Solanum procumbens Lour. is a traditional medicinal plant known for its rich glycoalkaloid content. This research aimed to determine the suitable types and application rates of microbial organic fertilizers to enhance yield and glycoalkaloid content in Solanum procumbens Lour. A two-factor experiment was conducted using a Split-Plot Design (SPD) with three replications.

The study was conducted to determine the nitrogen use efficiency (NUE) and the ability to provide nitrogen from alluvial soil for growing pomelo (Citrus grandis L. Osbeck) in the Mekong Delta. The experiment was arranged in a randomized complete block design including two treatments (NPK treatment: 673 N - 385 P2O5 -192 K2O g/plant and PK treatment: 0 N - 385 P2O5 - 192 K2O g/plant) and three replicates (3 plants for each replicate).

The study including two experiments was arranged in a completely randomized design with two factors. For callus induction, the culture medium supplemented with concentrations of TDZ combined with concentrations of NAA was used, while to induce shoots, concentrations of BA combined with concentrations of NAA were added to the medium.

An experiment was conducted to generate a broad genetic variability through induced mutation using physical and chemical mutagens. Three doses each of gamma rays (20, 40 and 60kR), ethyl methane sulphonate (0.2, 0.4 and 0.6%), nitrosoguanidine (0.005, 0.010, and 0.015%), maleic hydrazide (0.01, 0.02 and 0.03%) and their combinations were administered to the seed of two greengram varieties, Sujata and OBGG-52.

Alternative strategies are needed in pest management to protect crops from pests. Occurrence of epiphytic lactic acid bacteria (LAB) on crop plants, especially on sites that are selected by pests, may be associated with host selection by insects. We carried out laboratory investigations as well as screen house and field experiments to understand whether epiphytic LAB occur at oviposition sites of agricultural and horticultural crops, probably modulating pest abundance by attraction or repulsion. The diversity of such epiphytic LAB associated with insect oviposition sites is discussed.

Agrobacterium tumefaciens is a Gram-negative, phytopathogenic bacterium and is characterized by an unique mode of action on dicotyledonous plants: it is able to genetically modify the host, and because of this feature, it is used as a tool for transgenic plants. Many experiments have demonstrated that lipopolysaccharides (LPSs) play an important role for the disease development, as they are involved in the adhesion process of the bacterium on the plant cell wall.

The properties of theD6 desaturase/acetylenase from the mossCeratodon purpureusand theD12 acetylenase from the dicotCrepis alpinawere studied by expressing the encoding genes inArabidopsis thalianaandSaccharomyces cerevisiae. The acetylenase fromC. alpinaD12 desaturated both oleate and linoleate with about equal efficiency. The desaturation of oleate gave rise to 9(Z),12(E)- and 9(Z),12(Z)-octadeca-dienoates in a ratio of approximately 3 : 1.

Potassium (K + ) is the most abundant inorganic cation in plant cells. Unlike animals, plants lack sodium⁄potassium exchangers. Instead, plant cells have developed unique transport systems for K + accumulation and release.
