Rice is a staple food for the people of Asia that supplies more than 50% of the food energy globally. It is widely accepted that the crop domestication process has left behind substantial useful genetic diversity in their wild progenitor species that has huge potential for developing crop varieties with enhanced resistance to an array of biotic and abiotic stresses. In this context, Oryza rufipogon, Oryza nivara and their intermediate types wild rice germplasm/s collected from diverse agro-climatic regions would provide a rich repository of genes and alleles that could be utilized for rice improvement using genomics-assisted breeding. Here we present a database of detailed information on 614 such diverse wild rice accessions collected from different agro-climatic zones of India, including 46 different morphological descriptors, complete passport data and DNA fingerprints. The information has been stored in a web-based database entitled 'Indian Wild Rice (IWR) Database'. The information provided in the IWR Database will be useful for the rice geneticists and breeders for improvement of rice cultivars for yield, quality and resilience to climate change.Database URL: http://nksingh.nationalprof.in: 8080/iwrdb/index.jsp.

Unlabelled: Previous studies illustrated that two banana GA20 oxidase2 (MaGA20ox2) genes, and , are implicated in controlling banana growth and development; however, the biological function of each gene remains unknown. Ma04g15900 protein (termed MaGA20ox2f in this article) is the closest homolog to the Rice SD1 (encoded by 'green revolution gene', ) in the banana genome. The expression of is confined to leaves, peduncles, fruit peels, and pulp.

Enhancing drought resistance through the manipulation of root system architecture (RSA) in crops represents a crucial strategy for addressing food insecurity challenges. Abscisic acid (ABA) plays important roles in drought tolerance; yet, its molecular mechanisms in regulating RSA, especially in cereal crops, remain unclear. In this study, we report a new mechanism whereby ABA mediates local auxin biosynthesis to regulate root gravitropic response, thereby controlling the alteration of RSA in response to drought in cereal crops.

Chromatin remodeling plays a crucial role in controlling gene transcription by modifying chromatin structure. However, the involvement of chromatin remodeling in plant stress responses, especially cold tolerance, through chromatin accessibility remains largely unexplored. Here, we report that rice (Oryza sativa L.

Glucose-6-phosphate isomerase (PGI), a key enzyme that catalyzes the reversible conversion of glucose-6-phosphate and fructose-6-phosphate, plays an important role in plant growth, development, and responses to abiotic stresses and pathogen infections. However, whether and how PGI modulates herbivore-induced plant defenses remain largely unknown. The Brown planthopper (BPH, ) is a devastating insect pest of rice, causing significant damage to rice plants through feeding, oviposition, and disease transmission, resulting in great yield losses.

Members of the B-Box (BBX) family of proteins play crucial roles in the growth and development of rice. Here, we identified a rice BBX protein, Oryza sativa BBX2 (OsBBX2), which exhibits the highest expression in the root. The transcription of follows a diurnal rhythm under photoperiodic conditions, peaking at dawn.
