Two Intra-Individual ITS1 rDNA Sequence Variants Identified in the Female and Male Populations of Alabama.

Around 300 different plant species are infected by the plant-parasitic reniform nematode (), including cotton. This is a devasting nematode with a preference for cotton; it is commonly found in Alabama farms and causes severe reduction in yields. Its first internal transcribed spacer (ITS1) region can be sequenced, and potential mutations can be found in order to study the population dynamics of the reniform nematode.

High-density DArTSeq SNP markers revealed wide genetic diversity and structured population in common bean (Phaseolus vulgaris L.) germplasm in Ethiopia.

Introduction: Common bean is one of the widely consumed food security crop in Africa, Asia, and South America. Understanding genetic diversity and population structure is crucial for designing breeding strategies.

Materials: Two hundred and eighty-nine germplasm were recently collected from different regions of Ethiopia and introduced from CIAT to estimate genetic diversity and population structure using 11,480 DArTSeq SNP markers.

Induced variations of ethyl methane sulfonate mutagenized cowpea ( L. walp) plants.

Unique variants are desired in the development of genetically improved crops to meet farmer and market needs hence ethyl methane sulfonate (EMS) was used to induce genetic variability in cowpea ( cv. ). The main objective of this research was to characterize induced variations in EMS chemically mutagenized population of cowpea ( L.

Drought Tolerance and Application of Marker-Assisted Selection in Sorghum.

Sorghum is an important staple food crop in drought prone areas of Sub-Saharan Africa, which is characterized by erratic rainfall with poor distribution. Sorghum is a drought-tolerant crop by nature with reasonable yield compared to other cereal crops, but such abiotic stress adversely affects the productivity. Some sorghum varieties maintain green functional leaves under post-anthesis drought stress referred to as stay-green, which makes it an important crop for food and nutritional security.

The gynoecious CmWIP1 transcription factor interacts with CmbZIP48 to inhibit carpel development.

In angiosperms, sex determination leads to development of unisexual flowers. In Cucumis melo, development of unisexual male flowers results from the expression of the sex determination gene, CmWIP1, in carpel primordia. To bring new insight on the molecular mechanisms through which CmWIP1 leads to carpel abortion in male flowers, we used the yeast two-hybrid approach to look for CmWIP1-interacting proteins.
