A1 directly activates TaABI5 to enhance ABA signaling and regulate ABA‐GA homeostasis, enforcing seed dormancy. Its superior allele, derived from wild einkorn introgression, harbors a MITE insertion that elevates expression and two amino acid substitutions that enhance transcriptional activity, collectively generating graded PHS resistance for ...

Cytogenetic Analysis of Altitude‐Associated Chromosome Variations in Campeiostachys nutans From Western Sichuan Plateau Using Multicolor GISH and ND‐FISH Approaches

Ecology and Evolution, Volume 16, Issue 7, July 2026.
The genomic and chromosomal organization of C. nutans was investigated using GISH and ND‐FISH with four oligonucleotide probes. The results showed that repetitive sequence distribution exhibited genome‐specific patterns: the H genome demonstrated high structural stability with low polymorphism, while the St genome showed moderate variation, and the Y ...

Biosystematics and Taxonomic Treatment of Three New Kengyilia Species in the Triticeae (Poaceae)

Ecology and Evolution, Volume 16, Issue 7, July 2026.
Three new Kengyilia species have been discovered. These new species have morphological differences from their closely related species. Three Kengyilia species are allohexaploid and contain the StStYYPP genome. Different Kengyilia have different origins.

Evidence That Sri Lanka Is the Origin of a Rare Nematode Resistance Gene in Rice

Plant Direct, Volume 10, Issue 7, July 2026.
ABSTRACT Meloidogyne graminicola is a destructive and widespread pest in tropical rice‐growing systems, whereas resistance in Oryza sativa remains exceptionally rare. A major quantitative trait locus (QTL) associated with resistance has previously been identified at the distal end of chromosome 11 in the resistant varieties, LD 24 (Sri Lanka) and KPM ...

Cytogenetic features of intergeneric amphydiploids and genome-substituted forms of wheat

Вавиловский журнал генетики и селекции
Synthetic intergeneric amphydiploids and genome-substituted wheat forms are an important source for transferring agronomically valuable genes from wild species into the common wheat (Triticum aestivum L.) genome.

Diploid genome differentiation conferred by RNA sequencing-based survey of genome-wide polymorphisms throughout homoeologous loci in Triticum and Aegilops

BMC Genomics, 2020
Background Triticum and Aegilops diploid species have morphological and genetic diversity and are crucial genetic resources for wheat breeding. According to the chromosomal pairing-affinity of these species, their genome nomenclatures have been defined ...

Stomatal Closure, a Conserved Spore Concentration‐Dependent Response Mediated by Different Stb Genes to Avirulent Isolates of Zymoseptoria tritici

Plant Pathology, Volume 75, Issue 4, July‐August 2026.
Inoculation with different avirulent Zymoseptoria tritici isolates induces stomatal closure in wheat lines carrying either the Stb9 or Stb16q resistance genes. The proportion of closed stomata was positively associated with inoculum concentration, consistent with increased Z. tritici penetration attempts through stomata.

Germination requirements of nine European Aegilops species in relation to constant and alternating temperatures

, 2015
The genus Aegilops represents the secondary gene pool of wheat. A better understanding of the germination behaviour of Aegilops species is important to improve their use in breeding programmes and strengthen their in situ/ex situ conservation.

Wheat's war against stripe rust: Integrating host immunity, genomics and breeding for durable resistance

The Plant Genome, Volume 19, Issue 2, June 2026.
Abstract Wheat (Triticum aestivum L.), a foundation of global food security, faces persistent threats from stripe rust caused by Puccinia striiformis f. sp. tritici (Pst). The pathogen thrives in cool and humid environments and regularly causes epidemics that lead to severe yield losses.
