Pearl millet (Cenchrus americanus) is a cereal crop that can tolerate high temperatures, drought, and low-fertility conditions where other crops lose productivity. However, genes regulating this ability are largely unknown. Transcription factors (TFs) regulate transcription of their target genes, regulate downstream biological processes, and thus are candidates for regulators of such tolerance of pearl millet.

Article Synopsis
  • Foliar diseases like late leaf spot (LLS) and leaf rust (LR) negatively impact groundnut yields and fodder quality, while a high oleic acid content is increasingly valued for its health benefits and extended shelf life.
  • Genetic mapping identified key resistance genes (LLSR1, LLSR2, and LR1) against these diseases, leading to the development of 49 KASP markers, with 41 successfully validated for use in breeding programs.
  • The study successfully implemented KASP assays to enhance resistance against LLS and LR in groundnuts, resulting in the release of several disease-resistant and high-oleic acid varieties in India.

A community-level nutritional intervention was implemented among tribal children (3 to 6 years of age) in Telangana, India. The one-year intervention involved six nutrient-rich formulations of millet-pulse-groundnut-based products suited to local taste preferences. Anthropometric measurements of height, weight, and mid-upper-arm circumference (MUAC) along with haemoglobin (Hb) levels were monitored at baseline and endline.

India's indigenous groups remain vulnerable to malnutrition, despite economic progress, reflecting the reliance on traditional agriculture and the problems of poverty and inadequate education and sanitation. This mixed-methods study analyzed the incidence, causes and determinants of chronic malnutrition, measured through stunting, thinness and underweight among adolescent indigenous girls in Telangana. Using 2017 data on 695 girls aged 11-18 years from 2542 households, the analysis showed that 13% had normal nutritional status, while 87% were stunted, underweight or thin.

Ethylene regulates auxin-mediated root gravitropic machinery and controls root angle in cereal crops.

Plant Physiol

June 2024

Joint International Research Laboratory of Metabolic and Developmental Sciences, State Key Laboratory of Hybrid Rice, SJTU-University of Adelaide Joint Centre for Agriculture and Health, School of Life Sciences and Biotechnology, Shanghai Jiao Tong University, Shanghai 200240, China.

Root angle is a critical factor in optimizing the acquisition of essential resources from different soil depths. The regulation of root angle relies on the auxin-mediated root gravitropism machinery. While the influence of ethylene on auxin levels is known, its specific role in governing root gravitropism and angle remains uncertain, particularly when Arabidopsis (Arabidopsis thaliana) core ethylene signaling mutants show no gravitropic defects.

Twenty-eight QTLs for LLS disease resistance were identified using an amphidiploid constructed mapping population, a favorable 530-kb chromosome segment derived from wild species contributes to the LLS resistance. Late leaf spot (LLS) is one of the major foliar diseases of peanut, causing serious yield loss and affecting the quality of kernel and forage. Some wild Arachis species possess higher resistance to LLS as compared with cultivated peanut; however, ploidy level differences restrict utilization of wild species.
