Tomato (Lycopersicon esculentum Mill.) ripening-associated membrane protein (TRAMP) is a channel protein of the membrane intrinsic protein (MIP) class encoded by the cDNA clone pNY507 [R.G. Fray et al. (1994) Plant Mol Biol 24: 539-543]. It has been suggested that these proteins encode water channels or aquaporins. TRAMP mRNA accumulated in all tomato tissues tested and was elevated in fruit during post-anthesis development and again during ripening. Transgenic plants that constitutively expressed a TRAMP antisense RNA sequence were generated with a 94% reduction of endogenous TRAMP mRNA in fruit. They showed no obvious phenotype that could be associated with gross perturbation of water relations, but ripening fruit of these plants showed marked alterations in the normal pattern of accumulation of both organic acids and sugars. At the onset and during ripening, levels of the organic acids L-malate and citrate were significantly elevated while levels of D[+]-glucose and D[+]-fructose were reduced. Additional transgenic lines were generated with reduced TRAMP mRNA, and the phenotype of increased acids and reduced sugars during fruit maturation and ripening was shown to be reproducible and stably inherited. Fruit of plants that over-expressed TRAMP mRNA showed no significant alteration in the sugars or acids investigated. These results suggest a role for TRAMP in the movement of solutes between cell compartments.

Moringa oleifera has been considered as a potential functional feed or food, since it contains multiple components beneficial to animal and human. However, little is known about the effects of Moringa oleifera supplementation on productive performances in sows. In the current study, the results showed that dietary Moringa oleifera significantly decreased the farrowing length and the number of stillborn (p < .05), while had an increasing trend in the number of live‐born (0.05 < p < .10). Furthermore, 8% Moringa oleifera supplementation significantly elevated protein levels in the colostrum (p < .05); 4% Moringa oleifera lowed serum urea nitrogen of sows after 90 days of gestation (p < .05) and significantly decreased serum glucose on 10 days of lactation (p < .05). Both groups showed significant elevation in serum T‐AOC activity (p < .05). The serum malondialdehyde (MDA) of sows declined significantly in 4% Moringa oleifera addition group (p < .05). 8% Moringa oleifera meal significantly elevated serum CAT activity after 60 days of gestation (p < .05), while decreased the serum MDA level and increased the serum GSH‐Px activity of sows at 10 days of lactation (p < .05). Of piglets, both two dosages of Moringa oleifera supplementation essentially reduced the serum urea nitrogen (p < .05), and 4% Moringa oleifera meal increased serum total protein (p < .05). In addition, piglets that received 8% Moringa oleifera had the highest serum CAT and SOD activities among all groups (p < .05). The present study indicated that Moringa oleifera supplementation could enhance the reproduction performances, elevate protein levels in the colostrum and improve the serum antioxidant indices in both sows and piglets.
