Genetic variability in Malacomeles denticulata (Rosaceae) from central Mexico revealed with SSR markers

Alternative berry crops belonging with the Rosaceae family currently have a great importance in the US and Canadian agribusiness, in this sense, the Mexican serviceberry (Malacomeles denticulata) is a fruit shrub mainly distributed in Mexico that has potential uses like horticultural crop; however, little information about its variability has been reported. That is why this research aims to determine the variability of M. denticulata by SSR markers. The apple SSR markers had a good transferability to Malacomeles (74 %); all transferable SSR are polymorphic and sixteen of them had high values of polymorphic information content, Nei's expected heterozygosity (He), and Shannon's information index (I), even the apple SSR loci were not previously proved in this species. Besides it was found high variability in the germplasm of central Mexico mainly within populations (72 %), where three different genetic pool were detected suggesting that a breeding program could be based in individual selection. That is why it is necessary select outstanding individual into population before to make hybridizations among these selected parents. � 2013 Springer Science+Business Media Dordrecht

Recent developments in Lablab purpureus genomics: A focus on drought stress tolerance and use of genomic resources to develop stress-resilient varieties

This research article published by John Wiley & Sons, Inc., 2021Drought is a major climatic challenge that contributes significantly to the decline of food productivity. One of the strategies to overcome this challenge is the use of drought-tolerant crops with a wide range of benefits. Lablab is a leguminous crop that has been showing high promise to drought tolerance. It is reported to have higher drought resilience compared with the commonly cultivated legumes such as common beans and cowpeas. Because of its great genetic diversity, Lablab can withstand high temperature and low rainfall, unlike other related crops. On top of that, it is grown for multitudes of purposes including food, forages, conservation agriculture, and improved soil fertility. To enhance its production and benefits during the present effects of climate change, it is crucial to develop improved varieties that would overcome the challenge of drought stress. In the past years, there have been several reviews on Lablab based on origin, domestication, characterization, utilization, germplasm conservation, some cultivation constraints, and conventional breeding with limitations on the genomic exploitation of the crop for drought tolerance. Conventional breeding is the major breeding technique for many Lablab cultivars. The integration of genomic, physiological, biochemical, and molecular approaches would be required to develop drought-tolerant cultivars of Lablab. In this review, we discuss recent developments in Lablab genomics with a focus on drought stress tolerance and the use of genomic resources to develop stress-resilient varieties
