“…In conclusion, none of the treatments at nonhardening temperatures could increase the freezing tolerance of rye seedlings at the two-to three-leaf stage beyond -9C, whereas exposure to low temperatures resulted in an LT 50 of -30C. Wilen et al (1994c) determined the effect of six racemic mixtures of ABA analogs on seedlings of Brassica napus L. and B. campestris L. grown at 10C. In B. napus, freezing tolerance could be increased 2C through the application of ABA aldehyde, 3´ dihydro ABA, or acetylenic divinyl methyl-ABA (Fig.…”

“…ABA treatment usually increases cold tolerance in stored plant material by increasing the expression of COR/LEA genes (Kobayashi et al 2008) and accumulation of proline (Dörffling et al 2009). A benefit for shoot survival is also displayed by ABA or/and proline pretreatment of Brassica campestris and B. napus (Wilen et al 1994), and Begonia x erythrophylla (Burritt 2008). However, pretreatment of (Capuana and Di Lonardo 2013).…”

Advances in biotechnology, especially in the field of in vitro culture techniques, led to the development of procedures that can be used as an excellent tool in plant conservation. The present study describes in vitro conservation of Senecio macrophyllus by slow-growth storage. Various sugar treatments, concentration of abscisic acid (ABA), light intensity and type of containers were tested. Viability and proliferation rate of shoots were evaluated 4 weeks after regrowth. The results obtained showed that polycarbonate boxes were a better type of containers for storage of S. macrophyllus shoots than glass vessels. Light negatively affected culture viability, multiplication rate and rooting response. In the case of Senecio macrophyllus the addition of ABA to storage medium stimulated survival and higher proliferation of shoots during regrowth in optimal conditions in comparison to shoots stored on medium without ABA. Shoots of S. macrophyllus were effectively stored for 6 months. All rooted shoots survived adaptation to field conditions and were able to flower in the second year after acclimatization.

“…However, due to the instability of ABA both in vivo and in vitro [22,23], the exogenous application of abscisic acid is somewhat limited. Over the past decades, numerous institutes, including our team, have focused on the development of new stable ABA analogs with better in vivo antimetabolite and in vitro anti-photo-isomerization activities [24][25][26][27]. In a previous study, we developed 2′,3′-iso-benzoabscisic acid (iso-PhABA), an excellent and easily prepared ABA analog that can inhibit metabolism in vivo [28].…”

Pigment content is an important quality attribute in the grape industry, and anthocyanins are the major fruit pigments. iso-PhABA is a novel and excellent ABA analog capable of the antimetabolic inactivation of ABA. In this study, we found that iso-PhABA improved the coloration of grape berries more obviously than ABA at concentrations of 2 mg/L and 5 mg/L in two grape varieties in China. iso-PhABA treatment enhanced the anthocyanin content in the two grape varieties; specifically, the anthocyanin and delphinidin contents increased in both the 'Jufeng' and 'Xiahei' varieties. An enzymatic activity test showed that iso-PhABA significantly promoted four key enzyme activities catalyzing anthocyanin biosynthesis. We also determined the affinity between iso-PhABA and ABA receptors using ABA as a control. The results indicated that iso-PhABA had significantly to moderately higher affinities for some ABA receptors, including PYR1, PYL2, PYL1, PYL3 and PYL10, which resulted in higher inhibition of the PP2C HAB1 in the presence of iso-PhABA than in the presence of ABA. iso-PhABA treatment increased the content of soluble sugars and grape yield without any apparent accompanying adverse effects on the quality of the grapes.
