India (8-30 N and 68-97.5 E) exhibits a wide range in topography and climate, which has a bearing on its vegetation and floristic composition. This subcontinent is one of the World’s 12 leading Biodiversity Centres, encompassing 16 different agro-climatic zones, 10 vegetation zones, 25 biotic provinces and about 426 habitats of specific species. It has been estimated that about 45,000 plant spe...

Most microorganisms of the phyllosphere are nonculturable in commonly used media and culture conditions, as are those in other natural environments. This review queries the reasons for their 'noncultivability' and assesses developments in phyllospere microbiology that have been achieved cultivation independently over the last 4 years. Analyses of total microbial communities have revealed a comp...

Baccharis dracunculifolia is the source of Brazilian green propolis (BGP). Considering the broad spectrum of biological activities attributed to green proplis, B. dracunculifolia has a great potential for the development of new cosmetic and pharmaceutical products. In this work, the cultivation of 10 different populations of native B. dracunculifolia had been undertaken aiming to determine the ...

INTRODUCTION A number of plant species, that have only rarely been cultivated in the past, are now being investigated for possible domestication in northern Europe. Species within the Rosaceous genus Chaenomeles (also referred to as the common name of these species) have received increased attention because of their high yield of fruits, which are rich in juice, aroma, and dietary fiber, and be...

Plant materials represent a strategic energy source because they can give rise to sustainable biofuels through the fermentation of their carbohydrates. A clear example of a plant-derived biofuel resource is the sugar cane bagasse exhibiting 60-80% of fermentable sugars in its composition. However, the current methods of plant bioconversion employ severe and harmful chemical/physical pretreatmen...

Sole carbon source utilization (SCSU) patterns and phospholipid fatty acid (PLFA) profiles were compared with respect to their potential to characterize root-inhabiting microbial communities of hydroponically grown crops. Sweet pepper (Capsicum annum cv. Evident), lettuce (Lactuca sativa cv. Grand Rapids), and four different cultivars of tomato (Lycopersicon esculentum cvs. Gitana, Armada, Arom...

The present work demonstrates the participation of polyamines (PAs) to improve direct regeneration and Agrobacterium-mediated transformation in soybean half-seeds. The inclusion of PAs to culture medium along with optimal plant growth regulators (PGRs) enhanced shoot induction [98.3 %; 4.44 µM N6-benzyladenine (BA) and 103.27 µM spermidine] and elongation [90.0 %; 1.45 µM gibberellic acid (GA3)...

By analyzing soybean structural and physiological characteristic sufficiently, the paper proposes a plant structural controllable modeling method for soybean. It selects the key structural factors firstly, and collects the relevant field data. Then it extracts the organ structure and position laws along with their vertical and horizontal change to establish controllable structural model. Combin...

Virus diseases are significant threats to modern agriculture and their control remains a challenge to the management of cultivation. The main virus resistance strategies are based on either natural resistance or engineered virus-resistant plants. Recent progress in understanding the molecular mechanisms underlying the roles of resistance genes has promoted the development of new anti-virus stra...
