Background: Engineering apomixis in sexually reproducing plants has been long desired because of the potential to fix hybrid vigor. Validating the functionality of genes originated from apomictic species that contribute to apomixis upon

Little is known about the cross talk between the lignin biosynthesis gene promoters and the regulatory proteins that modulate molecular signaling and respond to various stresses. In this study, we characterized the promoter region of the lignin biosynthesis pathway cinnamyl alcohol dehydrogenase

Two 1-year rotation experiments were conducted from 1998 to 2000 to assess the impact of forage and grain pearl millet (Pennisetum glaucum) on Pratylenchus penetrans populations in a tobacco field (Nicotiana tabacum cv. Delgold) in Quebec. Performance of these crops was compared with rye, the

In the present study, the promoter region of the pearl millet heat shock protein 10 (PgHsp10) gene was cloned and characterized. The PgHsp10 promoter (PgHsp10pro) sequence region has all the cis-motifs required for tissue and abiotic stress inducibility. The complete PgHsp10pro (PgHsp10PC) region

The Rab GTPases are important components of endocytic network in plant cells. Endocytosis participates in the cell's reaction to extracellular stimuli by desensitizing, down-regulating or recycling receptors and membrane proteins. Rab7 is a small GTP-binding protein involved in intracellular vesicle

We have cloned and characterized the cDNA, genomic clone and upstream promoter region of a vacuolar ATPase (V-ATPase) c subunit (PgVHA-c1) from Pennisetum glaucum. The deduced amino acid sequence shows 98-71% sequence identity with V-ATPase from rice and Arabidopsis, and is a highly hydrophobic

Mesophyll protoplasts and bundle-sheath cells of Pennisetum purpureum Schum., a C4 plant with low phenol-oxidase activity, were enzymatically separated according to methods recently developed with sugarcane (Saccharum officinarum L.), maize (Zea mays L.), and sorghum (Sorghum bicolor L.). The

Zea mays and Sorghum bicolor are important crops for animal and human nutrition worldwide. In the Central Highland Valley of Mexico, both crops are extremely important, and research is aimed toward increasing yield, disease resistance, and crop adaptation from 1,900- to 2,700-m elevation. In a

Necrosis at the leaf tips and margins of pearl millet (Pennisetum glaucum (L.) R. Br.) was observed in 1995 in a Pseudomonas syringae resistance screening nursery near Bulawayo, Zimbabwe. Straw-colored lesions with a chlorotic edge often extended the leaf length, and were atypical of the round

Pearl millet is a C₄ cereal crop that grows in arid and semi-arid climatic conditions with the remarkable abiotic stress tolerance. It contributed to the understanding of stress tolerance not only at the physiological level but also at the genetic level. In the present study, we

The incidence and prevalence of autism have increased during the past two decades. Despite comprehensive genetic studies the cause of autism remains unknown. This review emphasizes the potential importance of environmental factors in its causation. Alterations of cortical neuronal migration and

The DREB transcription factors comprise conserved ERF/AP2 DNA-binding domain, bind specifically to DRE/CRT motif and regulate abiotic stress mediated gene expression. In this study we show that PgDREB2A from Pennisetum glaucum is a powerful transcription factor to engineer multiple stress tolerance
