Plant mitochondrial transcription termination factor (mTERF) genes comprise a large family with important roles in regulating organelle gene expression. In this study, a comprehensive database search yielded 31 potential mTERF genes in maize (Zea mays L.) and most of them were targeted to mitochondria or chloroplasts. Maize mTERF were divided into nine main groups based on phylogenetic analysis...

For maize (Zea mays L.), early planting date could be of advantage to high yields but a review of planting date effect on high-yielding data is not yet available. Following this rationale, a synthesis-analysis was conducted from the farmer annual maize contest-winner data (n = 16171 data points; 2011-2016 period); cordially provided by the National Corn Growers Association and a scientific lite...

The field experiments were conducted during 2017-19 at the ICAR-Indian Agricultural Research Institute, New Delhi, India. main aim of study was to find out a suitable cropping system that can replace existing rice-wheat realize higher productivity and profitability. Four systems, viz. rice (Oryza sativa L.) - mustard (Brassica juncea mungbean (Vigna radiata L.), maize (Zea mays mustard-mungbean...

On September 20, 2002, the National Science Foundation (NSF) announced the launch of the Maize Genome Sequencing Project. The momentum for this endeavor has been building within the maize (Zea mays) genetics and larger plant science community for several years. Reasons for launching a concerted effort at this time are at least 4-fold. First, advances in DNA sequencing technology now allow faste...

Maize (Zea mays) is one of the important food crops of India with other potential uses in preparation of livestock feed and biofuel. But production of maize in India is low compared to top maize producing countries due to abiotic stresses (Ranum et al., 2014). Among abiotic stresses affecting maize production in India, drought is the major limiting factor. In spite of extensive research on drou...

It was reported previously that enolase enzyme activity and ENO1 transcript levels are induced by anaerobic stress in maize (Zea mays). Here we show that not all isoforms of maize enolase are anaerobically induced. We cloned and sequenced a second enolase cDNA clone (pENO2) from maize. Sequence analysis showed that pENO2 shares 75.6% nucleotide and 89.5% deduced amino acid sequence identity wit...

A three-phase discontinuous sucrose gradient yielded two fractions of chloroplast envelope membranes from spinach (Spinacia oleracea L.), sunflower (Helianthus annuus L.), and maize (Zea mays L., mesophyll and undifferentiated chloroplasts). These species were selected to represent plants with fast photorespiration and slow net photosynthesis, fast photorespiration yet fast net photosynthesis, ...

Zea mays chloroplast DNA-dependent RNA polymerase in vitro preferentially transcribes maize chloroplast DNA sequences incorporated in cloned chimeric bacterial plasmids. Preferential transcription is dependent on the presence of a 27.5-kilodalton polypeptide, the S factor, which has been purified from maize chloroplasts, and also on the template's being in the supercoiled form.

Sunflower is a potent allelopathic plant which possesses important allelochemicals with known allelopathic activity on other plants. In this study, allelopathic effects of fresh aqueous extracts (FAE) and air dried aqueous extracts (DAE) of root, shoot and leaves of sunflower (Halianthus annuus L.) were investigated on germination and seedling growth of wheat (Triticum aestivum L.) and maize (Z...
