Crossability of Arachis valida and B genome Arachis species
, “Crossability of Arachis valida and B genome Arachis species”, vol. 14, pp. 17574-17586, 2015.
The peanut (Arachis hypogaea) is an important food crop in much of the tropical and semi-tropical parts of the world. The peanut is an allotetraploid with an AABB genome formula derived from diploids A. duranensis (A genome) and A. ipaënsis (B genome). The success of an introgression program that aims to improve cultivated varieties of the peanut depends on whether the chosen B genome species is homologous with the B genome of the peanut.
Segregation analysis of microsatellite (SSR) markers in sugarcane polyploids
, “Segregation analysis of microsatellite (SSR) markers in sugarcane polyploids”, vol. 14, pp. 18384-18395, 2015.
No information is available on segregation analysis of DNA markers involving both pollen and self-progeny. Therefore, we used capillary electrophoresis- and fluorescence-based DNA fingerprinting together with single pollen collection and polymerase chain reaction (PCR) to investigate simple sequence repeat (SSR) marker segregation among 964 single pollens and 288 self-progenies (S1) of sugarcane cultivar LCP 85-384. Twenty SSR DNA fragments (alleles) were amplified by five polymorphic SSR markers. Only one non-parental SSR allele was observed in 2392 PCRs.
A cytological study of anther and pollen development in Camellia oleifera
, “A cytological study of anther and pollen development in Camellia oleifera”, vol. 14, pp. 8755-8765, 2015.
The plant species Camellia oleifera is an important producer of edible oil in China. However, it suffers from a low fruit-setting rate. This study used high resolution scanning electron microscopy of semi-thin tissue sections to investigate anther development and pollen formation, and to determine whether problems in forming functional pollen cause low seed setting rates. During anther development, cell sizes within the epidermis and end othecium gradually increase, and at the beginning of the microsporocyte phase, the cells become highly vacuolated.
Overexpression of the CmACS-3 gene in melon causes abnormal pollen development
, “Overexpression of the CmACS-3 gene in melon causes abnormal pollen development”, vol. 14, pp. 10433-10443, 2015.
Sexual diversity expressed by the Curcurbitaceae family is a primary example of developmental plasticity in plants. Most melon genotypes are andromonoecious, where an initial phase of male flowers is followed by a mixture of bisexual and male flowers. Over-expression of the CmACS-3 gene in melon plants showed an increased number of flower buds, and increased femaleness as demonstrated by a larger number bisexual buds.
