Rice Growth

Improvements in yield and quality of rice are crucial for global food security. However, global rice production is substantially hindered by various biotic and abiotic stresses. Making further improvements in rice yield is a major challenge to the rice research community, which can be accomplished through developing abiotic stress-resilient rice varieties and engineering durable agrochemical-independent pathogen resistance in high-yielding elite rice varieties. This, in turn, needs increased understanding of the mechanisms by which stresses affect rice growth and development. Alternative splicing (AS), a post-transcriptional gene regulatory mechanism, allows rapid changes in the transcriptome and can generate novel regulatory mechanisms to confer plasticity to plant growth and development. Mounting evidence indicates that AS has a prominent role in regulating rice growth and development under stress conditions. Several regulatory and structural genes and splicing factors of rice undergo different types of stress-induced AS events, and the functional significance of some of them in stress tolerance has been defined. Both rice and its pathogens use this complex regulatory mechanism to devise strategies against each other. This review covers the current understanding and evidence for the involvement of AS in biotic and abiotic stress-responsive genes, and its relevance to rice growth and development. Furthermore, we discuss implications of AS for the virulence of different rice pathogens and highlight the areas of further research and potential future avenues to develop climate-smart and disease-resistant rice varieties.

<p>Although the livelihoods of the households in Doung Khpos commune are encompassed of different strategies, the dominant one is rice farming. The main water sources for rice farming in Doung Khpos commune are rainwater and canals, both of which are constrained by either seasonality or functionality. With unreliable water supplies for rice farming and frequent drought, water dependent livelihoods are exposed to higher threats.  Due to the non-availability and unpredictability of rainwater, the lack of water in the canals or the water commodification, some rice farmers were not able to grow rice all year round. The household income was reported to decrease; meanwhile some households had to borrow money to cover the household expenses. Some rice farmers coped with the household financial shortages by reducing the amount of food intake or asked the children to help with income generating activities which inevitably force them to skip or quit school. The growth and development of children could be impacted owing to the household economic insufficiency.  The majority of the rice farmers did not have solutions to cope with the water challenges for rice farming. With limited coping mechanism or capacity to deal with frequent flood and drought, in conjunction with no support in relation to water for rice farming from any stakeholders, the vulnerability of the rice farmers in Doung Khpos commune is high.  Improved water management, capacity building to the local community on climate change adaptation and disaster preparedness and water governance, are believed to enhance the livelihoods of the rice farmers in Doung Khpos commune.</p>

Abstract Background: Amino acids, which are transported by amino acid transporters, are the major forms of organic nitrogen utilized by higher plants. Among the 19 Amino Acid Permease transporters (AAPs) in rice, only a small number of these genes have been reported to influence rice growth and development. However, whether other OsAAPs are responsible for rice growth and development is unclear.Results: In this study, we demonstrate that OsAAP4 promoter sequences are divergent between Indica and Japonica, with higher expression in the former, which produces more tillers and higher grain yield than does Japonica. Overexpression of two different splicing variants of OsAAP4 in Japonica ZH11 significantly increased rice tillering and grain yield as result of enhancing the neutral amino acid concentrations of Val, Pro, Thr and Leu. OsAAP4 RNA interference (RNAi) and mutant lines displayed opposite trends compared with overexpresing (OE) lines. In addition, exogenous Val or Pro at 0.5 mM significantly promoted the bud outgrowth of lines overexpressing an OsAAP4a splicing variant compared with ZH11, and exogenous Val or Pro at 2.0 mM significantly enhanced the bud outgrowth of lines overexpressing splicing variant OsAAP4b compared with ZH11. Of note, the results of a protoplast amino acid-uptake assay showed that Val or Pro at different concentrations was specifically transported and accumulated in these overexpressing lines. Transcriptome analysis further demonstrated that OsAAP4 may affect nitrogen transport and metabolism, and auxin, cytokinin signaling in regulating rice tillering.Conclusion: Our results suggested that OsAAP4 contributes to rice tiller and grain yield by regulating neutral amino acid allocation through two different splicing variants and that OsAAP4 might have potential applications in rice breeding.

Biyukukung ceremony was carried out by Balinese people who worked in agriculture, especially rice farming. This ceremony was related with Balinese people’s effort religiously to gained prosperity for their rice in the field. As a rice farmer, Balinese people often had adversity in their field, liked damaged by pests, lacked of water, and more. As a religious people, they used this ceremony to avoid any adversity. Biyukukung ceremony was carried out by farmers, started from prepared the facilities like banten and other which related with the ceremony. The meaning of this ceremony was an expression of farmers’ thankful to God in the form of his manifestation as Dewi Sri and Dewa Wisnu which provided safety and growth the rice fertilely, protected from the pests, and other damaged. That was why Balinese people carried out the ceremony which had inherited by every generation. This ceremony also made different meaning of agriculture group, which was not only about farming. Moreover, the mean was combined the concept of Hindu’s theology and farming. This tradition then became a unified in farming system, so that the religion ceremony and farming activity be related to each other. Balinese people always depended to God for their safety, so that all of their action, included farming, was related. This relation made Bali unique, there was no line between religion and culture in their daily life. Thus, “Biyukukung Ceremony” had function and meaning to prayed the rice growth fertilely and also the field safety, so that the farmers could harvest well according to their expectation
