Competition effect of wild oat (Avena ludoviciana L.)

پژوهشهای زراعی ایران, 2009
To investigate the effects of wild oat competition on yield and yield components of two contrasting winter wheat cultivars, an experiment was conducted at the Research Station of Plant, Pest and Disease Institute of Karaj, during 2003-2004 growing season

Genetic diversity for grain nutrients in wild emmer wheat: potential for wheat improvement [PDF]

Annals of Botany, 2010
Micronutrient malnutrition, particularly zinc and iron deficiency, afflicts over three billion people worldwide due to low dietary intake. In the current study, wild emmer wheat (Triticum turgidum ssp. dicoccoides), the progenitor of domesticated wheat, was tested for (1) genetic diversity in grain nutrient concentrations, (2) associations among grain ...

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

Advanced Science, EarlyView.
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 ...

Achieving High‐Density and Stress‐Resilient Maize Breeding Via Germplasm Innovation

Advanced Science, EarlyView.
Global population growth and climate change have exacerbated the global food crisis. This perspective presents a conceptual framework focusing on enhancing population advantages. Several novel breeding objectives are proposed to improve density tolerance and stress resistance for yield improvement.

Variation in CoxII Intron in the Wild Ancestral Species of Wheat [PDF]

Hereditas, 2004
To study the maternal lineage and evolution of polyploid species of wheat, variation in mitochondrial DNA was investigated in Triticum and Aegilops by PCR-aided RFLP analysis. A 1.3 kb region containing the intron of coxII was studied using 20 accessions from five species of Sitopsis section of Aegilops, one species of Einkorn wheat, four species of ...

Secreted Nonstructural Protein 3 is a Pathogenic Determinant of Orbivirus

Advanced Science, EarlyView.
This study uncovers a conserved PIP2‐dependent secretory pathway of orbivirus NS3 that induces vascular leakage. Pharmacological disruption of PIP2‐NS3 interaction significantly reduces viral pathogenicity and provides protective efficacy in murine models, establishing PIP2‐mediated NS3 secretion as both a key virulence determinant and a promising ...

Wild oat competition in short-statured wheat

California Agriculture, 1991
Wild oat and wheat were synchronized in their development and were shown to be equally competitive in southern California studies. Competition effects of wild oat were most evident in wheat after the stem elongation stage.

Variation in key leaf photosynthetic traits across wheat wild relatives is accession dependent not species dependent.

New Phytologist, 2020
The wild relatives of modern wheat represent an underutilized source of genetic and phenotypic diversity and are of interest in breeding owing to their wide adaptation to diverse environments. Leaf photosynthetic traits underpin the rate of production of

Genome size variation in diploid and tetraploid wild wheats [PDF]

AoB PLANTS, 2010
Intra- and interspecific variations of C-values and the relationship between habitat factors and genome size were studied in natural populations of diploid and tetraploid wild wheats.The 1C nuclear DNA content of 376 individual plants representing 41 populations of diploid and tetraploid wild wheats was determined by flow cytometry (FCM) and correlated

A Virus‐Inducible E3–RLCK–MADS Module Coordinates Suppression of Plant Immunity and Fertility in Rice

Advanced Science, EarlyView.
ABSTRACT Viruses often hijack host developmental programs to promote infection, but the mechanistic links between reproductive regulation and antiviral immunity remain incompletely understood. Here, we identify a virus‐triggered hierarchical degradation cascade that links antiviral immunity and fertility regulation in rice. We show that the rice grassy
