Comparative transcriptomics reveals new insights into melatonin-enhanced drought tolerance in naked oat seedlings.

The growth and development of naked oat ( L.) seedlings, a grain recognized as nutritious and healthy, is limited by drought. Melatonin plays a positive role in plants under drought stress.

Effects of drought stress during critical periods on the photosynthetic characteristics and production performance of Naked oat (Avena nuda L.).

Revealing the effects of drought stress on the photosynthetic characteristics and yield of naked oats (Avena nuda L.) is significant for enhancing the productivity of oats. In this study, a potted experiment consisting of four water levels was conducted in the Bashang area of Hebei Province, China.

[Contrast-enhanced ultrasound imaging features of diabetic foot ulcers].

Objective: To investigate contrast-enhanced ultrasound imaging features of diabetic foot ulcers.

Methods: Sixteen patients with diabetic foot ulcers underwent conventional and contrast-enhanced ultrasound examinations, and the features of contrast-enhanced ultrasound imaging were analyzed. Pathological examination was also carried out in some cases.

Activation tagging, an efficient tool for functional analysis of the rice genome.

Over the past 6 years, we have generated about 50,000 individual transgenic rice plants by an Agrobacterium-mediated transformation approach with the pER38 activation tagging vector. The vector contains tandemly arranged double 35S enhancers next to the right border of T-DNA. Expression analysis by reverse transcription-PCR indicates that the activation efficiency is high if the genes are located within 7 kb of the inserted double 35S enhancers.
