Abstract Northern Italy is an area particularly suitable for the cultivation of different crops. It used to be characterized by a high agrobiodiversity. However, it estimated that over last decades, this experienced genetic erosion more than 95%, resulting in loss many traditional plant resources (PGR).

Waterlogging stress causes substantial destruction to plant growth and production under climatic fluctuations globally. Plants hormones have been widely explored in numerous crops, displaying an imperative role crop defense mechanism. However, there is a paucity of research on the subject regulating waterlogging responses wheat crop. In this study, we clarified 6-BA through inducing phenylpropanoid biosynthesis wheat. The application (6-benzyladenine) enhanced development plants stress, which was accompanied by reduced electrolyte leakage, high chlorophyll, soluble sugar content. ROS scavenging also 6-BA, resulting MDA H

Abstract Wheat ( Triticum spp.) is a primary dietary staple food for humanity. Many wheat genetic resources with variable genomes have record of domestication history and are widespread throughout the world. To develop elite varieties, agronomical stress‐responsive trait characterization foremost evaluating existing germplasm to promote breeding. However, genomic complexity one impediments mining characterization. Multiple reference cutting‐edge technologies like haplotype mapping, selection, precise gene editing tools, high‐throughput phenotyping platforms, high‐efficiency transformation systems, speed‐breeding facilities transforming functional genomics research understand diversity polyploidy. This review focuses on achievements in genomics, available omics approaches, bioinformatic developed past decades. Advances system biology approaches highlighted circumvent bottlenecks phenotypic as well transfer. In addition, we propose conducting studies developing sustainable breeding strategies wheat. These developments understanding traits speed up creation high‐yielding, stress‐resistant, nutritionally enhanced which will help addressing global security agricultural sustainability era climate change.

Access to high‐yielding germplasm increases agricultural productivity. Plant Variety Protection (PVP) is the most globally used form of Intellectual Property Protection. Commercially available varieties protected solely by PVP can be accessed for further breeding within country or region protection. Unlike practice in other countries, USDA has a policy providing parental inbred lines hybrids into public domain following expiration their protection PVP. Parental and utility patents are also These distributions represent fresh opportunities researchers, hybrid seed producers plant breeders, nationally internationally. As contribution continuing debate over ownership access we report maize ( Zea mays L.) US National Germplasm System (NPGS). During 1988–2015 NPGS distributed 251,926 packets 7,582 requestors, fulfilling 10,432 orders. Distributions were primarily entities (87%), with 32,520 (13%) total 79 foreign countries. Of reported here, 45,968 (18%) expired off‐PVP germplasm.

Allozyme genetic variation in 12 populations of the endangered Castanea pumila var. (Allegheny chinkapin), sampled across natural range species United States, was evaluated using 11 loci from seven enzyme systems. At level, percentage polymorphic (Ps) 72·7 %, mean number alleles per locus (As) 1·9, (APs) 2·3, effective (Aes) 1·5 and diversity (Hes) 0·296. population Pp = 49·2 Ap 1·5, Aep 1·4, APp 2·1 Hep 0·21. Most allozyme (70 %) C. occurred within populations. Wright’s gene flow rate [Nm(W)] as low 0·57. Population differentiation along not detected. Populations Florida had most variable levels diversity, but Virginia Mississippi also showed high levels. Based on results this study, conservation management strategies are discussed.
