The present results suggest that there is no discrepancy testis-biased, testis-specific, andiscrepancy testis-biasedl genes are all uniformly distributed.
Thus, it is possible that misexpression of male-fertility-essential genes involved in spermatogenesis caused sterility in these hybrids.
Sorghum has the highest water use efficiency among major crop plants and is unusually tolerant to low soil fertility, traits essential for survival and productivity in arid and semi-arid areas with limited irrigation capability.
However, few studies have addressed the importance of internal reproductive organ size to other components of male reproductive success, or the significance of size variation in accessory reproductive organs which are often vital for sperm transfer, fertility, and essential for success in sperm competition [ 8, 9].
Manure and compost improve the ability of the soil to hold moisture and improve fertility--essential in drought conditions.
Reproduction makes money, so fertility panic is essential to keep queues for IVF and its associated methods ever longer.
As a result, off-farm activities and soil fertility improvement are essential to reduce the adverse impacts of population pressure on natural resource base.
Thus, assessing land use induced changes on soil properties and subsequent implication on soil fertility status is essential for understanding the influence of agro-ecosystem transformation on soil productivity and to indicate appropriate and sustainable soil and land management options.
Fertilizers and feed additives manufactured using sorption technology contain elements such as N, P, Cu, Mn, and Zn, which improve soil fertility and provide essential nutrients to animals and humans.
However, to ensure women full right to control their fertility, it is essential that both safe abortion and modern contraception is available, accessible and affordable for all women.
Finding a high mutation frequency of TEX11 among infertile men is not entirely unexpected: TEX11 is X-linked, such that any inherited or de novo mutations that impair the function of this essential fertility factor would manifest as infertility.
