Ziziphus jujuba Mill. is one of the most important fruit crops and has been cultivated in China for more than 4000 years. Z. jujuba fruit is rich in nutritional and medicinal values. Compared to other wood fruits, Z. jujuba is unique in its flowering and fruiting characteristics. Floral buds differentiation and formation of Z. jujuba is an essential process that affects yield. Z. jujuba ‘Jinsi No.4’ blooms profusely, yet its final yield is low. In this study, the floral bud differentiation and development of ‘Jinsi No.4’ were examined by paraffin section. Results showed that the floral buds of ‘Jinsi No.4’ differentiated in the current year and started from early April. The duration of a single flower differentiation was short, taking only 7 days for maturation of flowers buds. Floral bud differentiation of ‘Jinsi No.4’ can be divided into six stages, i.e., pre-differentiation, initial differentiation, sepal differentiation, petal differentiation, stamen differentiation, and pistil differentiation. Flower development experienced seven stages, i.e., alabastrum, alabastrum break, sepal flattening, petal flattening, stamen flattening, filament withering, and ovule swelling. Dysplasia was observed in some floral organs in Z. jujuba ‘Jinsi No.4’, suggesting that the dysplasia of floral organs may be one of the main reasons for low yields. Our findings on flower bud development in ‘Jinsi No.4’ will contribute to its production and flowering management in Hunan area of southern China.

Vitamin A Deficiency (VAD) has been a public health problem among children in developing countries. To alleviate VAD, Vitamin A Supplementation (VAS), food fortification, biofortification and nutrition education have been implemented in various degrees of success with their own merits and limits. While VAS is the most widely utilized intervention in developing countries to ease the burden of VAD, some have raised questions on VAS’ effectiveness. Biofortification, often touted as an effective alternative to VAS, has received significant attention. Among the available biofortification methods, adopting transgenic technology has not only facilitated rapid progress in science for enhanced pro-Vitamin A (pVA) levels in target crops, but drawn considerable skepticism in politics for safety issues. Additionally, VAD-afflicted target regions of transgenic pVA crops widely vary in their national stance on Genetically Modified (GM) products, which further complicates crop development and release. This paper briefly reviews VAS and its controversy which partly demanded shifts to food-based VAD interventions, and updates the current status of transgenic pVA crops. Also, this paper presents a framework to provide potential influencers for transgenic pVA crop development under politically challenging climates with GM products. The framework could be applicable to other transgenic micronutrient biofortification.

Increased number of patients affected by metabolic syndrome (MS) has prompted the necessity of better understanding what is involved in such syndrome. Nevertheless, the establishment of promising therapies depends on the knowledge about the interaction of molecules within MS. In such context, Nitric Oxide (NO) emerges from a bulk of works relating its roles on aspects of MS, including cardiovascular diseases, their symptoms and comorbidities, which are thought to be triggered by similar sources. NO, nitric oxide synthase and enzymatic chains are keys for those disease and symptoms processes. NO has been separately described as part of hypertensive, ischemic and pain signaling. Although there are similar pathways likely shared for generating cardiovascular symptoms such angina, they are barely associated to NO in literature. The present review aims to clarify the patterns of NO alteration in metabolic syndrome directly concerned to cardiovascular symptoms, especially angina.
