Genome-wide expression of low temperature response genes in Rosa hybrida L.

Michele Valquíria Dos Reis, Laura Vaughn Rouhana, Ahmed Sadeque, Lucimara Koga, Steven J Clough, Bernanda Calla, Patrícia Duarte de Oliveira Paiva, Schuyler S Korban,

Plants respond to low temperature stress during cold acclimation, a complex process involving changes in physiological and biochemical modifications. The rose serves as a good model to investigate low temperature responses in perennial ornamentals. In this study, a heterologous apple microarray is used to investigate genome-wide expression profiles in Rosa ... Read more >>

Sex-Specific Markers for Waterhemp (Amaranthus tuberculatus) and Palmer Amaranth (Amaranthus palmeri)

Jacob S Montgomery, Ahmed Sadeque, Darci A Giacomini, Patrick J Brown, Patrick J Tranel,

Waterhemp [Amaranthus tuberculatus (Moq.) J. D. Sauer] and Palmer amaranth (Amaranthus palmeri S. Watson) are troublesome weeds of row-crop production in the United States. Their dioecious reproductive systems ensure outcrossing, facilitating rapid evolution and distribution of resistances to multiple herbicides. Little is known, however, about the genetic basis of dioecy ... Read more >>

Target-Site Resistances to ALS and PPO Inhibitors Are Linked in Waterhemp (Amaranthus tuberculatus)

Patrick J Tranel, Ahmed Sadeque, Chenxi Wu,

It is generally expected that, in the case of multiple herbicide resistance, different resistance mechanisms within a weed will follow Mendel's law of independent assortment. Research was conducted to investigate anecdotal observations suggesting that target site—based resistances to inhibitors of acetolactate synthase (ALS) and protoporphyrinogen oxidase (PPO) did not follow ...

PURPOSE: To determine the genetic cause of Bardet-Biedl syndrome (BBS) in two consanguineous Pakistani families. METHODS: Clinical characterization of the affected individuals in both families was performed with ophthalmic examination, electroretinography, electrocardiography, and liver and renal profiling. Seventeen genes are known to be associated with BBS, so exome sequencing was ... Read more >>

Association of ANRIL polymorphism (rs1333049:C>G) with myocardial infarction and its pharmacogenomic role in hypercholesterolemia.

Waqas Ahmed, Imran Saeed Ali, Moeen Riaz, Asma Younas, Ahmed Sadeque, Asfandyar Khan Niazi, Saad Hameed Niazi, Syeda Hafiza Benish Ali, Maleeha Azam, Raheel Qamar,

Single nucleotide polymorphisms (SNPs) of non-coding RNA in the INK4 locus (ANRIL) have been found to be associated with myocardial infarction (MI). However, the effect of rs1333049:C>G in INK4 locus in familial hypercholesterolemia patients and on lipid profile of the patients has not been studied in Pakistan. We therefore investigated ...

Novel and recurrent LDLR gene mutations in Pakistani hypercholesterolemia patients.

Waqas Ahmed, Muhammad Ajmal, Ahmed Sadeque, Roslyn A Whittall, Sobia Rafiq, Wendy Putt, Athar Khawaja, Fauzia Imtiaz, Nuzhat Ahmed, Maleeha Azam, Steve E Humphries, Raheel Qamar,

The majority of patients with the autosomal dominant disorder familial hypercholesterolemia (FH) carry novel mutations in the low density lipoprotein receptor (LDLR) that is involved in cholesterol regulation. In different populations the spectrum of mutations identified is quite different and to date there have been only a few reports of ... Read more >>

A novel pathogenic nonsense triple-nucleotide mutation in the low-density lipoprotein receptor gene and its clinical correlation with familial hypercholesterolemia.

Muhammad Ajmal, Waqas Ahmed, Naveed Akhtar, Ahmed Sadeque, Ayesha Khalid, Syeda Hafiza Benish Ali, Nuzhat Ahmed, Maleeha Azam, Raheel Qamar,

The aim of this study was to determine the genetic basis of familial hypercholesterolemia in a Pakistani family with a history of myocardial infarction and premature coronary artery disease.Direct sequencing of the low-density lipoprotein receptor gene resulted in the identification of a novel missense mutation c.264G>C (p.R88S) in exon 3 ...

Role of tissue plasminogen activator and plasminogen activator inhibitor polymorphism in myocardial infarction.

Waqas Ahmed, Meera Malik, Imran Saeed, Amina Ali Khan, Ahmed Sadeque, Umar Kaleem, Nuzhat Ahmed, Muhammad Ajmal, Maleeha Azam, Raheel Qamar,

A case-control association study on 229 Myocardial Infarction (MI) patients and 217 healthy controls was carried out to determine the role of tissue-plasminogen activator (t-PA) (Alu-repeat insertion (I)/deletion (D)) and plasminogen activator inhibitor (PAI-1) (4G/5G insertion/deletion) polymorphisms with MI in the Pakistani population. In MI patients the genotype distribution of ... Read more >>
