The deterioration in the quality of ex situ conserved seed over time reflects a combination of both physical and chemical changes. Intraspecific variation for longevity is, at least in part, under genetic control. Here, the grain of 183 bread wheat accessions maintained under low-temperature storage
Carotenoid β-hydroxylases attach hydroxyl groups to the β-ionone rings (β-rings) of carotenoid substrates, resulting in modified structures and functions of carotenoid molecules. We cloned and characterized two genes (each with three homeologs), HYD1 and HYD2, which encode β-hydroxylases in wheat.
The present investigation has been undertaken to evaluate role of Wheat grass extract in modifying mercury-induced biochemical alterations in albino rats. Mercuric chloride 5 mg/kg body weight i.p. was given on 11, 13 & 15th day of the experiment. Wheat grass extract (400 mg/kg) and Quercetin (10
Pre-harvest sprouting (PHS) and seed longevity (SL) are complex biological processes of major importance for agricultural production. In the present study, a recombinant inbred line (RIL) population derived from a cross between the German winter wheat (Triticum aestivum L.) cultivars History and
Gaseous pollutant emissions from brick kiln industries deteriorate the current state of ambient air quality in Pakistan and worldwide. These gaseous pollutants affect the health of plants and may decrease plant growth and yield. A field experiment that was conducted to monitor the concentration of
Transmission electron microscopy (TEM) and fluorescence microscopy studies revealed that the metaphloem sieve elements (MSEs) in the ventral vascular bundle of the caryopses of developing wheat (Triticum aestivum L.) undergo a unique type of programmed cell death (PCD). Terminal deoxynucleotidyl
In previous studies, we first isolated one different protein β-1,3-glucanase using two-dimensional electrophoresis and matrix-assisted laser desorption/ionization time-of-flight mass spectrometry from normal wheat (Triticum aestivum L.) and chemical hybridization agent-induced male sterility (CIMS)
Fusarium head blight, also called scab, is a serious disease of small grain cereals and maize. Scab can not only cause yield loss, more seriously is that it can also deteriorate seed quality by contaminating the infected grains with trichothecenes toxins harmful to human and animal health.
A pair of degenerate primers were designed based on NBS (nucleotide binding site, NBS) domain of resistance(R) gene and used to perform PCR with cDNA from the translocation line 6VS/6AL of Triticum aestivum-Haynaldia villosa. A clone (N7) characterized with NBS was obtained by sequencing analysis.
Timely prediction of seed viability loss over long-term storage represents a challenge in management and conservation of ex situ plant genetic resources. However, little attention has been paid to study the process of seed deterioration and seed aging signals under storage. An attempt was made here
The essential oil of Cymbopogon martinii was tested for its potency as a botanical pesticide to protect stored wheat (Triticum aestivum) and gram (garbanzo bean, Cicer arietinum) from insect infestation. The C. martinii oil was potent as a fumigant in stored gram. The oil was an effective repellent
The pattern of lectin histochemistry in formalin fixed, paraffin embedded normal jejunal and subtotal villous atrophy specimens from patients with gluten sensitive enteropathy were compared. There was no significant difference in the binding pattern of five lectins (Arachis hypogaea, Canavalia
The pathology of maldronksiekte, a sporadic neurological disorder of cattle caused by the ingestion of the plant Solanum kwebense in certain parts of South Africa, was studied in three chronic field cases. There was loss of cerebellar Purkinje cells with the remaining neurons either swollen or
The nucellus, which is the maternal tissue of the wheat grain, degenerates during the early stages of development. We have investigated whether or not this degenerative process may be considered as programmed cell death (PCD). The analysis of DNA of tissues dissected from developing wheat (Triticum
Recent studies suggest that chondroitin sulfate proteoglycans in the retinal interphotoreceptor matrix (IPM) play a role in maintaining photoreceptor viability. We report herein studies on the retinas from mice with mucopolysaccharidosis type VII (MPS VII), a storage disorder resulting from virtual
