Traditional maize possesses low concentrations of provitamin-A and vitamin-E, leading to various health concerns. Mutant alleles of and that enhance β-carotene (provitamin-A) and α-tocopherol (vitamin-E), respectively, in maize kernels have been explored in several biofortification programs. For genetic improvement of these target nutrients, uniplex-PCR assays are routinely used in marker-assisted selection.

Copy number variations (CNVs) have become widely acknowledged as a significant source of genomic variability and phenotypic variance. To understand the genetic variants in horses, CNVs from six Indian horse breeds, Manipuri, Zanskari, Bhutia, Spiti, Kathiawari and Marwari were discovered using Axiom Equine Genotyping Array. These breeds differed in agro-climatic adaptation with distinct phenotypic characters.

Beyond storage capacity, long-term grain storage faces significant challenges due to the activity of lipoxygenases (LOXs). These enzymes catalyze the production of volatiles from free fatty acids, leading to stale odors and off-flavors. These changes degrade the quality of stored grains, even under regulated conditions, affecting the profitability of stored products to the farmers and the assurance of high-quality food for consumers.

The major limiting factor of photosynthesis in C3 plants is the enzyme, rubisco which inadequately distinguishes between carbon dioxide and oxygen. To overcome catalytic deficiencies of Rubisco, cyanobacteria utilize advanced protein microcompartments, called the carboxysomes which envelopes the enzymes, Rubisco and Carbonic Anhydrase (CA). These microcompartments facilitate the diffusion of bicarbonate ions which are converted to CO by CA, following in an increase in carbon flux near Rubisco boosting CO fixation process.

Small RNA sequencing analysis in two chickpea genotypes, JG 62 (Fusarium wilt-susceptible) and WR 315 (Fusarium wilt-resistant), under Fusarium wilt stress led to identification of 544 miRNAs which included 406 known and 138 novel miRNAs. A total of 115 miRNAs showed differential expression in both the genotypes across different combinations. A miRNA, Car-miR398 targeted copper chaperone for superoxide dismutase (CCS) that, in turn, regulated superoxide dismutase (SOD) activity during chickpea-Foc interaction.

Article Synopsis
  • A team of over 180 researchers from more than 40 countries is addressing the issues related to "phantom agents," which are proposed pathogenic agents that are listed without concrete evidence of their existence.
  • These phantom agents, identified only through symptoms and lacking proper isolates or genetic data, create obstacles for trade and plant certification, making effective detection and risk assessment difficult.
  • The researchers recommend removing these agents from regulatory lists and updating standards in line with modern diagnostic methods to facilitate germplasm exchange and support global agriculture.

: Harzianum Clade in Soils from Central and South America.

J Fungi (Basel)

November 2024

Molecular Plant Pathology Laboratory, Agricultural Research Service, United States Department of Agriculture, Beltsville, MD 20705, USA.

As environmental and health concerns increase, the trend toward sustainable agriculture is moving toward using biological agents. About 60% of all biological fungicides have species as the active ingredient, with as the most common species in these products. However, the name has often been used incorrectly in culture collections, databases, and scientific literature due to the division of the Harzianum clade (HC) into more than 95 cryptic species, with only one being named .

December 2024

Department of VLSI Microelectronics, Saveetha School of Engineering, Saveetha Institute of Medical and Technical Sciences (SIMATS), Saveetha University, Chennai, 602105, Tamil Nadu, India.

Knowledge of soil temperature (ST) is important for analysing environmental conditions and climate change. Moreover, ST is a vital element of soil that impacts crop growth as well as the germination of the seeds. In this study, four machine-learning (ML) paradigms including random forest (RF), radial basis neural network (RBNN), multi-layer perceptron neural network (MLPNN), and co-active neuro-fuzzy inference system (CANFIS) were used for estimation of daily ST at different soil depths (i.

In recent years, the fall armyworm, has rapidly emerged as a global invasive pest, challenging the maize production and leading to considerable economic losses. Developing resistant hybrids is essential for sustainable maize cultivation, which requires a comprehensive understanding of resistance traits and the underlying mechanisms in parental lines. To address this need, the present study aimed to identify the sources of resistance, age and stage-specific effects and role of phytochemicals in plant defense against in thirty diverse maize parental lines [17 female (A) and 13 male (R) lines].

The retention and mobility of arsenic (As) in soil depend on various physical and chemical factors. The knowledge of the sorption-desorption chemistry of As in soil is necessary for predicting the fate and behavior of As in soil environments. Therefore, this study assessed different organic (sugarcane bagasse and vermicompost) and inorganic amendments (steel slag and fly ash) for their impact on sorption-desorption of As in texturally different contaminated soils (of sandy clay (SC) and sandy clay loam (SCL) texture) to understand the effect of amendments on As retention and mobility.
