Genetic and phenotypic characterization of global Lupinus albus genetic resources for the development of a CORE collection

Lupinus albus is a food grain legume recognized for its high levels of seed protein (30-40%) and oil (6-13%), and its adaptability to different climatic and soil conditions. To develop the next generation of L. albus cultivars, we need access to well-characterized, genetically and phenotypically diverse germplasm. Here we evaluated more than 2000 L. albus accessions with passport data based on 35 agro-morphological traits to develop Intelligent CORE Collections. The reference CORE (R-CORE), representing global diversity, exemplified the genotypic variation of cultivars, breeding/research materials, landraces and wild relatives. A subset of 300 R-CORE accessions was selected as a training CORE (T-CORE), representing the diversity in the entire collection. We divided the L. albus R-CORE into four phenotypic groups (A1, A2, A3 and B) based on principal component analysis, with groups A3 and B distinguished by pod shattering and seed ornamentation, respectively. The coefficient of additive genetic variation differed across morphological traits, phenotypic groups, geographic regions, and according to biological status. These CORE collections will facilitate agricultural research by identifying the genes responsible for desirable traits in crop improvement programs, and by shedding light on the use of orphan genetic resources for origin and domestication studies in L. albus. Understanding the variation in these genetic resources will allow us to develop sustainable tools and technologies that address global challenges such as providing healthy and sustainable diets for all, and contrasting the current climate change crisis.

The unexplored diversity of wild lupins provides rich genomic resources and insights into lupin evolution

Lupin crops provide nutritious seeds as an excellent source of dietary protein. However, extensive genomic resources are needed for the adaptation of lupin crops, particularly to improve their nutritional value and facilitate their adaptation to harsh environments caused by the changing climate. Such resources can be derived from crop wild relatives, which represent a large untapped source of genetic variation for crop improvement. Here we describe the first whole-genome sequences of the cross-compatible species Lupinus cosentinii (Mediterranean) and its pan-Saharan wild relative L. digitatus, which are well adapted to drought-prone environments and partially domesticated. We found that both species are tetraploids, with similar genome structures, distributions of gene duplications, and numbers of expanded and contracted gene families. The expansion and contraction of gene families that determine seed size, a paradigmatic domestication trait, indicates that gene duplication may have led to morphological adaptations in L. cosentinii and L. digitatus differing from those in L. albus, a domesticated lupin used as a reference. Seed size may therefore reflect convergent evolution mechanisms that play a key role in lupin domestication.

Socio-demographic determinants of monkeypox virus preventive behavior: a cross-sectional study in Pakistan

BackgroundMonkeypox, a re-emerging zoonotic infectious disease, is striking the world with serious public health concerns, especially in non-endemic countries. The publics knowledge and attitude toward the monkeypox virus (MPXV) influence their adherence to preventive strategies. Therefore, we aimed to assess the general publics knowledge, attitudes, and perceptions (KAP) of MPXV in Pakistan. MethodsWe collected data for this cross-sectional study from 1040 participants via an online self-reported questionnaire from 5th July 2022 to 1stAugust 2022. The questionnaire consisted of a total of 29 items in four sections, assessing socio-demographics, knowledge, attitudes, and practices regarding MPXV. The data was analyzed using IBM SPSS V.25, and factors associated with MPXV knowledge, attitude, and practices were identified by using logistic regression analyses ResultsA total of1040participants were included. 61.4% were male and 57.2% had graduation level education. Only 34.4% had good knowledge about MPXV and 30% were aware of effectiveness of smallpox vaccine against MPXV. 41.7% had positive attitude with 48.6% agreed that it is a fatal disease and 44.6% were in favor of banning travelling from endemic to non-endemic regions.57.7% had good practices and 69.9% would use protective measures if MPXV become an epidemic. Binary logistic regression analysis revealed that gender and education significantly impacted knowledge (p<0.05). While monthly income status had a significant impact on attitudes (p<0.05). The practices were correlated positively with gender and education (p<0.05). ConclusionThe majority of study participants had inadequate levels of knowledge, and attitudes regarding MPXV. To prevent the emergence and spread of MPXV in Pakistan, a comprehensive strategic framework for public health education must be established and implemented.
